儿童眼外伤治疗前后双眼视觉功能观察

目的 观察儿童眼外伤76例治疗后的双眼视功能,并对其相关因素进行分析.方法 3～14岁儿童眼外伤76例（76眼）,于眼外伤一期修复后检查视力,分≤0.3,0.4～0.6和≥0.6 3组.使用AIT-1000型同视机及Titmus检查治疗后患儿的融合和立体视功能,对具有融合或立体视功能的患儿按年龄分成3～5岁、6～7岁和8～14岁3组.统计治疗前后不同视力差异,以及不同年龄和不同视力间双眼视功能的差异.结果 76例治疗后视力较治疗前有明显提高（P＜0.01）.视力≤0.3者,无1例具有融合或立体视功能.视力在0.4以上具有融合功能者39例,具有远立体视者25例,具有近立体视者33例.39例具有融合功能的患儿,0.4～0.6和≥0.6两组间不管是融合还是远、近立体视,≥0.6者例数均较多,差异有统计学意义（P＜0.05）.6～7岁与3～5岁和8～14岁间不管融合、远立体视还是近立体视比较,6～7岁组例数均较少,差异有统计学差异（P＜0.05）.而3～5岁与8～14岁患儿间的融合、远、近立体视差别均无统计学意义（P＞0.05）.结论 儿童眼外伤双眼视功能的恢复与视力恢复成正相关.6～7岁间患儿双眼视功能恢复情况较3～5岁与8～14岁患儿的差.

The binocular vision of pediatric ocular trauma

Objective To observe the binocular vision in 76 pediatric ocular trauma, and analysis its relative factor. Methods There were 76 children(76 eyes) of 3 to 14 years old with ocular trauma. We examined their vision after primary wound repair. According the vision, we divided them into three groups: ≤0. 3,0.4-0.6 and ≥0.6. We divided the children of different ages into three groups according to the fusion or stereopsis using AIT-1000 synoptophore and Titmus stereogram:3 ～ 5 years old、6 ～ 7 years old、8 ～ 14years old. The vision was compared before and after treatment, the difference of binocular vision between different vision and different age were analysed. Results The binocular vision of difference visual:no patients had binocular vision if the vision less than 0. 3. 50 patients had a vision of more than 0. 4, only 39 patients have the function of fusion, 25 patients have far stereopsis,33 patients have near stereopsis. In the 39 patients with visual function of fusion, the difference between visual acuity of 0.4 ～0.6 and of ≥0.6 had statistical significance (P ＜0.05 ) ,the later one had more cases with visual function of fusion,far stereopsis and near stereopsis. The fusion 、far or near stereopsis of 6 ～7 years old group were less than the 3 ～5 years group and the 8 ～ 14 years group ( P ＜ 0.05 ). The fusion 、far or near stereopsis of 3 ～ 5 years group had no difference compared with 8 ～ 14 years group ( P ＞ 0.05). Conclusion The recovery of binocular vision is positive related to the recovery of vision. The recoveries of binocular vision of children aged 6 to 7 years were poor compared with the children aged 3 to 5 and children aged 8 to 14 years old.
