Choroidal Involvement in Acute Posterior Multifocal Placoid Pigment Epitheliopathy
2016
To evaluate choroidal involvement in acute posterior multifocal placoid pigment epitheliopathy (APMPPE).Retrospective study in five eyes of three patients evaluated through multimodal imaging, including enhanced-depth imaging optical coherence tomography (OCT), ultra-wide field color photography, fundus autofluorescence, and fluorescein angiography (FA). Choroidal thickness and structure were evaluated on OCT.During the acute phase, choroidal OCT showed choroidal thickening and a lucency at the level of the inner choroid. Subclinical lesions detected in the retinal periphery using wide-field retinal imaging were isoautofluorescent and corresponded to choriocapillaris filling-defects on FA. At final follow-up, all patients showed resolution of choroidal thickening and the inner choroidal lucency, as well as the disappearance of subclinical lesions.These results suggest a transient ischemic choroiditis in APMPPE that may lead to secondary permanent retinal pigment epithelium damage in the posterior pole but not in the retinal periphery.
