论双眼视力与单眼视力的不统一性

Argumentation about the discordance of binocular vision and monocular vision

目的针对临床中部分患者单眼视力正常，而双眼视力下降的现象，探讨双眼视力与单眼视力的不同含义，并分析其引起双眼视力下降及双眼视功能异常的原因和机制。方法分别检查患者的单眼、双眼裸眼远、近视力及矫正视力，眼位，眼球运动，眼前节和眼底，电脑加综合验光仪验光，同视机、三棱镜、立体视功能检查。结果15例单眼视力正常而双眼视力低下患者中，3例患者为中高度远视，6例患者为间歇性外斜视；另6例患者存在轻度屈光参差。根据其不同原因给予矫正后，双眼视力得到明显提高。结论临床工作中除常规检查单眼视力外，还应重视双眼视力及双眼视功能的检查，并给予相应治疗。

Methods naked Distant vision and near vision of simple eye, those of oculus uterque, and corrected visual acuity, eyeball position ,eye movement are examined. Preocluar and eyeground examining. Optometry using the phoropter. Synoptophore, prism and stereopsis checking. Results 15 patients of monocular vision is normal while binocular vision is weak ,three are medium or high hypermetropia, six are intermittence exotropia, other six are mild anisopia. ARer the therapy on the grounds of different causes, binocular vision is elevated.
