儿童白内障人工晶体植入术后双眼视功能恢复情况的研究

Investigation of the recovery of the binocular visual function after the operation for children cataract

目的 :评价儿童白内障人工晶体植入术后双眼视功能的恢复情况方法 :对 6 0例 14岁以下儿童白内障人工晶体植入术后视功能恢复情况进行回顾性研究。将病人分为单眼先天性白内障、单眼外伤性白内障和双眼先天性白内障三组 ,随访时间为术后半年至 3年半 ,对每位患者进行了最好矫正视力、眼位及双眼视功能检查。结果 :6 0例病人最好矫正视力达到 0 .5以上的有 33例 (5 5 % ) ,具有融合功能的有 2 8例 (4 7% ) ,达到≤ 2 0 0秒弧度立体视觉的只有 15例 (2 5 % ) ,在三组病人中 ,单眼外伤性白内障的术后视力及双眼视功能恢复情况明显好于单眼先天性白内障。结论 :儿童白内障人工晶体植入术后可以获得较满意的视力效果 ,但双眼视功能的恢复情况往往不理想。对儿童先天性白内障在视觉尚未发育成熟之前尽早进行手术、儿童外伤性白内障在伤后早期进行人工晶体植入 ,将有利于儿童白内障术后双眼视功能的恢复。

Objective: To study the recovery of binocular vision after the IOL implantation for children cataract. Methods: 60 cataract patients who were no more than 14 years old were divided into 3 groups, monocular congenital cataract, monocular traumatic cataract and binocular congenital cataract. The best corrected vision position of eye and the binocular visual function were followed up for 0.5-3.5 years. Results: The best corrected vision up to 0.5 was in 33 patients (55%). The patients with fusion power were 28 cases (47%). Only 15 patients (25%) had ≤20 sec/arc stereopsis. The vision and the recovery of the binocular visual function in monocular traumatic cataract were much better than that in the monocular congenital. Conclusions: If IOL implantation is run before vision maturity for children congenital cataracts and in early stage for children traumatic cataract, it will be good to the recovery of the binocular visual function in children cataract.
