不同注视性质弱视治愈前后立体视的变化

CHANGES OF STEREOPSIS IN PATIENTS WITH AMBLYOPIA OF DIFFERENT FIXATION PATTERN BEFORE AND AFTER THE CURE OF VISUAL ACUITY

目的探讨不同注视性质的弱视治愈前后立体视变化以及注视性质与立体视恢复关系。方法采用颜少明《立体视觉检查图》和同视机随机点立体视图片（定性画片）,检测281例不同注视性质弱视病儿治愈前后近立体视和远立体视。结果弱视治愈后近、远立体视均有明显的改善（χ2=6.116~40.772,P〈0.01）,弱视治愈前、后正常远立体视检出率均较近立体视大（χ2=9.599、20.894,P〈0.05）,不同注视性质弱视近、远立体视恢复结果差异无显著性（χ2=0.350、0.096,P〉0.05）。结论不同注视性质的弱视在治疗过程中均需积极进行双眼视功能锻炼,其立体视觉预后没有明显不同。

Objective To observe the changes of stereopsis in patients with amblyopia of different fixation pattern（ADFP） before and after the cure and the association between fixation pattern and the recovery of stereopsis.Methods YAN＇s near stereoscopic chart and random dot synoptophore stereogram were used to examine the near and far stereoacuity,respectively,in 281 children with ADFP before and after the cure of the disease.Results After the cure,both near and far stereoacuity were significantly improved（χ2=6.116-40.772,P0.01）;both before and after the cure,the detection rate of far stereoacuity was higher than that of the near stereoacuity（χ2=9.599,20.894;P0.05）.The difference of recovery of near and far stereoacuity among different ADFP was not significant（χ2=0.350,0.096;P0.05）.Conclusion During the course of therapy for patients with ADFP,functional exercise for both eyes should be carried out,the prognosis of stereoacuity was not obviously different among different fixation pattern.
