视力

Methods Sixty students(120 eyes)with myopia(within-2.50D)were selected.visival acuity,cycloplegic refraction,keratometer,ocular axis,stereoscopic vision,and phoria strabismus were observed before and after 1～1.5 years wearing Anti-myopia Glasses.

方法60例(120眼)近视度在-2.50D以内的中小学生，观察其戴镜1～1.5年后的裸眼远视力、屈光检查结果、角膜曲率、眼轴长度、立体视觉及隐斜度的变化。

METHODS: From January 2001 to October 2002, 21 high myopia patients (39 eyes) with borderline corneal thickness were treated with LASIK. Visual acuity, keratometry readings and central corneal thickness were measured at 3 years after surgery. These data were compared with preoperative and early postoperative results.

选2001-01/2002-10在我院行LASIK手术的高度近视相对薄角膜患者21例39眼，查术后3a的视力、眼压、屈光状态、角膜曲率及中央角膜厚度，并与术前及术后早期数据进行统计学比较分析。

Keratometry measurements were obtained preoperatively, at postoperative 1 week, 1 month and 6 months respectively. SIAs were analyzed by "Cravy vector method". The mean SIA and uncorrected visual acuity were compared among the groups up to 6 months postoperatively.

测量术前、术后1周、1、3和6个月的角膜曲率，运用Cravy向量分析法计算SIA度数及方向，比较3组术后不同时间的平均SIA度数及裸眼视力。

There were some specific examinations according to conditions of different patients, including multipoint corneal thickness, time-related keratometry, glare, contrast sensitivity, function of muscular apparatus, VEP, and so on.

除视力、屈光度、主视眼、角膜厚度、角膜地形图、像差检查等常规术前检查外，还要依据患者情况进行相应的特殊检查，包括角膜多点厚度、角膜曲率时间变化、眩光仪、对比敏感度、眼肌功能、VEP五项等检查。

Natural changes result in lenticular sclerosis, whichtypically does not cause significant vision loss.

晶状体的物质改变导致其硬化，此典型上是不会造成显着地视力减退。

Dizziness, lightheadedness, headache, blurred vision, loss of appetite, stomach upset, diarrhea, or constipation may occur as your body adjusts to the medication. You may also experience decreased sexual ability or increased sensitivity to the sun.

药物适应期间可出现头昏、头晕、头痛、视力模糊、食欲不振、胃不适、腹泻或便秘等现象，也可能出现性能力下降或对日光敏感度增加等情况。

Pituitary apoplexy is characterized by headache, visual loss, meningism, ophthalmoplegia, vomiting, hormonal dysfunction, and altered mental status caused by sudden hemorrhage or infarction of the gland.

垂体卒中是由于垂体腺瘤的突然出现或梗死从而引起头痛、视力丧失、假性脑膜炎、眼肌麻痹、呕吐、激素性功能障碍以及精神状态异常。

The patient with sphenoidal meningocele complicated by cerebrospinal fluid leakage, visual decrease and endocrine disorder can be treated by surge

对合并脑脊液鼻漏及明显视力下降、内分泌障碍的蝶窦脑膜脑膨出病人，可考虑手术治疗；内镜经鼻手术是首选外科治疗方法。

METHODS: In 44 eyes of 22 subjects (mean age +/- standard deviation , 24.0 +/- 3.2 years) with orthokeratology, ocular aberrations and mesopic contrast sensitivity were determined before and three months after commencement of the procedure.

对22名受试者（平均年龄±标准差，24.0±3.2岁）的44只眼在接受角膜塑型术治疗前和治疗后3个月时测量眼像差和中间视力对比敏感度。

Furthermore, significant correlation was found between the amount of myopic correction and the induced changes in log mesopic contrast sensitivity (r =-0.442, P =.0038 without glare; r =-0.464, P =.0024 with glare).

此外，近视矫正量与中间视力对比敏感度log值的变化之间呈显著相关(r =-0.442， P =。0038 无眩光； r =-0.464， P =。0024 有眩光)。
