儿童眼外伤76例双眼视功能的观察

目的:测定76例经治疗后的眼外伤儿童立体视训练前后双眼视功能,评价双眼视功能训练对眼外伤儿童立体视的影响。方法:收集2006-01/2009-12期间在我院诊治的儿童眼外伤76例76眼,进行一期修复后,即进行双眼视功能训练。使用AIT-1000同视机检查眼外伤儿童训练前后融合和远立体视功能,使用Titmus立体图检查近立体视功能。结果:训练前无双眼视功能者26眼(34%),训练后无双眼视功能者16眼(21%);训练前有融合功能者27眼(35%),训练后有融合功能者48眼(63%);训练前有远立体视功能者23眼(30%),训练后有远立体视功能者29眼(38%),训练前有近立体视功能者14眼(18%),训练后有33眼(43%)。经统计分析,双眼视功能在训练前后的差异具有统计学意义。结论:对眼外伤儿童及时行双眼视功能训练,有助于重建患儿的双眼视功能。

Analysis of the reconstruction of binocular visual function in 76 cases of pediatric ocular trauma

AIM: To evaluate the effect of binocular visual function training in pediatric ocular trauma. METHODS: There were 76 patients (76 eyes) that were hospitalized with a primary diagnosis of ocular injury at the Affiliated Hospital of Medical College, Qingdao University between January 2006 and December 2009. Binocular visual function training was given after primary wound repair. Far stereopsis function were checked using AIT-1000 synoptophore fusion, and near stereopsis function was checked using Titmus stereogram.Binocular visual function was compared before and after training. RESULTS: Before binocular visual function training,26 eyes（34%）had no binocular vision, after training there were only 16 eyes（21%） without binocular vision. Before undertaking binocular visual function training with fusion, only 27 eyes (36%) had binocular vision, after the training there were 48 eyes (63%) with binocular vision. Before undertaking binocular visual function training with far stereopsis ,there were 23 eyes (30%) with binocular vision, after the training there were 29 eyes (38%). Before binocular visual function training with near stereopsis, there were 14 eyes (18%) with binocular vision, after the training there were 33 eyes (43%) with binocular vision. There was a significant difference in the number of patients with binocular vision before and after binocular visual function training. CONCLUSION:The training is useful for the reconstruction of binocular visual function in pediatric ocular trauma.
