Microstructure of Parapapillary Atrophy: Beta Zone and Gamma Zone

Abstract

In addition to associations with older age, increasing myopia, and larger disc size, the EDI-OCT-defined gamma zone of parapapillary atrophy was associated with the absence of glaucoma, whereas the EDI-OCT-defined beta zone was associated with the presence of glaucoma. Differentiation between the beta zone and the gamma zone may be clinically useful.
