This work, entitled Prevalence of Ametropia in School Age, was the first epidemiological profile of refractive errors in Colombia and it evaluated a population with characteristics very similar to ours, which is an important aspect for the comparison of both studies, added to the interesting factor of the difference in time and the changes that this could bring.

Patients with apparent corneal pathology on examination, contact lens wearers, high ametropia of more than -6 or +6 diopters (D), and history of corneal pathology or previous eye surgery were excluded from the study.
Since the ocular globe size and the retinal structure differ between humans and animals, the same amount of ametropia could also provide different visual effects and have some impact on animal behavior.
Glaucoma during infancy is one of the leading causes of blindness in childhood.[sup][9] The goal of preserving a lifetime of vision for these children involves early, prompt control of IOP, correction of ametropia, and rigorous amblyopia treatment.[sup][10] In the current case series, the efficacy in terms of IOP control and the safety of trabeculotomy within 4 weeks of birth were evaluated in treating PCG.
