Purpose: To report a case of bilateral occlusive retinal vasculitis in a patient with autoimmunity. Methods: A case was analyzed and a literature review performed. Results: A 55-year-old woman with autoimmune diagnoses of Isaacs syndrome and inclusion body myositis (IBM) reported decreased vision for 3 months. A fundus examination showed peripheral intraretinal hemorrhages in the right eye and an inferotemporal subhyaloid hemorrhage with adjacent intraretinal hemorrhages and preretinal fibrosis in the left eye. Fluorescein angiography showed temporal peripheral leakage and capillary dropout in both eyes, consistent with occlusive vasculitis. Scatter laser treatment to peripheral areas of retinal nonperfusion was followed by an intravitreal bevacizumab injection. Four months later, vision had stabilized at 20/15 in both eyes and the peripheral leakage had resolved. Conclusions: This patient developed retinal vasculitis associated with the rare autoimmune neuromuscular disorders of Isaacs syndrome and IBM. An extensive workup showed the most plausible mechanism for the vasculitis was autoimmunity with a history of previously elevated antibodies levels associated with the antiphospholipid syndrome.
