Aim: The study aimed to assess visual acuity and its impairment among diabetic patients, examining associations with duration of diabetes, smoking history, and the prevalence of ophthalmic complications. Materials and Methods: A cross-sectional study was conducted on 80 diabetic patients aged 30 years and above, diagnosed with type 1 or type 2 diabetes. Visual acuity was measured using the Snellen chart, and a comprehensive ophthalmic examination was performed to detect diabetic retinopathy and other ocular complications. Data on demographic characteristics, medical history, and lifestyle factors were collected through structured questionnaires. Results: Of the 80 patients, 62.5% exhibited visual impairment, with 18.75% having moderate and 18.75% severe impairment. Diabetic retinopathy was detected in 43.75% of patients, while 25% had cataracts, and 12.5% had glaucoma. Visual impairment was significantly associated with longer diabetes duration (p=0.03) and smoking (p=0.04). Patients with over 10 years of diabetes and smokers were at higher risk of visual impairment. Conclusion: The study highlights a high prevalence of visual impairment among diabetic patients, particularly in those with prolonged diabetes and a history of smoking. Regular eye screenings and comprehensive diabetes management, including smoking cessation, are crucial to preventing visual deterioration.
