[A comparison of master eye operation with slave eye operation on patients with large-angle exotropia].

Objective: To search for an excellent therapy for patients with large-angle exotropia.

Methods: Strabotomy was performed on the master eyes in the 41 cases (master eye group) and slave eyes in the other 41 cases (slave eye group) with large-angle exotropia (>/= 60(Delta)). The post-operative visual acuity, ocular position, visual function and fixation, the average surgical amount and the frequency of strabotomy were statistically compared between the two groups.
