BACKGROUND: The present study aimed to compare visual field progression in new-diagnosed exfoliation versus open-angle glaucoma patients.
METHODS: Retrospective study. The study included patients with new-diagnosed primary open-angle and exfoliation glaucoma. All patients were followed for 3 years with reliable visual fields. At least five reliable fields were needed for inclusion. Exfoliation and open-angle glaucoma were defined based on the European Glaucoma Society guidelines. Visual field evaluation was performed using the software threshold 24-2 of the Humphrey Field Analysis.
OUTCOMES: Visual field progression. For visual field progression, three different strategies were used: mean deviation (MD), visual field index (VFI), and the guided progression analysis (GPA).
RESULTS: The study included 128 subjects, of the 54 in the open-angle and 74 in the exfoliation glaucoma group. The MD difference values were higher in the exfoliation (- 3.17 dB) than in the primary open-angle (- 1.25 dB) glaucoma group in the three-year follow-up period. The difference between groups was significant (t-test, p = < 0.001). The difference in VFI was calculated for the 3 years follow-up period. The difference was higher in the exfoliation (- 7.65%) than in the primary open (- 1.90%) glaucoma group (t-test, p = < 0.001). The GPA showed progression in 58% of cases in exfoliation, and 13% in primary open glaucoma group (Chi-square, p = < 0.001).
CONCLUSION: The present study found a more frequent and faster visual field progression in exfoliation than in primary open-angle glaucoma patients. New-diagnosed exfoliation glaucoma patients must be controlled and treated more strictly than primary open-angle glaucoma patients to avoid visual field deterioration.
