PURPOSE: To determine whether retinal nerve fiber layer (RNFL) photographs can predict future glaucoma visual field damage. METHODS: In a prospective study, 158 red free photographs of the RNFL were made between November 1994 and June 1995. Twenty-eight eyes of 19 patients with ocular hypertension (repeated intraocular pressure over 21 mmHg and normal visual fields (Peristat 433 Rodenstock) at first examination) could be re-examined for an average time of 42.3 (SD 4.5) months. RESULTS: In only one eye with normal RNFL at the first examination did typical glaucoma visual field defects appear (6%), but in six of 12 eyes (50%) with photographically demonstrable RNFL defects. The difference was statistically significant. CONCLUSIONS: There is only a minor probability that visual field defects will appear during three to five years in eyes with normal RNFL photographs (6%), but about in 50% of eyes with originally found RNFL defects.
