strabismus
Sign in to saveStrabismus is an eye disorder in which the eyes do not properly align with each other when looking at an object. The eye that is pointed at an object can alternate. The condition may be present occasionally or constantly. If present during a large part of childhood, it may result in amblyopia ("lazy eyes") and loss of depth perception. If onset is during adulthood, it is more likely to result in double vision.
AI overview
Strabismus is a condition where the eyes don't align properly with each other when focusing on an object, and either eye may be the one pointed at the target. It matters because when present during childhood, it can lead to amblyopia (lazy eye) and loss of depth perception, while adult-onset strabismus typically causes double vision.

Strabismus is an eye disorder in which the eyes do not properly align with each other when looking at an object. The eye that is pointed at an object can alternate. The condition may be present occasionally or constantly. If present during a large part of childhood, it may result in amblyopia ("lazy eyes") and loss of depth perception. If onset is during adulthood, it is more likely to result in double vision.
Strabismus can occur out of muscle dysfunction (e.g., myasthenia gravis), farsightedness, problems in the brain, trauma, or infections. Risk factors include premature birth, cerebral palsy, and a family history of the condition. Types include esotropia, where the eyes are crossed ("cross eyed"); exotropia, where the eyes diverge ("lazy eyed" or "wall eyed"); and hypertropia or hypotropia, where they are vertically misaligned. They can also be classified by whether the problem is present in all directions a person looks (comitant) or varies by direction (incomitant). Another condition that produces similar symptoms is a cranial nerve disease. Diagnosis may be made by observing the light reflecting from the person's eyes and finding that it is not centered on the pupil. This is known as the Hirschberg reflex test.
