A rare case of unilateral acute posterior multifocal placoid pigment epitheliopathy with features of Vogt-Koyanagi-Harada disease

Abstract

The purpose of this study is to report a rare case of unilateral acute posterior multifocal placoid pigment epitheliopathy (APMPPE) with features of Vogt-Koyanagi-Harada (VKH) disease. Both the diseases have their own unique presentations and can lead to vision loss in the affected eye. Overlapping features of both diseases in the same eye is rare. A 28-year-old healthy female presented with loss of vision in her right eye for 10 days duration. Visual acuity in the affected eye was 20/200, N36. Fundus examination revealed numerous creamy yellow lesions overlying the posterior pole with subretinal fluid. Further investigations including fundus fluorescein angiography and optical coherence tomography were suggestive of overlapping features of both APMPPE and VKH disease. Baseline laboratory investigations and markers for Sarcoidosis, Tuberculosis, and Syphilis were normal. The patient was treated with tapering doses of oral steroids. One month following initiation of treatment, the vision had improved to 20/20, N6 with complete resolution of subretinal fluid in the right eye. The overlapping clinical and imaging features suggest that both diseases may be a part of a common inflammatory process that secondarily damages the outer retinal structures.
