Abstract

Optical Coherence Tomography- Angiography (OCT-A) can separately detect the superficial vascular plexus and the deep vascular plexus. Paracentral acute middle maculopathy (PAMM) is an idiopathic or secondary entity to a local retinal vascular or systemic disease, characterized by capillary vascular occlusions. Some authors recognize it as a variant of acute macular neuroretinopathy (AMN). In general, the most frequent findings in the acute phase are a slight decrease in deep capillary plexus (DCP) perfusion, and hyperreflectivity of the middle layer; in the chronic phase, the findings are DCP hypoperfusion and hyporeflectivity of the middle layer.
