[Long-term effects of isopropyl unoprostone monotherapy on intraocular pressure and visual field for normal-tension glaucoma and primary open-angle glaucoma patients].
We retrospectively investigated the long-term effects of isopropyl unoprostone monotherapy on intraocular pressure and visual field for normal-tension glaucoma and primary open-angle glaucoma patients. Among 80 eyes of 49 subjects receiving isopropyl unoprostone monotherapy for 2 years or more, 32 eyes of 32 subjects were analyzed because of the good reliability of their visual acuity and visual field (age, 68.1 +/- 10.1 yrs, follow-up period 47.8 +/- 14.7 months). The mean values of intraocular pressure and visual field indices were compared with baseline data before medication. The visual field changes were also analyzed using the Kaplan-Meier life-table method. The mean intraocular pressure decreased for 4 years from 14.7 +/- 4.3 mmHg (mean +/- SD) at baseline, to 12.7 +/- 4.4mmHg at 4 years. The global index of visual field (mean defect, loss variance) did not change significantly during the 4 years. The accumulative probability of survival was 80.7 +/- 8.0% after 4 years when the endpoint was defined as 3dB progression in mean defect. Isopropyl unoprostone might have the possibility of stabilizing the visual field for a long period of time.
