Abstract
PURPOSE: To supplement limited reports in the literature of the results (outcome)and complications of this procedure with our own recent experience. METHODS: A total of 66 patients with bilateral overaction of the superior oblique and A-pattern strabismus plus 5 patients with a unilateral overacting superior oblique secondary to inferior oblique palsy were treated with a 7 mm silicone expander. RESULTS: The fist group of 66 patients had an average preoperative A-pattern of 39.6 prism diopters with an average correction of the A-pattern from the surgery of 36.3 prism diopters. COMPLICATIONS: Of all 137 operations in these 71 patients, three patients had a sterile orbital cellulitis postoperatively successfully treated with steroids. Also, one patient acquired a Brown's Syndrome-like condition postop'. In these four patients, the sub-Tenon's capsule space had been inadvertently entered during surgery. In addition one unilateral superior oblique palsy occurred postoperatively. CONCLUSION: While this procedure has a very high success rate, special care should be taken with this surgery to avoid entering the sub-Tenon's capsule space.
