我们旨在评估在局部麻醉下通过泪镜检查进行基于办公室的探查治疗先天性鼻泪管阻塞(CNLDO)的安全性和有效性。这项单机构研究回顾性地回顾了64名连续儿童的72只眼睛的数据(38名男孩,43只眼睛;26个女孩,29只眼睛),年龄在6至17岁之间(平均年龄:10.0±2.7)个月,怀疑有CNLDO,从2016年7月到2022年2月。这些患者在局部麻醉下接受了神经内镜检查。CNLDO的临床诊断是基于在生命的前3个月内开始的粘液排出而出现的泪液和粘稠的眼睛。泪液半月板高度增加,荧光素染料消失试验结果。72只眼睛中总共有63只定义为CNLDO,9只眼睛有其他类型的障碍物。典型CNLDO患者的干预成功率为100%(63/63眼),整个研究队列的干预成功率为97.2%(70/72眼)。此外,根据鼻泪管远端的特征,CNLDO分为五种类型。在患有CNLDO的儿科患者中,使用泪镜进行探查是安全的,并且成功率很高。这是第一项评估CNLDO患儿局部麻醉下泪镜探查的安全性和有效性的研究。
We aimed to evaluate the safety and efficacy of office-based probing with dacryoendoscopy under local anesthesia for congenital nasolacrimal duct obstruction (CNLDO). This single-institution
study retrospectively reviewed data on 72 eyes of 64 consecutive children (38 boys, 43 eyes; 26 girls, 29 eyes), aged between 6 and 17 (mean age: 10.0 ± 2.7) months with suspected CNLDO, from July 2016 to February 2022. These patients underwent probing with dacryoendoscopy under local anesthesia. CNLDO was diagnosed clinically based on the presence of epiphora and sticky eyes due to mucous discharge commencing within the first 3 months of life, increased tear meniscus height, and fluorescein dye disappearance test results. A total of 63 of the 72 eyes had narrowly defined CNLDO, and 9 eyes had other types of obstructions. The intervention success rate was 100% (63/63 eyes) for patients with typical CNLDO and 97.2% (70/72 eyes) for the entire
study cohort. Moreover, CNLDO was classified into five types based on the features of the distal end of the nasolacrimal duct. Probing with dacryoendoscopy is safe and yields a high success rate in pediatric patients with CNLDO. This is the first
study to assess the safety and efficacy of probing with dacryoendoscopy under local anesthesia in pediatric patients with CNLDO.
