Retinal Pigment Epithelium Tears after Anti-Vascular Endothelial Growth Factor Therapy for Neovascular Age-Related Macular Degeneration

Purpose: The aim of this study was to assess the visual prognostic factors of retinal pigment epithelium (RPE) tears and describe their clinical features. Methods: The medical records of treatment-naive neovascular age-related macular degeneration patients who received intravitreal anti-vascular endothelial growth factor (VEGF) injections were retrospectively reviewed. Results: The incidence of RPE tears was 1.36% (10 out of 733 eyes). The type of anti-VEGF agent administered did not affect the incidence (p = 0.985). The median best-corrected visual acuity (BCVA) of 10 patients decreased after an RPE tear (0.4–0.6 logarithm of the minimum angle of resolution [logMAR]); however, subsequent injections restored the BCVA to a level similar to that before the RPE tear (0.4 logMAR, p = 0.436). Central macular thickness improved significantly during the study (794.4–491.9 μm, p = 0.013). The final BCVA was positively correlated with the BCVA before and immediately after the RPE tear (p = 0.025 and 0.002, respectively) and was weakly correlated with foveal involvement of the RPE tear (p = 0.061). Conclusion: The incidence of RPE tears did not differ according to the type of anti-VEGF agent. The final BCVA was proportional to the BCVA before and after RPE tears. Continuous treatment with anti-VEGF after the occurrence of RPE tears can benefit the final visual acuity and macular anatomy.
