Background: Patients with strabismus usually have some degree of disturbance in stereopsis, and there is clear evidence that the treatment of severe amblyopia improves it. However, there are no data reporting grades of stereopsis in patients with amblyopia in absence of strabismus. Objective: To determine and compare the degree of stereopsis in patients without amblyopia, with mild and moderate amblyopia in absence of strabismus who the attended pediatric ophthalmology clinic at Hospital de San Jose between January 2015 and August of 2017.Study design: cross sectional studyMethod: Study design: cross-sectional study. Participants: Patients between 5 and 15 years. Process: The Random Dot Test was used for stereopsis evaluation. The degree of stereopsis between the diff erent levels of amblyopia was compared by means of a Kruskal Wallis test.Results: 119 children were included, 64 did not have amblyopia and 55 had amblyopia. 67.3% were mild (n = 37) and 32.7% were moderate (n = 18). The principal cause was refractive, mild amblyopia 64.9% and moderate 77.8%. Patients between 5 and 10 years had a median stereopsis of 40 seconds of arc regardless of whether they had amblyopia or not, unlike patients older than 10 years in whom as the degree of amblyopia increased, stereopsis decreased.Conclusion: It was observed a tendency to worsen the degree of stereopsis according to the degree of amblyopia although statistical significance was not reached. The early diagnosis and timely treatment of amblyopia during the first years are fundamental to guarantee an adequate visual development of the pediatric population.
