STRABISMUS Causes Extra ocular muscles: This is the 6th muscles of the eye that attaches to the outside of each eye responsible for eye movement. The other 4 muscles are responsible for vertical, horizontal and angular movement. Strabismus can be caused by a brain disorder that is unable to coordinate the eyes or a muscle disorder where one muscle fails to do its function. What is strabismus? Treatment Strabismus is a disorder commonly known as crossed eyes or walleyes. An individual with strabismus has difficulty aligning both of their eyes. This can be classified as bilateral, unilateral or alternating. Bilateral: Both Eyes Unilateral: One Eye Alternating: Alternating eyes where one is focused and one is not. Treatment includes: Glasses Eye exercise to strengthen the weak eye muscles Surgery Eye Patch: A patch that covers the strong eye encouraging the weak eye to strengthen the muscles. Prisms: Modifies the way light and an image is in the eye. Eyes can also be classified in the direction they turn: Esotropic Strabismus: Eyes that turn inward towards the nose. This is the most common form of strabismus and have a onset by the age of 6 months. This type of strabismus will usually worsen with age. Exotropic Strabismus: Eye that turn outward away from the nose. This type will usually require surgery, but some cases can be treated with glasses. Children with this type of strabismus tend to squint their eyes in the sun. The degree of turn in the eye is more when looking at objects in a distance. Hypertropic Strabismus: This is where one eye turns up and one eye turns down. This type can exist with other types of strabismus. Surgery Surgery will attempt to realign the eyes as close to normal as possible. A adult can expect to receive near perfect alignment and improved depth perception. A child will never regain perfect alignment, because the brain is responsible for vision. A child with strabismus will have an underdeveloped portion of the brain. This is called amblyopia.

It is estimated that 5% of children have some form of strabismus. Initially children may have double vision, but sometimes the brain will disregard the vision of one eye called, suppression. In many cases a child’s signs and symptoms are shown at birth or shortly after. This is called congenital strabismus. Acquired Stravismus: Adults can also develop strabismus from an injury to the eye orbit, health problems or a family history of strabismus can be a risk factor.
