光镜观察显示红螯螯虾复眼的每个小眼从远端到近端分别由角膜、4个角膜生成细胞、4个晶锥细胞组成的晶锥及小网膜细胞构成。

Purpose: To investigate the influence of retinal photocoagulation with an indirect ophthalmoscopy contact lens on corneal endothelial cells.Methods: Seventeen eyes of 17 patients were evaluated, and corneal endothelial cells were measured twice: just before retinal photocoagulation using an indirect ophthalmoscopy contact lens and 33.2 ± 10.2 days after surgery.

为研究采用间接检眼镜接触镜进行视网膜激光光凝对角膜内皮细胞的影响，对17例患者的17眼进行检测并对角膜内皮细胞检测两次：视网膜激光光凝术前和术后33.2±10.2天检测。

Corneal biopsy with 178.2mmol.L-1 potassium hydroxide slide is a rapid and simple method with high positive rate in diagnosis of fungal corneal ulcer.

CASE REPORTSThe examination including slitlamp examination, tear breakup time, schirmer I test and fluorescent staining were performed in 97 outpatients with symptoms of asthenopia, foreign body sensation and dryness. The positive cases in BUT, SIt, fl staining and obstruction of tarsal glands and were 51,38,31 and 34 cases, respectively.

病例报告］对97例具有视疲劳、异物感及眼干涩等症状的门诊患者进行裂隙灯检查、泪膜破裂时间实验、泪液分泌实验及角膜荧光染色等检查，所有患者中泪膜破裂时间实验、泪液分泌实验、角膜荧光染色及睑板腺异常的阳性例数分别为51，38，31，34例。

Methods The tangential curvature of the anterior cornea was measured every 0.3 mm from the apex in 360 meridians by an Orbscan-Ⅱ topographer.

Methods: The corneal thickness was measured before and 1,3,6,12 and 24 months after PRK with an DGHA biometer; the grades of Haze after PRK were examined with a slit-lamp biomicroscope.

采用美国DGHA型生物测量仪测量PRK术前及术后1、3、6、12与24月的角膜中心厚度，显微裂隙灯下观察PRK术后角膜雾状混浊的情况。

Results: The main reasons for a change to the piggyback lens were excessive scar ring (40%) and the decentration of HCL (35%).

结果：圆锥角膜变更使用Piggyback Lens 的主要原因是角膜混浊、瘢痕的加重（40%）和单独使用HCL稳定性差，易脱落（35%）。

It is showed that the lamellar kerato plasty is a reasonable therapeutic method for pterygium and corneal dermoid tumor.

结果表明板层角膜移植可使角膜完整、植片透明、减少散光、提高视力并降低术后翼状胬肉的复发率，是一种理想的治疗方法，值得推广。

There was no difference in the sensitivity or specificity of the Ectasia Risk Score System in the population from which it was derived and this independent population of ectasia cases and controls.

在此由角膜扩张病例和对照病例构成的独立人群中，角膜扩张风险评分系统的敏感性和特异性没有差别。

PURPOSE: To validate the Ectasia Risk Score System for identifying patients at high risk for developing ectasia after laser in situ keratomileusis.

目的：验证用来鉴别LASIK术后具有较高风险发生角膜扩张的患者的角膜扩张风险评分系统。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。
