RESUMEN
AIMS: To compare the safety and efficacy of methotrexate (MTX), mycophenolate mofetil (MMF) and azathioprine (AZA) in non-anterior sarcoidosis-associated uveitis. METHODS: Retrospective study including non-anterior sarcoidosis-associated uveitis according to the revised International Workshop on Ocular Sarcoidosis criteria. The primary outcome was defined as the median time to relapse or occurrence of serious adverse events leading to treatment discontinuation. RESULTS: 58 patients with non-anterior sarcoidosis-associated uveitis (MTX (n=33), MMF (n=16) and AZA (n=9)) were included. The time to treatment failure (ie, primary outcome) after adjustment for corticosteroids dose and the presence of vasculitis was significantly higher with MTX (median time of 34.5 months with MTX (IQR: 11.8 -not reached) vs 8.4 months (3.1-22.9) with MMF and 16.8 months (8.0-90.1) with AZA (p=0.020)). The risk of relapse at 12 months was more than twice lower in MTX as compared with MMF (p=0.046). Low visual acuity at the last visit was significantly lower with MTX (4% vs 9% in MMF vs 57% in AZA group (p=0.008)). Regarding all 75 lines of treatment (MTX (n=39), MMF (n=24) and AZA (n=12)), MTX was more effective than MMF and AZA to obtain treatment response at 3 months (OR 10.85; 95% CI 1.13 to 104.6; p=0.039). Significant corticosteroid-sparing effect at 12 months (p=0.035) was only observed under MTX. Serious adverse events were observed in 6/39 (15%), 5/24 (21%) and 2/12 (17%) with MTX, MMF and AZA, respectively. CONCLUSION: In non-anterior sarcoidosis-associated uveitis, MTX seems to be more efficient compared with AZA and MMF and with an acceptable safety profile.
RESUMEN
INTRODUCTION: 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. OBJECTIVES: To evaluate the demographics, aetiologies, complications, treatments, and visual prognosis of paediatric non-infectious granulomatous uveitis. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
RESUMEN
BACKGROUND/PURPOSE: Evaluate the performance of a deep learning algorithm for the automated detection and grading of vitritis on ultrawide-field imaging. METHODS: Cross-sectional noninterventional study. Ultrawide-field fundus retinophotographs of uveitis patients were used. Vitreous haze was defined according to the six steps of the Standardization of Uveitis Nomenclature classification. The deep learning framework TensorFlow and the DenseNet121 convolutional neural network were used to perform the classification task. The best fitted model was tested in a validation study. RESULTS: One thousand one hundred eighty-one images were included. The performance of the model for the detection of vitritis was good with a sensitivity of 91%, a specificity of 89%, an accuracy of 0.90, and an area under the receiver operating characteristics curve of 0.97. When used on an external set of images, the accuracy for the detection of vitritis was 0.78. The accuracy to classify vitritis in one of the six Standardization of Uveitis Nomenclature grades was limited (0.61) but improved to 0.75 when the grades were grouped into three categories. When accepting an error of one grade, the accuracy for the six-class classification increased to 0.90, suggesting the need for a larger sample to improve the model performances. CONCLUSION: A new deep learning model based on ultrawide-field fundus imaging that produces an efficient tool for the detection of vitritis was described. The performance of the model for the grading into three categories of increasing vitritis severity was acceptable. The performance for the six-class grading of vitritis was limited but can probably be improved with a larger set of images.

A 43-year-old woman presented bilateral anterior granulomatous uveitis associated with bilateral disc edema and bilateral peripheral retinochoroidal lesions. Intravenous corticosteroids after negative investigations for infectious causes did not prevent spreading of the lesions and retinal atrophy. A diagnostic vitrectomy with vitreous analysis, including pan-genomic, next-generation sequencing showed a positive result for rhinovirus HRV B91, and the cytological analysis was suggestive of infection. Intravenous immunoglobulins associated with pegylated interferon-alpha strongly slowed the progression of the lesions and led to scarred and atrophic aspect in both eyes after 6 months.

PURPOSE: To report the clinical features and treatment outcomes in adult Caucasians with ocular toxocariasis (OT) and investigate their prognosis depending on their serological status. METHODS: Retrospective observational cohort study (2016-2021) including consecutive adults with uveitis and positive western blot (WB) in the aqueous humor or vitreous. The presence of serum antibodies was not necessary for inclusion, allowing to compare the outcomes depending on the serological status. RESULTS: Seventeen eyes of 15 patients were included. Mean age at diagnosis was 51.9 years. Vitreous inflammation was the most frequent sign (100%). Vitreoretinal tractions (41.2%) and chorioretinal granulomas (58.8%) were less prevalent. Atypical features were: spontaneous intravitreal hemorrhage (23.5%), exudative retinal detachment (11.8%), isolated macular edema (17.6%), papillitis (29.4%) and vasculitis (47.1%). Twenty percent of patients had a positive serum serology. Baseline clinical features did not differ statistically depending on the serological status; however, the degree of inflammation was numerically higher in patients with negative serology. Overall, macular thickness, anterior and posterior segment inflammation improved significantly after treatment with oral albendazole, systemic ± local corticosteroids. Vitrectomy (47.1%) was performed in case of persistent vitritis (62.5%), retinal detachment (12.5%) and intravitreous hemorrhage (25%). CONCLUSION: OT has no pathognomonic sign and atypical presentations were not infrequent in this adult Caucasian cohort. Serum antibodies were rarely positive, stressing on the importance of ocular sample analysis, especially in case of atypical features. Serum antibodies may prove useful in forecasting the rapidity of inflammation clearance. Antiparasitic and anti-inflammatory treatment was safe and efficient in most cases.
RESUMEN
BACKGROUND/PURPOSE: To determine which retinal layer is primarily involved in intraretinal vascular processes associated with Toxoplasma retinochoroiditis using multimodal imaging, including optical coherence tomography angiography (OCTA). METHODS: Toxoplasma retinal lesions were analyzed through multimodal imaging, including color fundus photographs, fluorescein angiography, indocyanine green angiography, spectral-domain OCT, and OCTA. RESULTS: Two patients with atypical features of Toxoplasma retinochoroiditis are described in the acute phase. The first patient presented with a primary episode of acute Toxoplasma retinitis associated with an intraretinal abnormal vascular process that was detected at the acute phase by indocyanine green angiography and was better delineated by OCTA. Seven months later, the intraretinal vascular process had fully resolved on OCTA imaging. The second patient presented with a recurrence of active Toxoplasma retinochoroiditis adjacent to a pre-existing pigmented scar. He had a similar abnormal intraretinal vascular process that was identified on both fluorescein angiography at the early phase and indocyanine green angiography, which was also confirmed by OCTA imaging. CONCLUSION: We report a new finding associated with Toxoplasma chorioretinitis: an abnormal intraretinal vascular process that resolved without anti-vascular endothelial growth factor therapy but after toxoplasmosis treatment alone.

PURPOSE: To evaluate anatomical and functional changes in patients with vitreomacular interface disease after internal limiting membrane (ILM) peeling, using microperimetry along with usual clinical and multimodal retinal imaging. METHODS: Patients with vitreomacular interface disease requiring vitrectomy underwent multimodal retinal evaluation, including visual acuity assessment, fundus color photograph, Spectral-Domain Optical Coherence Tomography, Optical Coherence Tomography-Angiography, and microperimetry. They were examined at baseline (M0), 6 months (M6) and 18 months (M18) after surgery. Retinal sensitivity was subdivided into three concentric polygons: Large, Medium, Small. RESULTS: Eleven eyes of 11 patients were analyzed, including 10 epiretinal membranes (ERMs). Best-corrected visual acuity (BCVA) improved in all patients from 0.51 logarithm of the minimal angle of resolution (logMAR) to 0.067 (p = 0.0074). Retinal sensitivity improved between M0 and M6 in all polygons and continued to improve between M6 and M18 for polygons Medium (M) and Small (S) with no statistical significance. At M18, BCVA and retinal sensitivity were similar in the operated eye compared with the fellow eye for all patients. Dissociated optic nerve fiber layer appearance was observed in 8 patients at M18. It was not correlated with either retinal sensitivity or BCVA or microscotomas. No recurrence of ERM or macular hole occurred during follow-up. CONCLUSION: After surgery, the retinal sensitivity assessed by microperimetry gradually improved until the 18th month and was not different from the values of the fellow eye. These results seemed to confirm that ILM peeling can be an effective and safe technique to treat patients with vitreomacular interface disease.

We report the case of a man with a primary diagnosis of Waldenström macroglobulinemia. He secondarily presented a diffuse large B cell lymphoma (DLBCL) located in the nasal fossae, which relapsed later in the eye. The diagnosis of these two malignancies is based on a multidisciplinary biological approach using new sensitive and specific techniques. These techniques revealed that the two diseases harbor different B cell clones, indicating a distinct origin. This observation highlights the importance of targeted biological techniques for the diagnosis of these two rare hemopathies. It also shows that it is possible to prove the independent nature of the two tumor clones, thus allowing optimized therapeutic management.

There is increasing evidence of the survival benefit of treating uveal melanoma in an early stage, however it is important to discuss with the patient the associated risk of visual loss. We investigated visual outcomes for uveal melanomas staged T1 (T1UM) treated by proton beam radiotherapy (PBR) as a function of their distance to fovea-optic disc. This retrospective study included a cohort of 424 patients with T1UM treated with PBR between 1991 and 2010 with at least a 5-year follow-up. Visual acuity (VA) was analyzed for patients with posterior edge of tumor located at ≥3 mm (GSup3) or <3 mm (GInf3) from fovea-optic disc. The mean follow-up duration was 122 months, no tumor recurrence was observed. The mean baseline and final VA were 20/25 and 20/32 for GSup3 (n = 75), and 20/40 and 20/80 for GInf3 (n = 317) respectively. The frequency of a 20/200 or greater visual conservation was 93.2%(CI95%:87.7-99.1) and 60.1%(CI95%:54.9-65.9) for GSup3 and GInf3 respectively. This difference between groups was statistically significant (p < 0.001). The risk factors for significant VA loss (less than 20/200) were GInf3 location (p < 0.001), tumor touching optic disc (p = 0.04), initial VA inferior to 20/40 (p < 0.001), documented growth (p = 0.002), and age greater than 60 years (p < 0.001). In summary, PBR for T1UM yields excellent tumor control and good long-term visual outcomes for tumors located ≥3 mm from fovea-optic disc.
