摘　　要：BACKGROUND Fixed esotropia in high myopia,characterized by irreversible inward ocular deviation and abduction limitation,presents unique therapeutic challenges for athletes requiring precise binocular coordination.The combination of Yokoyama surgery and medial rectus muscle recession has been proposed as an advanced technique addresses both myopia-induced globe displacement and muscular imbalance offering potential advantages over conventional strabismus surgery in this population.AIM To investigate the effects of the modified Yokoyama surgery coupled with medial rectus muscle recession in restoring ocular motility and correcting esotropia among athletes with high myopia and fixed esotropia.METHODS A retrospective study analyzed 30 highly myopia athletes(57 eyes)with fixed esotropia treated at our hospital from January 2022 to April 2024.The participants were allocated into two groups based on the surgical method:The traditional group(n=15,29 eyes)received conventional strabismus surgery,and the combined group(n=15,28 eyes)underwent modified Yokoyama surgery in combination with medial rectus muscle recession.Eye movement improvement,esotropia alleviation,and complications were compared preoperatively and at 1,3,and 6 months post-treatment.RESULTS Both surgical groups exhibited similar baseline scores(traditional:-4.04±0.38 vs combined:-4.12±0.45,P>0.05),showing severe preoperative limitations in ocular motility.Following the intervention,the combined group achieved significantly better outcomes at both 1 month(combined:-2.25±0.28 vs traditional:-2.67±0.32)and 3 months(combined:-1.48±0.28 vs traditional:-1.76±0.43),with statistically significant improvements(P<0.05).However,by 6 months,no significant difference was observed between the two groups(combined:-0.93±0.13;traditional:-1.03±0.18;P>0.05).Prior to treatment,all patients in both groups exhibited a compensatory head posture(CHP).Following treatment,the incidence of CHP decreased to 6.67%in the combined group and 20.00%in the traditional group,both re
