OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY SHOWS INNER CHOROIDAL ISCHEMIA IN ACUTE POSTERIOR MULTIFOCAL PLACOID PIGMENT EPITHELIOPATHY.

Abstract

To describe multimodal imaging findings of an evolving case of acute posterior multifocal placoid pigment epitheliopathy occurring in a young healthy male. Case report of a patient with acute posterior multifocal placoid pigment epitheliopathy including comprehensive systemic and ocular examinations. Ultra-widefield autofluorescence, fluorescein angiography, indocyanine green angiography, and serial optical coherence tomography angiography were performed. A 34-year-old male presented with acute vision loss in his left eye for 2 weeks. His best-corrected visual acuity was 20/20 in his right eye and 20/200 in his left eye. Dilated funduscopic examination revealed multiple creamy white deep retinal lesions showing macular involvement of the left eye with a diffuse area of pigmentary changes. The presence of multiple areas of hypoperfusion of the inner choroid were demonstrated with fluorescein and indocyanine green angiography. Serial optical coherence tomography angiography showed multiple evolving areas of decreased flow at the level of the inner choroid. Although the pathogenesis of acute posterior multifocal placoid pigment epitheliopathy remains unknown, there is growing evidence of a primary choroidal involvement with secondary damage to the overlying retinal pigment epithelium and the outer retinal layers. Optical coherence tomography angiography may provide valuable information for the diagnosis and follow-up of this condition avoiding invasive angiographic procedures.
