Capillary Density Measured by OCT Angiography in Glaucomatous Optic Disc Phenotypes
Purpose To compare optical coherence tomography angiography (OCTA) measured capillary density of the optic disc among four glaucomatous optic disc phenotypes. Design Cross-sectional study. Methods Circumpapillary capillary density (cpCD) of four glaucomatous optic disc phenotypes in 193 eyes of 141 glaucoma patients and cpCD in 92 eyes of 55 healthy subjects from the Diagnostic Innovations in Glaucoma Study (DIGS) were compared. Areas under the receiver operating characteristic curves (AUROC) were used to evaluate diagnostic accuracy among groups after adjusting for confounders. Results Four glaucoma phenotypes were assessed including focal ischemic (n=45), generalized cup enlargement (n=60), myopic glaucoma (n ...
