Bilateral Retinal Vasculitis as Initial Presentation of Systemic Lupus Erythematosus with Secondary Antiphospholipid Syndrome.

BACKGROUND Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease of undefined etiology with a relapsing and remitting course. Lupus retinopathy is reported in around 10% of patients with SLE; however, it is rarely the initial presenting feature of the disease. We report a unique case of bilateral retinal vasculitis as the initial presentation of SLE with secondary antiphospholipid syndrome (APS). CASE REPORT A 34-year-old man, previously healthy, presented to the eye clinic for the first time with painless reduced vision for 3 weeks. A review of systems revealed generalized fatigue, myalgia, arthralgias, and weight loss of around 10 kg in the last 3 months. On ophthalmic examination, his visual acuity was reduced bilaterally, more in the right eye. A fundus exam revealed bilateral diffuse multiple cotton-wool spots, dot and blot hemorrhage covering the posterior pole, and venous congestion and beading. In addition, there was cystoid macular edema (CME) in the fovea of both eyes, and fundus fluorescein angiography (FFA) showed bilateral areas of peripheral and macular hypo-fluorescence, multiple hyper-fluorescent knob-like aneurysmal dilatations, and vascular leaking and staining. He was diagnosed with SLE by the rheumatology team based on the clinical presentations and laboratory investigations. The patient was managed with intravenous methylprednisolone and discharged on oral prednisone with a tapering regimen. Eighteen months after, he reported significant improvement in his vision with regular follow-ups. CONCLUSIONS Ocular manifestations can be the initial presentation of SLE and can lead to serious ocular complications. Early diagnosis and proper management are essential and require cooperation between rheumatologists and ophthalmologists.
