单侧内直肌前徙和外直肌后徙在小角度继发性外斜视手术治疗的应用
Unilateral medial rectus advancement and lateral rectus recession are used for the surgical treatment of exotropia secondary to small angles
摘要
Abstract
Objective To evaluate the surgical dose-effect relationship between patients with small-angle oblique who underwent unilateral medial rectus advancement and lateral rectus posterior migration in patients with secondary exotro-pia due to common esotropia after postoperative transfer of lateral rectus muscles,respectively.Methods A retrospective analysis was performed for 34 patients with small-angle secondary exotropia who underwent unilateral or bilateral medialrec-tus regression surgery for common esotropia.Patients should be followed up for at least 6 months after surgery.Results 23(23/34,67.65％)performed medial rectus anterior migration(group Ⅰ),11(11/34,32.35％)routine rectus regression surgery(Group Ⅱ).The average preoperative near and distant angles in group Ⅰ were 23.26±5.96 PD and 23.26±5.96 PD,respectively,and in group Ⅱ were 20.45±4.16 PD and 22.73±5.18 PD,respectively.At the end of follow-up,the orthophoria rate of the Ⅰ group was 73.91％(17/23)and that of the Ⅱ group was 63.64％(7/11)(P＞0.05).The mean of the dose-response relationship was 3.89±0.71 PD/mm in Group Ⅰ compared to 2.7 0±0.52 PD/mm in GroupⅡ.Conclusions In the group of exotropia secondary to small degree deviation angle,medial rectus anterior migration and lateral rectus posterior migration can effectively correct the deviation,and there is no significant difference in statis-tics.Medial rectus advancement has a higher dose-response relationship than lateral rectus recession in secondary exotropia,and anterior medial rectus migration has advantages in long-term postoperative management.关键词
