Glaucoma progression on optic disc imaging.

Notes: Kaplan–Meier plot shows progression-free time on Heidelberg Retina Tomograph (HRT). Mean progression-free time was 6.6 years on HRT with a survival ratio of 50%. Patients were counted as having “confirmed progression” or “no progression” until the time of the last follow-up or if the definitions of progressions were not fulfilled and were marked as censored. Others include normal tension glaucoma, pigmentary glaucoma, secondary glaucoma, chronic angle-closure glaucoma, and ocular hypertension.

Abbreviations: HRT, Heidelberg Retina Tomograph; PEXG, pseudoexfoliation glaucoma; POAG, primary open-angle glaucoma.
