Assessment of the intraocular pathologies detected by preoperative B-Scan Ultrasound examination in patients having dense cataracts

The present study was planned in the Department of Ophthalmology & Department of Radiodiagnosis & Imaging Vardhman Mahavir Medical College & Safdarjung Hospital, New Delhi with support from the Department of Radiodiagnosis & Imaging, Heritage Institute of Medical Sciences, Varanasi from September 2019 to February 2020. Total 100 patients of diagnosed age related cataracts were enrolled in the present study. Diagnostic B-Scan Ultrasonography was performed in these patients preoperatively. Detailed history was taken and examination with Slit Lamp and Tonometry were done. A. Scan Biometry was performed in all the cases. Informed consent was taken. B-Scan ultrasonography using a standard USG machine (Sonomed B5500) equipped with a real-time high- frequency probe with the contact method was done. B-scan is a good diagnostic modality for preoperative evaluation of posterior segment pathologies in the presence of cataract. B-Scan ultrasonography should be performed routinely in pre-operative assessment of cataract patients to diagnose pathologies of posterior segment that may influence the surgical strategy and visual prognosis of patients after cataract surgery. Diagnosing and characterizing the abnormalities with great accuracy by B-scan not only helps in preoperative cases but also changes the management of various other patients.

Significance of outer retinal undulation on preoperative optical coherence tomography in rhegmatogenous retinal detachment

Rhegmatogenous retinal detachment (RRD) is a vision-threatening pathology. Optical coherence tomography (OCT) is useful for evaluating retinal damage and visual prognosis in patients with RRD. Outer retinal undulation (ORU) is often observed on preoperative OCT in RRD. Therefore, we evaluated the correlation between ORU seen on preoperative OCT and pre/post-operative factors in RRD. Patients with RRD (114 eyes) underwent reattachment surgery and ≥ 6 months of follow-up. According to the condition of the macula on preoperative OCT, cases were divided into macula-on RRD (65 eyes) or macula-off RRD (49 eyes). Patients were classified into acute (< 10 days), subacute (10–30 days), and chronic (> 30 days) symptom duration groups. Clinical findings, histories, and relationships with OCT findings, including ORU, were analyzed. Subacute symptom duration was significantly associated with ORU on preoperative OCT (p = 0.001) and had a higher prevalence of ORU (73.7%) than did acute (OR = 4.48) or chronic (OR = 7.467) durations. Ellipsoid zone (EZ) disruption was significantly associated with poorer best-corrected visual acuity (BCVA) than normal EZ integrity at 6 months postoperatively (p = 0.012). ORU on preoperative OCT suggests a 10–30 days morbidity duration in RRD. EZ integrity is useful for predicting postoperative BCVA in macula-off RRD.

Systemic Regulatory T Cells and IL-6 as Prognostic Factors for Anatomical Improvement of Uveitic Macular Edema.

PurposeTo investigate whether systemic immune mediators and circulating regulatory T cells (Tregs) could be prognostic factors for anatomic outcomes in macular edema secondary to non-infectious uveitis (UME).MethodsMulticenter, prospective, observational, 12-month follow-up study of 60 patients with UME. Macular edema was defined as central subfield thickness (CST) > 300 μm measured with spectral domain optical coherence tomography (SD-OCT). Serum samples and peripheral blood mononuclear cells (PBMC) were obtained from venous blood extraction at baseline. Serum levels of IL-1β, IL-6, IL-8, IL-17, MCP-1, TNF-α, IL-10, and VEGF were determined by Luminex. Tregs population, defined as CD3+CD4+FoxP3+ in PBMC, was determined by flow cytometry. Main outcome measure was the predictive association between searched mediators and CST sustained improvement, defined as CST < 300 microns or a 20% CST decrease, at 6 months maintained until 12-months compared to baseline levels.ResultsMultivariate logistic regression analysis showed an association between CST sustained improvement at 12 months follow-up and IL-6 and Tregs baseline levels. Higher IL-6 levels were associated with less events of UME improvement (OR: 0.67, 95% CI (0.45–1.00), P = 0.042), whereas higher levels of Tregs favored such improvement (OR: 1.25, 95% CI: 1.12–2.56, P = 0.049).ConclusionsIncreased levels of Tregs and reduced levels of IL-6 in serum may be prognostic factors of sustained anatomical improvement in UME. These findings could enforce the opportunity to develop more efficient and personalized therapeutic approaches to improve long-term visual prognosis in patients with UME.

Rapid Administration of High-Dose Intravenous Methylprednisolone Improves Visual Outcomes After Optic Neuritis in Patients With AQP4-IgG-Positive NMOSD.

Objective: The purpose of this study was to elucidate the rapid impact of high-dose intravenous methylprednisolone pulse therapy (1,000 mg/day for 3 days) on the eventual visual prognosis in patients with serum anti-aquaporin-4 immunoglobulin G (AQP4-IgG)–positive neuromyelitis optica spectrum disorders (NMOSDs) who had an attack of optic neuritis (ON).Methods: Data from 32 consecutive NMOSD patients (1 male and 31 female) with at least one ON attack, involving a total of 36 ON-involved eyes, were evaluated. The following variables at ON onset were evaluated: sex, age at the first ON episode, visual acuity at nadir, visual acuity after 1 year, duration from ON onset to treatment for an acute ON attack, cycles of high-dose intravenous methylprednisolone pulse therapy for the ON attack, and cycles of plasmapheresis for the ON attack. Among the 36 ON-involved eyes, 27 eyes were studied using orbital MRI with a short-T1 inversion recovery sequence and gadolinium-enhanced fat-suppressed T1 imaging before starting treatment in the acute phase.Results: In univariate analyses, a shorter duration from ON onset to the initiation of high-dose intravenous methylprednisolone pulse therapy favorably affected the eventual visual prognosis 1 year later (Spearman's rho = 0.50, p = 0.0018). The lesion length on orbital MRI was also correlated with the eventual visual prognosis (rho = 0.68, p < 0.0001). Meanwhile, the days to steroid pulse therapy and lesion length on orbital MRI did not show a significant correlation. These findings suggest that the rapidness of steroid pulse therapy administration affects the eventual visual prognosis independent of the severity of ON. In multivariate analysis, a shorter time from ON onset to the start of acute treatment (p = 0.0004) and a younger age at onset (p = 0.0071) were significantly associated with better visual outcomes.Conclusions: Rapid initiation of high-dose intravenous methylprednisolone pulse therapy is essential to preserve the eventual visual acuity in patients with serum AQP4-IgG-positive NMOSD. Once clinicians suspect acute ON with serum AQP4-IgG, swift administration of steroid pulse therapy before confirming the positivity of serum AQP4-IgG would be beneficial for preserving visual function.

Neuropatía óptica asociada con lesión de Dieulafoy

Objetivo: describir el caso de un paciente del Hospital de San José de Bogotá con hemorragia del tracto digestivo superior secundaria a lesión de Dieulafoy, que presentó cuadro compatible con neuropatía óptica anterior isquémica no arterítica (NOIANA). Se hace una revisión narrativa y búsqueda sistemática de la literatura para determinar las características clínicas, demográficas, tratamiento y pronóstico visual de los pacientes con NOIANA. Materiales y métodos: reporte de caso, revisión narrativa y búsqueda sistemática de la literatura en las bases de datos Medline (vía Ovid) y Embase de NOIANA secundaria a hipovolemia. Se analizaron las variables sociodemográficas, clínicas, diagnóstico, condiciones asociadas, tratamiento y pronóstico visual. El análisis estadístico se realizó mediante frecuencias absolutas y relativas. Resultados: la mejoría de agudeza visual final en los pacientes que presentaron un episodio de NOIANA es incierta. En 42% hubo algún tipo de mejoría de la agudeza visual, independiente del tratamiento recibido. Menos del 50% de los casos clínicos reportados incluidos en este estudio que recibieron tratamiento con corticoides intravenosos mejoraron la visión. Discusión: la NOIANA por choque hipovolémico es una entidad infrecuente y poco reportada que puede generar cambios irreversibles en la agudeza visual, por lo que es importante sospecharla y detectarla para dar un manejo oportuno. Este caso de NOIANA es uno de los pocos descritos como secundarios a hemorragia digestiva y el primero asociado con lesión de Dieulafoy.

ELONGATED PHOTORECEPTOR OUTER SEGMENT LENGTH AND PROGNOSIS OF CHRONIC CENTRAL SEROUS CHORIORETINOPATHY.

To evaluate the effect of elongated photoreceptor outer segment length on the visual prognosis of patients with chronic central serous chorioretinopathy after treatment using half-dose and half-fluence photodynamic therapy (reduced PDT). The study included 36 eyes of 36 patients with chronic central serous chorioretinopathy who underwent reduced PDT and were followed up for at least 1 year. Spectral domain optical coherence tomography measurement was conducted at baseline and 12 months after reduced PDT. Thereafter, the association between the best-corrected visual acuity (BCVA) at 12 months after reduced PDT and 7 baseline variables (age, symptom duration, BCVA, outer nuclear layer thickness, elongated photoreceptor outer segment length, height of subretinal detachment, and subfoveal choroidal thickness) was evaluated. Multivariate analyses using the model selection with the corrected Akaike Information Criterion index were performed. The optimal model for BCVA at 12 months only included baseline BCVA (coefficient = 0.90, P < 0.0001) and baseline elongated photoreceptor outer segment length (coefficient = -0.0016, P = 0.034), but not outer nuclear layer thickness. Elongated photoreceptor outer segment length was significantly associated with BCVA prognosis in patients with chronic central serous chorioretinopathy after reduced PDT and can be useful for predicting residual photoreceptor function during the active phase of chronic central serous chorioretinopathy.

Clinical and Optic Disc Characteristics of Patients Showing Visual Recovery in Leber Hereditary Optic Neuropathy.

The visual prognosis in Leber hereditary optic neuropathy (LHON) is generally poor. However, some individuals can have spontaneous visual recovery (VR) in one or both eyes by a mechanism that is not yet clearly understood. The purpose of this study was to determine whether certain clinical and optic disc features are associated with VR in patients with LHON. We retrospectively examined 80 eyes of 40 patients with LHON using clinical databases, fundus photographs, and high-definition spectral-domain optical coherence tomography (OCT) images. VR was defined as a gain of 3 or more lines of logarithm of the minimum angle of resolution (logMAR)-scaled visual acuity from nadir; this represents a doubling of the visual angle. Patients were divided into VR and nonrecovery (NR) groups. Using fundus photographs, we measured optic disc size and evaluated for the presence of optic disc features, including peripapillary telangiectasia, disc hyperemia, and swelling. We also measured the disc area, cup-to-disc ratio, and rim area of the optic disc using OCT. Twenty-one of 80 eyes (26%) had a VR. The VR occurred within 2 years after onset in 81% of cases. The VR group showed younger age at onset (21 vs 29 years, P = 0.017) and better visual acuity at the nadir (1.39 vs 2.16 logMAR, P < 0.001) compared with the NR group. Optic disc features, particularly peripapillary telangiectasia (P = 0.027) and disc hyperemia (P = 0.006), were more prominent in the NR group. The cup-to-disc ratio was significantly smaller (0.64 vs 0.71, P = 0.004) and the rim area was significantly greater (1.17 vs 0.85 mm, P < 0.001) in the VR group compared with the NR group. A younger age at onset and a less severe reduction of visual acuity at the nadir were associated with a higher probability of VR. Presence of peripapillary telangiectasia and optic disc hyperemia may serve as predictive factors for poor visual prognosis in patients with LHON.

Role of multifocal electroretinogram in the prediction of visual prognosis in patients with occult macular dystrophy

Background Occult macular dystrophy (OMD) is a rare hereditary macular dystrophy characterized by severe bilateral progressive loss of central vision with normal fundus appearance and normal fundus fluorescein angiography.Aim The aim of this study was to assess the correlation between multifocal electroretinogram (mf-ERG) parameters and best-corrected visual acuity (BCVA) in patients with OMD.Patients and methods In all, 20 eyes of 10 patients with OMD and 20 eyes of 10 age-matched and sex-matched normal individuals were included in this study. Full ophthalmic examination, fundus fluorescein angiography, optical coherence tomography, full-field ERG and mf-ERG were performed for all participants. The average amplitude density of P1 wave, amplitude, and implicit time of P1 and N1 waves were recorded in the five concentric hexagonal rings. Correlation between these mf-ERG parameters and BCVA (LogMAR) was analyzed.Results There were no statistically significant differences in age, sex, and refraction between the studied groups (P=0.54, 1.0, and 0.82, respectively). Mf-ERG parameters in OMD patients showed significant central depression with less affection of peripheral rings. The average amplitude density of P1 wave and the amplitude of P1 and N1 waves were significantly reduced in the central rings (rings 1, 2, and 3), with less impairment in paracentral areas (rings 4 and 5). The implicit time of P1 and N1 waves were significantly delayed across the central rings in OMD patients. The BCVA (LogMAR) was significantly negatively correlated with the amplitude of P1 and N1 waves (P≤0.001). The BCVA (LogMAR) was significantly positively correlated with the implicit time of P1 and N1 waves (P≤0.001). Multiple regression analysis demonstrated that the amplitude and latency of P1 and N1 waves in the central rings (1 and 2) were the most important determinants for BCVA.Conclusion Mf-ERG has a key role in the detection of OMD and can be considered as a valuable objective test for the detection of central/macular dysfunction. The amplitude and latency of P1 and N1 waves in rings 1 and 2 may be used as biomarkers for the prediction of visual prognosis in these patients.

Inner Nuclear Layer Microcyst Configuration, Distribution, and Visual Prognosis in Patients With Epiretinal Membrane After Vitrectomy and Membrane Peeling

Inner nuclear layer(INL) microcysts at central macula are a common finding in patients with epiretinal membrane (ERM) after vitrectomy and membrane peeling. Using en face mode of optical coherence tomography (OCT) angiography, patients with ERM after surgery were retrospectively reviewed to understand the configuration and distribution of microcysts as well as their impact on visual acuity. Forty-six eligible patients were enrolled and their baseline best-corrected visual acuities improved from 20/67 to 20/29 (P < 0.01) after surgery. Twenty-eight (60.9%) patients had microcysts that appeared at a median of 5 months after the surgery and persisted for mean 16 months follow-up. The microcyst appeared as spheroidal shape with length ranged from 20 to 80 μm and widths of 80 μm in average. They tend to group in cluster with a density of 245 microcysts per mm2. The frequency of microcyst distribution was 86%, 54%, 32%, 25% and 18% at the nasal, superior, inferior, temporal quadrants and central 1 mm, respectively. Linear regression analysis showed that INL microcysts at central and temporal quadrants were associated with poorer visual acuity (P = 0.02 and P = 0.01, respectively). The presence of INL microcysts in center subfield and involved wider area is a poor prognostic factor for visual outcomes.

Ethnicity and association with ocular, systemic manifestations and prognosis in 194 patients with sarcoid uveitis.

To determine the ophthalmological and extra-ophthalmological clinical characteristics and visual prognosis of patients with sarcoid uveitis in different ethnic groups. We retrospectively analysed the data from patients with sarcoid uveitis seen at two departments of Ophthalmology between December 2003 and December 2017. Patients presented biopsy-proven sarcoidosis and/or presumed sarcoid uveitis based on the following criteria: compatible thoracic imaging, associated with elevated angiotensin-conversion enzyme (ACE) and/or lymphocytic alveolitis on bronchoalveolar lavage fluid analysis (> 15% lymphocytes and CD4/CD8 > 3.5). Ophthalmological and general characteristics, as well as visual and global prognoses, were compared in three pre-defined ethnic groups: White Europeans, North Africans and Afro-Caribbeans. A total of 194 patients were included: 145 with biopsy-proven and 49 with presumed sarcoid uveitis. Overall, 68% were White Europeans while 20.6% were North Africans and 11.3% were Afro-Caribbeans. Sixty-nine per cent were women and the median age at presentation was 52.1years. Median ages at first ocular manifestation of the disease in Afro-Caribbeans and North Africans were respectively 34.3 and 43.1years, while it was 57.8years in White Europeans (p < 0.001). Ocular involvement was bilateral in 77.8% (n = 151) of the cases and nearly half of the patients had panuveitis (48.5%). Anterior uveitis was more frequent in Afro-Caribbeans (59.1%; p < 0.0001), while White Europeans presented more frequently with intermediate uveitis. There was a significantly higher frequency of systemic involvement of sarcoidosis in North Africans while White Europeans showed a higher frequency of isolated ocular involvement at onset and during follow-up. Afro-Caribbeans, who had a complete visual recovery in 72.7% of the cases, had a better visual prognosis than other ethnic groups (p = 0.025). In this large European series of sarcoid uveitis, we observed ethnicity-related differences regarding uveitis clinical presentation and visual outcome. Although good overall, the visual prognosis seems to be better in Afro-Caribbeans than in other ethnic groups.

Clinical staging and visual prognosis of patients with papilloedema

Introduction: Papilledema is one of the true neuro ophthalmic emergencies. Most patients with elevated intra-cranial pressure (ICP) present to ophthalmologist with non-visual symptoms such as headache, nausea, vomiting and sometimes CSF rhinorrhoea. Patients may also note transient obscuration of visual (TOV) -episodes of unilateral or bilateral vision loss lasting 5-15 seconds. Papilledema serves as an important indicator and warning signal of intracranial pathology. Materials and Methods: It was a cross-sectional study. Patients with papilloedema were examined for clinical stage (Early. Established, Chronic and Atrophic), aetiology, visual acuity, colour vision, contrast and perimetry. Results: The most common aetiology for papilloedema was found to be ICSOL. Maximum number of patients were found to have early papilloedema. The correlation showed that visual acuity, colour vision and contrast were less affected in early stages of papilloedema as compared to late stages. Keywords: Intra-cranial pressure, Papilledema.

&lt;p&gt;Giant cell arteritis: early diagnosis is key&lt;/p&gt;

Giant cell arteritis (GCA) is an inflammatory vasculitis typically affecting elderly that can potentially cause vision loss. Studies have demonstrated that early recognition and initiation of treatment can improve visual prognosis in patients with GCA. This review addresses the benefits of early diagnosis and treatment, and discusses the available treatment options to manage the disease.

Correlation of serum aquaporin 4 antibodies and condition and visual prognosis in patients with severe neuromyelitis optica spectral disorders

Objective To observe the correlation of serum aquaporin 4 (AQP4) antibodies and condition and visual prognosis in patients with severe neuromyelitis optica spectral disorders (NMOSD). Methods Fifty NMOSD patients with visual acuity of 20/200 or worse in at least one eye were enrolled in this retrospective analysis. There were 12 males and 38 females. The age ranged from 17 to 65 years, with the mean of (39.86±2.02) years. The patients were divided into two groups according to the serum AQP4-IgG status. The ophthalmologic examination, serum anti-nuclear antibodies (ANA), myelin oligodendrocyte glycoprotein (MOG) antibody detection and vision prognosis were compared and analyzed. Glucocorticoid therapy was delivered to 46 patients who were within 1 month of onset. The visual acuity of the patients after treatment was divided into complete recovery, partial recovery, stabilization and reduction, and the visual acuity of the two groups were analyzed. Results Among 50 patients, there were 30 (60%) seropositive patients (positive group), 20 (40%) seronegative patients (negative group). The positive group had significantly higher ratio of female to male (P=0.004), and more binocular optic neuritis (ON) (P=0.010) compared with the negative group. More recurrence ON were also found in the positive group, but without statistic difference between two groups (P=0.167). There was no difference of age, course, and vision damage degrees and abnormal orbital MRI scanning between two groups (P>0.05). Among 24 patients who underwent serum ANA detection in the positive group, 8 patients were positive. All of 18 patients who underwent serum ANA detection in the negative group were negative. The difference of the ratio of serum ANA positive patients between two groups was significant (P=0.030). Serum MOG antibody detection in the positive group was negative (0/10). Sixteen patients who underwent MOG antibody detection in negative group, 4 patients were positive. After treatment, there were 23.3%, 23.3%, 53.3% patients with vision of complete recovery, partial recovery and reduction in the positive group; 25.0%, 30.0%, 25.0% patients with vision of complete recovery, partial recovery and reduction in the negative group, respectively. There was no difference in proportion of vision with complete recovery and partial recovery between two groups (P=0.163, 0.607), but significant difference was observed in proportion of vision with stabilization and reduction between two groups (P=0.021, 0.048). Conclusions The positive serum AQP4 antibody is common in patients with severe NMOSD. The patients with AQP4 antibody in the serum are more likely combined with immunological serological markers and poor vision prognosis. Key words: Neuromyelitis optica; Visually impaired persons; Aquaporin 4

Quantitative analysis of external limiting membrane, ellipsoid zone and interdigitation zone defects in patients with macular holes.

To investigate the correlation between the length of external limiting membrane (ELM), ellipsoid zone (EZ) and interdigitation zone (IZ) defects and visual prognosis in patients undergoing macular hole (MH) surgery, using spectral-domain optical coherence tomography (SD-OCT). This is a retrospective, consecutive, observational case series study. Fifty-two eyes of 52 patients with primary MH were evaluated. A quantitative analysis of ELM, EZ and IZ defects was performed preoperatively and at 3 and 6 months postoperatively using SD-OCT. The correlation between pre- and postoperative ELM, EZ and IZ defects and the best-corrected visual acuity (BCVA) was investigated. The lengths of ELM, EZ and IZ defects correlated significantly with BCVA in each study period (P < 0.001). Preoperative measures of these band defects were also associated with visual outcomes 3 and 6 months after surgery (P < 0.05). Considering all preoperative parameters, the length of the ELM defect was the factor most strongly correlated with BCVA at 6 months (β = 0.643, P < 0.012). The integrity of the ELM was the only factor significantly associated with BCVA at 6 months (β = 0.427; P = 0.004). The preoperative length of the ELM defect is the strongest predictor of visual acuity after MH surgery. Postoperative integrity of the ELM is significantly associated with visual restoration after surgical treatment of MH.

Atopic keratoconjunctivitis complicated by Kocuria koreensis keratitis: the first case

BackgroundPatients with atopic dermatitis have a predisposition to Staphylococcus aureus and a Herpes simplex virus infection. The treatment of atopic diseases with steroid and immunosuppressive agents induces opportunistic infection. However, there is a concern regarding visual prognosis in patients with atopic keratoconjunctivitis (AKC) complicated with infectious keratitis. We report an unusual case of an atopic shield ulcer with Kocuria keratitis.Case presentationA 51-year-old Japanese man presented with a 14-day history of eye pain and visual loss in his left eye. At the initial examination, a shield ulcer was observed in the upper-central cornea of the left eye, and the conjunctiva in both eyes had a velvety appearance due to papillary formation, as well as hyperemia and swelling in the palpebral area. The shield ulcer showed white stromal opacification in the marginal zone with a coral-like appearance. Samples were obtained by corneal scraping, and Kocuria sp. was identified by microbiological examination including culture and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The 16S rRNA gene sequence analysis was performed using isolated Kocuria strain from the patient. The obtained DNA sequence showed 99% homology with Kocuria koreensis. The combination of corneal scraping and instillation of cefmenoxime antibiotic ophthalmic solution was considered useful for the treatment of Kocuria keratitis.ConclusionClinicians should be aware of Kocuria keratitis as a corneal complication of AKC, and that rapid diagnosis of Kocuria keratitis may improve visual prognosis.

SYSTEMIC RISK FACTORS IN BILATERAL PROLIFERATIVE DIABETIC RETINOPATHY REQUIRING VITRECTOMY.

The visual outcome after vitrectomy for proliferative diabetic retinopathy (PDR) is often poor. Bilateral vitrectomy has been especially associated with a poor visual prognosis in patients with PDR. The authors investigated the systemic risk factors for PDR requiring bilateral vitrectomy compared with unilateral vitrectomy. The authors retrospectively reviewed 86 consecutive patients with Type 2 diabetes mellitus with PDR who underwent vitrectomy. These patients were divided into 2 groups: bilateral vitrectomy within 1 year (n = 25) and unilateral vitrectomy (n = 61). The authors compared the systemic risk factors: age, sex, duration of diabetes, hemoglobin A1c, body mass index, estimated glomerular filtration rate, uric albumin, hypertension, dyslipidemia, history of ischemic heart disease, arteriosclerosis obliterans, and smoking. There were significantly more cases with severe renal dysfunction in the bilateral vitrectomy group compared with the unilateral one (estimated glomerular filtration rate <30 mL/minute/1.73 m; bilateral cases = 5/25; unilateral cases = 2/61; P = 0.02). The authors found that severe renal dysfunction may be a risk factor in PDR requiring bilateral vitrectomy, indicating that careful attention needs to be paid to prevent the progression of diabetic retinopathy to severe PDR in the other eye if patients have severe unilateral PDR and severe renal dysfunction.

Fuchs' Heterochromic Iridocyclitis in an Italian Tertiary Referral Centre: Epidemiology, Clinical Features, and Prognosis.

Purpose. To study epidemiology, clinical findings and visual prognosis of patients with Fuchs' Heterochromic Iridocyclitis (FHI). Methods. A retrospective analysis was performed on 158 patients with FHI. Thirty-five patients were observed only once; the remaining 123 had a mean follow-up of 30.7 months (50 of them had a mean follow-up of 63.5 months) and in those we assessed complications, medical and surgical treatment, and long-term visual prognosis. Results. Average age at uveitis diagnosis was 27.2 years and 18.3% of patients were children. Blurred vision (54.5%) and floaters (40.5%) were the most frequent presenting symptoms. Small to medium-sized keratic precipitates (95.6%), iris atrophy (86.8%), and vitreous opacities (91.2%) were the most common signs; the prevalence of cataract and IOP increase was 63.5% and 20.1%, respectively, and their incidence was 0.1 and 0.06 eye/year. Significant risk factor for visual loss was IOP increase at presentation (p = 0.02). At final examination 98% of the eye had a visual acuity ≥ 0.6, and topical (p < 0.001) and systemic (p < 0.001) corticosteroids therapy were used less frequently than before referral. Conclusions. FHI has a good visual prognosis, despite the significant incidence of cataract and glaucoma. A correct and prompt diagnosis might avoid unnecessary therapies and provide excellent visual outcomes.

Prevalence of and risk factors for endogenous endophthalmitis in patients with pyogenic liver abscesses.

Background/AimsAlthough pyogenic liver abscesses (PLAs) can be successfully treated, the visual prognosis of patients with endogenous endophthalmitis (EE) associated with a PLA is poor. Early diagnosis and prompt intervention may salvage useful vision. Therefore, we investigated risk factors for EE in patients with PLA, to facilitate early diagnosis.MethodsData from 626 patients diagnosed with PLA between January 2004 and July 2013 were analyzed retrospectively. Patients were divided into two groups: those with liver abscess-associated endogenous endophthalmitis (LAEE) and non-LAEE.ResultsThe prevalence of EE in PLA patients was 1.92%. The mean age for all patients (373 males, 59.6%) was 62.8 years. Upon multivariate logistic regression, a liver abscess or another systemic infection (odds ratio [OR], 5.52; p = 0.005), an abscess in the right superior segment (OR, 5.26; p = 0.035), and Klebsiella pneumoniae infection (OR, 3.68; p = 0.039), were risk factors for LAEE. The final visual outcomes of patients with LAEE included no light perception in seven, hand motion only in three, and decreased visual acuity in two. Vitrectomy and early intravitreal injections of antibiotics improved visual acuity and preserved useful vision.ConclusionsPLA patients with other systemic infections, abscesses in the right superior segment, and K. pneumoniae infection require close monitoring and early intervention to treat LAEE. Intravitreal antibiotic injections or early vitrectomy may salvage useful vision.

Clinical Manifestations and Outcomes of Syphilis-associated Uveitis in Northern Spain

Purpose: To describe the clinical characteristics and to assess visual prognosis of patients with syphilis-associated uveitis in northern Spain.Methods: Retrospective review of clinical records in eight general uveitis referral centers.Results: Since the year 2000, 50 patients have been diagnosed: 31 men and 19 women; median age was 41 (19–76) years. A total of 34% were co-infected with HIV and 24% presented systemic manifestations of syphilis. Median initial visual acuity and vision at last visit in 93 affected eyes was 20/50 (20/20–20/2000) and 20/22 (20/20–20/2000), respectively (p < .0001). The most frequent manifestation was papillitis (33.3%). Fifty percent of eyes with macular edema on admission presented worsening of visual acuity at last visit, whereas frequency of worsening in eyes without edema was 7.1% (p = 0.009).Conclusions: In our series, patients with syphilitic uveitis were more usually middle-aged men and were frequently co-infected with HIV. Although most patients showed posterior segment involvement, visual prognosis was good.

Baseline Factors Predictive of Visual Prognosis in Acute Postoperative Bacterial Endophthalmitis in Patients Undergoing Cataract Surgery

Although rare, postoperative endophthalmitis in patients undergoing cataract surgery can lead to anatomical or functional loss of the eye. Therapeutic strategies such as antibiotic prophylaxis and microbiological diagnosis are more effective with a target patient population. New prospective data are needed to identify prognostic factors. To identify baseline factors of visual prognosis in patients with acute bacterial endophthalmitis after cataract surgery. Prospective study of consecutive patients undergoing cataract surgery, enrolled from March 1, 2004, through December 31, 2005. We analyzed outcomes to determine the effect on the final visual outcome, defined as poor (visual acuity [VA] worse than 20/100) or good (VA 20/40 or better) using univariate and multivariate analysis. Four academic hospitals. Ninety-nine consecutive patients with cataract. Corneal phacoemulsification. Factors related to the cataract surgery (complications), initial clinical presentation, and microbiological diagnosis and the final VA. The significant baseline factors (at presentation) for good visual outcome (45% of the series) were the winter season, absence of complications during cataract surgery, initial VA, microbiological investigations revealing no microorganism or a coagulase-negative Staphylococcus species (CNSP), and fundus visibility. Quantitative factors associated with a good clinical prognosis were shorter duration of cataract surgery, younger age, and a hypopyon no greater than 1.5 mm. Significant factors associated with poor visual outcome were infection of the right eye, initial VA, corneal edema, a hypopyon larger than 1.5 mm, detection of bacterial species other than a CNSP, and the absence of fundus visibility. Multiple logistic regression analysis showed that high bacterial virulence was the only independent factor (odds ratio, 14.0 [95% CI, 2.7-71.0]; P = .001) for poor visual outcome. On the other hand, low bacterial virulence (odds ratio, 0.2 [95% CI, 0.03-0.6]; P = .01) and the absence of complications during cataract surgery (0.1 [0.01-0.4]; P = .003) were independent factors for good VA. Most clinical outcome factors in acute postoperative endophthalmitis can be identified at presentation. The bacterial virulence level is the main factor predictive of the final visual prognosis.
