Abstract: Objective：To analyze the incidence, clinical characteristics and visual outcomes of postoperative endophthalmitis of cataract. Methods: Reviewed all the 15 electronic surgical records of cataract surgery during the last 12 years in Peking University First Hospital and summarized the incidence, onset time, symptoms, clinical signs and pathogenic characteristics of endophthalmitis. Analyzed the laws of vision changes and the related factors of visual outcomes. The data were analyzed with SPSS 14.0. Results: The overall rate of endophthalmitis was 0.17%, while most of the patients had serious symptoms and low vision. The onset time of the disease was 23.8 days on average, while that of the acute cases was 6 days. The positive rate of bacterial examination was 60% and all of the results were G+ (77% was Staphylococcus epidermidis). The visual acuity after treatment was improved to varying degrees. Our research had revealed that the factors related to the visual outcome included postsurgery visual acuity (r=0.746，P<0.01), presenting visual acuity at the onset of endophthalmitis (r=0.667，P<0.01), posterior capsular rupture occurrence (P<0.05) and ocular irritation symptoms (P<0.05). Conclusion: Better visual outcome of endophthalmitis after cataract surgery is correlated with positive and correct treatment. The vision and signs of the patients are useful to predict the visual outcomes.
