Strabismus; disorder of the eye, causes and treatment

Strabismus (Crossed Eyes) Strabismus (crossed eyes) is a condition in which one eye is turned in a direction that is different from the other eye. Treatment may include glasses, patching, eye exercises, medication or surgery. What is strabismus (crossed eyes)? Strabismus (crossed eyes) is a condition in which the eyes do not line up with one another. In other words, one eye is turned in a direction that is different from the other eye. Under normal conditions, the six muscles that control eye movement work together and point both eyes at the same direction. Patients with strabismus have problems with the control of eye movement and cannot keep normal ocular alignment (eye position). Strabismus can be categorized by the direction of the turned or misaligned eye: Inward turning (esotropia) Outward turning (exotropia) Upward turning (hypertropia) Downward turning (hypotropia) Other factors to consider that help determine the cause and treatment of strabismus: Did the problem come on suddenly or over time? Was it present in the first 6 months of life, or did it occur later on? Does it always affect the same eye, or does it switch between eyes? Is the degree of turning small, moderate, or large? Is it always present, or only part of the time? Is there a family history of strabismus? What are the types of strabismus? There are several forms of strabismus. The two most common are: Accommodative esotropia: This often occurs in cases of uncorrected farsightedness and a genetic predisposition (family history) for the eyes to turn in. Because the ability to focus is linked to where the eyes are pointing, the extra focusing effort needed to keep distant objects in clear focus may cause the eyes to turn inward. Symptoms include double vision, closing or covering one eye when looking at something near, and tilting or turning the head. This type of strabismus typically starts in the first few years of life. This condition is usually treated with glasses, but may also require eye patching and/or surgery on the muscles of one or both eyes. Intermittent exotropia: In this type of strabismus, one eye will fixate (concentrate) on a target while the other eye is pointing outward. Symptoms may include double vision, headaches, difficulty reading, eyestrain, and closing one eye when viewing far away objects or when in bright light. Patients may have no symptoms while the ocular deviation (difference) may be noticed by others. Intermittent exotropia can happen at any age. Treatment may involve glasses, patching, eye exercises and/or surgery on the muscles of one or both eyes. Another type of strabismus is called infantile esotropia. This condition is marked by a large amount of inward turning of both eyes in infants that typically starts before six months of age. There is usually no significant amount of farsightedness present and glasses do not correct the crossing. Inward turning may start on an irregular basis, but soon becomes constant in nature. It is present when the child is looking far away and up close. The treatment for this type of strabismus is surgery on the muscles of one or both eyes to correct the alignment. Adults can also experience strabismus. Most commonly, ocular misalignment in adults is due to stroke, but it can also occur from physical trauma or from a childhood strabismus that was not previously treated or has recurred or progressed. Strabismus in adults can be treated in a variety of ways, including observation, patching, prism glasses and/or strabismus surgery. How common is strabismus? It is estimated that four percent of the U.S. population, or about 13 million people, have strabismus. watch previous video on VAGUS NERVE👇🏾👇🏾👇🏾👇🏾🔥❤    • The Vagus Nerve Anatomy, Course and supply...   SUBSCRIBE TO OUR CHANNEL❤ #Strabismus #esotropia #exotropia #hypotropia #hypertropia
