Retinal Pigment Epithelium Aperture Preceding Collapse of Vascular and Avascular Pigment Epithelial Detachments Secondary to AMD

To describe retinal pigment epithelium (RPE) aperture preceding the collapse of retinal pigment epithelium detachments (RPED) in eyes with neovascular and non-neovascular age-related macular degeneration (AMD).Medical records from five patients with RPE aperture associated with vascular and avascular RPED were reviewed between 2010 and 2021 at the New England Eye Center at Tufts Medical Center. Main outcome measures were analysis of RPE aperture characteristics and temporal course of RPED collapse.RPE apertures were identified in six eyes from five women (mean age of 72.6 years). Two eyes had neovasacular AMD and four eyes had non-neovascular AMD. The RPE aperture initially appeared as a discontinuity at the apex of the RPED without rippling or retraction. Each aperture was associated with hypertransmission of OCT signal into the choroid as well as hyperreflective foci. The mean time between the appearance of the RPE aperture to near complete collapse of the RPED was 9 months. Following RPED collapse, one eye developed choroidal neovascularization, three eyes progressed to geographic atrophy, one eye had recurrence of the RPED, and one eye remained unchanged.RPE aperture is a characteristic OCT finding that can be observed in avascular or vascularized RPED secondary to AMD. RPE apertures precede RPED collapse, which are most likely to occur within nine months of RPE aperture detection.
