摘要
目的评价卡诺ECWA眼科医院白内障术后眼内炎的发生率和视力结局。研究设计回顾性图表回顾。方法回顾性分析了2021年1月至2023年12月期间进行的9782例白内障手术，包括白内障囊外摘除、小切口白内障手术和超声乳化手术。收集的数据包括患者人口统计学、手术细节、眼内炎发病时间、视力结果和微生物学结果。描述性统计用于总结研究结果，并使用Wilson评分区间计算发生率的置信区间。卡方检验用于评估手术技术与视力结果之间的关系，并使用逻辑回归来确定视力改善的预测因素。显著性阈值p <；采用0.05，确保严格评估手术技术、患者特征和视力恢复之间的关系。结果术后眼内炎总发生率为0.17% (17/ 9782；95% ci: 0.10%-0.26%)。发病率最高的是2022年（0.22%,8/3,625）。治疗后，52.9%的患者视力改善，23.5%的患者无变化，23.5%的患者视力恶化。早期感染（OR: 0.72, p = 0.01）和由经验丰富的全职工作人员进行手术（OR: 2.50, p = 0.03）显著预示着更好的预后。手术类型与视力结果无统计学意义相关（p = 0.12）。在玻璃体培养中未检测到微生物生长，可能是由于先前使用抗生素所致。ECWA眼科医院术后眼内炎的发生率与全球基准一致，强调了坚持预防策略、手术预防措施和强有力的培训计划的重要性。视力结果受早期诊断和外科医生专业知识的显著影响。
Postoperative endophthalmitis following cataract surgery: Incidence and visual outcomes at ECWA Eye Hospital, Kano, Nigeria
Purpose
To evaluate the incidence and visual outcomes of postoperative endophthalmitis following cataract surgery at ECWA Eye Hospital, Kano.
Study design
Retrospective chart review.
Methods
This retrospective study reviewed 9,782 cataract surgeries performed between January 2021 and December 2023, encompassing extracapsular cataract extraction, small-incision cataract surgery, and phacoemulsification. Data collected included patient demographics, surgical details, time to onset of endophthalmitis, visual acuity outcomes, and microbiological findings. Descriptive statistics were used to summarize the findings, and incidence rates were calculated with confidence intervals using the Wilson Score Interval. Chi-Square tests were used to assess associations between surgical techniques and visual outcomes, and logistic regression to identify predictors of improved visual acuity. A significance threshold of p < 0.05 was applied, ensuring rigorous evaluation of the relationships between surgical techniques, patient characteristics, and visual recovery.
Results
The overall incidence of postoperative endophthalmitis was 0.17% (17/9,782; 95% CI: 0.10%–0.26%). The highest incidence was recorded in 2022 (0.22%, 8/3,625). Visual acuity improved in 52.9% of patients post-treatment, while 23.5% showed no change, and 23.5% experienced worsened outcomes. Earlier onset of infection (OR: 0.72, p = 0.01) and surgeries performed by experienced full-time staff (OR: 2.50, p = 0.03) significantly predicted better outcomes. No statistically significant association was observed between procedure type and visual outcomes (p = 0.12). No microbial growth was detected in vitreous cultures, likely due to prior antibiotic use.
Conclusion
The incidence of postoperative endophthalmitis at ECWA Eye Hospital aligns with global benchmarks, highlighting the critical importance of adhering to preventive strategies, surgical precautions, and robust training programs. Visual outcomes are significantly influenced by early diagnosis and surgeon expertise.
