To evaluate the prevalence of retinal pigment epithelium (RPE) tears associated with anti-VEGF therapy and its relation with retinal pigment epithelial detachment (PED).
A total of 226 patients with exudative age-related macular degeneration treated with intravitreal anti-VEGF were included retrospectively in the study. The presence of RPE tears; the effect of the presence, height, and duration of PED on the rate of RPE tears; and change in visual acuity during follow-up were recorded.
Among 226 study patients, 28 (12.3%) had RPE tears. The RPE tear rate was significantly higher in patients with vascularized PED (vPED) than in those without PED (19.7% vs. 2.1%; P < 0.001). The change in visual acuity after the formation of RPE tear was not statistically significant (on logMAR scale: 0.92 ± 0.49 initially, 0.89 ± 0.41 after the RPE tear, 0.96 ± 0.45 at the last follow-up; P = 0.613). Pigment epithelial detachment height >580 μm (odds ratio = 69.4; 95% confidence interval = 16.7–288.1) and PED duration ≤4.5 months (odds ratio = 166.7; 95% confidence interval = 15.2–1000) were found to be significant risk factors for RPE tear formation.
The RPE tears are not infrequent among eyes treated with intravitreal anti-VEGFs. The presence, increased height, and shorter duration of vPED are potential risk factors for RPE tears associated with anti-VEGF therapy.
This retrospective study examined the prevalence of retinal pigment epithelium tears associated with anti–vascular endothelial growth factor therapy (intravitreal ranibizumab and bevacizumab) in eyes with and vascularized pigment epithelial detachment whether presence, duration, and height of pigment epithelial detachment provide an estimate of the risk of retinal pigment epithelium tears.
