方法：研究在我院进行白内障手术患者1 900例1 900眼，根据术后有无发生眼内炎分为感染组与对照组。分析患者各临床指标对白内障术后眼内炎发生的影响，采用单因素检验及多因素Logistic回归分析相关危险因素。另外，对所有眼内炎患者进行玻璃体切割术治疗，观察手术对患者预后的影响。

结果：单因素分析显示，年龄、高血压、糖尿病、玻璃体溢出、手术时间、普通手术室内进行手术以及麻醉剂开启后未在规定时间内使用等均是导致白内障术后眼内炎发生的危险因素(P<0.05)； 多因素Logistic回归分析显示，年龄≥70岁、高血压、糖尿病、玻璃体溢出、手术时间≥10 min、普通手术室进行手术以及麻醉剂开启后未在规定时间内使用均是导致白内障术后眼内炎发生的独立危险因素(P<0.05)。经玻璃体切割术治疗后，患者视力得到明显的提高(P<0.05)。

结论：年龄、高血压、糖尿病、玻璃体溢出、手术时间、普通手术室进行手术以及麻醉剂开启后未在规定时间内使用等因素均是导致白内障术后眼内炎发生的危险因素。而通过玻璃体切割术治疗，能够有效改善患者的视力。

METHODS: One thousand nine hundred patients(1 900 eyes)of receiving cataract surgery in our hospital were selected and divided into infection group and control group according to the incidence of endophthalmitis. The influence of clinical index in the endophthalmitis after cataract surgery as well as related risk factors based on single factor and multi-factor Logistic regression was analyzed. All patients with endophthalmitis were received vitrectomy, and the prognosis of endophthalmitis after vitrectomy was observed.

RESULTS: Based on single factor analysis, the risk factors of endophthalmitis after cataract surgery including age, hypertension, diabetes mellitus, vitreous loss, operation time, common operating room and nonuse of anesthetics in the required time lead to the ocurrence of endophthalmitis after cataract surgery(P<0.05). Based on multi-factor Logistic regression, the independent risk factors of endophthalmitis after cataract surgery included age(≥70 years old), hypertension, diabetes mellitus, vitreous loss, operation time(≥10min), common operating room and nonuse of anesthetics in the required time(P<0.05). After vitrectomy, the vision of patients was significantly improved(P<0.05).

CONCLUSION: The risk factors of endophthalmitis after cataract surgery include age, hypertension, diabetes mellitus, vitreous loss, operation time, common operating room and nonuse of anesthetics in the required time. Vitrectomy can significantly improve the vision of patients.
