Ohno-Matsui K, et al. - An observational case series is performed to ascertain qualities of peri-dome choroidal deepening (PDCD) surrounding dome-shaped maculas (DSMs) in highly myopic eyes. It was concluded that the PDCDs were common findings in highly myopic eyes with DSMs. PDCDs could be related to a dome-induced inward push of Bruch's membrane (BM) at the top of the DSM, leading to a compression of the subfoveal choroid and, because of an increased strain of BM on the dome's slopes, to a relative detachment of BM in the peri-dome region.
