近视

PURPOSE: To investigate mesopic contrast sensitivity and night driving ability in eyes undergoing overnight orthokeratology, and to analyze the relationship among mesopic contrast sensitivity, ocular higher-order aberrations, and myopic correction.

目的：研究夜戴型角膜塑型术后的中间视力对比敏感度和夜间驾驶能力，分析中间视力对比敏感度、眼高阶像差和近视矫正之间的关系。

Mesopic contrast sensitivity after overnight orthokeratology is deteriorated significantly as ocular higher-order aberrations increase, and these changes depend on the amount of myopic correction.

夜戴型角膜塑型术后的中间视力对比敏感度由于高阶像差的增加而显著降低，而这些变化都依赖于近视矫正量。

We discuss a series of 11 patients seen at the Cole Eye Institute with the condition of myelinated retinal nerve fibers, myopia, and amblyopia and describe the clinical characteristics.

我们讨论了 Cole 眼科中心11例视网膜有髓神经纤维，近视和弱视的病人的临床特征。3名病人已经有视神经发育异常，并对相关文献进行了综述。

The active standard of ophthalmological health examination has certain defects, and it is necessary to revise it, to strengthen the power of conscription management.

MethodsThe low,middle,high myopia of LASIK 150 cases (300 eyes) with the non-contact ophthalmotonometer and corneal pachymeter were measured.

以非接触眼压计、角膜测厚仪测量低、中、高度近视LASIK手术150例（300眼）。

Methods The central corneal thickness of 637 patients (1210 eyes) of myopia was measured with DGH-4000 pachymeter before and 1、3 month after LASIK.

应用 DGH- 40 0 0型超声角膜测厚仪分别测量6 37例(12 10只眼)近视患者在施行 L ASIK手术前及术后 1月、3月的角膜中央厚度；根据术前的屈光度分为 4组，对各组所测得角膜中央厚度的数值进行分析。

METHODS:The data of 306 patients (612 eyes) were measured with ultrasonic pachymeter, noncontact tonometry, automatic refractor, A scan ultrasonography and corneal topography, and the patients were analyzed on age, sex, race, occupation, address, family history of myopia, history of corneal contact lenses, left or right eye, naked vision and corrected vision.

近视眼306例612眼用超声角膜测厚仪、电脑验光仪、非接触眼压计、A超和角膜地形图分别测量其数据。并分析其年龄、性别、民族、职业、住址、近视家族史、配戴角膜接触镜史、眼别、裸眼视力、矫正视力。

RESULTS: Localised peripapillary detachments did not cause any symptoms by themselves and all the lesions were recognized because of other ocular problems.

结果：视盘周围视网膜脱离不是任何患者就诊检查的原因，视力减退或矫正视力低的原因是相对严重的近视性视网膜脉络膜萎缩、CNV、黄斑前膜形成和弱视。5只患眼表现为1型后巩膜葡萄肿，其视盘周围视网膜脱离均位于视盘的鼻侧半，而另5只患眼表现为3型或2型葡萄肿，其视盘周围视网膜脱离均位于视盘的非鼻侧半，统计学上存在差异（P=0.01）。

本发明主要目的是提供一种用于治疗近视的水性眼用制剂，其含有与药物可接受的凝胶载体结合的哌仑西平。

Results The values for distance lateral phoria and stereopsis acuity were-1.64°±2.10° and 112.17 "±95.79", respectively.

结果 本组近视患者中，视远时水平隐斜视为－1.64°±2.10°。9例为正位眼，3例隐内斜，38例隐外斜，2例未测出。
