Purpose: An investigation of the assessment of dry eye symptoms in individuals with diabetes mellitus. Material & method:A prospective research with 120 patients with diabetes mellitus who were over 30 years old was conducted. Along with an eye and systemic examination, a thorough history was obtained. The ETDRS classification system is used to classify changes in diabetic retinopathy. Fluorescein, Schirmer's test, TBUT, and OSDI of the ocular surface were used to assess the presence of dry eye, which was then categorised as mild, moderate, or severe. A positive result on one or more of the tests was used to make the diagnosis. Results: It was discovered that 50.9% of diabetics had dry eyes. Of them, 17.50 percent had mild dry eyes, 14.20 percent had moderate dry eyes, and 19.20 percent had severe dry eyes. In diabetics, the prevalence of dry eyes was 68.5% for a period of 6–8 years and 85% for a duration of more than 11 years. Conclusion: The severity of retinopathy and the length of diabetes were positively correlated statistically significantly with dry eye. Males and females experience a far higher incidence of dry eye.
