Global reported endophthalmitis risk following intravitreal injections of anti-VEGF: a literature review and analysis.

ABSTRACT: PURPOSE: To report on endophthalmitis occurrence and associated risk factors following the intravitreal injection of anti-VEGF agents based on a review of published literature. MATERIALS AND METHODS: A Medline search was performed using the terms "bevacizumab" and "ranibizumab". A total of 534 English-language articles of varying design and published from 2006 to November 2013 were analyzed for endophthalmitis occurrence and contributing perioperative factors. RESULTS: A total of 445,503 injections were counted. There were 103 cases of postinjection endophthalmitis in 176,124 injections (0.058%) with bevacizumab (Avastin) versus 79 cases in 269,379 injections (0.029%) with ranibizumab (Lucentis). This difference was due to a significantly higher occurrence of culture-negative endophthalmitis associated with bevacizumab injections. Culture-positive risk was not statistically different between the two drugs. The reported use of postinjection topical antibiotics increased the risk of culture-positive endophthalmitis. No association was found with the use of povidone iodine, a lid speculum, a mask, or an operating room. Streptococcus spp. were the most prevalent causative organism, accounting for nine of 54 (17%) of all culture-positive cases. CONCLUSION: Reported postinjection endophthalmitis occurred significantly more in patients treated with bevacizumab than those treated with ranibizumab. However, culture-positive occurrence was similar. Despite the potential for contamination at the time of drug compounding, bevacizumab does not appear to confer a higher risk of culture-positive endophthalmitis than ranibizumab. This study also suggests antibiotic use may increase endophthalmitis occurrence.

Project description:PurposeIntravitreal (IVT) injections of the anti-vascular endothelial growth factor (VEGF) agents aflibercept, bevacizumab, and ranibizumab are commonly prescribed to treat neovascular age-related macular degeneration (nAMD). Studies comparing inflammation rates in large populations of patients receiving these agents and the treatment of ocular inflammation post-IVT anti-VEGF injections are scarce. In this study, we compared rates of endophthalmitis claims (sterile and infectious) following IVT anti-VEGF injections to determine the risk factors associated with developing endophthalmitis, and examined the claims for subsequent treatment.Patients and methodsThis retrospective cohort study of USA claims data examined the risk of developing endophthalmitis following IVT injection of aflibercept, bevacizumab, or ranibizumab in patients with nAMD between 11/18/2011 and 5/31/2013. The primary study outcome was occurrence of endophthalmitis within 30 days of a claim for an IVT anti-VEGF injection. Endophthalmitis rates were calculated separately for aflibercept, bevacizumab, and ranibizumab, followed by pairwise comparisons of endophthalmitis frequencies among the 3 treatments.ResultsThis analysis included 818,558 injections from 156,594 patients with nAMD. The rates (% [n/N]) of endophthalmitis following aflibercept, bevacizumab, and ranibizumab IVT injections were 0.100% (136/135,973), 0.056% (268/481,572), and 0.047% (94/201,013), respectively. In a multivariate analysis, aflibercept was associated with a significantly higher risk of endophthalmitis vs ranibizumab (adjusted odds ratio, 2.19; 95% CI: 1.68-2.85; P<0.0001). The risk of endophthalmitis was similar for bevacizumab and ranibizumab. Within 14 days after endophthalmitis, 38.6% of cases received injectable antibiotics, 15.3% received injectable steroids, and 30.3% underwent vitrectomy.ConclusionThe rate of endophthalmitis was very low, but higher following IVT injection with aflibercept compared with both bevacizumab and ranibizumab in patients with nAMD.

Project description:PurposeRoutine use of face masks for patients and physicians during intravitreal anti-vascular endothelial growth factor (VEGF) injections has increased with the emergence of the coronavirus disease 2019 pandemic. This study evaluates the impact of universal face mask use on rates and outcomes of post-injection endophthalmitis (PIE).DesignRetrospective, multicenter, comparative cohort study.ParticipantsEyes receiving intravitreal anti-VEGF injections from October 1, 2019, to July 31, 2020, at 12 centers.MethodsCases were divided into a "no face mask" group if no face masks were worn by the physician or patient during intravitreal injections or a "universal face mask" group if face masks were worn by the physician, ancillary staff, and patient during intravitreal injections.Main outcome measuresRate of endophthalmitis, microbial spectrum, and visual acuity (VA).ResultsOf 505 968 intravitreal injections administered in 110 547 eyes, 85 of 294 514 (0.0289%; 1 in 3464 injections) cases of presumed endophthalmitis occurred in the "no face mask" group, and 45 of 211 454 (0.0213%; 1 in 4699) cases occurred in the "universal face mask" group (odds ratio [OR], 0.74; 95% confidence interval [CI], 0.51-1.18; P = 0.097). In the "no face mask" group, there were 27 cases (0.0092%; 1 in 10 908 injections) of culture-positive endophthalmitis compared with 9 cases (0.004%; 1 in 23 494) in the "universal face mask" group (OR, 0.46; 95% CI, 0.22-0.99; P = 0.041). Three cases of oral flora-associated endophthalmitis occurred in the "no face mask" group (0.001%; 1 in 98 171 injections) compared with 1 (0.0005%; 1 in 211 454) in the "universal face mask" group (P = 0.645). Patients presented a mean (range) 4.9 (1-30) days after the causative injection, and mean logarithm of the minimum angle of resolution (logMAR) VA at endophthalmitis presentation was 2.04 (~20/2200) for "no face mask" group compared with 1.65 (~20/900) for the "universal face mask" group (P = 0.022), although no difference was observed 3 months after treatment (P = 0.764).ConclusionsIn a large, multicenter, retrospective study, physician and patient face mask use during intravitreal anti-VEGF injections did not alter the risk of presumed acute-onset bacterial endophthalmitis, but there was a reduced rate of culture-positive endophthalmitis. Three months after presentation, there was no difference in VA between the groups.
