目的 分析功能性视力不良患者集合功能、调节功能特点,研究双眼视觉训练对功能性视力不良患者的疗效.方法 回顾性研究.收集2012年7月至2013年10月于天津市眼科医院视光中心视觉训练工作室就诊的功能性视力不良的患者20例,平均年龄(11.2±5.9)岁.所有患者均排除眼部疾病、弱视危险因素和全身性疾病.在屈光矫正的基础上进行双眼视功能检查.分析、诊断后进行视觉训练治疗以提高矫正视力.采用配对t检验、Spearman相关性分析等进行统计分析.结果 患者右眼屈光度为+2.25～-8.75 D,左眼屈光度+2.87～-8.63 D.根据双眼视功能检查结果发现20例患者中,有13例诊断为集合不足并伴调节功能异常,有4例诊断为调节过度,2例为基本型外隐斜,1例为散开不足.经过2个月的视觉训练治疗,所有患者远、近矫正视力均提高到1.0(Z=-3.948,P＜0.01;Z=-3.193,P＜0.01).视力恢复后集合功能指标近距离融像范围(PRV)破裂点增加(t=-5.173,P＜0.01);单眼调节灵敏度(MAF,Z=3.928,P＜0.01)、双眼调节灵敏度(BAF,Z=-3.835,P＜0.01)、正负相对调节(PRA,t=4.094,P＜0.01;NRA,t=-4.254,P＜0.01)等调节功能均恢复到正常,差异有统计学意义.进行相关分析发现,训练前矫正远视力(r=-0.584,P＜0.01;r=-0.658,P＜O.01)、训练前矫正近视力(r=-0.451,P＜0.01;r=-0.540,P＜0.01)均与远隐斜、近距离融像范围呈负相关.结论 功能性视力不良患者通常伴有集合功能、调节功能不良,进行有效的视觉训练治疗,可以提高视力.

Objective To evaluate the efficacy of vision training on functional vision loss and to analyze binocular vision characteristics in patients.Methods This retrospective study was performed at the ophthalmic center,Tianjin Eye Hospital from July 2012 to October 2013.Twenty patients with functional vision loss were enrolled,including 10 males and 10 females.The average age was 11.2±5.9 years.All patients had routine examinations that excluded eye disease,amblyopia risk factors,and systemic disease.Based on the binocular vision characteristics,all patients participated in personalized vision training.All data were statistically analyzed with a paired samples t test and Pearson correlations.Results Right eye refraction of patients ranged from +2.25 to-8.75 D; left eye refraction ranged from +2.87 to-8.63 D.Thirteen patients had convergence insufficiency,4 had accommodative excess,2 had basic exophoria and 1 had divergence insufficiency.After 2 months of vision training,distance and near vision in all patients had improved to 1.0 (Z=-3.948,P＜0.01; Z=-3.193,P＜0.01).Near positive relative vergence (PRV) break point improved as well (t=-5.173,P＜0.01).Additionally,monocular accommodative facility (MAF,Z=3.928,P＜0.01),binocular accommodative facility (BAF,Z=-3.835,P＜0.01),positive relative accommodation (PRA,t=4.094,P＜0.01),and negative relative accommodation (NRA,t=-4.254,P＜0.01) had significantly improved.In addition,both distance vision (r=-0.584,P＜0.01; r=-0.658,P＜0.01) and near vision (r=-0.451,P＜0.01; r=-0.540,P＜0.01) were correlated with far exophoria and near positive relative vergence.Conclusion The occurrence of functional vision loss is apparently related to binocular vision dysfunction in these patients.Visual acuity can be improved with vision training.
