AIM: To analyze the clinical characteristics and treatment of patients with acute acquired concomitant esotropia(AACE)in different refractive status.

METHODS: A retrospective analysis was conducted on 110 patients with non-type I AACE treated from January 2020 to January 2022. The non-myopic group(30 cases, spherical equivalent>-0.5D)and the myopic group(80 cases, spherical equivalent≤-0.5D)were divided according to the refractive status. The degree of deviation, accommodative convergence and accommodation ratio(AC/A), visual function, and surgical methods were observed.

RESULTS: The non-myopic group had no difference in the degree of near deviation \〖(47.13±23.54)^△\〗 and the degree of distant deviation \〖(48.90±22.59)^△\〗(P>0.05); near deviation \〖(40.49±26.09)^△\〗 of myopic group was less than distant deviation \〖(50.09±25.41)^△\〗(P<0.001); and there was no difference in the same distance between the two groups(P>0.05). AC/A in the non-myopic group(5.40±2.23)was higher than that in the myopic group(3.14±3.10; P<0.05). Patients in the myopic group had better near stereopsis than the non-myopic group(P<0.05). The non-myopic group had a variety of surgical methods, while the myopic group mostly used lateral rectus resection or/and medial rectus recession.

CONCLUSION: AACE can occur in different refractive status. Non-myopic patients have the same degree of distant and near strabismus, high AC/A, and varied surgical methods. However, myopic patients have less degree of near deviation than distant deviation and have normal AC/A and better near stereopsis, and lateral rectus resection or/and medial rectus recession are commonly used.
