목적 : To investigate the risk and risk factors for newly developed visual impairment in treated normal-tension glaucoma (NTG) patients followed-up on for 10 years.
방법 : Patients with NTG, who did not have visual impairment at the initial diagnosis and had undergone intraocular pressure-lowering treatment for more than seven years, were included. Visual impairment was defined as either low vision (20/400 ≤ visual acuity (VA) < 20/60 and/or 10 degrees ≤ central visual field (VF) < 20 degrees) or blindness (VA 20/400 and/or central VF < 10 degrees) by World Health Organization criteria. To investigate the risk and risk factors for newly developed visual impairment, Kaplan-Meier survival analysis and generalized linear mixed effects modes were utilized.
결과 : During the 10.8 years’ mean follow-up period, 20 eyes of 16 patients were diagnosed as visual impairment (12 eyes as low vision, 8 as blindness) among 623 eyes of 411 patients. The cumulative risk of visual impairment in at least one eye was 2.8% at 10 years and 8.7% at 15 years. The risk factors for visual impairment from treated NTG were worse VF mean deviation (MD) at diagnosis and longer follow-up period.
결론 : The risk of newly developed visual impairment in the treated-NTG patients was relatively low. Worse VF MD at diagnosis and longer follow-up period were associated with development of visual impairment.
