The authors followed up 54 eyes of 35 eyes of glaucoma for an average of 5.3 years. The series comprised primary open-angle glaucoma (POAG) including capsular glaucoma (23 eyes), chronic closed-angle glaucoma (CAG, eight eyes), and normal-tension glaucoma (NTG, 23 eyes). They used a Humphrey Visual Field Analyzer with the 30-2 program. Eyes with NTG showed significantly lower values of mean deviation (MD) (p 0.01) and significantly higher values of corrected pattern standard deviation (CPSD) (p 0.001). Neither MD nor CPSD was correlated with the progression of optic disc cupping in POAG or CAG. There was a tendency for visual field progression in NTG, except in three eyes when the intraocular pressure (IOP) was over 13 mmHg. Visual field progression was also significantly correlated with lower MD (p ≤ 0.05) and higher CPSD (p 0.01). These findings show that the IOP in NTG ought to be kept below 13 mmHg, particularly when MD is less than -5 dB or CPSD is over 6 dB. LA: Japanese
