Abstract: Intermittent exotropia is a common type of strabismus in adolescents. Its unknown pathogenesis and high postoperative regression rate are a hot spot in clinical research. This article reviews the correlation between the postoperative regression and the surgical method, surgical age, preoperative angle of deviation, preoperative refractive power, early postoperative eye position, and combined non-surgical treatment. At present, above factors are controversial about the correlation with postoperative regression. However, early postoperative eye position overcorrection and combined non-surgical treatment can reduce the risk of postoperative regression in intermittent exotropia.(Int Rev Ophthalmol, 2021, 45: 118-123)

Key words: intermittent exotropia, surgical treatment, postoperative effect
