Purpose: To evaluate the relations between progression of glaucoma in visual field and peripapillary area change in normal tension glaucoma (NTG). Methods: We respectively evaluated 66 patients (66 eyes) with normal tension glaucoma; these patients were classified as progressive glaucoma group and non-progressive glaucoma group by visual field test. Interobserver and intraobserver agreement was evaluated for qualitative assessment. Zone β change was measured by Image J (National Institute of Health, Bethesda, USA) by two methods. One method used paired t-test and the other method used CV (correlation of variation) to define significant progression of zone β. Results: 46 patients (46 eyes) were classified as progressive glaucoma and 20 patients (20 eyes) were classified as non-progressive glaucoma. There was no statistically significant different change of zone β between two groups and there were no changes of zone β over coefficient of variation (CV). Conclusions: The measurement of change of zone β seems to be of no use in recognition of progression in normal tension glaucoma. J Korean Ophthalmol Soc 2012;53(6):807-812
