Strabismus

With strabismus, the two eyes do not align properly. The eyes can be misaligned horizontally, vertically or a combination of both. The "eye turn" may be present constantly or periodically

Strabismus usually occurs at birth (congenital) or in the first few years of life; it can be associated with general disease such as diabetes and high blood pressure. A sudden onset of an eye turn is always something that requires urgent attention. In a very young child, it can lead to permanently reduced vision in one eye and in adults or children it can be a symptom of other serious disease.
 
Your optometrist may recommend treatment options such as eyeglasses, contact lenses, surgery, patching and other therapies based on the individual patient needs. Your optometrist will often arrange for a referral to an ophthalmologist or a family doctor.
