Abstract

Purpose: To obtain an overview of the surgical practices for the management of intermittent exotropia among experienced surgeons.Methods: We conducted a survey of members of the Korean Association for Pediatric Ophthalmology and Strabismus, who had experience of > 15 years in strabismus surgery, via e-mail. Surgical methods for basic-type intermittent exotropia, angle of deviation for determining the surgical dose, reasons for surgical dose adjustment, and the postoperative target angle of deviation were analyzed.Results: Bilateral lateral rectus recession was preferred over unilateral recession and resection for basic-type intermittent exotropia with or without a dominant eye. The preoperative maximum angle of deviation was preferred for determining the surgical dose by 56% of the participants. Two-thirds of the participants preferred to reduce the surgical dose in specific circumstances, lateral incomitancy being the most common reason. In case of true divergence excess-type intermittent exotropia, 47.7% of the participants reduced the surgical dose. The most preferred target angle of deviation at 1 day postoperatively was 11-15 prism diopter esodeviation, as reported by 40% of the participants.Conclusions: Although experienced surgeons had different surgical preferences for intermittent exotropia, a general trend was found. This survey may be a useful reference for beginners in strabismus surgery.

间歇性外斜视手术治疗的探讨
目的:总结经验丰富的外科医生治疗间歇性外斜视的手术方法。方法:我们通过电子邮件对韩国儿童眼科和斜视协会的成员进行了调查,他们在斜视手术方面有150年的经验。分析了基型间歇性外斜视的手术方法、确定手术剂量的偏向角、调整手术剂量的原因、术后目标偏向角。结果:对于有或无主眼的基本型间歇性外斜视,双侧直肌后退优于单侧直肌后退和切除。56%的参与者首选术前最大偏移角来确定手术剂量。三分之二的参与者倾向于在特定情况下减少手术剂量,侧部不适是最常见的原因。对于真正的发散过度型间歇性外斜视,47.7%的参与者减少了手术剂量。术后1天最理想的目标偏差角为11-15棱镜屈光度内偏差,有40%的参与者报告。结论:虽然经验丰富的外科医生对间歇性外斜视有不同的手术选择,但有一个普遍的趋势。这项调查对斜视手术的初学者有一定的参考价值。
