Chronic uveitis is a common extra-articular manifestation of juvenile idiopathic arthritis. The classic clinical picture is one of chronic anterior uveitis, which usually remains asymptomatic until ocular complications arise. The risk of uveitis is increased in girls with an early onset of oligoarthritis and positive antinuclear antibodies. Even though the inflammation in patients with juvenile idiopathic arthritis is initially limited in the anterior part of the eye, chronic active inflammation may eventually cause significant damage to the posterior pole. Complications may include band keratopathy, cataract, secondary glaucoma, posterior synechiae, cystoid macular edema, and hypotony. The cooperation of ophthalmologists with rheumatologists may help define the best treatment plan. The ophthalmic therapeutic regimen includes topical corticosteroids and mydriatics, while in severe cases immunosuppressive and biological agents are introduced. Surgical management of complications might be needed.

Introduction: Diabetic macular edema (DME), wet age-related macular degeneration (AMD) and macular edema due to central retinal vein occlusion (CRVO) are leading causes of vision loss, currently managed with anti-vascular endothelial growth factor injections (anti-VEGF). Aim of this study was to calculate QALYs in patients with DME, AMD and CRVO treated with anti-VEGF agents (QALYs+) in a Greek tertiary hospital setting and compare them to theoretical QALYs that the patients would have without treatment (QALYs-). Material and Methods: The study included 143 treatment-naive patients with macular edema due to DM (n=57), AMD (n=79) and CRVO (n=7), who received anti-VEGF injections as monotherapy according to the Treat-and-Extend (T&E) protocol. The anti-VEGF agents were ranibizumab and aflibercept in equivalent fractions. QALYs where calculated by the formula QALY = Utility Value * Time, where “time” refers to the follow-up period of the study. For QALYs-, we assumed that visual acuity remained unchanged during this period.Results: Mean follow-up time was 1+1.3 years in the DME group, 1.3 + 1.2 years in the AMD group and 0.5 +1 years in the CRVO group. For patients with DME, QALYs- were 0.75, and QALYs+ were 0.78 (QALY difference +0.033, p=0.439). For patients with AMD, QALYs- were 0.95 and QALYs+ were also 0.95 (QALY difference 0, p=0.45). QALYs- of patients with CRVO were 0.77, and QALYs+ were 0.80 (QALY difference +0.032, p=0.09).Discussion/Conclusion: QALYs+ were identical to QALYs- in patients with AMD and QALYs+ were minimally higher than QALYs- in patients with DME and CRVO in this specific Greek setting for a time horizon between 0.5 and 1.3 years. Possible explanations are the short time horizon used in this analysis and the inclusion of data from the better-seeing eye (BSE).
