| dc.description | Protanopia is the optical deficiency caused by the absence of the cones, the person suffering from this rare condition has a loss of sensitivity to light at the red end of the color spectrum, particularly that it derives from color blindness, it can be hereditary from parents to children. through the chromosomes. Worldwide, Protanopia develops more in males by 8% (640 million approx.) than in females with 0.5% (40 million approx.). The present case study was carried out on a 22-year-old male patient, who came to the clinic indicating that he had difficulty identifying a certain color, in addition he had a headache in the occipital part, visual fatigue in both eyes, blurred vision when observing a color. remote object. Optometric examinations were carried out, such as the measurement of visual acuity both from a distance and from near with and without correction, eye fundus, Ishihara test and Farnsworth test, which allowed us to observe that our patient presents a refractive error and a certain color vision deficiency. The treatment provided was optical correction through the use of glasses with negative spherical lenses and the additional application of a green color filter. In conclusion, a visual control will be improved every 6 months to find out how the contrast of red objects has improved and to see if there are changes in its graduation and make the proper correction for better visual acuity. | es_ES |

| dc.description.abstract | La Protanopia es la deficiencia óptica ocasionado por la ausencia de los conos, la persona que padece esta rara afección tiene una pérdida de sensibilidad a la luz en el extremo rojo del espectro de colores particularmente que se deriva del daltonismo puede ser hereditario de padres a hijos a través de los cromosomas. La Protanopia a nivel mundial se desarrolla más en las personas de sexo masculino en un 8% (640 millones aprox.) que en el sexo femenino con un 0.5% (40 millones aprox.). El presente estudio de caso se realizó en un paciente masculino de 22 años edad, que acude a consulta indicando que tiene dificultad para identificar cierto color adicionalmente ha presentado dolor de cabeza en la parte occipital, fatiga visual en ambos ojos, visión borrosa al observar un objeto a distancia. Se realizo exámenes optométricos como podemos mencionar la medición de agudeza visual tanto de lejos como de cerca con y sin corrección, fondo de ojo, test de Ishihara y el test de Farnsworth, los cuales nos permitió observar que nuestro paciente presenta un error refractivo y cierta deficiencia en la visión cromática. El tratamiento proporcionado fue la corrección óptica mediante el uso de anteojos con lunas esféricas negativas y adicional la aplicación de un filtro de color verde. En conclusión, se recomendó un control visual cada 6 meses para saber cómo ha mejorado su contraste de los objetos rojos y ver si existen cambios en su graduación y hacer la debida corrección para una mejor agudeza visual. | es_ES |
