abstract

  • OBJECTIVE:To evaluate the outcomes and complications of bilateral same-day intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections. METHODS:This is a single-center, retrospective study that included 524 eyes of 262 patients who received concomitant bilateral intravitreal anti-VEGF injections in 2016 at St. Michael's Hospital, Toronto. If any of the patients were receiving simultaneous bilateral injections on a regular basis prior to 2016, data pertaining to previous injections were also reviewed. Everyone received bevacizumab, ranibizumab, or aflibercept in an office setting. RESULTS:A total of 9,798 intravitreal anti-VEGF injections (4,899 bilateral injection sessions) were performed in 524 eyes of 262 patients. The average number of bilateral injection sessions per patient was 18.7 ± 14.1. Ranibizumab was the most commonly used anti-VEGF drug (83.8%). The incidence of endophthalmitis was 0.01%, and there were 2 episodes of acute intraocular inflammation among the 9,798 injections (0.02%). All 3 cases occurred after treatment with ranibizumab. There were 2 deaths (0.76%) due to nonvascular causes but no vascular related systemic adverse events were reported. CONCLUSIONS:Same-day bilateral intravitreal anti-VEGF injections present a low rate of complications and are well tolerated by patients. This safe practice may reduce the burden on the health-care system and on the patients.
