This study aims to report the prevalence of amblyopia risk factors in patients with congenital nasolacrimal duct obstructions.
We recruited patients who were treated for congenital nasolacrimal duct obstruction from April 2007 to December 2011 at Korea University Ansan Hospital. We evaluated visual acuity and refraction, performed strabismus test and slit-lamp examination, and assessed marginal reflex distance 1 (MRD1) to rule out amblyopia risk factors.
We examined 26 children among 115 patients. Ten patients underwent probing procedure and 16 underwent Monoka stent intubation. Nine (35%) patients showed amblyopia risk factors, which occurred in the same eye as the congenital nasolacrimal duct obstruction in 8 (89%) patients. Seven out of 9 patients had refractive error alone, and 2 patients had both refractive error and strabismus. One (11%) had anisometropia, 2 (22%) had hyperopia, and 8 (89%) had astigmatism.
Children with congenital nasolacrimal duct obstruction had a higher prevalence of amblyopia risk factors than children in the general population. Children with congenital nasolacrimal duct obstruction require special attention and treatments for refractive error. We recommend early treatment, such as probing or intubation, for congenital nasolacrimal duct obstruction.
本研究旨在报告先天性鼻泪管阻塞患者中弱视危险因素的患病率。
我们招募了2007年4月至2011年12月在韩国大学安山医院接受先天性鼻泪管阻塞治疗的患者。我们评估了视力和屈光状态，进行了斜视检查和裂隙灯检查，并评估了边缘反射距离1（MRD1）以排除弱视危险因素。
我们检查了115例患者中的26名儿童。10例患者接受了探通术，16例接受了莫诺卡支架置入术。9例（35%）患者存在弱视危险因素，其中8例（89%）患者的弱视危险因素出现在与先天性鼻泪管阻塞同侧的眼睛。9例患者中有7例仅存在屈光不正，2例同时存在屈光不正和斜视。1例（11%）有屈光参差，2例（22%）有远视，8例（89%）有散光。
先天性鼻泪管阻塞患儿中弱视危险因素的患病率高于普通人群中的儿童。先天性鼻泪管阻塞患儿需要特别关注并针对屈光不正进行治疗。我们建议对先天性鼻泪管阻塞进行早期治疗，如探通术或置入术。
