Relentless Placoid Chorioretinitis With Branch Retinal Vein Occlusion and Secondary Peripheral Retinal Neovascularization

Abstract

Purpose: We report a case of relentless placoid chorioretinitis (RPC) that developed branch retinal vein occlusion and peripheral retinal neovascularization in one eye. Methods: A case report is presented. Results: A 33-year-old healthy man presented with decreased visual acuity (20/150) in both eyes. Slit-lamp examination revealed anterior chamber and vitreous inflammation. Multiple yellow-white lesions were evident in the macula and scattered throughout the fundus. Following workup, a diagnosis of RPC was made. The patient was started on Pred Forte (prednisolone acetate 1%) and atropine drops. Three months later, visual acuity improved to 20/70 and 20/100 in the right and left eyes, respectively. At this time, fundus examination and fluorescein angiography revealed peripheral retinal neovascularization. Sectoral scatter laser photocoagulation was performed in the areas of nonperfusion. Conclusions: We describe a novel presentation of RPC associated with branch retinal vein occlusion and retinal neovascularization. Although the pathophysiology of RPC is believed to be primarily a choroidal vasculitis, retinal vascular changes may also occur, as observed in other white dot syndromes.
