Amblyopia is one of the alterations that causes the greatest impact and is frequent in the loss of visual acuity, mainly in children; its prevalence varies between 2% and 7%. On the other hand, it is the first cause of vision impairment in adults. Objective. To analyze the prevalence of non-strabismic amblyopia in different age groups in Latin America. Methodology. A systematic review of studies conducted within the period 2014 to 2021 was performed in databases such as: Redalyc, Scielo, Medilib, Dialnet and Google Scholar. The analysis of five relevant studies in Colombia, Ecuador, Nicaragua, Chile and Cuba is presented. Conclusion. In the Cuban study, amblyopia was found in 1.39%; in Colombia, 8.10%; in Ecuador, 5.30%; in Nicaragua, 2.9%; in Chile the incidence was 2.41%, 2.55% and 3.51%, respectively for the age groups 18-38 years, 39-59 years and 60-79 years. Thus, Colombia is the country with the highest incidence of amblyopia (8.10%), and Cuba the lowest with 1.39%. In addition, refractive amblyopia is the most common in the studies and as for gender, there are no differences. Studies on non-strabismic amblyopia are scarce at regional or world level on this subject, so the present analysis is relevant in this area of knowledge. In addition, the information presented contributes to make visible the need to promote examinations that allow an adequate and timely diagnosis and treatment.
