Ophthalmologic manifestations in patients with antiphospholipid antibodies: Beware of iatrogenic complications

Abstract

Background Antiphospholipid syndrome (APS) is characterized by several clinical manifestations such as venous and arterial thrombosis associated with persistent antiphospholipid antibodies (aPL). Several studies confirmed that retinal vein occlusion was the most common APS ocular manifestation. The purpose of this study was to identify ophthalmologic manifestations in a homogeneous cohort of well-defined persistently aPL-positive patients and to determine variables associated with these manifestations. Methods APL-positive patients were selected from two research programs. All ophthalmologic manifestations including those related to APS were recorded. Results A total of 117 patients were included and 10 of them had APS-related ophthalmologic manifestations (glaucoma, hydroxychloroquine-related maculopathy, anterior acute uveitis, anterior ischemic optic neuropathy). Systemic Lupus Erythematosus (SLE) (OR = 3.4[95%CI; 0.9-12.7), corticosteroids (OR = 9.0 [95%CI; 2.2-37.7]) and aPL-related nephropathy (OR = 7.1 [95%CI; 1.7-30.0]) were significatively associated with the risk of APS-related ophthalmologic manifestations. Conclusion Most of ocular manifestations in this study were iatrogenic related to corticosteroids or hydroxychloroquine. Patients with SLE, small vessel thrombosis in general, or with aPL-related nephropathy in particular, seemed at higher risk to develop APS-related ophthalmologic manifestations thus deserving adequate monitoring.
