Therapeutic options for the management of the early phase of intermittent exotropia are limited. The correction of seemingly insignificant refractive errors might result in better control of the deviation. Patients with hyperopia present an interesting dilemma. Accommodative convergence may be used in uncorrected hyperopia to control exotropia, so it might be anticipated that correction of hyperopia will increase both the frequency and the size of the deviation. This is not always the case. We have all experienced patients with high hyperopia and intermittent exotropia that improved following optical correction. It is postulated that the improvement in visual acuity and, in some cases, the normalization of accommodation might lead to this result.
间歇性外斜视早期治疗的选择有限。矫正看似微不足道的屈光不正可能会更好地控制斜视。远视患者存在一个有趣的难题。未矫正的远视可利用调节性集合来控制外斜视，因此可能预计矫正远视会增加斜视的频率和度数。但情况并非总是如此。我们都遇到过一些患有高度远视和间歇性外斜视的患者，他们在进行光学矫正后病情有所改善。据推测，视力的提高以及在某些情况下调节功能的正常化可能导致了这一结果。
