Combinative approach of transzonular triamcinolone-moxifloxacin and perioperative drops to minimize postoperative complications of cataract surgery

AIM: To investigate the effectiveness of combination therapy with transzonular triamcinolone-moxifloxacin and conventional perioperative drops in reducing postoperative complications of cataract surgery. METHODS: Electronic medical records of cataract surgery patients (single surgeon) were reviewed from January 2018 to September 2021. The rate of postoperative complications including prolonged and/or recurrent postoperative inflammation, endophthalmitis, cystoid macular edema (CME), and intraocular pressure (IOP) was compared between the patients receiving combinative therapy and patients receiving drops only. RESULTS: Totally 596 patients and 1057 eyes (Combinative-Therapy group 493 and Drop-Only group 564) were included in this study. Using combination therapy reduced the relative risk of postoperative inflammation by 26.9% (16.6% Combinative-Therapy vs 22.7% Drop-Only, P=0.013). The incidence of endophthalmitis was 0 in Combinative-Therapy group vs 0.5% in Drop-Only group (relative risk reduction 100%), although not statistically significant (P=0.10). The incidence of severe IOP spikes was not significantly different between Combinative-Therapy (2.4%) and Drop-Only (1.6%) groups (P=0.33). The relative risk of postoperative CME was 51.4% less in three months follow up visit in Combinative-Therapy group, although not statistically significant (P=0.07). The visual outcome 1-month postop. (best corrected visual acuity) was significantly better in Combinative-Therapy (logMAR 0.10) compared to Drop-Only (logMAR 0.14) groups (P=0.02) while the baseline visual acuity was not significantly different. CONCLUSION: The combinative approach of transzonular triamcinolone-moxifloxacin plus perioperative eyedrops is an effective method to minimize postoperative inflammation, with better visual outcomes. It could potentially reduce the risk of postoperative endophthalmitis and CME (near-significant P-values; larger studies could analyze better considering low incidence).

Visual outcome of cataract surgery in paediatric uveitis

1. To analyse the visual outcome in patients of paediatric uveitis who underwent cataract surgery; 2. To analyse the post-operative complications of cataract surgery in paediatric uveitis.Retrospective observational study was done on patients of uveitis who underwent cataract surgery. Patients who were under 18 years and co-operative for examination were included.They underwent Phacoaspiration with posterior chamber IOL implantation by a single surgeon after 3 months of activity free interval, BCVA(in Log MAR) in every follow up, anterior segment examination using slit lamp and posterior segment examination using IDO, post-operative complications and Intra ocular pressure was recorded using Noncontact tonometer.Uveitis was classified using the SUN classification of uveitis. Use of corticosteroids, biologics and immunosuppressive drug were collected at each visit. Total of 18 subjects diagnosed with cataract as a complication of uveitis & undergone cataract surgery were studied (6 were females, 12 were males) 9 had anterior uveitis, 1had intermediate uveitis and 5 had pan uveitis. JRA (66.7%) was the most common cause identified. Improvement in vision from baseline was observed post-surgery at the end of first, third and 6th month which was statistically significant (P- Value <0.05). Average duration of disease before they underwent surgery was 18 months. Most common post op complication was posterior capsular opacification (50 %), others include secondary glaucoma (38.9), exudative retinal detachment (5.6%) and Vitritis (22.2%)Unlike adult uveitic patients, the surgical management of paediatric uveitic cataract is both challenging and controversial, and the surgery itself has been associated with poor visual outcomes. However, our study had shown that with implantation of IOL, good immunosuppressants and control of the disease can give these children a good visual outcome.

Does addition of intravitreal bevacizumab confer additional benefit in management of proliferative diabetic retinopathy?

To evaluate visual outcome and complications of PDR after treatment with Intravitreal Bevacizumab followed by Pan Retinal Photocoagulation A hospital based retrospective study was done in the Department of Ophthalmology, to evaluate visual outcome and complications of PDR after treatment with intravitreal Bevacizumab followed by Pan Retinal Photocoagulation. Visual Acuity, Dilated fundus examination, OCT macula were done on subsequent follow ups 135 eyes of 133 patients were included in the study.The mean pre procedure visual acuity is 0.639±0.5327 which improved to 0.451±0.4089 post procedure. P value is <0.001 which is statistically significant.i.e, 94 (69.62%) eyes had improved vision, 21(15.55%) had stable vision and 20(14.81%) eyes had decreased vision. After injection followed by PRP out of 135 eyes,4(2.96%) eyes developed vitreous hemorrhage which resolved with repeat intravitreal anti-VEGF injection, 6(4.44%) eyes developed diabetic macular edema,3(2.2%) eyes developed Neovascularisation of iris and 4(2.96%)eyes developed vitreous hemorrhage with traction retinal detachment.From our study it appears that addition of intravitreal anti VEGF to Pan Retinal Photocoagulation for PDR confers the additional benefit of less incidence of vitreous hemorrhage and less incidence of traction retinal detachment requiring surgery in the 1 one year of follow up. This amounts to more compliance by the patient for taking the treatment as well as better visual outcome

Unveiling the retinal secrets of neuromyelitis optica spectrum disorder

BackgroundVascular alterations are now recognized as important contributors to the pathophysiology of neuromyelitis optica spectrum disorder (NMOSD). This study aimed to use optical coherence tomography (OCT) and OCT-angiography (OCTA) to assess alterations in the retinal structure and microvasculature in patients with NMOSD, so we can understand pathophysiology of NMOSD, implicating this on disease activity, visual outcome and management on the future.MethodsA case–control study was conducted on 40 NMOSD patients with (NMOSD + ON) and without (NMOSD – ON) history of optic neuritis and 36 healthy subjects. The following data were assessed in NMOSD patients: clinical history, EDSS, and visual function testing. Both groups underwent spectral domain (SD)-OCT and OCTA.ResultsIn this study, NMOSD + ON patients had a statistically significant reduction in all SD-OCT parameters compared to healthy control. Regarding OCTA, there was a significant reduction in radial peripapillary capillary density (RPCD) in NMOSD + ON (P-value < 0.001) and some sectors of NMOSD–ON compared to healthy control. NMOSD + ON patients had significant differences in RPCD compared to those without (P-value < 0.001).ConclusionsHere we show that the advance of this study is that retinal microvascular alterations have been noticed in NMOSD–ON eyes, indicating that subclinical primary retinal vasculopathy and disease activity may occur in NMOSD before onset of ON and retinal atrophy. This may have implications on early detection of disease activity, early interference in management and prognostic tool to visual outcome in following the patients.

Factors affecting anatomical and visual outcomes in Terson syndrome managed by surgery or observation.

To investigate visual outcomes and prognostic factors of patients with Terson syndrome (TS) managed with observation or pars plana vitrectomy (PPV). retrospective review of medical records of 117 eyes from 81 patients (43 females) with TS. Main outcome measures were final best corrected visual acuity (BCVA), intraoperative findings and long-term sequelae. 46 (39.3%) eyes were managed conservatively and 71 (60.7%) eyes underwent PPV. Median follow-up was 8.4 months. The PPV group had significantly worse (p < 0.001) baseline BCVA (median 2.3 versus 0.7 logMAR, Snellen equivalent 20/4000 versus 20/100). Final BCVA did not differ between the two groups (p = 0.38). Final BCVA ≥ 0.3 logMAR (20/40) in the surgery group was associated with post-operative retinal detachment (p = 0.013) and macular abnormalities (p = 0.014), and in the observation group with ocular comorbidity (p = 0.008). Retinal breaks were detected intraoperatively in 25 (35.2%) eyes and were associated with an interval longer than 3 months between ocular diagnosis and surgery (p = 0.04), but not with larger gauge instrumentation and posterior vitreous detachment. Incidence of ERM did not differ among patients managed conservatively and after PPV (p = 0.9) and between eyes undergoing early or delayed surgery (p = 0.09). The most common post-operative complications were cataract in 16 (22.5%) eyes and ERM in 8 (11.3%) eyes. visual outcomes in TS are similar with both management strategies. Surgery allows faster and greater visual recovery but carries high risk of intraoperative retinal tears if delayed for longer than 3 months from initial presentation. ERM and retinal detachment are not correlated with timing of surgery or management strategy.

Clinical outcomes of the light adjustable lens in eyes with a history of prior corneal refractive surgery.

This study aimed to evaluate the visual and refractive outcomes in eyes with a history of laser corneal refractive surgery implanted with the second-generation light-adjustable lens (LAL). Private Practice, Sioux Falls, South Dakota, US. Retrospective, consecutive case series. Eyes with a history of prior corneal refractive surgery that underwent cataract surgery with implantation of the LAL and were targeted for plano were included. Data on the type and number of prior refractive surgeries were collected, in addition to the timing and number of postoperative adjustments. The primary outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and the percentage (%) of eyes within ±0.25 diopter (D), ±0.50D, and ±1.00 D of their refractive target. 76 eyes from 70 patients were included. A total of 45 eyes with a history of one prior refractive surgery and 31 eyes with a history of ≥2 refractive surgeries were included. 74% (n=56) of all eyes achieved UDVA of 20/20 or better, 88% (n=67) achieved 20/25 UDVA or better and 93% (n=71) were correctable to 20/20 or better postoperatively. For refractive outcomes, 66% of eyes (n=50) were within ±0.25 D and 86% (n=65) were within ±0.50 D of refractive target. Patients with a history of laser corneal refractive surgery achieved favorable visual and refractive outcomes with the LAL. This intraocular lens (IOL), which affords postoperative adjustability, is a promising option for patients with a history of corneal refractive surgery who maintain high expectations for functional uncorrected acuity following cataract surgery.

Long-term prognosis of acute primary angle closure in an east asian cohort.

To provide an updated analysis of the long-term outcomes of patients with acute primary angle closure (APAC) and to investigate the risk factors for visual field (VF) loss progression. Retrospective, clinical cohort study METHODS: One hundred and forty-six APAC patients with a minimum of 1-year follow-up were included. The presenting features and the treatment utilized were recorded. The visual and intraocular pressure (IOP) outcomes were analyzed. The main outcome measures were the proportion of blindness and IOP at the final visit. A subset of patients with sufficient VF results was divided into a stable and progressive group based on mean deviation (MD) loss rate. Univariate and multivariate logistic regression analyses were performed to identify predictors of progression. Nine patients (6.2%) were blind, and 76.0% (111/146) had final decimal visual acuity greater than or equal to 0.5. All patients had normal final IOP, and 65.1% (95/146) were medication-free. 64.4% (94/146) underwent cataract surgery at a median 4months after their APAC attack. The use of topical hypotensive medications (OR = 8.029, P = 0.012) was the only significant predictor of fast MD loss in the multivariate regression. The long-term outcomes of APAC in recent years have been more promising. All patients maintained normal IOP several years following their APAC attack, and fewer than half required hypotensive agents. The incidence of blindness was low. These findings suggest that current practice patterns in the management of APAC are beneficial.

Childhood-Onset Non-Infectious Uveitis in the “Biologic Era”. Results From Spanish Multicenter Multidisciplinary Real-World Clinical Settings

ABSTRACT Objective To characterize and describe clinical experience with childhood-onset non-infectious uveitis. Study Design A multicenter retrospective multidisciplinary national web-based registry of 507 patients from 21 hospitals was analyzed. Cases were grouped as immune disease-associated (IMDu), idiopathic (IDIu) or ophthalmologically distinct. Characteristics of juvenile idiopathic arthritis-associated (non-HLA-B27-related) uveitis (JIAu), IDIu, and pars planitis (PP) were compared. Results IMDu (62.3%) and JIAu (51.9%) predominated in young females; and IDIu (22.7%) and PP (13.6%) in older children, without sex imbalance. Ocular complications occurred in 45.3% of cases (posterior synechiae [28%], cataracts [16%], band keratopathy [14%], ocular hypertension [11%] and cystoid macular edema [10%]) and were associated with synthetic (86%) and biologic (65%) disease-modifying antirheumatic drug (DMARD) use. Subgroups were significantly associated (p < 0.05) with different characteristics. JIAu was typically anterior (98%), insidious (75%), in ANA-positive (69%), young females (82%) with fewer complications (31%), better visual outcomes, and later use of uveitis-effective biologics. In contrast, IDIu was characteristically anterior (87%) or panuveitic (12.1%), with acute onset (60%) and more complications at onset (59%: synechiae [31%] and cataracts [9.6%]) and less DMARD use, while PP is intermediate, and was mostly bilateral (72.5%), persistent (86.5%) and chronic (86.8%), with more complications (70%; mainly posterior segment and cataracts at last visit), impaired visual acuity at onset, and greater systemic (81.2%), subtenon (29.1%) and intravitreal (10.1%) steroid use. Conclusion Prognosis of childhood uveitis has improved in the “biologic era,” particularly in JIAu. Early referral and DMARD therapy may reduce steroid use and improve outcomes, especially in PP and IDIu.

Quantitative Microvascular Change Analysis Using a Semi-Automated Software in Macula-off Rhegmatogenous Retinal Detachment Assessed by Swept-Source Optical Coherence Tomography Angiography

Objective: To analyze the performance of custom semi-automated software for quantitative analysis of retinal capillaries in eyes with macula-off rhegmatogenous retinal detachment (RRD) and the role of these microvascular measures as potential biomarkers of postoperative visual outcomes. Methods: A prospective, observational, and single-center study was conducted on consecutive patients who underwent 25G pars-plana vitrectomy for primary uncomplicated macula-off RRD. Optical coherence tomography angiography (OCTA) was performed in the fellow and RRD eyes before surgery and in months 1, 3, and 6 after surgery. The preoperative values of the fellow eyes were used as surrogates of macula-off ones. The primary endpoints were the mean vessel diameter index (VDI); vessel area density (VAD); and vessel skeleton density (VSD) at month 6. Results: Forty-four eyes (44 patients) were included in the study. Considering the fellow eyes as a surrogate of preoperative values of macula-off eyes, VDI in superficial (SCP) and deep (DCP) capillary plexuses was significantly reduced at month 6 (p = 0.0087 and p = 0.0402, respectively); whereas VSD in SCP increased significantly from preoperative values (p = 0.0278). OCTA built-in software parameters were significantly reduced from month 1 to month 6 in both SCP and DCP (p values ranged between 0.0235 and &lt;0.0001). At month 6, 25 (56.8%) eyes achieved a best-corrected visual acuity BCVA ≥ 0.3 (LogMAR). The greater the preoperative BCVA, the greater the probability of achieving good visual outcomes (Odds ratio: 11.06; p = 0.0037). However, none of the OCTA parameters were associated with the probability of achieving a BCVA improvement ≥ 0.3. Conclusions: Quantitative evaluation of capillary density and morphology through OCTA and semi-automated software represents a valuable tool for clinical assessment and managing the disease comprehensively.

Visual Results Following Surgery for Unilateral Congenital Cataract at a Tertiary Public Hospital in Maharashtra

Purpose: This study aimed to assess the visual outcomes of unilateral congenital cataract surgery in children.  Methods: A total of 204 eyes from 204 children, aged 2 to 12 months, undergoing unilateral congenital cataract surgery between December 2022 and March 2024, were included. The study analyzed data from a three-year follow-up and used chi-square tests to assess the relationship between visual outcomes and the age at surgery, considering P &lt; 0.05 as statistically significant.  Results: Of 204 eyes, 64 (31.4%) underwent surgery at 2-3 months and 140 (68.6%) at 3-12 months. Visual acuity was measured postoperatively, revealing significantly poorer outcomes in children aged 3 months or older (P &lt; 0.001) compared to those aged 2-3 months.  Conclusions: It is essential to detect and treat congenital cataracts early, followed by long-term postoperative rehabilitation, to improve visual outcomes in affected children, particularly in cases of unilateral cataract, which are more prone to developing amblyopia.

Visual Deficits and Diagnostic and Therapeutic Strategies for Neurofibromatosis Type 1: Bridging Science and Patient-Centered Care

Neurofibromatosis type 1 (NF1) is an inherited autosomal dominant disorder primarily affecting children and adolescents characterized by multisystemic clinical manifestations. Mutations in neurofibromin, the protein encoded by the Nf1 tumor suppressor gene, result in dysregulation of the RAS/MAPK pathway leading to uncontrolled cell growth and migration. Neurofibromin is highly expressed in several cell lineages including melanocytes, glial cells, neurons, and Schwann cells. Individuals with NF1 possess a genetic predisposition to central nervous system neoplasms, particularly gliomas affecting the visual pathway, known as optic pathway gliomas (OPGs). While OPGs are typically asymptomatic and benign, they can induce visual impairment in some patients. This review provides insight into the spectrum and visual outcomes of NF1, current diagnostic techniques and therapeutic interventions, and explores the influence of NF1-OPGS on visual abnormalities. We focus on recent advancements in preclinical animal models to elucidate the underlying mechanisms of NF1 pathology and therapies targeting NF1-OPGs. Overall, our review highlights the involvement of retinal ganglion cell dysfunction and degeneration in NF1 disease, and the need for further research to transform scientific laboratory discoveries to improved patient outcomes.

Bioavailability of Lutein from Marigold Flowers (Free vs. Ester Forms): A Randomised Cross-Over Study to Assess Serum Response and Visual Contrast Threshold in Adults

Lutein (Lut) and zeaxanthin (Zeax) are found in the blood and are deposited in the retina (macular pigment). Both are found in the diet in free form and esterified with fatty acids. A high intake and/or status is associated with a lower risk of chronic diseases, especially eye diseases. There is a large global demand for Lut in the dietary supplement market, with marigold flowers being the main source, mainly as lutein esters. As the bioavailability of Lut from free or ester forms is controversial, our aim was to assess the bioavailability of Lut (free vs. ester) and visual contrast threshold (CT). Twenty-four healthy subjects (twelve women, twelve men), aged 20–35 and 50–65 years, were enrolled in a cross-sectional study to consume 6 mg lutein/day from marigold extract (free vs. ester) for two months. Blood samples were taken at baseline and after 15, 40, and 60 days in each period. Serum Lut and Zeax were analysed using HPLC, and dietary intake was determined with a 7-day food record at the beginning of each period. CT, with and without glare, was at 0 and 60 days at three levels of visual angle. Lut + Zeax intake at baseline was 1.9 mg/day, and serum lutein was 0.36 µmol/L. Serum lutein increased 2.4-fold on day 15 (up to 0.81 and 0.90 µmol/L with free and ester lutein, respectively) and was maintained until the end of the study. Serum Zeax increased 1.7-fold. There were no differences in serum Lut responses to free or ester lutein at any time point. CT responses to lutein supplementation (free vs. ester) were not different at any time point. CT correlated with Lut under glare conditions, and better correlations were obtained at low frequencies in the whole group due to the older group. The highest correlations occurred between CT at high frequency and with glare with serum Lut and Lut + Zeax. Only in the older group were inverse correlations found at baseline at a high frequency with L + Z and with Lut/cholesterol and at a low frequency with Lut/cholesterol. In conclusion, daily supplementation with Lut for 15 days significantly increases serum Lut in normolipemic adults to levels associated with a reduced risk of age-related eye disease regardless of the chemical form of lutein supplied. Longer supplementation, up to two months, does not significantly alter the concentration achieved but may contribute to an increase in macular pigment (a long-term marker of lutein status) and thus improve the effect on visual outcomes.

VISUAL OUTCOME FOLLOWING PARS PLANA VITRECTOMY IN POST-OPERATIVE ENDOPHTHALMITIS PATIENTS

Postoperative endophthalmitis is a serious complication following ocular surgery that can lead to significant visual impairment. Pars plana vitrectomy (PPV) is one of the treatment options for managing this condition, but its visual outcomes are not well-established. Objective: This study aimed to assess the visual outcome following pars plana vitrectomy in patients with postoperative endophthalmitis. Methods: This interventional study was conducted at the eye ward of Hayatabad Medical Complex, Peshawar, from September 2023 to February 2024. Forty patients with postoperative endophthalmitis underwent pars plana vitrectomy. Visual acuity was evaluated in the 12th week after the procedure. Results: Among the patients evaluated, 15% demonstrated a visual acuity improvement of 6/18 or higher, while 22.5% showed an improvement of 6/60 or better. Additionally, 35% of patients could count fingers, 17.5% had vision of hand movement, and 10% showed no increase in visual acuity. There was no significant relationship between age distribution and post-follow-up improvement in visual acuity. Conclusion: Pars plana vitrectomy in patients with postoperative endophthalmitis can lead to positive outcomes in terms of improved visual acuity.

Long-term Visual Outcomes and OCT Biomarkers in Eyes with Macular Edema Secondary to Retinal Vein Occlusion following Anti-VEGF Therapy

Purpose: To evaluate the structural characteristics and long-term visual outcomes in eyes impacted by macular edema as a consequence of retinal vein occlusion (RVO) that have undergone effective treatment with anti-vascular endothelial growth factor (VEGF) therapy. Methods: Inclusion criteria comprised 42 eyes of 41 patients, subjected to long-term follow-up, displaying resolved macular edema after a minimum of 5 years since the commencement of anti-VEGF therapy. During the final visit, two experienced observers evaluated several qualitative parameters using spectral-domain optical coherence tomography (SD-OCT), such as the integrity of the external limiting membrane (ELM), the state of the ellipsoid zone (EZ) and retinal pigment epithelium (RPE), and the presence of retinal inner layer disorganization (DRIL). Additionally, a quantitative evaluation of the inner and outer retinal thicknesses was conducted for the purpose of topographical analysis. Results: The most prominent qualitative correlation identified with best-corrected visual acuity (BCVA) during the final visit was connected to the presence of DRIL (P=0.004) and the integrity of the ELM (P=0.015). In relation to quantitative aspects, a noteworthy correlation was noted between the visual acuity during the last visit and the parafoveal thickness in both the inner (P=0.003) and outer retina (P=0.018). Conclusions: In eyes where macular edema resulting from RVO has been successfully resolved with anti-VEGF therapy, changes in the status of the ELM and the presence of DRIL serve as valuable OCT biomarkers, indicating prolonged visual outcomes.

Impact of treat and extend criteria on proportions that can be extended after loading phase of 2 mg aflibercept therapy for neovascular age related macular degeneration: PRECISE Report 5.

To study the impact of definitions of various treatment extension criteria on the proportion of patients who could be extended at their first visit after the loading phase of 2 mg aflibercept therapy for neovascular age related macular degeneration (nAMD). Patients with nAMD initiated on the loading phase of three intravitreal doses of 2 mg aflibercept in routine clinical practice were recruited from December 2019 to August 2021. The response to the loading phase was assessed at approximately 8 weeks post-loading (up to 140 days from first injection) based on different definitions of response. The proportion of patients that qualify for interval extension based on different clinical trial criteria was also evaluated. A total of 722 patients with visual acuity (VA) and optical coherence tomography (OCT) scans done at all 4 visits were included. Of these 32.4% of eyes responded with complete macular fluid resolution after the first injection with no recurrence through the loading phase (super-responders) while 26.9% had persistent macular fluid in all 4 visits (true non-responders). The rest were considered suboptimal responders. Change in VA showed marked variations within each of these categories of fluid resolution. For extension of next treatment interval, if presence of any macular fluid at the post-loading visit is the only criteria considered, about 50% could be extended to 8 weeks. If both VA worsening by ≥5 letters and a > 25 μm increase in central sub-field thickness (CST)are considered, 90% will be eligible for interval extension. Clinical trial designs and pre-defined treatment extension/shortening criteria determine the proportion of patients requiring treatment in the post-loading visit. The short and long-term impact of interval extension immediate post-loading on visual outcome in clinical practice is unknown.

Paediatric non-infectious granulomatous uveitis: a retrospective cohort study.

Paediatric granulomatous uveitis (PGU) is rare. In addition, lack of awareness often leads to delayed diagnosis and poor visual outcome. Identifying the underlying cause and deciding how best to treat each patient is challenging. To evaluate the demographics, aetiologies, complications, treatments, and visual prognosis of paediatric non-infectious granulomatous uveitis. Retrospective chart review of non-infectious PGU occurring in children before the age of 16 years recruited from the Paediatric Rheumatology Unit, Bicêtre Hospital, France, from 2001 to 2023. We included 50 patients with 90 affected eyes: 29 with idiopathic uveitis, 15 with sarcoidosis, 5 with juvenile idiopathic arthritis, and one with Vogt-Koyanagi-Harada disease. Median age at diagnosis was 9.8 years (range 7.2-12.5). The sex-ratio M/F was 0.52. The most common features of PGU were: panuveitis (56%), bilateral (84%), and chronic (84%). Sarcoidosis was the most frequent diagnosis after idiopathic disease, particularly in the presence of lymphopenia and hypergammaglobulinemia. Uveomeningitis was present in 12% of cases. Upon diagnosis, ocular complications were present in 68 of 90 eyes (76%) particularly in cases of panuveitis. The most commonly used treatments were systemic corticosteroids (72%) and methotrexate (80%). Twenty-three percent of eyes were in remission at last follow-up, 68% were inactive and 4% remained active. The median duration of follow-up was 5.8 years. We report the largest cohort of PGU. PGU were mostly idiopathic and had a high rate of complications. Sarcoid and idiopathic panuveitis are serious illnesses in which disease-modifying therapy should be initiated at diagnosis to improve management.

Endoscopic Endonasal Approach for Residual and Recurrent Craniopharyngioma after Transcranial Approach: A Multi-institutional Experience

Abstract Objectives While the endoscopic endonasal approach (EEA) has become a well-established surgery for resection of craniopharyngiomas (CP), the utility of this procedure following subtotal resection from open transcranial approach (TCA) surgery has yet to be explored. Here we present a multi-institutional case series of patients who underwent EEA for treatment of recurrent CP originally treated by TCA, demonstrating the viability of this approach as salvage surgery. Design Retrospective cohort. Setting Loyola University Medical Center and University of Pittsburgh Medical Center. Participants Patients who underwent EEA for recurrent CP following an initial TCA between 2003 and 2018. Main Outcome Measures Gross total resection (GTR) rate, surgical complications, visual outcomes, and endocrine outcomes Results Patients who underwent EEA for recurrent CP following a prior TCA had a GTR rate of 77%. EEA reoperation was not associated with worsening of visual outcomes as compared with the primary TCA (0% visual worsening after EEA reoperation vs. 40% after primary TCA, p = 0.055). While primary TCA resulted in worsening endocrinopathies in 100% of patients (including seven patients with permanent diabetes insipidus), subsequent EEA for re-resection of CP resulted in stable (30.8%) or improved (69.2%) endocrine function in all patients (p &lt; 0.001). Conclusions EEA achieves reasonable GTR rates and is an effective, safe surgical option for recurrent CP postinitial TCA. This approach demonstrated stable or improved visual and endocrinologic outcomes in all patients within our two-institution series. Thus, EEA should be considered as an efficacious form of retreatment in cases of progressive and recurrent CP.

Clinical characteristics of viral-associated Fuchs uveitis syndrome and Posner-Schlossman syndrome in a Chinese population.

To identify the types of viral infection in aqueous humor (AqH) among patients diagnosed as Fuchs uveitis syndrome (FUS) or Posner-Schlossman syndrome (PSS) and investigate their relevance to clinical manifestations and visual outcome. A total of 375 patients and 171 patients were diagnosed as FUS or PSS in our department. AqH and serum samples from 68 FUS patients and 16 PSS patients were obtained during eye surgery. The viral etiologies, clinical features, auxiliary tests and visual prognosis of patients with FUS or PSS who underwent AqH analysis were analysed and compared. Among 68 FUS patients, rubella virus (RV), cytomegalovirus (CMV), herpes simplex virus (HSV) and varicella-zoster virus were identified in 17, 11, 1 and 1 patients, respectively. Seven patients with CMV and 1 with HSV were identified in 16 PSS patients. In both FUS and PSS groups, virus-associated eyes had higher proportion of secondary glaucoma and worse visual prognosis as compared with non-virus-associated eyes (all P < 0.05). In FUS group, specifically, CMV infection manifested as more obvious anterior segment inflammation and lower corneal endothelial cell density (CECD). RV infection showed a higher percentage of vitritis. In PSS group, CMV-associated PSS had a lower retinal nerve fiber layer thickness and CECD, worse visual prognosis as compared with non-virus-associated PSS (all P < 0.05). Our study identified 4 types of viral infection in FUS and 2 types of viral infection in PSS. Virus-associated patients are usually associated with more obvious clinical signs and poor visual prognosis.
