摘要

背景:弱视在发展中国家的患病率和负担可能被低估了,并且对西非弱视的模式知之甚少。目的:了解某三级医院眼科门诊2年内屈光不正儿童弱视的相对频率和类型。方法:2012年1月至2013年12月在尼日利亚伊巴丹大学学院医院眼科诊所进行横断面研究。在此期间,我们检索了屈光不正儿童的病例记录,并记录了包括社会人口统计数据、视力和矫正视力在内的信息。弱视定义为最佳矫正视力低于6/9或在没有任何可解释视力障碍的眼部病理的情况下,双眼之间的Snellen图表线差≥2。结果:共有250例屈光不正患者被纳入研究。224例(89.6%)儿童视力矫正至6/9及以上,26例(10.4%)儿童弱视。26例弱视患儿中,双眼弱视21例(80.8%),等屈光性弱视占多数(65.4%)。47只弱视眼中,中度弱视36只(76.6%)眼,重度弱视11只(23.4%)眼。结论:本研究中弱视的相对发生率较高,建议对所有儿童进行学前眼科检查,确保弱视的早期发现和管理,从而减轻我国人群弱视的负担。

Refractive Amblyopia among children in Ibadan: the need for amblyopia screening programmes.

Background: The prevalence and burden of amblyopia in developing countries is probably underestimated, and little is known about the pattern of amblyopia in West Africa.

Aim: To determine the relative frequency and types of amblyopia among children with refractive errors seen in the eye clinic of a tertiary hospital over a 2 year period.

Methods: A cross-sectional study conducted at the eye clinic of the University College Hospital, Ibadan, Nigeria between January 2012 and December 2013. Case notes of children with refractive errors seen during this period were retrieved and information including socio-demographic data, presenting visual acuity and visual acuity with correction were recorded. Amblyopia was defined as best corrected visual acuity worse than 6/9 or a difference of ≥ 2 Snellen chart lines between both eyes in the absence of any ocular pathology that could explain the visual impairment.

Results: A total of 250 eligible patients who had refractive errors were included in the study. Visual acuity was corrected to 6/9 or better in 224 (89.6%) children while 26 (10.4%) of them had amblyopia. Among the 26 children with amblyopia, 21 (80.8%) children had amblyopia in both eyes and majority (65.4%) had iso-ametropic amblyopia. Of the 47 amblyopic eyes, 36 (76.6%) eyes had moderate amblyopia while 11 (23.4%) eyes had severe amblyopia.

Conclusion: There is a high relative frequency of amblyopia in this study and we recommend preschool eye examinations for all children to ensure early detection and management of amblyopia, thereby reducing the burden of amblyopia in our populace.
