Yokoyama 술식으로 치료한 근시성 고정사시 1예

다국어 초록 (Multilingual Abstract)

Purpose: To present a surgical result of Yokoyama procedure in myopic strabismus fixus. Case summary: A 51-year-old female patient presented with progressive esotropia and diplopia. According to the Krimsky test, the patient showed 70 prism diopter esotropia and 30 prism diopter hypotropia in her left eye. The axial length was 34.97 mm in the right eye and 33.71 mm in the left eye. The patient was diagnosed with myopic strabismus fixus. The authors performed the Yokoyama procedure on her left eye. Surgical examination revealed each medial rectus muscle was recessed. Half of the muscle bellies of the superior and lateral rectus muscles were sutured together without muscle splitting 15 mm posterior from their insertion. At 1 year postoperatively, the patient showed 30 prism diopter esotropia and 20 prism diopter hypotropia in her right eye by alternative prism cover test. The authors performed the same procedure on her right eye. At 2 months after the second surgery, the patient showed orthotropia in the primary position and gaze limitation was improved. Conclusions: The Yokoyama procedure can be an effective method for improving deviation and ocular motility in esotropia caused by high myopia.
