Previous studies have reported conflicting results on the influence of seasons on post-cataract surgery endophthalmitis incidences. This study aimed to investigate the seasonality associated with the incidence of postoperative endophthalmitis, and to evaluate its association with climate variables in South Korea.
South Korea.
Retrospective cohort study.
The postoperative endophthalmitis incidences were identified using the Health Insurance Review and Assessment Service claim data from July 2014 to June 2017. The monthly climate data were obtained from the Korea Meteorological Administration. The incidences of endophthalmitis were analyzed by the month of the year, and by the season. The association between postoperative endophthalmitis and the climatic variables, including mean temperature, relative humidity, precipitation, and hours of sunshine, was investigated.
The incidences were the highest in July, and they were the most prevalent during the summer months, although fewer cataract surgeries were performed in the summer months than during the rest of the year. The postoperative endophthalmitis incidences tended to increase with increasing relative humidity and increasing precipitation.
The incidences of post-cataract surgery endophthalmitis peaked during the hot and humid months. Understanding the seasonal and climatic influences on postoperative infection might help in risk stratification and outcome improvisation after the cataract surgery is performed.
先前的研究报告了季节对白内障手术后眼内炎发生率的影响结果相互矛盾。本研究旨在调查与术后眼内炎发病率相关的季节性，并评估其与韩国气候变量的关系。
韩国。
回顾性队列研究。
使用 2014 年 7 月至 2017 年 6 月的健康保险审查和评估服务索赔数据，确定术后眼内炎的发生率。每月的气候数据来自韩国气象局。通过年度月份和季节分析眼内炎的发生率。调查了术后眼内炎与包括平均温度、相对湿度、降水和日照时间在内的气候变量之间的关系。
7 月的发生率最高，尽管夏季进行的白内障手术比其他时间少，但夏季的发病率最高。术后眼内炎的发生率随着相对湿度和降水量的增加而增加。
白内障手术后眼内炎的发生率在炎热潮湿的月份达到高峰。了解术后感染的季节性和气候影响可能有助于在白内障手术后进行风险分层和改善结果。
