CLOSTRIDIAL ENDOPHTHALMITIS: CLINICAL PRESENTATIONS, MANAGEMENT OUTCOMES, AND REVIEW OF LITERATURE.

To describe the clinical presentations, diagnosis and management outcomes of clostridial endophthalmitis, and a review of the previous literature. Retrospective, interventional case series from January 2005 to March 2018 and a literature review. The study included seven eyes of seven patients with culture-proven Clostridium sp. endophthalmitis. Identification of Clostridium sp. was confirmed by the VITEK 2 system using the ANC card. When VITEK failed to identify the organism, MALDI-TOF was used. Data regarding demography, clinical presentations, interventions received, and final visual and anatomical outcomes were noted. mean age of the patients was 28.28 ± 22.35 years (median 21 years). By the etiology of infection, 5 (75%) eyes were post-open-globe injury, 1 (12.5%) was post-trabeculectomy, and 1 (12.5%) was postintravitreal injection. The mean follow-up was 9.71 ± 12.03 months, median 6 months. Two samples were positive for Clostridium perfringens, one each for C. subterminale, C. difficile, and C. tertium, and two were unidentified clostridial species. Favorable anatomical outcome was seen in 3/7 eyes (42.85%). Favorable functional outcome was seen in 2/7 eyes (28.57%). These were comparable with the outcomes of the pooled pre-existing literature. There was a trend toward better functional and anatomical outcomes and lesser evisceration/enucleation rates with vitrectomy instead of a vitreous tap, although not statistically significant. All cases showed susceptibility to empirically used intravitreal antibiotic vancomycin. Commonest setting of clostridial endophthalmitis is post-open-globe injury. Despite treatment with appropriate antibiotics, the visual and anatomical outcome is unsatisfactory because of high organism virulence. Early vitrectomy may allow for globe salvage and potential vision.
