目的 探讨影响间歇性外斜视远期疗效的因素。方法 对107例手术治疗的间歇性外斜视,按年龄、术式、斜视类型、融合功能、非自主性辐辏功能强弱分组观察其疗效。随访2～10年,平均2.8年。结果 107例眼位:正位85例(79.44%),外斜14例(13.88%),内斜8例(7.48％);眼位正位率与年龄、术式、斜视类型均无相关性(P>0.05),而与术前有无融合功能有关,井与非自主性辐辏的强弱有关(P<0.01);非自主性辐辏功能较差或术前无融合功能者眼位回退率较高(P<0.05);眼位过矫率与上述诸因素无关。双眼视功能:年龄越小,立体视功能恢复率越高(P<0.01)。A-V征全部消失。结论术前融合功能和辐辏功能对术后眼位有较大影响,早期手术有利于双眼视功能的恢复。
Objective To discuss the factors that influence the long-term postoperative effect in patients with intermittent exotropia. Methods 107 patients with intermittent exotropia were divided into groups according to age,type of operation,type of strabisumus,presence of fusion and amplitude of involuntary convergence and the curative efect were compared, Results The follow up time was from 2 years to 10 years, average 2.8 years. The postoperative eye positions were orthophoria in 85 cases (79%),exotropia in 14 cases (13%) and esolropia in 8 cases (8%). The orthophoric rate did not correlate with age,type of operation,type of strabismus ( P < 0.05) ,but with preoperative presence of fusion and amplitude of involuntary convergence ( P < 0.01) . The undercorrection rate of the patients who had not fusion function and have insufficiency involuntary convergence before operation was high ( P < 0.05) .The overcor-rection rate was not related to these factors. The younger patients were, the higher the recovery rate of their stereoscopic vision was ( P < 0.01). All A - V syndrome disappeared. Conclusion The preoperative presence of fusion and amplitude of involuntary convergence of the patients with intermittent exotropia have quite an effect on their postoperative eye position. Earlier operation is in favor of the recovery of binocular vision.
