Purpose: The authors describe high-pass resolution perimetry findings during the first five years of antiglaucoma treatment.
Patients and methods: Thirty-seven patients were examined six times, once a year for five years, with best corrected visual acuity, applanation tonometry, slitlamp examination, funduscopy, and high-pass resolution perimetry. Twenty-nine of these were treated for glaucoma and eight followed for ocular hypertension without treatment.
Results: The resolution thresholds in the treated group improved during the first two years and deteriorated after that back to baseline level. Regarding individual patients, the visual fields were improved in 4, unchanged in 16, and deteriorated in 13 of the 29 treated glaucoma patients at the end of the study period.
Conclusions: Resolution visual fields showed initial improvement and subsequent deterioration in treated patients with early glaucoma. The conventional therapy, aiming at reducing intraocular pressure, appeared to postpone visual field decay for at least five years in about 50% of the patients.
