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.

STUDY DESIGN

A retrospective cohort study.

PARTICIPANTS

A total of 75 eyes of 75 patients were examined.

MAIN OUTCOME MEASURES

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).

CONCLUSION

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.
