OBJECTIVE: To evaluate the results of the treatment with botulinum toxin in the correction of restrictive strabismus and compare them with those of the surgery, in cases affected by similar strabismus severity. METHOD: A prospective, descriptive and comparative study was made in 10 patients with strabismus from May, 2006 to February, 2009, which were treated with botulinum toxin directly injected into the affected muscle. These results were then compared to those of the surgery performed in 10 cases. RESULTS: Age, the predominant sex, the time of evolution and the clinical severity of strabismus were comparable in both groups. The botulinum toxin results were satisfactory in 70 % of cases treated with toxin and surgery. The average values of the prismatic dioptries of both eyes lowered at 7th, 45th and 90th days. The differences among the average values of the corrected prismatic dioptries in both types of treatment were not significant. CONCLUSION: The treatment with the botulinum toxin is less invasive than the surgery.
