Flash visual evoked potential has been used as monitoring method during surgery of sellar tumors in an effort to protect chiasmal injury from surgical manipula- tion, to know whether the optic ways have been decompressed immediately after tumor removed, and to know immediately the positivity of better visual outcome.

选用闪光视觉诱发电位对10例鞍区肿瘤手术的全过程进行监护，旨在防止可能造成视路损伤的手术操作及术中了解视路减压情况。

RESULTS: Eight affected subjects had subnormal visual acuity due to high myopia. The results of colour vision tests were consistent with red-green CVD in six of these affected subjects. Fundus examination showed degenerative myopic changes characterized with generalized chorioretinal atrophy.Abnormal cone and rod dark-adaptation and diminished cone response in ERG were found in two subjects. According to family pedigree, it has been suggested that red-green CVD has X-linked recessive inheritance.

结果：患者8位均因高度近视视力下降，其中6例有红绿色觉缺失，眼底检查显示以弥漫性视网膜脉络膜萎缩为特征的近视改变。2例患者ERG检查出现视杆细胞的暗适应异常和视锥细胞的反应消失，根据家系，红绿色觉缺失属X连锁的隐性遗传。

The comparison group uses the pure non-pain induced abortion technique,the experimental group uses the visible non-pain induced abortion technique,observes and records two groups of patients' the formation rate,the surgery which after surgery hemorrhage quantities,leaks attracts the colporrhagia time and the illness complication formation rate,thus compares two surgeries methods the surgery quality.

目的：探讨可视无痛人工流产术与单纯无痛人工流产术的手术质量是否不同。方法：纳入符合标准的125例门诊病人，随机分为对照组和试验组。对照组采用单纯无痛人工流产术，试验组采用可视无痛人工流产术，观察并记录两组病人在手术中的出血量、漏吸的发生率、手术后阴道出血时间及并发症的发生率，从而比较两种手术方法的手术质量。

AIM: To evaluate the agreement among different stereotests and the effect of comitant strabismus on stereoscopic vision.

目的：研究不同检查方法检测斜视患者立体视锐度的一致性，以及不同类型斜视立体视损害的差异。
