Effect of Lidocaine Gel Anesthesia on Endophthalmitis Rates Following Intravitreal Injection OPHTHALMIC SURGERY LASERS & IMAGING Lad, E. M., Maltenfort, M. G., Leng, T. 2012; 43 (2): 115-120

Abstract

To determine whether the use of lidocaine gel before application of povidone-iodine affects endophthalmitis rates following intravitreal injections.Retrospective consecutive case series of all intravitreal injections and post-intravitreal injection endophthalmitis cases at one institution from 2000 to 2009. A review of medical records of post-intravitreal injection endophthalmitis cases was performed to determine whether lidocaine gel was applied prior to povidone-iodine antisepsis and to analyze the clinical course and outcomes.A total of 8,802 intravitreal injections were administered during the study period. When no lidocaine gel was used prior to povidone-iodine antisepsis, four cases of endophthalmitis following 4,120 intravitreal injections (0.097%) were recorded. When 2% lidocaine gel was applied before povidone-iodine, four cases of endophthalmitis following 4,682 intravitreal injections (0.085%) were observed (P = 1.00, odds ratio = 1.12).The use of lidocaine gel prior to povidone-iodine antisepsis did not significantly alter post-intravitreal injection endophthalmitis rates.
