摘　　要：目的观察和探讨感知觉学习对小角度间歇性外斜视患儿的疗效。方法收集32例小角度间歇性外斜视患儿,行感知觉学习训练3个月。训练前后检查斜视度,同视机检测3级视功能,Titmus立体视检查图观察近立体视,采用t检验,χ~2检验数据分析。结果训练前33cm斜视度为-15.84±7.14~Δ,训练3个月后为-12.81±5.31~Δ,差异有统计学意义(t=2.586,P<0.05);训练前6m斜视度为-9.18±8.59~Δ,训练3个月后为-7.56±5.88~Δ,差异无统计学意义(t=1.666,P>0.05)。训练前32例患者均存在二级融合功能,但融合范围小,训练后分开功能变化不大,差异无统计学意义(t=-1.252,P>0.05);辐辏功能较前明显增强,差异有统计学意义(t=-3.954,P<0.05),训练后融合范围扩大。训练前近立体视≤60″的有17例,训练后≤60″的增加至24例,使用同视机检查远立体视,训练前远立体视存在的有18例,训练后增至27例。结论感知觉学习可以改善小角度间歇性外斜视患者的双眼视功能,提高其日常眼位控制能力。Objective To observe and discuss the efficacy of perceptual learning for patients with small-angle intermittent exotropia.Methods 32 patients with small-angle intermittent exotropia were taken perceptual learning for 3 months.All patients were checked the strabismus angle,detected the three-level visual fuction with synoptophore, and near stereopsis with Titmus stereogram before training and 3 months after training.All datas were statistically analyzed by a t test or x-2 test.Results The mean 33 cm angle of strabismus was-15.84±7.14-Δ before training, and after training was-12.81 ±5.31-Δ, the difference was statistically significant（t =2.586, P〈0.05）.The mean 6m angle of strabismus was-9.18±8.59-Δbefore training, and after training was-7.56 ±5.88-Δ, there was no statistical difference（t =1.666,P〈0.05）.All patients had fusion function before training,but the fusion range was small.After training the divergence had little change,the difference was not statistically significant（t =-1.252,P〈0.05）.But the convergence was increased markedly, the difference was statistically significant（t =-3.954, P〈0.05）,the fusion range was enlarged.There were 17 cases with near stereopsis（≤60″） before training and 24 cases after training.There were 18 cases with far stereopsis before training and 27 cases after training.Conclusions Perceptual learning can improve the binocular visual fuction for patients with small-angle intermittent exotropia,and promote the control of daily eye position.
