PROANO MOSQUERA, Gabriela  y  DE JESUS ARTEAGA SEGARRA, Mariana. Visual chromatic alteration by neurotoxics in patients of 20 - 40 age. Vive Rev. Salud [online]. 2021, vol.4, n.10, pp.44-52.  Epub 30-Abr-2021. ISSN 2664-3243.

The study seeks to determine the alterations of color vision by neurotoxic people in patients aged 20 to 40 years in the Czech parish - Ecuador and which of them generates greater vulnerability in the photoreceptor nerve cells of the retina.

Materials and methods.

An evaluative-descriptive study of tests was carried out in which 54 people between the ages of 20 and 40 who belong to the accelerated high school social program participated and the clinical history of detection was applied to them to determine if they were within the inclusion criteria. To the 54 patients who fulfilled the requirement, apart from the complete visual examination, the Farnsworth test was applied, which is the most accurate and complete test for the diagnosis of the different color vision alterations.


When performing the data tabulation, it is observed that the most frequent chromatic alteration is deuteranomaly, and that the most neurotoxic agent for retinal photoreceptor cells is alcohol, affecting mainly the male population between 31 and 35 years of age. The second most aggressive neurotoxic is cigarettes, affecting the same population.


It is determined that neurotoxic agents directly affect the damage of specialized photoreceptors to color, the damage may be imperceptible at first, but it can affect the patient mainly in work development, which is when the patient realizes that he is presenting a chromatic alteration, decreasing the exposure to them, can reverse the damage if the frequency has not been prolonged.
