Abstract
Purpose: To determine the frequency of cataract in diabetic verses non-diabetic
patients.
Study Design: Descriptive cross-sectional study.
Place and Duration of Study: Eye Outpatients Department of Fatima Memorial
Hospital Lahore from December to March 2018.
Material and Methods: Patients between 20-50 years of age with and without
diabetes were included in the study. The diabetic patients included in the study
had diabetes for at least 6-7 years. Patients with any other systemic disease and
patients <20 years and > 50 years were excluded from the study. All patients
underwent a complete eye examination including uncorrected and best corrected
visual acuity, refraction, dilated slit lamp and fundus examination.
Results: A total of 194 patients were examined. Average duration of diabetes
was 6-7 years with age groups 20-35 years (34.02%) and 35-50 years (65.97%).
There were 79 (79.79%) patients with diabetes who had cataract while only 13
(13.68%) non- diabetic patients had cataract. Most common type of cataract in
diabetic patients was posterior subcapsular cataract (PSCC) 43 (54.43%). This
was followed by nuclear cataract in 17 (21.51%) and cortical cataract in 14
(17.72%) patients. While in non-diabetic patients nuclear cataract was seen in 6
(46.15%) patients and cortical and PSCC were the same percentage 3 (23.07%).
Cataract frequently developed in the age group of 35-50 years in diabetic
patients.
Conclusion: Diabetic patients should be screened for cataract early as PSCC
can cause significant deterioration of vision between 35-50 years.
