Strabismus is defined as a condition when the eyes are not aligned because of lack of coordination of the extraocular muscles. It is sometimes called as "squint" or "lazy eyes". Strabismus is normal in the young infant but should disappear after around age 4 months.
The most cause of strabismus come from the muscle imbalance or paralysis of extraocular muscles, however it also may result from brain tumor, myasthenia gravis, or infection.
Signs and Symptoms of Strabismus:
Amblyopia (it comes if not treated early)
Loss of binocular vision
Permanent loss of vision if not treated early
Impairment of depth perception
Squinting or tilting of the head to see
Frequent headaches
Nursing Interventions:
Instruct the parents regarding occlusion therapy (patching) of the good eye to strengthen the weak eye
Corrective lenses may be indicated

Prepare for surgery. The surgery is performed to realign the weak muscles if non-surgical interventions are unsuccessful. It is performed usually before 2 years
