Background: Dry eye disease (DED) is a multifactorial disorder of the ocular surface characterized by tear film instability, ocular discomfort, and visual disturbance. Diabetes mellitus is known to affect various ocular structures and has been increasingly associated with dry eye disease due to neuropathy, microvascular damage, and altered tear secretion.

Objective: To determine the prevalence of dry eye disease among diabetic patients attending a tertiary care teaching hospital and to analyze its association with duration and control of diabetes.

Methods: A hospital‑based cross‑sectional study was conducted among adult diabetic patients attending the ophthalmology outpatient department. Detailed history taking, ocular examination, and dry eye evaluation using standard diagnostic tests were performed. Data were analyzed to determine prevalence and associated risk factors.

Results: Dry eye disease was observed in a significant proportion of diabetic patients. The prevalence increased with longer duration of diabetes and poor glycemic control. Mild to moderate dry eye was the most common presentation.

Conclusion: Dry eye disease is a common ocular complication among diabetic patients. Early screening and timely management are essential to improve ocular comfort and prevent vision‑related quality‑of‑life impairment
