Abstract |
PURPOSE To investigate the clinical features of 7 cases (8 eyes) of normal-tension glaucoma with the temporal visual defect only. METHODS: Patient's age, gender, systemic disease, refractive error, intraocular pressure, stereo disc photograph, nerve fiber layer photograph and visual field were analyzed. RESULTS: Age was 32+/-5 years, male:female ratio was 2:5 and 6 eyes were unilateral. Refractive error was -8.80+/-3.80 D, intraocular pressure was 16.0+/-1.90 mmHg and cup:disc ratio was 0.66+/-0.09 (horizontal) X 0.58+/-0.10 (vertical). There was disc hemorrhage in 1 eye, nasal cup in 1 eye, beta-type peripapillary atrophy in 2 eyes and undermining of nasal cup edge in 5 eyes. Pattern of temporal visual field defect, corresponding to the retinal nerve fiber layer defect were horizontal in 1 eye, cecopetal in one eye and cecofugal in 6 eyes. CONCLUSIONS: It is recommend to carefully evaluate nerve fiber layer in the young, high myopic patients showing undermining of nasal cup edge. |
