Outcomes of Eyes Lost to Follow-up with Neovascular Age-Related Macular Degeneration Receiving Intravitreal Anti-Vascular Endothelial Growth Factor.
PURPOSE: To determine outcomes of eyes with neovascular age-related macular degeneration (nAMD) receiving intravitreal anti-vascular endothelial growth factor (VEGF) injections who return after a period of being lost to follow-up (LTFU). DESIGN: Retrospective, cross-sectional study. PARTICIPANTS: Eyes that received intravitreal bevacizumab, ranibizumab, or aflibercept for nAMD and were LTFU for >6 months. METHODS: Comparison of visual outcomes and structural parameters at the visit before LTFU, return visit, and final visit. MAIN OUTCOME MEASURES: Logarithm of the minimum angle of resolution (logMAR) visual acuity (VA), presence of subretinal fluid and intraretinal fluid, and central foveal thickness (CFT) by OCT. RESULTS: A total of 93 eyes of 77 patients were included in the analysis. Mean duration from date of LTFU to return was 346 (±122) days. Overall, 53.7% of patients had worse median logMAR VA by the final visit. Median logMAR VA worsened from 0.60 (0.40-2.00) (Snellen 20/80 [20/50-20/2000]) at the visit before LTFU to 1.00 (0.48-2.00) (20/200 [20/60-20/2000]) at the return visit (P < 0.001). Median logMAR VA remained worse at 6- and 12-months after return from LTFU: 1.00 (0.48-2.00) (20/200 [20/60-20/2000]) (P = 0.001) and 0.70 (0.44-1.30) (20/100 [20/55-20/399]) (P = 0.004), respectively. Despite a mean of 383 (±270) days of follow-up after returning and 5.0 (±5.1) additional injections, the median logMAR VA remained worse at 1.00 (0.54-2.00) (20/200 [20/70-20/2000]) at the final visit compared with the visit before LTFU (P < 0.001). There was greater worsening in mean logMAR VA from the visit before LTFU to the final visit in eyes that received bevacizumab (0.32) and ranibizumab (0.28) compared with aflibercept (P = 0.003, P = 0.04, and P = 0.03, respectively). Mean CFT increased from 201 (±106) μm at the visit before LTFU to 240 (±147) μm at return (P = 0.004). By the final visit, the mean CFT had decreased to 183 (±101) μm, which was not significantly different from the visit before LTFU (P = 0.10). CONCLUSIONS: Eyes with nAMD receiving intravitreal anti-VEGF that were LTFU experience significant VA decline at the return visit that persists on final follow-up despite normalization of CFT.
