Purpose: To assess the influence of type 1 diabetes on tear film and to quantify the vision problems and glycosylated hemoglobin link to diabetes mellitus in this study.

Methodology: This cross sectional study was conducted after obtaining ethical approval. Patients who were known to have diabetes mellitus for at least 5 years were included in study while those diagnosed with diabetes mellitus for less than 5 years were excluded. A self-designed Performa was used to gather the data that mainly included history of ocular and systemic disease, age, duration of diabetes, level of HbA1c test result, medications. Tear film was assessed with Schirmer strips instilled in both eye for five minutes with eyes closed. Later it was viewed using fluorescence strips after the topical anesthetic was given then studied using the cobalt blue filter on slit-lamps. When it came to entering and analyzing the data, we used IBM SPSS Version.

Results: Patients with value of moderate HbA1c with percentage of 52.3% were higher than both mild and high values. There was significant relationship between HbA1c value and dry eye according to tear breakup time test with values severe are more than both who has values moderate and mild.

Conclusion: Type 1 diabetes mellitus and dry eyes are shown to be closely linked in this research. Tear producing layer is affected by the incidence of disease and the higher HbA1c level.
