dc.description | Strabismus is the loss of parallelism of the visual axes with impaired binocular vision. Strabismus poses different problems: loss of binocular function, reduced vision in the deviated eye (amblyopia or lazy eye), and unfavorable cosmetic appearance. There is also an alteration in relief vision and precision vision. The primary form leads to amblyopia through the nerve suppression mechanism, which occurs because the brain ignores the images from the deviated eye. Continuous suppression leads to amblyopia, regardless of the angle and cause of the strabismus. The child, under normal conditions, sees objects in space with both eyes, and the brain performs the fusion of both images. To have binocular vision it is necessary that the images perceived with each eye are similar in size, shape, color and intensity and that the balance of the sensory and motor system is perfect. | es_ES |

dc.description.abstract | El estrabismo es la pérdida de paralelismo de los ejes visuales con alteración de la visión binocular. El estrabismo plantea diferentes problemas: la pérdida de la función binocular, la reducción de la visión del ojo desviado (ambliopía u ojo vago) y el aspecto estético desfavorable. También se produce una alteración en la visión en relieve y en la visión de precisión. La forma primaria conduce a la ambliopía a través del mecanismo de supresión nerviosa, que se produce porque el cerebro ignora las imágenes provenientes del ojo desviado. La supresión continua lleva a la ambliopía, independientemente del ángulo y de la causa del estrabismo. El niño, en condiciones normales, ve los objetos del espacio con los dos ojos, y el cerebro realiza la fusión de ambas imágenes. Para tener visión binocular es necesario que las imágenes percibidas con cada ojo sean semejantes en tamaño, forma, color e intensidad y que el equilibrio del sistema sensorial y motor sea perfecto. | es_ES |
