PURPOSE: To investigate the treatment of severe bacterial endophthalmitis. METHODS:The curative effects of vitrectomy after intravitreal antibiotics and steroids (IVAS)for the treatment of 23 patients with bacterial endophthalmitis (group I)and vitrectomy and IVA at the same time for the treatment of 28 patients with bacterial endopbthalmitis (group I)were analyzed retrospectively. RESULTS: The rate of curative effects of two groups were similar,while the marked curative effects in group I (47.8% )was significantly higher than that of the group I (17.9%). The average period of eliminating infiamation of group I was longer than that of group I , and the incidence of postoperative retinal detachment of group Ⅱ was 3 times more than that of group I . CONCLUSION :It was indicated that vitrectomy after IVAS may increase the security of vitrectomy and the curative effects of severe bacterial ndophthalmitis.
In recent years，there are more and more cases of retinal infectious diseases in China，however，the diagnosis and management of those patients are still big challenges for our ophthalmic clinicians. It is our top priority to improve their capacity of early diagnosis for those diseases. We need to know the relationship between retinal infectious diseases and systemic infections, their predisposing factors. We also need to be familiar with the typical as well as atypical clinical features of those diseases. Vitreoretinal surgery already becomes a powerful tool to make diagnosis of retinal infectious diseases now；we need to make full use of this tool combined with modern technologies of microbiology, cytology, immunology and molecular biology to provide objective scientific evidences for the early diagnosis of retinal infectious diseases.
