چکیده    Objective: to determine the frequency and types of age-related cataract in type 2 diabetic patients compared to non-diabetics. methods: this comparative,cross-sectional study was carried out at al-ibrahim eye hospital,karachi,from july 2014 to june 2015,and comprised both diabetics and non-diabetics. all patients were selected from the out-patient department and had their full ocular examination done,including retinal screening of diabetic patients with non-mydriatic fundus camera. the criterion for diagnosis of cataract was sufficiently advanced lens opacity that caused impaired vision/un-gradable images. cataract was classified on a morphological basis into cortical,nuclear,posterior sub-capsular and mixed types. results: of the 49,384 patients,4,556(9.2%) were diabetics and 44,828(90.8%) were non-diabetics. among the diabetics,cataract was found in 1,956(42.9%) compared to 7,050(15.7%) in non-diabetics. adjusted odds ratio (95% confidence interval) between the two groups was 4.40 (range: 4.11-4.71) (p<0.001). male-to-female adjusted odds ratio (95% confidence interval) was 2.05 (range: 1.95-2.15) (p<0.001). nuclear sclerosis was the commonest type in 2,123(46.6%) cataract cases in diabetics whereas posterior sub-capsular cataract was the commonest type in 14,480(32.3%) cases among the non-diabetics. conclusion: cataract was four times more common in diabetics and twice more frequent in men. nuclear sclerosis was the commonest type of cataract in diabetic patients. © 2016,pakistan medical association. all rights reserved.
