Vessel Density Calculated from OCT Angiography in 3 Peripapillary Sectors in Normal, Ocular Hypertensive, and Glaucoma Eyes

Abstract

Our cases suggest that PADF measurements can identify decreased peripapillary perfusion early in the glaucomatous RNFL thinning process, prior to the development of clinically significant RNFL damage and visual field deterioration. Decreased PAFD corresponds spatially with the damaged RNFL bundles. The results suggest that prospective studies using PAFD may help to understand the role of vascular dysfunction in glaucoma.
