Illustration of esotropia, a form of strabismus where one or both eyes turn inwards. The condition may be present from birth (congenital esotropia), develop within the first two years (infantile esotropia), or occur later in life secondary to another condition (acquired esotropia), especially due to farsightedness (accommodative esotropia). Treatment depends upon the underlying cause, but may include glasses, botox injections to the eye muscles, or surgery.
