acquired strabismus

Acquired strabismus is an eye condition where the eyes are not properly aligned, meaning they do not look at the same object simultaneously. This misalignment can cause the eyes to turn inward (esotropia), outward (exotropia), upward (hypertropia), or downward (hypotropia). Unlike congenital strabismus, which is present from birth, acquired strabismus develops later in life due to various factors.1

Potential causes include damage to the eye muscles, nerves, or brain centers that control eye movement. Poor vision in one eye can also lead to sensory strabismus. In children, farsightedness (hyperopia) is a common contributor, causing the eyes to cross when trying to focus.1

A significant risk of strabismus, especially in childhood, is the development of amblyopia, or "lazy eye," if not treated promptly. The brain may suppress the image from the deviating eye, leading to reduced vision in that eye. Treatment often involves eyeglasses to correct refractive errors and, in some cases, surgery to realign the eye muscles.12
