Optical coherence tomography findings in a case of an acute multifocal posterior placoid pigment epitheliopathy (AMPP).

Abstract

To report the optical coherence tomography (OCT) findings in a case of acute multifocal posterior placoid pigment epitheliopathy (AMPPPE). A 26-year-old woman was seen for a mild loss of visual acuity in both eyes. The fundus examination revealed yellow-white placoid lesions in the posterior pole suggesting AMPPPE. Fluorescein and indocyanine green (ICG) angiography and optical coherence tomography (OCT) were performed 2 days, 9 days, and 1 month after the first examination. In the acute phases the OCT revealed a mild hyperreflective area above the retinal pigmented epithelium (RPE) in the photoreceptor layer. In the later phases the OCT scan revealed a nodular hyperreflective lesion on the plane of the RPE with mild underlying backscattering. In AMPPPE, the OCT demonstrates hyperreflective lesions that may indicate inflammatory tissue and inflammatory cells or the presence of ischemic edema in the outer retinal layers.
