儿童屈光不正性弱视动态立体视功能评估

Valuation of Dynamic Stereopsis Function in Ametropic Amblyopia

目的:初步评估不同年龄组,不同程度弱视的屈光不正性弱视患儿动态立体视觉的识别及丢失程度,为丰富视功能评估方法及功能训练提供理论依据。方法:收集屈光不正性弱视200例,年龄6~9岁116例,按弱视程度分组,轻度36例,中度45例,重度35例。年龄10~14岁84例,轻度32例,中度30例,重度22例。静态立体视功能检查采用Titmus图,识别60ʺ为通过;采动态立体视功能用知觉感知视功能检查计算机系统检测。SAS软件统计卡方分析。结果:6~9岁组静态立体视通过62例,其中轻度30例,中度22例,重度10例。动态立体视通过86例, 轻度36例,中度32例,重度18例。10~14岁组静态立体视通过65例,其中轻度30例,中度25例,重度10例。动态立体通过78例,轻度30例,中度29例,重度19例。组内静态与动态立体视比较,6~9岁组轻度、中度、重度组及10~14岁重度组动态立体视的通过率均高于静态立体视,存在统计学差异;不同组间比较,10~14岁组中、重度弱视动态立体视的均通过率高于6~9岁组,有统计学差异。结论:动态立体视功能在中、重度弱视儿童和大龄组弱视儿童的通过率高于静态立体视;动态立体视评估,能够获得到更多的中、重度及大龄弱视患儿的视功能信息,更加全面的评估弱视患儿的立体功能状态。

Objective: To preliminarily evaluate the recognition and loss of dynamic stereopsis in children with amblyopia and amblyopia with different degrees of amblyopia in different age groups, so as to provide a theoretical basis for enriching visual function assessment methods and functional training. Methods: 200 cases of ametropic amblyopia were collected, 116 cases aged 6 to 9 years old, grouped according to the degree of amblyopia, 36 cases were mild, 45 cases were moderate, and 35 cases were severe. Aged 10 to 14 years, there were 84 cases: mild 32 cases, moderate 30 cases, severe 22 cases. The Titmus diagram was used for the static stereo vision function inspection, and 60ʺ was recognized as a pass;the dynamic stereo vision function was tested by the computer system of the perceptual perception visual function inspection. SAS software statistical chi-square analysis. Results: 62 cases in the 6~9-year-old group passed static stereopsis, including 30 cases of mild, 22 cases of moderate, and 10 cases o severe. Dynamic stereopsis passed in 86 cases, mild in 36 cases, moderate in 32 cases, and severe in 18 cases. In the 10~14-year-old group, 65 cases passed static stereopsis, including 30 cases of mild, 25 cases of moderate, and 10 cases of severe. Dynamic three-dimensional passed 78 cases, mild 30 cases, moderate 29 cases, and severe 19 cases. In the comparison of static and dynamic stereopsis within the group, the pass rates of dynamic stereopsis in the mild, moderate, and severe groups of 6~9 years old and the severe group of 10~14 years old were higher than those of static stereopsis, and there were statistical differences. In comparison, the pass rate of moderate and severe amblyopia dynamic stereopsis in the 10~14-year-old group was higher than that in the 6~9-year-old group, with a statistical difference. Conclusion: The passing rate of dynamic stereopsis in children with moderate and severe amblyopia and older children with amblyopia is higher than that of static stereopsis;dynamic stereopsis assessment can obtain more visual function information in children with moderate, severe, and older amblyopia, and a more comprehensive assessment of the stereoscopic functional status of children with amblyopia.
