In the present clinical case, it is an 8-year-old female patient who has been diagnosed with convergence insufficiency. Convergence insufficiency (CI) was defined as one of the most frequent binocular vision problems in daily optometric practice. It has been determined as the inability to obtain or maintain an ideal convergence without effort. CI is the most common binocular vision disorder, it is characterized by muscle coordination problems, where the eyes cannot work together when fixing sight on a certain point, the objective of this clinical case is to demonstrate the effects of insufficient vision. convergence in the 8-year-old female patient. The research focuses on improving the visual quality of the patient, eliminating the discomfort caused by said dysfunction. In the present study, the following optometric tests were performed, such as visual acuity (VA), RX, fundus, near point of convergence (PPC), ocular motility, cover test, among others. Among all the results that were obtained in the study through the diagnostic tests of this clinical case, it was an insufficiency of convergence, the treatment applied will be visual therapy with a training plan for 12 weeks, which is recommended a control every 3 months with the trusted optometrist.In the present clinical case, it is an 8-year-old female patient who has been diagnosed with convergence insufficiency.

La insuficiencia de convergencia es un problema ocular donde los ojos no pueden trabajar juntos cuando se observa un objeto cercano. La Insuficiencia de Convergencia es una afección de la visión, que se da por problemas de coordinación muscular, donde los ojos no funcionan juntos al punto de fijar la vista en un objeto determinado. El objetivo de este caso clínico es conocer las causas de la insuficiencia de convergencia y su efecto en la visión próxima en un paciente femenino de 8 años. Este caso se orienta en mejorar la calidad visual del paciente eliminando los síntomas por la dicha disfunción. En el presente estudio se realizó los siguientes exámenes optométricos como la agudeza visual (AV), RX, fondo de ojo, punto próximo de convergencia (PPC), motilidad ocular, cover test entre otros. Entre todos los resultados que se obtuvieron en el estudio por medio de los exámenes de diagnóstico de este caso clínico, fue una insuficiencia de convergencia, el tratamiento aplicado será, la terapia visual con un plan de entrenamiento durante 12 semanas, el cual se recomienda un control cada 3 meses con el optómetra de confianza.
