[Acute posterior multifocal placoid pigment epitheliopathy. Case report].

BACKGROUND: Acute posterior multifocal placoid pigment epitheliopathy is an unusual, self-limited, inflammatory disease that affects the choriocapillaris, and external retinal layers.

CLINICAL CASE: A 26 year-old male patient complained of decreased visual acuity, as well as photopsia in both eyes for the past three days. Best corrected visual acuity was 20/200 in the right eye and 20/80 in the left eye. There was no anterior chamber inflammation or vitritis in either eye. There were plaque-like, cream-coloured sub-retinal lesions with ill-defined borders in the posterior pole of both eyes. Fluorescein angiography showed hypofluorescent lesions in early phases that corresponded to the lesions seen in the clinical examination. These lesions were hyperfluorescent in later phases of the angiography. Based on the clinical and angiographic findings, an acute posterior multifocal placoid pigment epitheliopathy diagnosis was made.

CONCLUSIONS: Acute posterior multifocal placoid pigment epitheliopathy is an inflammatory condition of unknown origin that is part of the differential diagnosis of placoid retinal diseases.
