Beta Zone and Gamma Zone Parapapillary Atrophy in Nonmyopic Eyes
Abstract
PRCIS: Not only β-zone but also ɣ-zone atrophy is observed in nonmyopic eyes. The presence of ɣ-zone atrophy reflects optic nerve head canal offset during eyeball expansion, and its directionality is associated with the offset direction. PURPOSE: To evaluate the locations of β-zone and ɣ-zone parapapillary atrophy (PPA) in nonmyopic eyes. METHODS: A total of 151 nonmyopic eyes with an axial length (AXL) of
