PURPOSE: To evaluate a procedure to prevent lower eyelid retraction, which may occur after inferior rectus muscle recession surgery as a direct consequence of the intimate anatomic connections between the inferior rectus muscle and lower eyelid retractors. METHODS: We evaluated the technique of primary infratarsal lower eyelid retractor lysis on 12 eyelids of ten patients undergoing inferior rectus muscle recession of 3 mm or more. Indications for surgery included restrictive strabismus related to Graves' ophthalmopathy, orbital blowout fracture, and orbital fibrosis syndrome. RESULTS: For the 12 eyes, inferior rectus muscle recession ranged from 3 to 10 mm (mean, 5.3 mm). Postoperatively there was no significant change in mean lower eyelid position (P > .82), and no patient developed inferior scleral show. CONCLUSION: Primary infratarsal eyelid retractor lysis is an effective technique for preventing lower eyelid retraction after inferior rectus muscle recession strabismus surgery.
