Tests and diagnosis
By Mayo Clinic staffYour doctor will diagnose lazy eye with a thorough eye exam. He or she will look for a wandering eye, as well as a difference in vision between the eyes or poor vision in both eyes. Depending on your child's age, tests may include the following:
- Newborns. Red reflex test to look for cataracts, using a lighted magnifying device (ophthalmoscope)
- Infants. Test for ability to fixate their gaze and follow a moving object, as well as check for strabismus
- Toddlers. Red reflex test, photo screening or remote autorefraction
- Preschoolers and older children. Testing using pictures or letters. Each eye is patched in turn to test the other
Your doctor may also check for inflammation, tumors and other inner eye problems.
