Correlation of optical coherence tomography with angiography in retinal pigment epithelial detachment associated with age-related macular degeneration.

Abstract

To correlate optical coherence tomography (OCT) with angiographic signs of choroidal neovascularization (CNV) in retinal pigment epithelial detachment (PED) associated with age-related macular degeneration (ARMD). Prospectively, the authors performed OCT in 35 eyes of 35 patients (30 men and 5 women with a mean age of 71.6 years [range, 56-76 years]) with ARMD. All 35 eyes had CNV in the area of PED or adjacent to it, which was shown by fluorescein or indocyanine green angiography. Cross-sectional images were obtained by the OCT scanning line through the CNV and PED. In 10 (56%) of 18 eyes in which the CNV was at the margin of the PED, a small PED was adjacent to the central, dome-shaped PED. There was a notch between the central and small mounds of PED. In 13 (76%) of 17 eyes in which the CNV was within the PED, a notch was seen in the dome-shaped PED, resulting in a contour with 2 mounds. One of the 2 mounds contained a highly reflective mass immediately beneath the detached retinal pigment epithelium in 8 (62%) of the 13 eyes. A tomographic notch in the PED may be diagnostically important as an indication of CNV beneath the detached retinal pigment epithelium in eyes with ARMD.
