To study the effect of cycloplegia on optical biometry parameters in pediatric eyes using the Lenstar LS 900 (Haag-Streit, Koeniz, Switzerland).
In this observational and comparative study, 56 normal eyes and 20 cataractous eyes in children between 5 and 15 years of age were included. Measurements were taken before and after cycloplegia using 2% homatropine drops. Parameters studied were axial length, central corneal thickness, keratometry, anterior chamber depth, and lens thickness. The Wilcoxon test was used to compare the effects of cycloplegia on all parameters.
Cycloplegia resulted in a statistically significant decrease in axial length (P < .05), central corneal thickness (P < .05), and lens thickness (P < .001) and an increase in the anterior chamber depth (P < .001) in normal eyes. In the cataract group, cycloplegia resulted in an increase in anterior chamber depth (P < .001) and decrease in lens thickness (P < .001).
Biometry measurements have to be carefully interpreted in pediatric eyes where cycloplegia is an important part of the examination. [J Pediatr Ophthalmol Strabismus. 2018;55(4):260-265.].
使用Lenstar LS 900（瑞士科尼茨哈格-施特雷公司）研究睫状肌麻痹对儿童眼睛光学生物测量参数的影响。
在这项观察性比较研究中，纳入了56只5至15岁儿童的正常眼睛和20只白内障眼睛。使用2%后马托品滴眼液在睫状肌麻痹前后进行测量。研究的参数包括眼轴长度、中央角膜厚度、角膜曲率、前房深度和晶状体厚度。采用Wilcoxon检验比较睫状肌麻痹对所有参数的影响。
在正常眼睛中，睫状肌麻痹导致眼轴长度（P < .05）、中央角膜厚度（P < .05）和晶状体厚度（P < .001）有统计学意义的降低，以及前房深度增加（P < .001）。在白内障组中，睫状肌麻痹导致前房深度增加（P < .001）和晶状体厚度降低（P < .001）。
在睫状肌麻痹是检查重要组成部分的儿童眼睛中，生物测量结果必须谨慎解读。[《小儿眼科与斜视杂志》。2018；55(4)：260 - 265。]
