A case report of pediatric-onset MS associated uveitis

BackgroundTo report a case of Pediatric-onset MS associated uveitis managed with local and systemic medications.Case presentationAn 11-year-old boy who was diagnosed with Pediatric-onset MS (POMS) with the first presentation of left optic neuritis in another center, was referred to our clinic with the complaint of non-improved vision in the left eye despite receiving IV 5gr methylprednisolone. After the ophthalmologic examinations, the patient was diagnosed as bilateral POMS-associated intermediate uveitis, and local treatment with corticosteroid was administered to both eyes. He was continued on systemic therapy such as Rituximab and five sessions of plasmapheresis. After four months, the patient's vision improved from FC at 50cm to 9/10 in the left eye. The intensity of intraocular inflammation decreased in both eyes. In fluorescein angiography findings, the optic disc, as well as vascular leakage, subsided bilaterally.ConclusionDespite its rarity, POMS-associated uveitis presents a considerable challenge that necessitates the collaborative efforts of neurologists and ophthalmologists to achieve the most effective treatment outcomes.

Ultrawidefield Fluorescein Angiography and OCT Findings in Children and Young Adults with Autosomal Dominant Neovascular Inflammatory Vitreoretinopathy

PurposeAutosomal dominant neovascular inflammatory vitreoretinopathy (ADNIV) is a rare genetic (CAPN5) autoimmune condition typically diagnosed in adulthood and characterized by a triad of inflammation, retinal degeneration and neovascularization. We report novel multimodal imaging findings in children and young adults with ADNIV and early treatment response to short-duration local and/or systemic corticosteroids. DesignRetrospective consecutive case series. ParticipantsTen patients under the age of 25 with ADNIV and available multimodal imaging. MethodsThe medical records of patients under the age of 25 with a diagnosis of ADNIV with ultra-widefield fluorescein angiography (UWFFA) and optical coherence tomography (OCT) data were reviewed. Main Outcome MeasuresUWFFA and OCT findings at baseline and following local corticosteroids. ResultsMedian age at presentation was 14 years (range 9-24 years). OCT on presentation demonstrated CME in 8/20 eyes and symptomatic vitreoretinal interface disease in 2/20 eyes. Initial UWFFA demonstrated retinal vascular leakage (20/20 eyes, 100%), peripheral non-perfusion (13/20 eyes, 65%), and retinal neovascularization (6/20 eyes, 30%). Retinal vascular leakage improved with local corticosteroids and neovascularization regressed with anti-VEGF therapy. ConclusionsUWFFA findings of prefibrotic ADNIV reported in adults were also present in children and young adults. Early testing for a pathogenic CAPN5 variant in at-risk children and regularly scheduled screening for uveitis and retinal vasculitis with UWFFA and OCT may prompt earlier intervention. Short duration local steroids are effective at treating retinal vascular leakage and macular edema but are not durable suggesting a potential role for steroid-sparing immunosuppressive therapy. Early treatment may alter the natural history of disease.

Post-fever Retinitis With a Positive Weil-Felix Test: A Study From a Tertiary Center in South India.

Background Post-fever retinitis (PFR) is reported two to six weeks after fever and affects one or both eyes. Rickettsial fever is one of the most common causes of PFR. This study aimed to report the clinical features and treatment outcomes of PFR cases with a positive Weil-Felix test. Methodology In this study, we collected demographic data, fever details, eye symptoms, ocular examination findings, optical coherence tomography (OCT) and fundus fluorescein angiography findings, laboratory findings, and length of follow-up of consecutive PFR cases with a positive Weil-Felix test. All cases were treated with oral doxycycline and prednisolone. Final best-corrected visual acuity (BCVA) and ocular examination findings were recorded. Visual field examination and follow-up OCT results were noted if available. Results A total of nine patients (eight males) with a mean age of 39.1 years with fever before ocular symptoms and positive Weil-Felix test were included.Six patients had bilateral disease. The mean initial and final BCVA in the affected eyes was 1.16 and 0.35 logMAR units, respectively (p < 0001). All 15 eyes had typical white retinitis patches and retinal hemorrhages which resolved after treatment. OCT showed hyperreflectivity and inner retinal disorganization over retinitis patches. White subretinal lines were noted in three patients and retinal nerve fiber bundle defect with corresponding visual field defect was seen in one eye. Conclusions In this study, PFR due to rickettsia infections has been reported from our region for the first time. Hence, eye specialists in the region should be aware of this entity.

Ridge‐shaped peripapila dry, fluid associated, and self‐resolved fluid associated presentations

Purpose: We aim to describe three different clinical presentations of ridge‐shaped peripapilla.Methods: A series of case reports. Fundus images, autofluorescence (AF), optical coherence tomography (OCT) Angio‐OCT, indocyanine (ICG) and fluorescein angiography (FA) was performed.Results: The first case is a 55‐year‐old woman, that was referred to the clinic due to central visual acuity loss in her left eye. RPE atrophy, and a scleral nasal protrusion (same configuration on both eyes) with a thinned overlying choroid, with subretinal fluid around the peripapillary area and the submacular area was observed on the OCT. FA and ICG with no hotspots, nor any dilated choroidal vascular pattern was observed, nor any signs of a neovascular membrane (NVM). On FA patched hypoAF was observed around the nasal retina. Posterior staphyloma was corroborated with ocular echography. Four months after initial presentation, fluid resolved spontaneously, visual acuity improved, but fundus pigmentary defects remained unchanged. The second case is a 60 year‐old woman (OS), peripapillary subretinal fluid was observed on the oct, choroidal thinning and scleral protrusion nasal to the optic disc. The third case, a 70‐year‐old male (OD), showed a temporal whitish lesion, engorged scleral protrusion was seen on oct, with overlying RPE atrophy, very thinned choroid and retina, without subretinal fluid.Conclusions: Pathologic myopia is defined as myopic refractive error greater than −6.00 diopters. Many chorioretinal findings have been described regarding this condition, one of these is a ridge shaped peripapilla, a form of scleral protrusion around the optic disc. These patients presented on the fluorescein angiography and OCT findings, signs of protrusion of the sclera that seemed to result in overlying choroidal thinning with choroidal blood flow disturbances, and consequent RPE atrophy, leading to the subretinal fluid accumulation.

Evaluation of retinal vascularization in retinopathy of prematurity regressed after intravitreal ranibizumab monotherapy or without treatment based on fluorescein angiography

To investigate the fluorescein angiography (FA) findings and compare the extent of retinal vascularization in retinopathy of prematurity (ROP), recovered after intravitreal ranibizumab (IVR) monotherapy and those regressed spontaneously. Infants with a history of ROP who underwent FA between April 2018 and November 2021 were retrospectively included. The patients were divided into two groups based on whether they had received IVR (IVR group) or had ROP that regressed spontaneously without treatment (untreated group). The differences between the two groups in zone II ROP were also compared, to equalize the subgroups as much as possible in terms of disease severity. FA findings were recorded. The extent of vascularization was measured by the ratio of the distance from the center of the disk to the border of the vascularized zone (DB) and the distance from the center of the disk to the center of the fovea (DF). The width of the persistent avascular retina (PAR) was counted by disc diameters (DD). One hundred and ten eyes of 55 infants were included in the IVR group and 76 eyes of 38 babies in the untreated group. The ratio of abnormal shape of vessels was significantly higher in the IVR group than in the untreated group (50.9% vs. 35.5%; P = 0.038), while the linear choroidal filling pattern, tortuosity of vessels over the posterior pole, dye leakage, anomalous branching of vessels, circumferential vessels, arteriovenous shunt, abnormal capillary bed, and macular abnormalities were similarly. There was a smaller temporal DB/DF ratio (4.48 vs. 4.63; P = 0.003) and greater PAR (2.63 vs. 1.76; P < 0.001) in the IVR group compared to the untreated group. In zone II ROP, the progression of retinal vascularization was significantly larger in the IVR group than that in the untreated group (P = 0.003), while no statistical differences were observed in FA features, the DB/DF ratio, and PAR between the two subgroups. The residual vascular abnormalities and PAR may be common results of ROP regression. The DB/DF ratio of 4.0 temporally and 3.3 nasally could be used as the preliminary indicators for safe retinal vascularization in the completion of ROP regression.

Ocular features associated with mutations in ATOH7 gene overlap those with familial exudative vitreoretinopathy.

To report the ocular findings in 3 patients with a mutation in the ATOH7 gene. The clinical findings were collected from the medical records including those for magnetic resonance imaging (MRI). Genetic testing of the ATOH7 gene was performed. Three patients of two families who had poor vision since infancy were studied. The 3 patients had varying degrees of intraocular vascular proliferation associated with advanced retinal detachments as falciform retinal folds or total retinal detachments. This state is referred to as congenital retinal nonattachment. One eye of a sibling had fluorescein angiographic findings of excessive branching of the retinal vessels and fluorescent dye leakage that were consistent with those of familial exudative vitreoretinopathy (FEVR). Bilateral hypoplasia of the optic nerve was found in all three patients by MRI. Genetic analysis showed a known in-frame deletion of the ATOH7 gene in all three patients. This is the first report of a patient with a mutation in the ATOH7 gene that had typical vascular patterns of FEVR in the peripheral retina. The ocular features associated with mutations in the ATOH7 gene overlap those with FEVR at both the early and advanced stages.

Effects of Subcutaneous Methotrexate in Patients with Refractory Uveitis and Chorioretinitis.

Methotrexate (MTX) is an immunosuppressive agent used to treat non-infectious inflammatory eye conditions and is generally administered orally for ocular inflammatory diseases. When used in rheumatological diseases, subcutaneous administration has been reported to show higher efficacy than oral administration. Therefore, this study aimed to evaluate the effect of subcutaneous MTX in patients with refractory uveitis/choroiditis who did not respond to other immunosuppressive agents. A retrospective case-series study was performed between January 2018 and December 2018. Patients with uveitis or chorioretinitis who showed little to no treatment response for 6 months or more with conventional immunosuppressive agents were treated with MTX, administered subcutaneously. After 6 months of treatment, patients were evaluated to determine whether complete suppression of inflammation sustained for ≥28 days was achieved in both eyes and whether improvement can be confirmed by fluorescein angiography (FAG). Subcutaneous MTX treatment was performed on 18 patients, 11 of whom had intermediate uveitis, 7 had posterior uveitis. In the intermediate uveitis patient group, five patients (50% of the group excluding one patient who dropped out) showed improvement in FAG and three patients (30%) showed complete suppression of inflammation. In the posterior uveitis group, two out of seven patients (excluding two patients who dropped out) showed an improvement, two patients in the group showed little change, and one patient showed aggravation of FAG findings. The study confirmed that in patients with uveitis or chorioretinitis who had a refractory response to treatment with other immunosuppressive agents, subcutaneous MTX showed improved treatment efficacy.

Bartonella henselae-Associated Optic Neuropathy Presenting as a Central Scotoma in the Absence of Overt Papillitis - A Multimodal Imaging Study.

To describe the use of multimodal imaging to establish the diagnosis of Bartonella henselae-associated optic neuropathy in a patient who presented with a central scotoma without overt evidence of optic nerve involvement. Case report. Main outcome measures included clinical, optical coherence tomography, and fluorescein angiography findings. A 72-year-old woman presented with a three-day history of central scotoma in the left eye. Her examination was remarkable for faint exudation in the nasal macula of the left eye, but was otherwise normal for her age. Spectral domain optical coherence tomography of the macula revealed mild thickening of the papillomacular bundle with scattered small cystoid spaces and several intraretinal exudates, none of which were visible clinically. Fluorescein angiography revealed localized leakage of the inferotemporal optic disc. When prompted, the patient recalled being scratched multiple times by her two pet kittens. Serial testing showed rising anti-Bartonella henselae (B. henselae) IgG antibody titers to 1:1280, confirming the suspected diagnosis of B. henselae-associated optic neuropathy. and importance: Bartonella-associated optic nerve involvement can occur without overt evidence of optic disc swelling. Multimodal imaging can be used to suggest the diagnosis and support appropriate serologic testing.

Multimodal Retinal Imaging Findings in Hardikar Syndrome.

To describe the syndromic, clinical, and retinal findings of a patient with an extremely-rare genetic condition known as Hardikar Syndrome (HS) with presentation of optical coherence tomography (OCT), fundus autofluorescence (FAF), fluorescein angiographic (FA), and indocyanine green angiographic (ICG) findings. Clinical course was detailed and followed over time with examinations and multimodal imaging. A 17-year-old patient with HS was referred for possible retinitis pigmentosa. Dilated fundoscopic examination revealed large, multifocal cauliform patches of chorioretinal retinal pigment epithelium (RPE) changes with RPE drop-out involving the macula and periphery in both eyes. Additionally, an inactive choroidal neovascular membrane (CNVM) was present in the left eye. Multimodal imaging with OCT, FAF, FA and ICG correlated with the clinical findings of focal patches of chorioretinal degeneration in both eyes. Additionally, an anomalous finding of the superior retinal arterial vessels filling in tandem with the choroidal was present in the left eye. The patient's clinical findings were consistent with HS, and genetic testing with whole exome sequencing revealed a pathogenic mutation in the MED12 gene, confirming diagnosis. HS is associated with RPE degeneration, creating focal patches of pigmentary chorioretinal atrophic lesions. Vision loss can occur due to the development of CNVMs. We recommend close evaluation and follow-up for HS patients with multimodal retinal imaging.

Combined central serous chorioretinopathy, hypermetropia, short axial length, chorioretinal folds, enlarged/thickened ocular coats, with varying association of scleral changes (CHAFES)

PurposeTo describe a condition with the following features: chronic central serous chorioretinopathy (CCSC), chorioretinal folds, scleral changes (including any of the following flattened or ‘squared off’ posterior pole, ‘T sign’, or thickened ocular coats), accompanied by a short axial length and hypermetropia in a series of 7 patients.MethodsThe case notes of 7 patients presenting with a combination of CSC, choroidal folds scleral changes and hypermetropia were reviewed as part of a retrospective case series. Corrected visual acuities, serial refraction, colour imaging, fluorescein and indocyanine green angiography findings, together with B-ultrasound scan features were recorded, with axial length measurements as available (< 23.3 mm was defined as short).ResultsThe study included 14 eyes of 7 subjects (2 females and 5 males) with a primary presentation of central vision disturbance. All patients showed signs of previous or current episodes of the following features in at least one eye: CSC (5/7 bilateral); choroidal folds (6/7 bilateral), thickening of ocular coats in the 5 in whom this was measured, at least one scleral abnormality on ultrasound in at least one eye. A short axial length at final appointment was recorded in 13/14 eyes.Conclusions and relevanceThe combination of CCSC with choroidal folds, hypermetropia with apparent shortening of the eyeball associated with one or more scleral abnormalities such as a flattened or ‘squared off ‘appearance of the B ultrasound may be a specific ocular condition. The aetiology of this particular combination of posterior segment manifestations is unknown; the choroid could be the primary focus of disease with secondary involvement of the sclera. Alternatively, the features observed may result from a chronic inflammatory process affecting the sclera with secondary effects on the choroid, retinal pigment epithelium and retina. In our case series, the final vision was not significantly different from vision at presentation.

Clinical characteristics of intermediate uveitis in adults according to criteria of the SUN working group.

To analyse the clinical characteristics of adult patients with pars planitis (PP-IU), non-pars planitis (NPP-IU) and multiple sclerosis-associated intermediate uveitis (MS-IU) and distinguish between groups. Seventy-three adult patients with intermediate uveitis (IU) reviewed retrospectively and divided as PP-IU, NPP-IU and MS-IU according to 'The standardization of uveitis nomenclature working group classification criteria.' Demographic and clinical characteristics, OCT and fluorescein angiography (FA) findings, complications and treatments were recorded. A total of 134 eyes of 73 patients were included, and 42 of the patients were classified as PP-IU, 12 as NPP-IU, and 19 as MS-IU. If a patient presenting with blurred vision, or tent-shaped vitreous band/snowballs/snowbank on examination, or vascular leakage on FA and accompanying neurological symptoms, the frequency of demyelinating plaque detection on cranial MRI and the risk of MS-IU increased. Mean BCVA was increased from 0.22 ± 0.30 logMAR to 0.19 ± 0.31 logMAR (p = 0.021). Gender, initial BCVA, snowbank formation, disc oedema and periphlebitis on examination, and disc leakage/occlusion on FA were found predictive of decreased BCVA at final visit (p < 0.05). The clinical features of these three groups are similar, some features that can guide the differential diagnosis. It may be recommended to periodically evaluate "suspicious" patients with MRI for MS.

High Resolution Spectral Domain Optical Coherence Tomography of Multiple Evanescent White Dot Syndrome.

To evaluate a patient with multiple evanescent white dot syndrome (MEWDS) with multimodal imaging including high resolution spectral domain optical coherence tomography (SD-OCT). The patient was evaluated with wide-field color and autofluorescence imaging, microperimetry, and near infrared imaging. SD-OCT was performed using an instrument capable of 3 µm axial resolution, the High-Resolution Heidelberg Spectralis. 28 year-old woman developed photopsias and a scotoma in the field of vision of her left eye. She had multiple whitish spots with granularity in her fovea consistent with the diagnosis of MEWDS. She had supportive fluorescein angiographic and autofluorescence findings. Because of the high resolution and the good layer contrast, it was possible to create en face slab images of the external limiting membrane (ELM), the ellipsoid zone (EZ), interdigitation zone (IZ), and the retinal pigment epithelium (RPE). The ELM showed no abnormalities. There were multiple regions of decreased reflectance in the EZ slab, but even more prominent changes in the IZ. The RPE showed nearly no variation in layer reflectivity. With resolution of symptoms, the color and autofluorescence images returned to normal, the defects in the EZ almost completely resolved and the IZ continued to show abnormalities. Although past studies concluded the EZ was the main region of involvement in MEWDS, high resolution SD-OCT suggests the IZ was more prominently affected in this case.

Widefield Fluorescein Angiography Findings in Pediatric Patients with X-Linked Retinoschisis

To evaluate the retinal vasculature in pediatric patients with X-linked retinoschisis (XLRS). Retrospective consecutive case series. Pediatric patients with a diagnosis of XLRS who had undergone widefield fluorescein angiography (FA). The electronic medical records of pediatric patients with XLRS at a tertiary referral eye center were reviewed from January 2015 to December 2021. Fluorescein angiography images were reviewed for anomalies of the retinal vasculature. Vascular anomalies on FA were recorded, including capillary dropout/ischemia, terminal supernumerary vessels, vascular leakage, abnormal vascular loops, straightening of vessels, aberrant circumferential vessels, and neovascularization. In total, 29 eyes of 15 patients were included in the study (1 patient had a phthisical eye). On FA, the most common findings were capillary dropout/ischemia (21 of 29 eyes, 72.4%), terminal supernumerary vessels (21 eyes, 72.4%), abnormal vascular loops (20 eyes, 69%), and vascular leakage (17 eyes, 58.6%). Of the 17 eyes with leakage, the most posterior zone of involvement was zone 1 in 11 eyes (64.7%) and zone 2 in 6 eyes (35.3%). All eyes demonstrated ≥ 1 vascular anomaly on FA. Among the 29 eyes, 23 (79.3%) demonstrated peripheral bullous schisis or retinal detachment (RD) with a mean of 5.6 clock hours of involvement. The presence of either RD or bullous retinal schisis was associated with the incidence of capillary dropout (91.3% in schisis/RD eyes vs. 0% in nonschisis/RD eyes, P < 0.001). Among those with RD or bullous schisis, a higher degree of involvement correlated with more severe capillary dropout (Pearson 0.49, P=0.025). The present study demonstrates consistent vascular changes in pediatric patients with XLRS using widefield FA. Although the presence of capillary ischemia was associated with the severity of bullous schisis or RD, other vascular anomalies were observed in patients both with and without peripheral schisis. Although further research is needed to understand the etiology of these vascular anomalies, FA should be considered in the evaluation of these patients.

Sympathetic Ophthalmia: Demographic Characteristics, Clinical Findings, and Treatment Results.

To evaluate the demographic characteristics, clinical findings, and treatment approach of patients with sympathetic ophthalmia (SO). The records of 14 patients with SO between 2000 and 2020 were retrospectively reviewed. The patients' Snellen best corrected visual acuity (BCVA), detailed ophthalmological examination, optical coherence tomography (OCT), enhanced depth imaging-OCT (EDI-OCT), fundus fluorescein angiography findings, and treatment approaches were recorded. The study included the 14 sympathizing eyes of 14 patients with SO (7 female, 7 male). The mean age was 48.5±15.4 years (range: 28-75), and the mean follow-up duration was 55.1±48.7 months (range: 6-204). Ten patients (71%) had a history of ocular trauma and 4 (29%) had a history of ocular surgery. The time to symptom onset in the sympathizing eye after trauma or ocular surgery ranged from 15 days to 60 years. The most common posterior segment findings were optic disc edema (36%) and exudative retinal detachment (36%). In the acute period, the mean choroidal thickness value on EDI-OCT was 716.5±63.6 μm (range: 635-772) and decreased to 296±81.6 μm (range: 240-415) after treatment. Treatment with high-dose systemic corticosteroid was given to 8 patients (57%), azathioprine (AZA) to 7 (50%), AZA and cyclosporine-A combination to 7 (50%), and tumor necrosis factor-alpha inhibitors to 3 patients (21%). Recurrence was observed in 4 patients (29%) during follow-up. At last follow-up, BCVA values were better than 20/50 in 11 (79%) of the sympathizing eyes. Remission was achieved in 13 patients (93%), but 1 patient (7%) lost her vision due to acute retinal necrosis. SO is a bilateral inflammatory disease that presents with granulomatous panuveitis after ocular trauma or surgery. Favorable functional and anatomical results can be obtained with early diagnosis and initiation of appropriate treatment.

Ophthalmic Manifestations of ROSAH (Retinal Dystrophy, Optic Nerve Edema, Splenomegaly, Anhidrosis, and Headache) Syndrome, an Inherited NF κB–Mediated Autoinflammatory Disease with Retinal Dystrophy

We aimed to characterize the ocular phenotype of patients with ROSAH (retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and headache) syndrome and their response to therapy. Single-center observational case study. Eleven patients with a diagnosis of ROSAH syndrome and mutation in ALPK1 were included. Patients with molecularly confirmed ROSAH syndrome underwent ophthalmic evaluation, including visual acuity testing, slit-lamp and dilated examinations, color fundus and autofluorescence imaging, fluorescein angiography, OCT, and electrophysiologic testing. Visual acuity, electrophysiology, fluorescein angiography, and OCT findings. Eleven individuals (6 female and 5 male patients) from 7 families ranging in age from 7.3 to 60.2 years at the time of the initial evaluation were included in this study. Seven patients were followed up for a mean of 2.6 years (range, 0.33-5.0 years). Best-corrected visual acuity at baseline ranged from 20/16 to no light perception. Variable signs or sequelae of intraocular inflammation were observed in 9 patients, including keratic precipitates, band keratopathy, trace to 2+ anterior chamber cells, cystoid macular edema, and retinal vasculitis on fluorescein angiography. Ten patients were observed to show optic disc elevation and demonstrated peripapillary thickening on OCT. Seven patients showed retinal degeneration consistent with a cone-rod dystrophy, with atrophy tending to involve the posterior pole and extending peripherally. One patient with normal electroretinography findings and visual evoked potential was found to have decreased Arden ratio on electro-oculography. Leveraging insights from the largest single-center ROSAH cohort described to date, this study identified 3 main factors as contributing to changes in visual function of patients with ROSAH syndrome: optic nerve involvement; intraocular inflammation, including cystoid macular edema; and retinal degeneration. More work is needed to determine how to arrest the progressive vision loss associated with ROSAH syndrome. Proprietary or commercial disclosure may be found after the references.

Ischemia and laser photocoagulation in retinal vein occlusion

Retinal vein occlusions (RVO) are associated with retinal ischemia to ahighly variable extent. An ischemic retina may lead to the development of neovascularization and further to secondary complications such as neovascular glaucoma, vitreous hemorrhage or tractional retinal detachment. Numerous factors such as vascular endothelial growth factor (VEGF) and other cytokines are produced in the ischemic area, which cause macular edema. Before the introduction of intravitreal drug injections (IVI), retinal laser photocoagulation was the leading form of treatment. Macular laser photocoagulation was applied in the form of focal laser or grid laser in patients with branch retinal vein occlusion (BRVO) to treat macular edema. In patients with ischemic RVO, panretinal laser photocoagulation (PRP) was recommended for treatment of secondary neovascular complications. The value of laser treatment in the management of patients with RVO changed after the introduction of IVI treatment. This article presents a review of the current study results and the recommendations for performing laser photocoagulation of the central and peripheral retina in patients with RVO. Conventional focal or grid laser photocoagulation has been replaced by IVI treatment in the management of macular edema secondary to BRVO; however, macular laser treatment can still be considered in patients with BRVO if the macular edema persists despite the use of available IVI drugs. The use of central laser photocoagulation in these cases is based on the findings of fluorescein angiography. Disseminated panretinal laser photocoagulation is still indicated in RVO patients who have large areas of nonperfusion, have developed neovascularization and/or late complications. Targeted laser photocoagulation of the peripheral areas of nonperfusion has recently been recommended by several authors and is expected to improve not only the visual outcome of IVI treatment, but more importantly to also reduce the duration of treatment and the number of re-injections needed. Clear evidence for targeted laser treatment is not yet available and is afocus of currently ongoing prospective randomized studies.

Filler-induced blindness “seen” by ophthalmologists: Case presentation and treatment algorithm

Filler-induced blindness (FIB) is the most threatening complication following periocular injection. To date, no standard of care has been established. The goal of this study is to report a new case of FIB with partial visual recovery and present our personalized algorithm for treatment based on fluorescein angiography findings. Case report with 24 months follow-up and treatment algorithm. Our patient experienced complete vision loss to no light perception following forehead lipofilling. Retinal angiography identified a posterior ciliary artery occlusion. Antiplatelet medication, steroids and intraocular pressure lowering medications were administrated, followed by hyperbaric oxygen treatment (HBOT). Visual acuity improved to +0.8 logMar. The HBOT treatment was monitored by fluorescein angiogram. Based on this case and on the ophthalmic literature on retinal and ciliary artery occlusion, we established a personalized FIB protocol guided by fluorescein angiography. Although prevention remains the best treatment, all physicians should be prepared to manage FIB. Prompt management at the office guided by written protocols, as well as emergency kits, are essential. In referral centers, personalized treatment should be undertaken based on fluorescein angiography findings.

Fluorescein Angiography Findings in Treatment-Naive Premature Infants with Retinal Vascular Immaturity and Persistent Avascular Retina

ABSTRACTPurposeTo evaluate the fluorescein angiography (FA) findings in eyes with spontaneously regressed retinopathy of prematurity (ROP).MethodsFluorescein angiography images of 162 eyes of 81 treatment-naive infants who underwent FA due to retinal vascular immaturity and persistent avascular retina (PAR) despite exceeding postmenstrual age of 60 weeks were analyzed retrospectively. Disc diameter (DD), optic disc-to-fovea distance (FD), the length of temporal retinal vascularization (LTRV), and the length of measurable temporal avascular retina distance (LMTAR), were quantitatively measured.ResultsThe mean gestational age and FA imaging age were 29.39 ± 3.13 and 86.51 ± 24.80 weeks postmenstrual, respectively. The mean ratios of LTRV/FD and LMTAR /DD were 4.47 ± 0.36 and 2.21 ± 1.01, respectively. Pigmentary changes were detected in the peripheral retina in 21% of the eyes. There was at least one angiographic finding in 88% of the eyes, but these findings were usually mild. Based on the FA findings, laser photocoagulation was performed to the peripheral avascular retina in ten eyes of five patientsConclusionEven in larger preterm infants and without severe retinopathy and anti-VEGF treatment, PAR and peripheral pigmentary changes may be detected, and mild angiographic vascular activity may continue. These findings may lead to late-onset retinal pathologies that may threaten vision. In eyes with PAR, follow-up with FA and prophylactic laser application may be applicable. Further investigation is required for this topic.

Wide-field Fundus Imaging and Fluorescein Angiography Findings in Various Pseudoretinoblastoma Conditions.

To report wide-field fundus imaging and fluorescein angiography findings in conditions mimicking retinoblastoma (pseudoretinoblastoma). The clinical and imaging records of 28 patients (36 eyes) imaged with RetCam 3 (Clarity Medical Systems, Inc) wide-field fundus photography and fluorescein angiography who were diagnosed as having various pseudoretinoblastoma disorders between February 2020 and August 2021 were retrospectively evaluated. Most patients were referred with suspicion of retinoblastoma. Other patients had unresolved eye conditions and received initial treatment elsewhere and they were referred later for exclusion of retinoblastoma. On RetCam fundus photography and fluorescein angiography, pseudoretinoblastoma conditions were diagnosed as Coats disease (9 eyes), congenital glaucoma (3 eyes), persistent fetal vasculature (3 eyes), familial exudative vitreoretinopathy (2 eyes), retinopathy of prematurity (2 eyes), myelinated retinal nerve fibers (2 eyes), optic nerve hypoplasia (2 eyes), oculocutaneous albinism (2 eyes), meridional fold (2 eyes), combined hamartoma of retina and retinal pigment epithelium (2 eyes), grouped congenital hypertrophy of the retinal pigment epithelium (1 eye), retinal astrocytic hamartoma (1 eye), morning glory syndrome (1 eye), optic glioma (1 eye), giant choroidal nevus (1 eye), vasculitis (1 eye), and chorioretinitis (1 eye). RetCam imaging and fluorescein angiography demonstrated telangiectasias, microaneurysms, submacular exudation/fibrosis, capillary non-perfusion, and exudation posterior to telangiectasias in Coats disease. Hypofluorescent optic discs, peripheral non-perfusion, and vascular leakage were observed in congenital glaucoma. Large areas of capillary non-perfusion, poor foveal morphology/formation, elongated ciliary processes with hyperfluorescent central core, and hyperfluorescent fibrovascular stalk at the posterior pole were hallmarks of persistent fetal vasculature. RetCam wide-field fundus imaging and fluorescein angiography play an important role in the diagnosis of conditions simulating retinoblastoma. [J Pediatr Ophthalmol Strabismus. 2023;60(1):60-74.].
