Endophthalmitis following intravitreal injections at a tertiary center: real-life data on incidence, risk factors, management strategies, and visual outcomes.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo investigate the incidence, contributing factors, management, and long-term outcomes of endophthalmitis following intravitreal injections performed in our clinic.
methodsThis retrospective study included all patients who received intravitreal bevacizumab, aflibercept, ranibizumab, or dexamethasone injections between 2019 and 2024 at four retina clinics of Ankara Bilkent City Hospital. Demographic characteristics of the patients, visual acuity, intravitreal injection etiology, comorbidities, and treatments applied were recorded. Patients who received antibiotic prophylaxis after intravitreal injections (IVI) were categorized as Group 1, while those who did not receive prophylaxis were classified as Group 2.
resultsA total of 4171 patients and 21,339 intravitreal injections were evaluated. Of the participants, 47.2% were female and 52.8% were male, with a mean age of 66.3 ± 10.3 years (range: 40-98). Group 1 included 13,121 injections (61%), while Group 2 had 8,218 injections (39%). Endophthalmitis was observed in 13 patients (3.0 per 1000 patients-8.1 per 10,000 injections). Patients who developed endophthalmitis had an average of 6.1 ± 4.1 prior injections (range: 2-16), and the mean time to presentation after the last injection was 7.6 ± 3.4 days (range: 2-14). Endophthalmitis cases were distributed as 7 in Group 1 (5.3 per 10,000) and 6 in Group 2 (4.4 per 10,000). The endophthalmitis rate in Group 1 was not statistically significantly different from Group 2 (p > 0.05). All patients received vitreous taps and intravitreal vancomycin-ceftazidime injections at initial presentation. Eleven patients (85%) underwent a pars plana vitrectomy within 24 h. The mean follow-up period was 32 ± 20 months, and any case did not require evisceration surgery.
conclusionEarly surgical intervention in cases of endophthalmitis is the most critical approach for preserving the eye and achieving visual rehabilitation. Notably, endophthalmitis was more common in people who got intravitreal bevacizumab or dexamethasone injections, and antibiotic prophylaxis did not appear to reduce the risk of its occurrence.
