Abstract: 【Abstract】 Restrictive strabismus which due to thyroid associated ophthalmopathy (TAO) is challenging to a surgeon as well as related medical team. With help of optometrist or orthoptist, Fresnel prism can be used at active stage. Usually surgery should be scheduled at least 6 months after the deviation becomes stable, unless high intraocular pressure or visual field defect was detected. Surgical release of surrounding fibrotic tissue (both orbit side and globe side) should be done thoroughly before the muscle recession. Mild under-correction right after the surgery is suggested in most cases, except restricted hypertropia. In terms of long term result, most patients achieved single vision at primary and down gaze. Even though some prophylactic approach had been applied during the inferior rectus recession, post-operation lower lid retraction still occurred occasionally, which require further study.
