Purpose:To investigate the factors associated with maximum visual improvement (peak vision) gain and the risk factors of peak vision loss and multiple recurrences in myopic macular neovascularization undergoing antivascular endothelial growth factor therapy.Methods:Retrospective study of 310 eyes with active myopic macular neovascularization and median follow-up of 3.5 years. We defined peak vision gain as the maximum best-corrected visual acuity value reached under treatment and peak vision loss as best-corrected visual acuity never scoring as peak vision. We used multiple-event Prentice, Williams, and Peterson models to compute recurrences' incidence and Cox regression to identify risk factors for peak vision gain, peak vision loss, and multiple recurrences.Results:Eyes with worse baseline best-corrected visual acuity {hazard ratio (HR) = 2.59 (95% confidence interval [CI]: 1.63-4.11) for 0.1 logMAR increase, P < 0.001} had higher chance to achieve peak vision. Peak vision was lost in 162 eyes (52%). Older age (HR = 1.22 [95% CI: 1.02-1.43] for 10-year increase, P = 0.02) and recurrences (HR = 1.10 [95% CI: 1.01-1.22] for event, P = 0.04) predicted nonsustained peak vision. Older age (HR = 1.13 [95% CI: 1.04-1.27] for 10-year increase, P = 0.006), larger myopic macular neovascularization (HR = 1.06 [95% CI: 1.01-1.13] for 1-mm2increase, P = 0.04), and juxtafoveal location (HR = 1.88 [95% CI: 1.28-2.77] vs. extrafoveal, P = 0.001) predicted multiple recurrences.Conclusion:Myopic macular neovascularization eyes lose vision mainly because of multiple recurrences. Patients at risk for recurrences should undergo more attentive monitoring to avoid vision loss.

Abstract

Purpose:To investigate the factors associated with maximum visual improvement (peak vision) gain and the risk factors of peak vision loss and multiple recurrences in myopic macular neovascularization undergoing antivascular endothelial growth factor therapy.Methods:Retrospective study of 310 eyes with active myopic macular neovascularization and median follow-up of 3.5 years. We defined peak vision gain as the maximum best-corrected visual acuity value reached under treatment and peak vision loss as best-corrected visual acuity never scoring as peak vision. We used multiple-event Prentice, Williams, and Peterson models to compute recurrences' incidence and Cox regression to identify risk factors for peak vision gain, peak vision loss, and multiple recurrences.Results:Eyes with worse baseline best-corrected visual acuity {hazard ratio (HR) = 2.59 (95% confidence interval [CI]: 1.63-4.11) for 0.1 logMAR increase, P < 0.001} had higher chance to achieve peak vision. Peak vision was lost in 162 eyes (52%). Older age (HR = 1.22 [95% CI: 1.02-1.43] for 10-year increase, P = 0.02) and recurrences (HR = 1.10 [95% CI: 1.01-1.22] for event, P = 0.04) predicted nonsustained peak vision. Older age (HR = 1.13 [95% CI: 1.04-1.27] for 10-year increase, P = 0.006), larger myopic macular neovascularization (HR = 1.06 [95% CI: 1.01-1.13] for 1-mm2increase, P = 0.04), and juxtafoveal location (HR = 1.88 [95% CI: 1.28-2.77] vs. extrafoveal, P = 0.001) predicted multiple recurrences.Conclusion:Myopic macular neovascularization eyes lose vision mainly because of multiple recurrences. Patients at risk for recurrences should undergo more attentive monitoring to avoid vision loss.
