Abstract

To estimate the rate of visual field progression in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG), we reviewed the medical records of POAG and PACG patients who had a minimum of 5-year longitudinal Goldmann visual field data. I4e and I2e isopters were quantified using grid systems. The rate of change was calculated from the slope of a linear fit to a series of average visual field scores. Twenty-three eyes of POAG patients and 25 of PACG patients were studied. The rate of visual field score change was -2.00 +/- 2.0% per year in the PACG group, and -0.81 +/- 1.0% per year inthe POAG group. In these two patient groups, who were on conventional treatment at two referral hospitals, better visual field on initial presentation yielded faster progression in the POAG group, while the higher average of highest intraocular pressure in each year during follow-up was related to faster progression in the PACG group.

Top: The grid template made up of 100 dots was used to score I4e isopter of the left eye Goldmann field (adapted from Esterman).3 Bottom: A small grid template also made up of 100 dot was used to score I2e isopter (adapted from Kwon et al).4
