  • Abstract
  • Look Inside

We followed up 26 eyes of 13 patients of normal-tension glaucoma. The patients were aged from 42 to 65 years, average 57.5 years, at the start of follow-up. The duration of follow-up averaged 11.7 years. The visual field was evaluated using an Humphrey Visual Field Analyser. The visual field was judged as progressed when the mean deviation and/or corrected pattern standard deviation increased by 3 dB or more from the initial value. Out of the 26 eyes, the visual field defect progressed in 13 eyes of 9 cases. The visual acuity remained intact in 23 eyes during the follow-up. There was no difference in the progression of visual field defect between younger and older age groups. There was a tendency for advanced visual field defect to progress further, sug-gesting the need for a careful follow-up on case-to-case basis. The present findings show that deterioration of visual field in normal-tension glaucoma is much more gradual than hitherto reported.
