To determine the clinical course of recurrent exotropia after a secondary operation for exotropia.
The surgical results in 58 patients who had undergone reoperation for recurrent exotropia (reoperation group) were retrospectively investigated and compared with those of 100 patients who had undergone primary strabismus surgery only (primary operation group) using survival analysis.
In the reoperation group, recurrence occurred in 19 of the 58 patients (33%). Survival analysis revealed that the recurrence rates in the reoperation group were significantly lower than those in the primary operation group at the same follow-up period after the corresponding strabismus surgery (p=0.018). The distant esodeviation at the postoperative 1st week after reoperation was the only significant factor associated with the recurrence after reoperation (p=0.01).
Exotropia did recur after a secondary operation, although the recurrence rate was lower than that after a primary operation only.
确定外斜视二次手术后复发性外斜视的临床病程。
回顾性研究58例行复发性外斜视再次手术患者（再次手术组）的手术结果，并采用生存分析方法与100例仅接受初次斜视手术患者（初次手术组）的手术结果进行比较。
再次手术组58例患者中有19例（33%）复发。生存分析显示，在相应斜视手术后相同随访期，再次手术组的复发率显著低于初次手术组（p=0.018）。再次手术后第1周的远距离内斜视是再次手术后复发的唯一显著相关因素（p=0.01）。
二次手术后外斜视确实会复发，尽管复发率低于仅初次手术后的复发率。
