The mean duration of suffering was 20 months. Each patient reciveved 120 IV of BTA.The results of BAT injection were classified as: excellent result (an improvement of more that 75%) in 45% a good response (an improvement of 25%-50%) in 15% and a minimal or no resrponse in 5%. The efficacy of BTA injection lasted 2-3 months. and more often needed to reoeat the injections (12 patients ).These patients follow up for 1 years after last injection; there were not seen recurrence of symptoms in most of them.Conclusion: BTA injection is a simple and effective out-patient treatment for patients with blepharospasm.
