Effects of glare on contrast sensitivity assessment in patients with age-related cataract

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.
