She was under investigation for urinary abnormalities and reported a previous history of recurrent oral ulcers and ocular hyperemia in both eyes. Best-corrected visual acuity was 20/30 and 20/20 in the right and left eyes, respectively. Slit-lamp biomicroscopy of the ocular surface of the right eye revealed nasal scleral hyperemia that persisted after instillation of topical phenylephrine 10%, reinforcing the diagnosis of anterior scleritis. Renal biopsy showed immunoglobulin A immune complexes and confirmed the suspected diagnosis of Berger's disease. Maintenance immunosuppressive therapy with azathioprine following a 6-month induction of remission with cyclophosphamide was necessary after pulse therapy with methylprednisolone. Scleritis is usually related to systemic autoimmune diseases, such as rheumatoid arthritis, and polyangiitis. Herein, we describe a rare case of unilateral anterior scleritis associated with Berger's disease. Diabetic retinopathy is currently considered a chronic inflammatory disease involving NOD-like receptor family pyrin domain containing 3 inflammasome activation and retinal microglial pyroptosis. In this study, we aimed to investigate whether NOD-like receptor family pyrin domain containing 3 inflammasome signaling induces pyroptotic death of retinal microglia under high-glucose conditions. Retinal microglia were stimulated by high glucose levels for 24 h. Cell viability, lactate dehydrogenase release, and caspase-1 activity were detected in vitro. The expression of pro-inflammatory cytokine (interleukin-1β, activated microglia marker ionized calcium-binding adapter molecule-1), NOD-like receptor family pyrin domain containing 3, cleaved caspase-1, and cleaved gasdermin D were examined. Subsequently, retinal microglia were pretreated with the inhibitors of NOD-like receptor family py
