- Abstract
Purpose: 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., Methods: 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., Results: 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)., Conclusions: 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., (© 2023. The Author(s), under exclusive licence to Springer Nature B.V.)

- Abstract
Purpose: To evaluate the changes in retinal microvasculature in eyes with anterior uveitis (AU) using optical coherence tomography angiography., Methods: Foveal avascular zone (FAZ) of superficial capillary plexus (SCP) and deep capillary plexus (DCP), vessel density (VD) of SCP, DCP, and choriocapillaris, and central macular thickness (CMT) and central foveal thickness (CFT) were calculated from 34 healthy and 41 uveitic eyes. The parameters were compared between the two groups., Results: The deep FAZ was significantly smaller in the eyes with AU during the attack than after recovery and the control group (p = 0.001 and p = 0.003, respectively). The VD in deep capillary plexus (DCP) in eyes with AU during the attack was significantly higher than the control group (p = 0.048). The VD in the foveal sector of DCP in eyes with AU during the attack and after recovery was significantly higher than the control group (p = 0.001 and p = 0.031, respectively). There was no significant difference regarding CMT, CFT, VDs of each segment and each sector, and superficial and deep FAZ between eyes with first uveitis attack and those with recurrent uveitis during the attack and after recovery (p > 0.05)., Conclusion: The results of this study show that there is a reduction in the FAZ and an increase in the VD of the DCP of the retina during active AU, and these findings are reversible. Acute AU may affect the macular microvasculature, which is usually temporary, especially in the DCP., (© 2021. The Author(s), under exclusive licence to Springer Nature B.V.)

- Abstract
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
Purpose: To investigate the types, frequency and clinical profiles of uveitic glaucoma seen at a tertiary care center and also to have an idea about the distribution of uveitic glaucoma types in Turkish population., Methods: Consecutive case notes of all patients attending a specialized uveitis clinic over a 3-month period were reviewed retrospectively., Results: One hundred and seven eyes of 96 patients were included. Sixty-five of the eyes had anterior, one intermediate, nine posterior uveitis while 32 of them had panuveitis. Twenty-three eyes had acute, 52 chronic and 32 recurrent uveitis. Herpes virus associated iridocyclitis was the leading cause of anterior uveitis-associated uveitic glaucoma followed by cytomegalovirus (CMV) associated anterior uveitis; while steroid-induced glaucoma accounted for the majority of chronic uveitis with glaucoma followed by Fuchs' uveitis syndrome (FUS). The most common causes of glaucoma among the cases were steroid-induced in 30 eyes (28%), Herpes virus anterior uveitis in 24 eyes (22%), CMV anterior uveitis in 20 eyes (18%), FUS in 15 eyes (14%), ocular toxoplasmosis in 5 eyes (4%). Behçet's uveitis was the most common (n = 11, 36%) cause of steroid-induced glaucoma. The need for surgical intervention was 23.32% (n = 25; 12 of them were FUS, 8 steroid-dependent, 1 HSV and 3 CMV anterior uveitis and 1 angle closure glaucoma with idiopathic uveitis) in our cases., Conclusion: Uveitic glaucoma is a common complication in a tertiary clinic. The most common causes are steroid-induced, FUS, viral anterior uveitis. The most common disease causing steroid induced glaucoma was Behçet's disease. Glaucoma surgery is required in a significant number of cases.

- Abstract
Purpose: To evaluate retinal microvasculature and blood flow during Behcet's uveitis (BU) remission via optical coherence tomography angiography (OCT-A), and compare the results with those from healthy eyes., Methods: A total of 35 eyes of 35 BU patients presenting during the remission period of BU involving the posterior segment were enrolled, as were 30 normal eyes of 30 age and sex-matched healthy participants. Optical coherence tomography angiograms were analyzed. Foveal avascular zone (FAZ), vessel densities, and flow areas were calculated and compared., Results: Thirty-five eyes of 35 BU patients and 30 normal eyes of 30 age and sex-matched subjects were included in the study. The superficial FAZ was slightly higher in the BU group than in the control group (p = 0.01), but deep FAZ was substantially higher (p < 0.001). Deep foveal and parafoveal vessel densities were significantly lower in BU eyes (p < 0.05). Flow areas in superficial and deep plexuses were lower in BU eyes (p < 0.05), however choroidal flow was similar (p > 0.05)., Conclusion: BU can cause permanent damage especially in the deep capillary plexus and OCT-A provides a detailed view of the retinal microvasculature which helps us to visualize vascular damage in these patients. Further studies with longer follow-up periods are needed to define the role of OCT-A in the decision of treatment efficacy with different agents., (Copyright © 2019 Elsevier B.V.

- Abstract
To evaluate the differences in the biometric parameters of iridocorneal angle and iris structure measured by anterior segment optical coherence tomography (AS-OCT) in Fuchs' uveitis syndrome (FUS). Seventy-six eyes of 38 consecutive patients with the diagnosis of unilateral FUS were recruited into this prospective, cross-sectional and comparative study. After a complete ocular examination, anterior segment biometric parameters were measured by Visante(®) AS-OCT. All parameters were compared between the two eyes of each patient statistically. The mean age of the 38 subjects was 32.5 ± 7.5 years (18 female and 20 male). The mean visual acuity was lower in eyes with FUS (0.55 ± 0.31) than in healthy eyes (0.93 ± 0.17). The central corneal thickness did not differ significantly between eyes. All iridocorneal angle parameters (angle-opening distance 500 and 750, scleral spur angle, trabecular-iris space (TISA) 500 and 750) except TISA 500 in temporal quadrant were significantly larger in eyes with FUS than in healthy eyes. Anterior chamber depth was deeper in the eyes with FUS than in the unaffected eyes. With regard to iris measurements, iris thickness in the thickest part, iris bowing and iris shape were all statistically different between the affected eye and the healthy eye in individual patients with FUS. However, no statistically significant differences were evident in iris thickness 500 μm, thickness in the middle and iris length. There were significant difference in iris shape between the two eyes of patients with glaucoma. AS-OCT as an imaging method provides us with many informative resultsin the analysis of anterior segment parameters in FUS.

To evaluate the microvasculature during remission in patients with pars planitis (PP-IU) and multiple sclerosis-associated intermediate uveitis (MS-IU) using optical coherence tomography angiography (OCT-A). Single-center, descriptive, case-control study was conducted. Adult patients (≥16 years) with IU in remission (PP-IU and MS-IU) and healthy age-sex matched healthy controls (HC) were enrolled to the study. Demographic/clinical features, best-corrected visual acuity (BCVA), ocular findings, neurological symptoms and preferred treatments were recorded. The presence of cystoid macular edema (CME) during follow-up was recorded. All IU patients in remission and HC subjects were scanned with OCT-A. Foveal avascular zone (FAZ) areas of superficial and deep capillary plexus (SCP/DCP) and vascular densities of SCP, DCP and choriocapillaris were obtained from OCT-A and compared between the groups. Sixty-nine eyes of 37 IU patients in remission and 20 HC were included (44 eyes/23 patients in PP-IU, 25/14 in MS-IU, 40/20 in HC). No statistically significant differences were observed in terms of demographic or clinical characteristics of the patients. The vascular density in the SCP was significantly reduced in the PP-IU and MS-IU groups compared to the HC group (p <.05). Nevertheless, there were no significant changes in any of the OCTA parameters between the IU groups. Uveitis duration was found to be correlated with enlargement of the FAZ area in PP-IU (p =.039). OCTA may not be useful in differentiating between PP-IU and MS-IU. Nevertheless, the primary implication in SCP potentially elucidates the pathogenesis of these two subtypes of IU, which are characterized by a shared pathogenesis. The monitoring of the FAZ area in the PP-IU group is valuable in terms of chronicity. [ABSTRACT FROM AUTHOR]
