To understand the characteristics of visual field progression in myopic glaucoma according to the morphology of optic nerve head
The open angle glaucoma patients with and without myopia who visited at the glaucoma clinic in Samsung Medical Center between January 2014 and December 2014 were included. The follow-up period of the included patients should be over 5 years and the visual field tests over 10 times should be performed. The characteristics of visual field pattern were compared between the glaucoma with and without myopia. Among the myopic eyes, the subgroups were divided into temporal tilted disc and inferior tilted disc and visual field progression pattern were compared between the two groups. In the inferior tilted disc, the subgroups were classified into progression, stationary, and progression-to-stationary groups, and the clinical characteristics of visual field progression were compared among the subgroups.
There was significant difference in pattern standard deviation (PSD) and visual field asymmetry between OAG with and without myopia (P = 0.002; P < 0.001, respectively) In myopic OAGs, there were significant difference in baseline and final both hemifield involvement cases between myopic OAG with temporally tilted disc and inferioly tilted disc (P < 0.001; P < 0.001, respectively). In the analysis of the subgroups of glaucoma with inferiorly tilted disc, the progression group and the progression-to-stationary group showed younger ages than the stationary group (P = 0.01; P = 0.01, respectively). The follow-up period of the progression-to-stationary group was longer than the progression and the stationary groups (P < 0.001; P < 0.001, respectively).
It is likely that the characteristics of visual field progression is associated with the morphology of the optic nerve head tilt in myopic glaucoma.
