摘要
目的:观察眩光对年龄相关性白内障患者对比敏感度的影响。方法:选取年龄相关性白内障患者22例(30眼),年龄46～84岁,矫正视力0.5～0.8,应用Optec6500视功能测试仪测试不同空间频率(1.5、3.0、6.0、12.0和18.0c/d)的眩光和无眩光条件下(分明亮条件和昏暗条件)白内障患者的对比敏感度。结果:眩光在1.5、3.0和6.0c/d的空间频率下影响患者的对比敏感度(明亮条件下:t=3.359、3.172和5.072,P<0.05;昏暗条件下:t=9.852、9.354和2.493,P<0.05)。结论:眩光主要影响中低空间频率下白内障患者的对比敏感度。
Aim：To analyze the effect of glare on contrast sensitivity assessment in patients with age-related cataract.Methods：Twenty-two patients（30 eyes） with age-related cataract were collected.The patients aged from 46 to 84 years with the best corrected visual acuity from 0.5 to 0.8.Contrast sensitivity with and without glare at different spatial frequency（1.5,3.0,6.0,12.0,and 18.0 c/d） were measured.Results：Photopic and mesopic glare decreased contrast sensitivity at low and medium spatial frequency（1.5,3.0,6.0 c/d）（photopic condition：t=3.359,3.172,and 5.072,P0.05;mesopic condition：t=9.852,9.354,and 2.493,P0.05）.Conclusion：Glare mainly influences contrast sensitivity in the patients with age-related cataract at low and medium spatial frequency.
