|Abstract:||The present study analyses the precorneal teat film using schirmer's test and tear film breakup time (BKUT) in 400 eyes of patients with various types of leprosy. An abnormal tear film BKUT (47.2%) was observed to be much more informative in the present series than the study of schirmer's test alone (25.4%). In patients with lagophthalmos an abnormal tear film BKUT (70%) was higher as compared to an abnormal schirmer's test (40%); while in cases of lagophthalmos with ectropion an abnormal schirmer's test was seen less frequently (26.8%) than in cases of lagophthalmos without ectropion (58.3%). This implied an increase in the aqueous content of the tear film in cases of lagophthalmos with ectropion on the basis of an associated chronic conjunctivitis. Lagophthalmos and ectropion have been identified as additional factors contributing to corneal morbidity. There was a statistically significant difference in the tear film abnormality in different types of leprosy, the maximal difference being in the lepromatous variety.|
