Increasing peripapillary atrophy is associated with progressive glaucoma.
OBJECTIVE
This study aimed to determine the incidence and degree of progression of peripapillary atrophy in progressive and nonprogressive glaucoma.


METHODS
A retrospective cohort study.


METHODS
A total of 75 eyes of 75 patients were examined.


METHODS
Qualitative assessment of optic disc, peripapillary atrophy,and visual field change was performed by three experienced, masked, independent observers.


METHODS
Rim-disc area ratio and peripapillary atrophy-disc area ratio were measured at baseline and follow-up with computer-aided planimetry.


RESULTS
Among 75 eyes studied with an average duration of follow-up of 8 years (range, 4-19 years), 33 (44%) showed progressive optic disc damage. Twenty-one (64%) of 33 eyes with progressive disc damage showed peripapillary atrophy progression, and 7 (17%) of 42 eyes without progressive disc damage showed peripapillary atrophy progression; this difference was significant (P < 0.01). In groups with and without peripapillary atrophy, no statistically significant differences were found for mean intraocular pressure, baseline rim-disc area ratio, or baseline peripapillary atrophy-disc area ratio. However, optic disc progression and visual field progression were statistically more frequent in the group with peripapillary atrophy progression (75% and 54%, respectively) than in the group without peripapillary atrophy progression (26% and 11%, respectively) (P < 0.01). There was a statistically significant correlation between measurements of peripapillary atrophy area increase and disc rim loss over time (r = -0.35, P = 0.002).


CONCLUSIONS
Progression of peripapillary atrophy is associated with progressive optic disc damage and progressive visual field loss in glaucoma and may be used as a marker for progressive glaucomatous damage.
