Effect of rectus recession combined with the rear suspension scleral fixation in patients with restrictive strabismus caused by thyroid associated ophthalmopathy

Abstract

AIM: To investigate the therapeutic effect of rectus recession combined with the rear suspension scleral fixation for patients with restrictive strabismus caused by thyroid associated ophthalmopathy(TAO). METHODS: The clinical data of 48 patients(71 eyes)with severe TAO were retrospective analyzed from January 2013 to January 2015.The patients with severe TAO were divided into the exophthalmos(EM)group with 25 patients(35 eyes), compressive optic neuropathy(CON)group with 12 patients(20 eyes)and exposure keratopathy(EK)group with 11 patients(16 eyes).The rectus recession combined with rear suspension scleral fixation treatment was performed in all patients. The visual acuity, clinical activity score(CAS), and diplopia situation of each group were recorded and compared preoperatively and at 6mo postoperatively. RESULTS: The postoperative best corrected visual acuity(BCVA)of the three groups were significantly higher than those before operation(PPPPPCONCLUSION: Rectus recession combined with the rear suspension scleral fixation can help improve the restrictive strabismus caused by TAO, visual acuity, eyeballs to roll back, eliminate the diplopia and to improve the life quality of patients.
