Abstract
PURPOSE: To report causative organisms, visual outcomes, and associated medical conditions in endogenous endophthalmitis (EE). METHODS: Microbiological and medical reports of patients with culture-proven EE referred to Farabi Eye Hospital, Tehran, Iran, from January 2008 to January 2018 were reviewed. RESULTS: A total of 144 cases (171 eyes) were included in the present study. Candida albicans (30.6%) and Staphylococcus aureus (27.1%) were the most prevalent microbial causes. Diabetes mellitus (43.8%) and IV drug abuse (10.4%) were the leading associated systemic conditions. Age of the patients (P = 0.002) and presenting corrected distance visual acuity (CDVA) (P < 0.001) were correlated with postoperative CDVA. Patients with bilateral involvement had significantly lower mean logMAR (P = 0.002), and patients with hypopyon had significantly higher mean logMAR (P = 0.006). Eyes with gram-negative bacillus cultures had a significantly worse logMAR than eyes with gram-positive cocci (P = 0.009). CONCLUSION: Candida albicans and S. aureus were the most common causes of EE, and diabetes mellitus was the most common associated medical condition. EE is associated with poor visual outcome, especially in older patients, those with worse visual acuity at presentation, and those with positive cultures for gram-negative bacilli.
