Abstract: 

Purpose: To evaluate the effect of Botulinum toxin-A (BTA) injection into the inferior oblique (IO) muscle in releaving the symptoms of superior oblique (SO) palsy.
Methods: The study was conducted on patients who were referred for acquired SO palsy with less than 2 years of duration. About 10-20 unit of BTA was injected into the belly of the inferior oblique muscle through the inferotemporal quadrant of the involved eye without opening the conjunctiva.
Results: Eighteen eyes from 16 patients were injected. Mean age was 33.7 years and mean duration of paresis was 6 months. Trauma was the cause of paresis in 81.2%. Six months after the injection, mean deviation decreased from 6.4
D to 1.9D; mean IO over-activity decreased from +1.7 to +0.6; mean SO upper-activity decreased from -1.5 to -0.4; mean subjective torsion decreased from 9.30 to 0.40; and mean head tilt decreased from 8.40 to 1.10.
Conclusion: Botulinum toxin-A injection into the IO muscle can decrease the symptoms of patients with SO palsy and cause faster rehabilitation of these patients before stabilization of signs for final decision.
