Eye Care Basics Amblyopia (Lazy Eye) Causes Amblyopia, or lazy eye, is a loss of vision or lack of development of central vision in one eye caused by inadequate use during early childhood. Amblyopia may develop from conditions such as, a squint or strabismus (eyes not positioned straight), congenital cataract, uncorrected high near-sightedness (myopia) or far-sightedness (hyperopia) in one eye or both eyes and severe ptosis (droopy eyelids).
Symptoms While symptoms are not always obvious, they typically appear during early childhood and may include: • Noticeably favoring one eye • Eye turning in, out or up • Closing of one eye • Squint • Headaches or eyestrain
Diagnosis and Treatment Comprehensive eye exams during early childhood are highly recommended and can lead to the diagnosis of ablyopia at an early age increasing the chance for a complete recovery. The most effective treatment is to encourage the use of the ablyopia eye, which may include using a combination of prescription lenses, prisms, vision therapy and eye patching.
