目的探讨不同类型间歇性外斜视手术治疗的时机及临床疗效。方法回顾性分析72例间歇性外斜视患者的临床资料,患者按年龄分为A组(4～13岁)、B组(14～17岁)、C组(≥18岁)。患者术后随访1年,观察三组术后眼位、双眼视功能恢复、立体视功能恢复情况。结果三组患者术后立体视功能恢复、双眼视功能恢复与手术年龄、术前有无融合功能密切相关,有融合功能者,术后正位率较高;无融合功能者正位率较低;年龄越小,立体视功能恢复率较高。结论间歇性外斜视术前融合功能对术后眼位影响较大,早期手术有利于双眼视功能的恢复。
Objective To investigate the timing and clinical effects of different types of intermittent exotropia surgery. Methods The clinical data of 72 patients with intermittent exotropia were retrospectively analyzed. Patients were divided into A group (4- 13 years), B group (14-17 years) and C group (≥18 years). The patients were followed up for 1 year. The three groups were followed up for ocular position, binocular visual function recovery and stereopsis recovery. Results Three groups of patients with postoperative recovery of stereopsis, binocular visual function recovery and surgical age, preoperative fusion is closely related to the fusion function, postoperative orthographic rate was higher; non-fusion positive rate was lower ; Younger, stereoscopic visual function recovery rate higher. Conclusion The preoperative fusion function of intermittent exotropia has a great influence on the ophthalmic position after operation. Early surgery is beneficial to the recovery of binocular visual function.
