Retro-mode imaging in acute posterior multifocal placoid pigment epitheliopathy

to provide a detailed description and multimodal imaging (MMI) including retro-mode imaging of acute posterior multifocal placoid pigment epitheliopathy (APMPPE).

Case report of a young male patient presenting with APMPPE picture. Initially, visual acuity testing was performed, followed by biomicroscopic and fundus examinations along with MMI including Optical Coherence Tomography (OCT), fundus autofluorescence (FAF), fluorescein angiography (FA), Indocyanine Green (ICG) angiography, and Retro-mode imaging. The patient was then monitored over a duration of two months.

visual acuity was 20/20 with normal biomicroscopic examination; fundus examination detected multiple pale placoid lesions. MMI was consistent with typical APMPPE. Notably, Retro-mode imaging revealed numerous crater-like round lesions that corresponded to those observed on angiography.

Retromode imaging in APMPPE can serve as a non-invasive tool that highlights the number and distribution of lesions as well as on angiography.
