title: Incidence of Retinal Pigment Epithelial Tears and Associated Risk Factors After Treatment of Age-Related Macular Degeneration with Intravitreal Anti-VEGF Injections.
abstract: OBJECTIVE
  To study the incidence and risk factors for retinal pigment epithelium tears following intravitreal anti-vascular endothelial growth factor (VEGF) injections.
  
  
  METHODS
  Retrospective longitudinal study. 4027 intravitreal anti-VEGF injections in 628 patients (676 eyes) for choroidal neovascularisation associated with age related macular degeneration in a period of 18 months were studied.
  
  
  RESULTS
  Seventeen patients (mean age 83.95±5.84) developed retinal pigment epithelium tears. The incidence rate was 0.4%. Fibrovascular pigment epithelium detachment (PED) was previously observed in all cases. In 88 % (15/17) of AMD patients that had a RPE tear, PED height was found to be less than 400 microns at presentation. In 5 of 7 patients with RPE tear grade <4, continuing of anti-VEGF treatment resulted to improvement of visual acuity.
  
  
  CONCLUSIONS
  Critical risk factors for RPE tears are presence of PED as well as advanced age. Visual improvement appears to depend more on the extent and location of the RPE tear and less on the PED height.
