Abstract

Purpose: To report the reasons for treatment discontinuation within 5 years in patients receiving intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy for neovascular age-related macular degeneration (nAMD).

Methods: A retrospective case-notes review of patients commenced on anti-VEGF for nAMD who failed to complete 5 years of follow-up was undertaken. The reasons for treatment discontinuation, baseline age, baseline visual acuity (VA) in Early Treatment Diabetic Retinopathy Study (ETDRS) letters, and the VA change at the last follow-up were recorded. Age-specific all-cause mortality was calculated for deceased patients.

Results: Of the 1177 patients, 551 patients (46.8%) failed to complete the 5-year follow-up. The reasons for treatment discontinuation were death (251), early discharge due to stable disease (110), further treatment deemed futile (100), failure to attend (15), ill health (14), patient choice (7), and transfer of care (1). In 53 patients, no reason was documented. The mean baseline age of those who completed the 5-year follow-up (77.4 ± 7.8 years, 95% confidence interval (CI): 76.8-77.9) was significantly lower than those who discontinued the treatment for any reason (82 ± 7.7 years, 95% CI: 81.4-82.6) (P < 0.0001). Survival analysis showed that baseline VA was not a factor in treatment discontinuation; however, visual stability (±5 letters from baseline) was associated with treatment continuation. The age-specific all-cause mortality in deceased patients was lower than that in the general population.

Conclusion: At 5 years, only 53% of patients remained in active care, and death was the most common reason for treatment discontinuation. Lower baseline age and VA stability during therapy were associated with treatment continuation.
