OBJECTIVE: To determine drug dose and usage of timolol maleate eye drops in the treatment of superficial infantile hemangioma. Methods: A total of 250 superficial hemangioma infants were recruited and assigned into 5 groups (n=50 for each group): an external application group and 4 exterior coating groups (2, 4, 6, 8 times per day). We evaluated the therapeutic effect of different methods for drug application (external application or exterior coating) and the frequency for drug administration on superficial infantile hemangioma. Results: The external application group (twice a day and 0.5 hour per time) showed better effect than that in the exterior coating group with twice a day (P<0.001). The difference in therapeutic effect between the exterior coating group with 6 times a day and exterior coating group with twice a day or with 3 times a day was significant (P<0.001). The differences in drug efficacy were not found among the exterior coating group with 6 times a day, the exterior coating group with 8 times a day, or the external application group with twice a day (All P>0.05). Conclusion: Drug dose may affect the therapeutic effect of timolol maleate eye drops in superficial hemangioma infants, and exterior coating with 6 times a day may achieve the best curative effect.
