AIM To study the clinical features, microbial spectrum, associated factors and prognosis of endogenous endophthalmitis (EE) in a group of Chinese patients. METHODS The medical records from 32 eyes of 29 patients diagnosed with EE in Peking Union Medical College Hospital from January 2009 to October 2019 were reviewed. RESULTS The initial visual acuity (VA) of 30 eyes in this study was worse than 20/400. Twenty-three eyes were diagnosed with fungal endophthalmitis and nine with bacterial endophthalmitis. The most common fungal and bacterial isolates were Candida and Klebsiella pneumoniae, respectively. Several rare fungi and bacteria species were also isolated from our patients, including Cryptococcus, Paecilomyces, Brucella, and Bacillus licheniformis. The leading risk factor for EE was diabetes. The most common extraocular infection locus was genitourinary tract. Vitrectomy was performed on twenty-nine eyes. Eight eyes achieved final VA of 20/400 or better. EE caused by Candida had a better prognosis. CONCLUSION The visual outcome of EE is based on pathogens and prompt intervention. Early vitrectomy and antimicrobial treatment are beneficial for EE.
