What is the fourth nervous palsy?
The fourth nervous palsy concerns a congenital defect or the fourth skull injury, which is responsible for eye movement. When the nerve is damaged or malformed, the excellent oblique muscle in the skull behind the eye cannot keep it directly forward. The affected eye tends to drift vertically, horizontally or both from the center, causing double vision that can only be released by tilting the head to one side. Relaxation and self -confidence in the problem can significantly disrupt the ability of a person to engage in everyday tasks. Surgery is usually required to repair the eye location and minimize visual tension.
Most of the fourth nervous palsy cases are the result of developmental abnormalities in pregnancy. The causes of congenital palsy are not well understood and there are no clear connections between the palsy and the use of the mother's drugs, diet or other environmental factors. When the fourth nervous advocate develops later in life, it is usually due to the head injury of the head after falling from a height or with a high impact of a car accident.The condition may be either one -sided or limited to one side or bilateral affecting both eyes. Most cases of congenital and acquired fourth nervous palsy are unilateral.
The deviation of the eye from the central alignment is pronounced in some people and in others it is very fine. If the eye does not seem to be balanced, the primary feature of the fourth nervous polio tends to tilt the head to one side. An infant or a child can be observed, for example, to tilt the head to compensate for distorted double vision. The tilt of the head is usually consistent with unilateral palsy, although a child with bilateral problems can often adjust his head to try to balance vision.
The physician may diagnose the fourth nervous palsy in the infant by assessing the physical appearance of the eye and determine the degree of the head. Imaging scanning and electroencephalogrames can also be searched to seek abnormalities in the muscles, nervesAll of them and other structures in the skull. The victims of accidents are evaluated similarly either before or after treatment of other injuries. After confirming the diagnosis, a team of doctors and surgeons can discuss treatment options.
In most cases, a severely damaged or non -functional nerve cannot be corrected. Instead, the surgical repair is aimed at adjusting the tightness of the superior oblique muscle. The surgeon can interrupt the muscles and re -insert it down to the eye to help attract the organ into a better alignment. After successful surgery, the tilting of the head and central vision improves significantly.
