VALORACIÓN MOTORA PARA DETECTAR INSUFICIENCIA DE CONVERGENCIA EN ESTUDIANTES DE LA ESCUELA DANIEL VILLACRESES DURANTE EL PERÍODO 2019

Abstract

Convergence insufficiency is one of the non-strab dysfunctions of binocular vision 3 in which the eyes tend to deviate outward (exophoria) when performing close-up activities; the symptoms that characterize it are asthenopics. Its classification may be primary, when it occurs due to changes in visual demand at close quarters, lack of sleep or anxiety; and secondary in the case of exophoria / tropia, accommodation problems, paresis or paralysis of the middle rectum, brain injuries or trauma. The present degree work was carried out in order to detect convergence insufficiency by means of a motor evaluation of a sample of 120 children between 6 and 12 years of age from the Daniel Villacreses public school, in the city of Portoviejo., Who met the criteria of inclusion of research. The motor tests that were carried out were the cover test in near vision (40 cm) and in far vision (6 m), near convergence point with real object and light at 40 cm, and positive and negative fusional reserves (40 cm and 6 m). Additionally, a survey was conducted with these students to find out if they had symptoms of this non- strabic binocular dysfunction associated with their close tasks. Through the cover test, near convergence point, positive and negative fusional reserves, it was possible to determine that 46% of the sample did not present any motor problem, while 30% suffered from insufficient convergence and finally 24% reflected having excess of divergence. 48% of the surveyed students did not present symptoms of convergence insufficiency, but there were percentages that justified it, since 17% have loss of concentration, 20% sleep and 15% headaches.
