Abstract: :
Purpose: To identify choroidal vascular connections of choroidal neovascular membranes using the OCT ophthalmoscope. Methods: 5 eyes with choroidal neovascular membranes on fluorescein and indocyanine green angiography were evaluated using the OCT ophthalmoscope. Coronal and cross sectional images were obtained and analyzed. Features were correlated with fundus photographs, fluorescein angiography, and indocyanine green angiography. Results:Lesion features and boundaries were completely characterized in all cases. Choroidal blood vessel location and morphology was identified using serial coronal OCT ophthalmoscope scans and correlated with early ICG images in all five eyes. Cross sectional images of choroidal neovascular membranes identified areas of discontinuity in the retinal pigment epithelium/Bruch's membrane complex band. Hypolucent areas identified within these discontinuities were correlated with hypolucent areas on coronal imaging suggesting connections with underlying choroidal vascular networks. Conclusions: Images obtained using the OCT ophthalmoscope appear to identify connections between choroidal neovascular membranes and the underlying choroidal vascular network.
