摘　　要：目的初步评价并分析增视能训练软件对屈光不正性及屈光参差性弱视治愈后患儿的立体视觉训练的疗效。方法应用国家医疗保健器具工程技术研究中心研制的虚拟网络训练软件（增视能）对47例立体视功能异常的弱视治愈患儿进行立体视训练，年龄5—8岁，其中屈光不正性弱视29例，屈光参差性弱视18例，矫正视力≥0．8，训练时间3个月。采用颜少明《随机立体检查图》、Lang型和L型立体检查图以及同视机检测其训练前后近立体视、交叉视差及非交叉视差和远立体视锐度。结果屈光不正组训练前近立体视60″3例，占10．34％；远立体视锐度60″2例，占6．89％；交叉视差达100″4例占13．79％；非交叉视差达100″2例占6．89％。训练后近立体视达60″15例，占51．72％；远立体视锐度达60″11例，占30．03％；交叉视差达100″17例，占58．62％；非交叉视差达100″9例，占24．14％。屈光参差组训练前近立体视60″1例，占5．26％；交叉视差达100″1例占5．26％；非交叉视差及远立体视锐度均无正常者。训练后近立体视达60″9例，占47．37％；远立体视锐度达60″7例，占36．84％；交叉视差达100″10例，占52．63％；非交叉视差达100″6例，占31．58％。治疗前后两组立体视功能均有不同程度改善，统计学差异显著P〈0．05。结论增视能软件能有效改善屈光性弱视治愈患儿的远、近立体视觉；对屈光不正性弱视治愈儿的效果优于屈光参差性弱视治愈儿。Objective To evaluate the clinical efficacy of the software for visual virtual reality on treatment of abnormal stereoacuity. Methods Forty-seven children with abnormal stereoacuity came from cured anisometropia or ametropic amblyopia were treated with the software. Among them, 18 cases were anisometropia amblyopia;29 cases were ametropic amblyopia. All of visual acuity were -〉 0.8. Far stereopsis acuity, near stereopsis acuity, crossed disparity and uncrossed disparity were examined with synoptophore, Yan tests,Lang and L tests in each group. Results Ametropic amblyopia group：near stereopsis acuity and far stereopsis acuity with -〈 60″ were 3 （10.34%） and 2 （6.89%）, crossed disparity and uncrossed disparity with -〈 100″ were 4 （ 13.79% ） and 2 （6.89%）. Anisometropia amblyopia group：near stereopsis acuity and far stereopsis acuity with 〈 60″ were 1 （5.26%） and 0,crossed disparity and uncrossed disparity with -〈 100″ were 1 （5.26%） and before treatment. After 3 months of the treatment,Ametropic amblyopia group：near stereopsis acuity and far stereopsis acuity with -〈 60″ were 15 （51.72% ） and 11 （30.03%）, crossed disparity and uncrossed disparity with -〈 100″ were 17（58.62%） and 11 （30.03%）. Anisometropia amblyopia group ：near stereopsis acuity and far stereopsis acuity with -〈 60″ were 9 （47.3%） and 7 （36.84%）, crossed disparity and uncrossed disparity with 〈 100″ were 10（52.63%） and 6（31.58%）. Conclusions The software for visual virtual reality is a new ef- fectual remedy for stereopsis acuity with cured amblyopia, especially for ametropic amblyopia children.
