PURPOSE: To identify risk factors for further deterioration of central visual function in advanced glaucoma eyes. DESIGN: Prospective, observational 5-year study. PARTICIPANTS: Advanced glaucoma patients with well-controlled intraocular pressure (IOP), mean deviation (MD) of the Humphrey Field Analyzer (HFA) 24-2 program ≤-20 dB and best-corrected visual acuity (BCVA) of 20/40. METHODS: The HFA 10-2 test and BCVA examination were performed every 6 months, and the HFA 24-2 test was performed every 12 months for 5 years. The Cox proportional hazards model was used to identify risk factors for deterioration of HFA 10-2 and 24-2 results and BCVA. MAIN OUTCOME MEASURES: Deterioration of HFA 10-2 results was defined by the presence of the same ≥3 points with negative total deviation slope ≤-1 dB/year at P < 0.01 on ≥3 consecutive tests, deterioration of HFA 24-2 results by an increase ≥2 in the Advanced Glaucoma Intervention Study score on ≥2 consecutive tests, and deterioration of BCVA by an increase of ≥0.2 logarithm of the minimum angle of resolution (logMAR) on ≥2 consecutive tests. RESULTS: A total of 175 eyes of 175 patients (mean age, 64.1 years; mean baseline IOP, 13.2 mmHg; mean BCVA, 0.02 logMAR; mean HFA 24-2 and 10-2 MD, -25.9 and -22.9 dB, respectively) were included. The probabilities of deterioration in HFA 10-2 and 24-2 results and BCVA were 0.269 ± 0.043 (standard error), 0.173 ± 0.031, and 0.194 ± 0.033, respectively, at 5 years. Lower BCVA at baseline (P = 0.012) was associated significantly with further deterioration of HFA 10-2 results. Better HFA 24-2 MD (P < 0.001) and use of systemic antihypertensive agents (P = 0.009) were associated significantly with further deterioration of HFA 24-2 results, and a greater β-peripapillary atrophy area-to-disc area ratio (P < 0.001), use of systemic antihypertensive agents (P = 0.025), and lower BCVA (P = 0.042) were associated significantly with further deterioration of BCVA, respectively. CONCLUSIONS: In advanced glaucoma eyes with well-controlled IOP, BCVA, β-peripapillary atrophy area-to-disc area ratio, and use of systemic antihypertensive agents were significant prognostic factors for further deterioration of central visual function.
