Pediatric strabismus is a common eye disease, and most pediatric strabismus occurs mainly in childhood, but it has been found that many adults also suffer from strabismus in childhood. So, what are the causes of pediatric strabismus? The causes of pediatric strabismus: a. Incomplete development of visual function Generally, the visual center of the brain of children is not very well developed, so it can not coordinate well and control the contraction and extension of the external muscles of the eye, so the monovision function of the eyes of children is not stable and sound, at this time any certain external factors such as shock, fever, trauma and other stimuli may lead to the weakening of the unstable eye monovision function or even loss. Second, the pediatric eye factors in general children’s eyes are relatively short, most of the phenomenon of physiological hyperopia. After two years of age, the need to look at near objects slowly increases, and children’s eyes have a strong ability to adjust, and the contraction of the external muscles of the eyes is very good, so if children have the habit of looking at things very close, it will cause both eyes to be highly adjusted for a long time, and then lead to the inward turning of both eyes, which will lead to internal strabismus in the long run. The congenital and birth injury factors Generally, the congenital development of extraocular muscles in children is not too complete; the nerves governing the movement of extraocular muscles are congenitally paralyzed; the mother’s obstructed labor causes damage to the extraocular muscles and extraocular muscles nerves, which can lead to the deviation of eye position. Depending on the type of strabismus, it can be divided into surgical and non-surgical therapies. Surgical treatment involves surgically adjusting the strength and position of the attachment points of the external eye muscles to normalize the eye position. Most congenital internal strabismus and upward and downward strabismus require surgical treatment, and non-adjusted strabismus with a high degree of obliquity usually requires surgical correction. Non-surgical treatment: Not all strabismus requires surgical treatment. If the strabismus is moderate, it can be corrected with appropriate distance glasses or bifocals. If there are also moderate to high refractive abnormalities, glasses are often needed to correct them.
