Background & ObjectivesGeographical variations are known to influence different aspects of endophthalmitis. We report the epidemiological, clinical and microbiological profile of patients with infectious endophthalmitis presented to a tertiary eye care centre in Odisha, India, and compare the results with published reports from other parts of India.MethodsRetrospective review of medical records of 107 patients, seen between December 2006 and January 2009 was done. All patients had undergone parsplana vitrectomy with intraocular antibiotics and the management was based on microbiological analysis of the vitreous fluid.ResultsForty six (43.0%) patients had post-operative (PO), 43 had post-traumatic (PT) and 18 (16.8%) had endogenous (EG) endophthalmitis. Males were predominant in all three types of endophthalmitis. Significantly younger individuals constituted PT group. While culture established microbial diagnosis in 45 patients (42%), direct microscopy was positive in 38 patients (35.5%). Fungal aetiology was found in 13 patients (PO-7, PT-4, EG-2) and bacteria accounted for 32. Similar to studies from north, central and south India, fungi and Gram-negative bacteria accounted for a large number of PO endophthalmitis cases. Two PT patients had polymicrobial infection. All Gram-positive bacteria were susceptible to vancomycin. Susceptibility to ceftazidime was variable among the Gram-negative bacteria. Best corrected visual acuity (BCVA) at presentation was less than 20/200 in majority (93%) of the patients. While the treatment outcome was variable in fungal and sterile endophthalmitis, the BCVA was either unchanged or improved in 100 per cent of bacterial endophthalmitis patients.Interpretation & ConclusionsThe spectrum of infection and outcome of infectious endophthalmitis in Odisha was similar to other parts of the country. Fungi and bacteria were involved in all three types of endophthalmitis. Empirical use of standard intravitreal therapy is recommended while emphasizing on vitreous biopsy for culture and sensitivity whenever possible.
