Abstract:
ObjectiveTo explore the morphological features of macular subretina choroidal neovascularization (CNV) in high myopia with optical coherence tomography (OCT).Methods16 CNV cases (17 eyes) were examined with OCT, and compared with results of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA).ResultsCNV appeared in space under sensory retinal anterior to the retinal pigment epithelium in 12 of 17 eyes. In 5 eyes, CNV appeared as a highly reflective fusiform or irregular mass at the level of retinal pigment epithelium and choriocapillaris. 9 of 17 eyes were associated with serous neurosensory retinal detachment, 11 eyes with hemorrhagic pigment epithelium detachment (PED) and 14 eyes with edema and thickening of sensory retina. 12 eyes regressed and its morphological features changed after photo dynamical therapy (PDT).ConclusionOCT can be used to confirm the morphological features, location and size of submacular CNV. CNV appears as a highly or moderately reflective round mass which protrudes from the retinal pigment epithelium in most cases. The morphology and the size of this mass may change after treatment and during follow-up.
