Association between Type of Cataract According to LOCS Classification with Diabetes Mellitus

Abstract

Prevalence of diabetes mellitus has increased over time. DM has several adverse effects on body, out of which cataract is the most common ocular complication. Cataract is found to be more common in patients with diabetes mellitus due to changes in the metabolism of body. Objectives: To determine the association of type of cataract according to LOCS classification with diabetes mellitus. Methods: The age of the patients was in the range of 25-80 years old. The inclusion criteria were the diabetic patients having the diabetic history of more than 8 years. Patients who were older than 80 years old and who had a history of any systemic disease were disqualified from the trial. All of the patients who were included underwent thorough eye examination. Results: 98 patients were included in the study having positive history of diabetes mellitus. The most common kind of cataract in people with diabetes is PSCC. There were 51 participants with posterior sub-capsular cataract (PSCC) (52.0 percent). This was followed by nuclear sclerosis cataract in twenty (20.04%) patients and cortical cataract in twelve (12.2%) individuals. In contrast, diabetic patients only experienced posterior polar cataract in seven (7.1%) patients and nuclear sclerosis and PSCC in the remaining eight (8.1%) patients. Conclusions: Diabetic mellitus patients should be checked for PSCC, which can impair vision, particularly in bright light, or during the day
