目的:观察先天性特发性眼球震颤儿童Parks中间带移位术前后的立体视觉。方法:利用同视机图片和立体图本,检查12例先天性眼球震颤儿童术前和术后6mo正前方远、近距离立体视觉。结果:所有患者术后正前方眼球基本不震颤或明显减轻,12例患儿中7例代偿头位消失,获得立体视觉,5例术后代偿头位改善,其中3例建立同时视觉,但未建立立体视觉。结论:Parks法中间带移位术治疗先天性特发性眼球震颤,不仅能消除和减轻代偿头位与眼球震颤,提高视力,代偿头位消失的患者还能建立远、近立体视觉,提高视觉质量。
Objective: To observe the stereovision of Parks median shift before and after congenital idiopathic nystagmus. Methods: The images of stereopsis and stereogram were used to examine the distance and distance stereo vision of 12 congenital nystagmus patients before and 6 months after operation. Results: In all patients, the eyeball basically did not tremble or significantly alleviate. In the 12 cases, 7 cases of compensatory head disappeared and gained stereopsis, and 5 cases of compensatory head position improvement. Among them, 3 cases established simultaneous vision, But did not establish stereoscopic vision. Conclusion: Parks median shift with the treatment of idiopathic idiopathic nystagmus, not only can eliminate and reduce the compensatory head and nystagmus, improve visual acuity, patients with compensatory head disappeared but also to establish far and near stereo vision, Improve visual quality.
