Diagnosis

Your doctor will conduct a thorough eye exam, checking for eye health, a wandering eye, a difference in vision between the eyes or poor vision in both eyes. Eyedrops are generally used to dilate the eyes. The eyedrops cause blurred vision that lasts for several hours or a day.

The method used to test vision depends on your child's age and stage of development:

  • Preverbal children. A lighted magnifying device can be used to detect cataracts. Other tests can assess an infant or toddler's ability to fixate his or her gaze and to follow a moving object.
  • Children ages 3 and older. Tests using pictures or letters can assess the child's vision. Each eye is patched in turn to test the other.
