Ocular Complications of Strabismus Surgery
Abstract: Background: To evaluate ocular complications of strabismus surgery at the Department of Strabismus and Neuroophthalmology in our clinic. Methods: The medical records of patients who underwent strabismus surgery between March 1999 and February 2013 were retrospectively reviewed. Patients with minor ocular complications such as wound irregularities, conjunctivitis, subconjunctival hemorrhage, and less than six-month follow-up periods were excluded from the study. Employed strabismus surgeries included recessions, resections, muscle advancements, inferior oblique myectomies, and muscle transpositions. Results: Our case series are comprised of 1468 patients who underwent strabismus surgery. The ages of the patients ranged from 6 to 80 years. Recognized primary ocular complications were noted in eight patients (0.5%). Scleral perforation with retinal break was observed in one myopic patient during retrobulbar anesthesia. Medial rectus rupture occurred during medial rectus recession in one patient with chronic complete sixth nerve palsy. Conjunctival cyst occured postoperatively in one patient with partially refractive accommodative esotropia who had bilateral medial rectus recession. Corneal dellen developed postoperatively in five patients with exotropia. Conclusion: Ocular complications of strabismus surgery are usually treatable. Damage to ocular structures can be prevented by meticulous surgical approach. Close postoperative follow-up is required in all cases.
