[The surgical treatment of intermittent exotropia]

77 cases of surgically treated intermittent exotropia were followed up for analysis with regard to the relation between the age of operation and curative effect, the age and post-operative restoration of homologous retinal correspondence, and the effect of over-correction on final orthophoria. The authors were of the opinion that the earliest surgical intervention was conducive to recovery of Grade III visual function and restoration of homologous retinal correspondence, and slight over-correction was significant for final orthophoria. They recommended that the earliest surgical intervention be accorded patients with intermittent exotropia of 20 delta and over, instead of purposeless waiting and observation.
