Aim: To assess of refractive error, and AC/A ratio among esotropic school-aged children Materials and Methods: This descriptive, cross-sectional hospital based study, was conducted at Alwalidein eye hospital Omdurman locality in Sudan, and included all patients who attended binocular vision clinic in period between October 2018 and April 2019. The examination included assessment of vision, visual acuity, refractive status of the eye, binocularity, outer eye, ocular motility, angle and constancy of deviation, and measurement of AC\A ratio. Statistical analysis was carried using statistical program for social studies (SPSS 20) software. Results: The study included 100 Esotropic subjects, 53(53%) were males and 47(47%) were females, their age ranged between (6-17) years with a mean of 8.75 ±3.11 years. Most of the Esotropic patients fall within (less than 8years). Vast majority of subjects had reduced visual acuity representing (83.0%) at right eye and (84.0%) at left eye. (55.0%) of the subjects had normal ocular motility that resulted in large percent (24.0%) of subjects were alternating Esotropes. Large number of subjects of constant esotropia (13.0%) had marked angle. Revealed that most common type of refractive error associated with esotropia was hypermetropia representing (57.0%), followed by astigmatism (34. 0%), and myopia (9.0%). (63.0%) of subjects had high AC/A ratio. Conclusion: the study concluded that hypermetropia was the most common type of refractive error associated with the incidence of esotropia, and most of subjects had high AC\A ratio.
