近视患者暗适应下瞳孔的临床观察与分析

Clinical observation and analysis of sco-topic pupil diameter in myopia patients

目的:观察近视患者暗适应下瞳孔的大小,分析比较不同性别不同屈光度的近视患者暗适应下瞳孔大小的异同。方法:选择来我院接受准分子激光角膜屈光手术的近视患者337例(674眼),使用NIDEK全自动电脑验光仪(mod-el AR-710A)测量其暗适应下瞳孔的直径,分别按性别和屈光度分组,分析对比是否有统计学差异。结果:女性患者暗适应下瞳孔均值为6.2025mm,男性患者暗适应下瞳孔均值为6.0933mm,二者比较无统计学差异;三组不同屈光度患者暗适应下瞳孔大小经方差分析无显著差异。结论:不同性别不同屈光度的近视患者暗适应下瞳孔统计学分析未发现显著差异,近视患者暗适应下瞳孔的大小的测定已成为屈光手术术前评估和手术设计的一个重要步骤。

AIM ： To measure the scotopic pupil diameter in myopia patients and to analyze the correlation between pupile diameter and sex or myopic diopter. METHODS： Totally 337 myopia patients （674 eyes） were measured for pupile diameter under scotopic condition using NIDEK auto refractometer （model AR-710A）. They were divided into 2 groups according to sex, and another 3 groups according to the degree of myopic. RESULTS： The average of pupile diameter under scotopic condition was 6. 2025mm in females and 6. 0933mm in males, with no statistical significance （P 〉 0. 1 ）. And there was no significant difference among three groups of different myopic diopter. CONCLUSION： There is no significant difference between different sex or different degree of myopia. To measure the scotopic pupil diameter in myopic patients has already become an important step of preoperative evaluating and operative design.
