Aim: This clinical study aimed to evaluate the prevalence and severity of ocular manifestations in diabetic patients, including diabetic retinopathy, cataracts, macular edema, and glaucoma, to highlight the importance of early detection and management in preventing vision loss. Materials and Methods: A cross-sectional study was conducted in a hospital setting with 80 diabetic patients aged 30 years and above, diagnosed with type 1 or type 2 diabetes mellitus for at least one year. Comprehensive ophthalmological examinations were performed, including visual acuity assessment, slit-lamp biomicroscopy, fundoscopy, and intraocular pressure measurements. Diabetic retinopathy was graded using the Early Treatment Diabetic Retinopathy Study (ETDRS) classification. Data collection included demographic and medical history. Results: Among the 80 patients, 56.25% were males, and 43.75% were females. The majority (32.5%) were aged 51-60 years. Type 2 diabetes was more prevalent (81.25%), with 38.75% of patients having diabetes for over 10 years. Ocular manifestations were common, with diabetic retinopathy present in 40% of patients, cataracts in 25%, and glaucoma in 6.25%. Visual impairment was noted in 50% of patients, and intraocular pressure was elevated in 18.75% of cases. Conclusion: This study highlights the high prevalence of ocular complications in diabetic patients, emphasizing the need for regular eye examinations and effective diabetes management to reduce the risk of vision loss. Early detection of conditions like diabetic retinopathy and glaucoma is critical in preventing progression and preserving vision.
