En Face Optical Coherence Tomography Imaging of Deep Capillary Plexus Abnormalities in Paracentral Acute Middle Maculopathy.

The authors describe a case of para-central acute middle maculopathy (PAMM) in a 75-year-old man who had recently undergone cardiac catheterization. Imaging with simultaneous en face optical coherence tomography (OCT) and OCT angiography (OCTA) revealed signal abnormalities localized to the deep capillary plexus. This case highlights the ability of OCTA to image and localize retinal disease by vascular distribution, previously difficult with conventional fluorescein angiography, and lends evidence to the belief that PAMM is caused by vascular injury to the intermediate and deep capillary plexus.
