Abstract： AIM: To evaluate the effects induced by topical antiglaucomatous drugs, Travoprost eyedrops on tear film. <br> METHODS: Eighteen patients ( 32 eyes ) with primary open-angle glaucoma or ocular hypertension were all treated with Travoprost eyedrops once every night. The symptom score, Schirmer's test ( S Ⅰ t ) , corneal fluorescein staining ( FL ) , tear film break - up time (BUT), were observed before the treatment and 1, 2 and 3mo after the treatment. <br> RESULTS: The average symptom score, FL of all patients were 1. 34 ± 1. 56 and 0. 44 ± 0. 73 before the treatment, and 2. 75±1. 63, 1. 08±0. 84; 5. 10±1. 68, 1. 53±0-67;6. 33±1. 40, 1. 98±0. 50 respectively after 1, 2 and 3mo of the treatment. There was significant increase in symptom score and FL after the treatment for 1, 2 and 3mo (P=0. 00). The average BUT, SⅠt of all patients were (7. 76±0. 92s), (8. 47±2. 73mm/5min) before the treatment, and (7. 08±1. 15s), (7. 73±3. 44mm/5min);(5-59±1. 33s), (6. 82±3. 05mm/5min); (4. 29±1. 87s), (6-04±3. 15mm/5min) respectively after 1, 2 and 3mo of the treatment. There was significant decrease in BUT and ST after the treatment for 1, 2 and 3mo (P=0. 00). <br> CONCLUSION: Travoprost eyedrops can obviously aggravate patients’ corneal irritation after treatment. Our results show abnormal decreased tear secretion and stability of tear film induced by Travoprost eyedrops over the short term.
