Abstract

Introduction: Healthy vision requires three basic processes: image formation on the retina, stimulation of cones and rods, and conduction of nerve impulses. Ametropia is an inadequate focusing of the retina. A large part of the world population suffers from ametropia.

Objective: To determine the frequency of ametropia in medical students of FCM UNA, 2018.

Methodology: Cross-sectional analyti- cal observational study. Non-probabilistic convenience sampling. Instruments: closed questionnaires, variables of own elaborati- on. Chi-square was used for data analysis and a p value of less than 0.05 as significant.

Results: 66.3% of the sample presented some type of ametropia and 43% of these were diagnosed in adolescence. Simple myopia was dominant, being present in 80.44% of the ametropic patients. Ninety-nine percent of the sample reported having habits associated with the appearance of ametropia and 82% had relatives with ametropia.

Discussion: According to the data collected, the factors associated with the appearance of ametropia (habits and family history) do not provide significant data that affirm their association with the onset of the pathology. However, we can affirm that most of the population studied presents ametropia of various types that could be multiple in the same individual.
