The main objective of this study was to determine the effects of hypothyroidism on tear film production. This was a descriptive cross sectional study which included 66 patients. Tear film production was measured by filter paper strips. Patients involved in the study was above 18 years to 58 years of age groups. Total 66 patients were included in the study. Out of 66 patients 24 (36.63%) were males and 42(64.68 %) were females. Out of 66 patients 22 (33.3%) patients had age 18 to 30 years and 23(34.8%) had age 30 to 38 years old and remaining 21(31.8%) had age 38 to 58 years. Out of 66 patients in right eye the 12(18.3%) had normal tear film production in right eye and 13(19.6%) had moderate dryness and remaining 41(62.1%) had severe dryness. Out of 66 patients in left eye the 12(18.3%) had normal tear film production in left eye and 13(19.6%) had moderate dryness and remaining 41(62.1%) had severe dryness. It is concluded that there is risk of dry eye in hypothyroidism patients. Medication of hypothyroidism causes dry eye. As a result patients of hypothyroidism mostly have severe dryness due to less tear breakup time.Keywords:
