Abstract:
Objective To observe the effectiveness of botulinum toxin A (BTXA) in the treatment of small sample patients with acute acquired concomitant esotropia. Design Retrospective case series. Participants 6 patients (3 female and 3 male) with acute acquired concomitant esotropia aged 6 to 34 years. Methods All the patients were received 2.5 units of BTXA injected into the bilateral medial rectus muscles once under electromyographic control. They were performed alter prism-cover test,synoptophore and stereoscopic charts test. Main Outcome Measures The alignment of eyes and binocular vision. Results The follow-up of patients was 4 to 39 months. The pre-injection angle of deviation was 43.3?1.0△; the angle of deviation at the last follow-up was 3.3?8.2△,and 5 patients achieved alignment. In pre-injection,one patient had distance stereopsis,2 patients had near stereopsis with 600 seconds and 40 seconds; after injection,5 patients demonstrated distance and near stereeopsis (3 patients 40 seconds,1 patient 60 seconds,and 1 patient 200 seconds). Conclusion This small sample study shows that BTXA injection is effective alternative in treating acute acquired concomitant esotropia.
