Abstract
To investigate the relationship between the characteristics of optic disc rotation and visual field (VF) progression in patients with myopic open-angle glaucoma (OAG). We included 53 eyes from 53 myopic OAG patients who were followed-up over a 3-year period. The characteristics of optic disc rotation including the degree of optic disc rotation, direction of optic disc rotation, and optic disc rotation-VF defect correspondence were investigated. The rates of global and regional VF progression were compared with different characteristics of optic disc rotation. Thirty-seven eyes (69.8%) showed inferior optic disc rotation and 41 (77.4%) eyes showed optic disc rotation-VF defect correspondence. The inferiorly rotated optic discs with corresponding superior VF defect had faster VF progression in the superior peripheral region (P = 0.028) and superiorly rotated optic discs with corresponding inferior VF defect had faster VF progression in the inferior peripheral region (P = 0.031). The VF progression was restricted to the superior hemifield in the eyes with inferiorly rotated optic discs and corresponding superior VF defects. In myopic OAG patients, the direction of optic disc rotation might predict faster VF progression in the corresponding peripheral region.
