Abstract

Objective The purpose of this study was to evaluate the effect of treatment of amblyopia in the control of intermittent exotropia. Background Intermittent exotropia X (T) is a common form of childhood exotropia, accounting for about 50%–90% of all the exotropia and affecting about 1% of the general population. Methods This nonrandomized, prospective study was conducted in the Ophthalmology Department, Menoufia University Hospital from December 2018 to March 2020 on 50 patients of both sexes diagnosed with amblyopia and X (T) who were divided into three groups: group A: 20 patients who had bilateral amblyopia had been given spectacles. Group B: 13 patients who had insignificant refractive errors had been given part-time patching of the sound eye. Group C: 17 patients who had unilateral amblyopia with significant refractive errors had been given spectacles and part-time patching of the sound eye. Results Amblyopia improved in 90% of cases. From the improved cases, near and far angles of strabismus were insignificantly improved after 3 and 6 months of treatment. Office control was significantly improved after 3 and 6 months of treatment. Conclusion Treatment of amblyopia in cases of X (T) may improve the control of X (T) but it seems that it does not affect the angle of strabismus.
