【摘要】：目的研究近视眼对比敏感度(CS)的不同影响因素。方法随机选取行近视准分子激光的患者62例124眼,矫正视力均≥1.0。分别根据屈光度、年龄和瞳孔大小分组。采用CGT-1000对比敏感度仪分别进行眩光及非眩光状态下的对比敏感度测试。结果在眩光时的对比敏感度均低于无眩光时。眩光状态下,按年龄分组,40岁组和40～60岁组间对比敏感度的差异无统计学意义(P0.05),≥60岁组的对比敏感度在各个空间频率点上均明显低于40岁组和40～60岁组(均P0.05)。正视组、中低度近视组与高度近视组间的差异均有统计学意义(均P0.05),但正视组与中低度近视组的差异无统计学意义(P0.05)。瞳孔6 mm及≤6 mm两组间的差异无统计学意义(P0.05)。非眩光状态下按以上方法分组比较,结果与眩光时一致。结论年龄、屈光度明显影响近视眼对比敏感度,而瞳孔大小影响不明显。
[Abstract]:Objective to study the different influencing factors of contrast sensitivity (CS) in myopia. Methods Sixty-two patients (124 eyes) with myopic excimer laser were randomly selected. The corrected visual acuity was better than 1.0. They were grouped according to diopter, age and pupil size. The contrast sensitivity of glare and non-glare were tested by CGT-1000 contrast sensitivity instrument. Results the contrast sensitivity of glare was lower than that of no glare. Under glare condition, there was no significant difference in contrast sensitivity between 40 years old group and 40 ~ 60 year old group according to age group. The contrast sensitivity of 鈮，
