Occlusive retinal vasculitis associated with systemic sclerosis and antiphospholipid antibodies

Abstract

Purpose To report a series of patients with occlusive retinal vasculitis associated with systemic sclerosis (SSc) and elevated antiphospholipid antibody titers. Method Case series. Main outcome measures included clinical and fluorescein angiographic findings at presentation and over time. Observations Case 1 - A 61-year-old woman initially diagnosed with idiopathic, bilateral panuveitis and retinal vasculitis causing peripheral nonperfusion was subsequently diagnosed with limited cutaneous systemic sclerosis (lcSSc). Her ocular inflammation and retinal vasculitis were controlled with topical and periocular corticosteroids, but she eventually developed peripheral retinal vascular occlusion that progressed to macular ischemia 11 years after presentation. Repeat serologic evaluation detected interval development of antiphospholipid antibodies. Case 2 – A 58-year-old woman was found to have bilateral peripheral nonperfusion and retinal neovascularization in her right eye. Given her elevated hemoglobin A1c of 8.5%, she was diagnosed with presumed proliferative diabetic retinopathy. Three years after initial presentation, she was diagnosed with lcSSc. Subsequent serum workup detected elevated B2-glycoprotein antibody titers. Her peripheral nonperfusion progressed despite adequate glycemic control, resulting in further neovascularization in each eye. Case 3 – A 40-year-old woman with diffuse cutaneous systemic sclerosis (dcSSc) and elevated titers of anti-cardiolipin antibodies developed multiple branch retinal artery occlusions with subsequent neovascularization of the retina, optic disc, and angle in the right eye. Conclusion and Importance Vision-threatening occlusive retinal vasculitis may develop in select patients with SSc. The presence of elevated anti-phospholipid antibody titers may confer increased risk for this vision-threatening complication.
