脑卒中后眼球运动障碍行为视觉训练的效果

Effect of behavioral vision training on post-stroke ocular motility disorders

目的探讨行为视觉训练对脑卒中后眼球运动障碍的效果。方法2023年8月至10月,北京博爱医院脑卒中后眼球运动障碍住院患者21例,行行为视觉训练,包括脑视觉训练和视觉融合训练,共4周。治疗前后,采用Snellen视力表、斜视三棱镜度和近立体视功能评价视觉功能。结果训练后,患者右眼和左眼视力均明显改善(Z_(右眼)=-3.601,Z_(左眼)=3.012,P<0.01);斜视三棱镜度显著减小(t=8.930,P<0.001);近立体视功能无明显变化(P>0.05)。结论行为视觉训练可以改善脑卒中后眼球运动障碍患者的视力,减轻斜视。

Objective To explore the effect of behavioral vision training on post-stroke ocular motility disorders(PSOMD).Methods From August to Octobor,2023,a total of 21 PSOMD patients in Beijing Bo'ai Hospital were selected.They received behavioral vision training,including brain-based visual training and visual fusion training,for four weeks.Visual function was assessed with Snellen eye chart,strabismus prism and Titmus near stereopia.Results The vision of both right and left eyes improved after training(Z_(right eye)=-3.601,Z_(left eye)=3.012,P<0.01),while the strabismus prism reduced significantly(t=8.930,P<0.001).But Titmus near stereopia showed no difference(P>0.05).Conclusion Behavioral vision training could improve vision and strabismus after stroke.
