Objective To analyze the clinical outcomes of superior rectus muscle transposition surgery for the treatment of restrictive horizontal strabismus with limited rotation.Methods A retrospective case series study was conducted.Nineteen patients(19 eyes)with restrictive horizontal strabismus treated at Wuhan University's Affiliated Ai'er Eye Hospital from January 2013 to September 2022 were included.Twelve patients had esotropia,and seven had exotropia.All patients underwent superior rectus muscle transposition surgery.The pre-and postoperative degrees of strabismus and limitation of ocular movement were compared using paired sample t-tests.Follow-up was conducted for six months.Results Among the 19 patients(19 eyes),four eyes underwent superior rectus muscle transposition alone,13 eyes underwent superior rectus muscle transposition combined with recession of the antagonist muscle,and two eyes underwent superior rectus muscle transposition combined with tenotomy of the antagonist muscle.Positive results were obtained in 11 cases of forced duction test.The degree of strabismus decreased from preoperative(88.16△±29.30△)to postoperative(6.74△±1.73△)(t=12.529,P＜0.05).The limitation of ocular movement decreased from preoperative(7.74±0.35)mm to postoperative(4.79±0.86)mm(t=16.836,P＜0.05).None of the 19 patients developed anterior segment ischemia,vertical or torsional strabismus postoperatively,and compensatory head posture disappeared.Conclusions Superior rectus muscle transposition surgery is effective in correcting the primary position of strabismus,improving ocular movement,eliminating compensatory head posture,and achieving satisfactory clinical outcomes for the treatment of restrictive horizontal strabismus with limited rotation.
