Purpose: This study measured the macular thickness, peripapillary retinal nerve fiber layer (RNFL) thickness, subfoveal choroidal thickness (SFCT), and ganglion cell complex (GCC) thickness in eyes with Fuchs uveitis syndrome (FUS).Methods: In total, 25 patients with unilateral FUS were enrolled. The diagnosis of FUS was based on the presence of several of the following clinical features: absence of acute symptoms and ciliary injection; small to medium-sized and stellate keratic precipitates (KP) diffusely scattered on the entire corneal endothelium; chronic low-grade anterior chamber inflammation; iris stromal atrophy with or without heterochromia; lack of posterior synechiae; iris nodules; and vitreous cells and debris. Spectral domain optical coherence tomography (SD-OCT; RTVue-100 OCT) was used to obtain the measurements. The SFCT, RNFL thickness, macular retinal thickness, and GCC thickness of the eyes with FUS were measured and compared with those of the uninvolved fellow eyes. A paired samples t-test was used for statistical analyses. A value of p<0.05 was considered to be statistically significant for all analyses.Results: The mean age of the patients was 35.2 ± 4.8 years. Fifteen patients (60%) were male, and 10 (40%) were female. Small- to medium-sized stellate KPs and mild anterior chamber reactions were seen in all patients. Heterochromia was observed in 24% of the eyes, iris nodules in 36% of the eyes, lens opacity in 44% of the eyes, and vitreous cells and debris in 88% of the eyes. The mean SFCT was significantly thinner in eyes with FUS (296.47 ± 32.29 µm) than in the fellow eyes without FUS (324.47 ± 26.73 µm; p = 0.001). The mean average GCC thickness was found to be 101.09 ± 5.46 µm in eyes with FUS and 103.80 ± 6.65 µm in eyes without FUS (p = 0.023). There were no significant differences in the mean RNFL and macular thickness values.Conclusions: We detected subfoveal choroidal thinning in eyes with FUS when compared with the uninvolved fellow eyes. In our opinion, thinning of the SFCT in FUS might be associated with autoimmune responses and chronic inflammatory processes. [ABSTRACT FROM AUTHOR]- Published

Purpose: To evaluate correlation between visual field indices and spectral domain optical coherence tomography (SD-OCT) parameters and correlation among SD-OCT parameters to have a better understanding of role of SD-OCT parameters in clinical practice. Materials and Methods: This is a retrospective controlled clinical study. Three hundred forty-three eyes (91 healthy, 80 ocular hypertension, 97 preperimetric glaucoma and 75 early glaucoma eyes) were analyzed. Retinal nerve fiber layer (RNFL), macular, optic nerve head (ONH) parameters were measured with SD-OCT. Correlation between visual field indices and SD-OCT parameters and correlation among SD-OCT parameters were calculated. Results: Average RNFL showed the best correlation with both mean deviation (MD) (r = 0.624) and pattern standard deviation (PSD) (r = 0.614). Other RNFL parameters, ganglion cell complex (GCC) parameters and total retina (TR) parameters showed moderate correlation whereas outer retina (OR) and ONH parameters showed poor correlation with MD. Correlation between RNFL and GCC parameters was strong. Correlation between RNFL and TR parameters was moderate. Poor correlation were found between OR parameters and both RNFL and GCC parameters. Moderate correlation was found between average RNFL and both rim area and rim volume. Other correlations with ONH parameters were poor. Conclusion: Good structure function relationship is present between visual field indices and SD-OCT parameters like RNFL and GCC parameters. These parameters reflect the severity of glaucoma and can be used for glaucoma monitoring. TR and some ONH parameters like rim area and volume can give supplementary information to use in clinical practice. [ABSTRACT FROM AUTHOR]

Purpose: To assess the effect of low, moderate, and high myopia on the thickness of the retinal nerve fiber layer (RNFL) and Ganglion cell complex (GCC) measured by Spectral Domain Optical Coherence Tomography (SD-OCT) in non-glaucomatous subjects.Methods: The subjects were divided into three groups: low (n = 81, 35.6%), moderate (n = 79, 34.8%), and highly myopic eyes (n = 67, 29.5%). The RNFL thickness profile, including the average, superior, nasal, inferior, and temporal quadrant and each of the eight directional thicknesses, was measured. GCC parameters, including the average, superior, and inferior values, the focal loss volume (FLV), and the global loss volume (GLV), were measured. The correlation between the OCT measurements and the axial length was evaluated.Results: The average, superior, inferior, and nasal RNFL thicknesses of low and moderate myopic eyes were found to be significantly higher than those of highly myopic eyes. The temporal RNFL thicknesses were not different among the three groups. The average, superior, and inferior ganglion cell complex values of low and moderate myopic eyes were significantly higher than those of highly myopic eyes. The FLV and GLV of low and moderate myopic eyes were significantly higher than those of highly myopic eyes (p = 0.001 for all). In the moderate and high myopia groups, the average RNFL thickness and GCC thickness were both negatively correlated with the axial length.Conclusion: Highly myopic subjects tend to have thinner RNFL and GCC thicknesses than subjects with low and moderate myopia.

Purpose: To develop an algorithm for the diagnosis of Behçet's disease (BD) uveitis based on ocular findings. Methods: Following an initial survey among uveitis experts, we collected multi-center retrospective data on 211 patients with BD uveitis and 207 patients with other uveitides, and identified ocular findings with a high diagnostic odds ratio (DOR). Subsequently, we collected multi-center prospective data on 127 patients with BD uveitis and 322 controls and developed a diagnostic algorithm using Classification and Regression Tree (CART) analysis and expert opinion. Results: We identified 10 items with DOR >5. The items that provided the highest accuracy in CART analysis included superficial retinal infiltrate, signs of occlusive retinal vasculitis, and diffuse retinal capillary leakage as well as the absence of granulomatous anterior uveitis or choroiditis in patients with vitritis. Conclusion: This study provides a diagnostic tree for BD uveitis that needs to be validated in future studies. [ABSTRACT FROM AUTHOR]

A 21-year-old girl presented with acute painless vision loss in her right eye. There was no remarkable ocular history and she had a history of anorexia nervosa. At presentation best-corrected visual acuities were counting fingers from 2 meters and 20/20, in the right and left eyes, respectively. Slit lamp examination result was normal. Fundus examination revealed multiple cotton wool spots and intraretinal hemorrhages surrounding the optic disc and macula in the right eye. Fluorescein angiography showed capillary filling defect and leakage from optic disc in the late phase of the angiogram. One week later best-corrected visual acuities remained the same in both eyes with similar fundus appearance. One month after initial presentation visual acuity was 20/20 in both eyes with no abnormality in fundus appearance. [ABSTRACT FROM AUTHOR]
