Extraocular muscle disinsertion outcomes for large angle strabismus
Reviewed by Fiona Rowe

The authors present a case series of patients who underwent surgical extraocular muscle (EOM) disinsertion for severe cranial nerve palsy or thyroid eye disease including 12 patients (13 eyes: 10 male, three female). There was one bilateral case – bilateral sixth nerve palsy – with bilateral medial rectus surgery. Eight cases were unilateral sixth nerve palsy, four thyroid eye disease and one third nerve palsy. Average age was 57.7 years and average preoperative deviation angle was 60PD reducing to 4.6PD postoperatively with a mean 290-day follow-up. Average visual acuity preoperatively was 0.24logMAR right and 0.35 left eye. All had a large reduction in deviation angle but four eyes needed further surgery. There were no serious complications and no overcorrections. The authors report this surgery as efficacious for a specific cohort of patients with severe cranial nerve palsy or thyroid eye disease.
