Eye muscle surgery.
In the past year experimental studies have analyzed the ease with which specific sutures can be adjusted, have investigated ways to prevent adhesions in animal models, and have studied variations of the inferior oblique at the surgical capture site. Our knowledge of rectus extraocular muscle pulleys continues to improve, and the value of botulinum toxin type A in the treatment of several conditions has been further documented. New surgical techniques include slanted recessions of the lateral rectus muscles, combined monocular resection and bilateral anterior transposition of the inferior oblique, and intraoperative use of acetylcholine during inferior oblique myectomy. Favorable results have been reported after clinically important modifications to the superior oblique muscle silicone expander and anterior transposition of the inferior oblique procedures, as well as after bilateral inferior rectus muscle recession in dysthyroid ophthalmopathy. Conjunctival inclusion cysts, anterior segment ischemia despite microvascular dissection, and corneal topographic changes are reported as complications occurring after strabismus surgery. Recent publications discussing these issues are reviewed here.
