摘要
目的观察屈光不正性弱视和正常儿童的立体视觉。方法运用颜少明《随机立体检查图》、随机点同视机立体图、同视机,对57例矫正视力正常(≥0.9)的屈光不正儿童和50例正常儿童进行立体视觉测定,并予统计学处理。结果(1)与正常儿童比,屈光不正性弱视儿童的零视差、交叉视差、非交叉视差和远立体视均明显差,差异有统计学意义(P<0.05);远融合范围无明显差异,差异无统计学意义(P>0.05)。(2)屈光不正性弱视儿童矫正前,轻度组与中度组交叉视差比较差异有统计学意义(P<0.05),其余指标均无明显差异,差异无统计学意义(P>0.05)。结论屈光不正性弱视严重影响儿童立体视觉的形成;积极预防、早期发现、有效矫正治疗屈光不正性弱视十分重要。
Objective To observe the stereoscopic vision in ametropic amblyopia and normal children. Methods The stereoscopic vision in 57 ametropia children with normal corrected vision（ ≥ 0.9）and 50 normal children were measured and statistically evaluated by using＂Random stereoscopic examination diagram＂written by Yan Shaoming,synoptophone of random-dot stereopsis and synoptophore. Results （1） Compared with normal children,the zero disparity,crossed dlsparity,uncrossed disparity and far stereopsis in ametropie amblyopia children were aU significantly worse（P 〈 0.01 or P 〈 0.05）;the distance fusion range had no obvious difference.（2） There were no significant difference of the indexes excluding crossed disparity between mild group and moderate group in ametropic amblyopia children before correction of the vision. Conclusion hmetropic amblyopia affects the formation of children＇s stereoscopic vision badly.Thereby,Ametropic amblyopia should be prevented,detected early and corrected effectively
