What are the causes of pediatric strabismus? Children’s eye characteristics Causes of pediatric strabismus, children’s eyes are short and all have the phenomenon of physiological hyperopia. As the child’s need to look at near objects gradually increases after the age of 2, and the children’s eyes have a strong adjustment ability and good contraction of the extraocular muscles, if they have the habit of looking at things too close from childhood, so that both eyes often maintain a high degree of adjustment, while inevitably accompanied by too much of both eyeballs turned inward, which is most likely to cause internal strabismus. Congenital factors and birth injuries The causes of strabismus in children are congenital abnormal development of the extraocular muscles; congenital paralysis of the nerves governing the movement of the extraocular muscles; damage to the extraocular muscles and extraocular muscles nerves caused by the mother’s obstructed labor, all of which can result in a skewed eye position. Incompetent development of visual function Causes of strabismus in children, especially infants and young children, the development of the visual center of the brain is not yet perfect, and cannot well coordinate and control the contraction and diastole of the extraocular muscles, so their binocular monovision function is not sound nor stable, and the stimulation of any certain external factors, such as fever, shock, trauma, etc., may make the unstable binocular monovision function weaken or lose, inducing strabismus. The occurrence of strabismus hinders the development of binocular monocular function, thus promoting the development of strabismus and making it more and more serious. children before the age of 5 years old have not developed their visual organs and visual functions, which is the high incidence period of strabismus.
