Pediatricians can screen for vision and/or life threatening eye diseases. The minimal "well baby" screening for newborns is done during the first three months of life should include the following exams:
- The Red Reflex: checks for a normal red reflection in the eye that occurs when light travels inside the eye, hits the retina and the blood tissue, and is reflected back.
- The Corneal Light Reflex: when a light is shined into each cornea a symmetrical beam of light is reflected back in the same spot on each eye. This helps to determine whether the eyes are crossed.
- An Eye Examination: to check for any structural abnormalities. From six to twelve months of age, the eyes' ability to fix and follow objects both individually and together is evaluated. Between the ages of three and five, the examination of the eyes is coupled with testing for visual acuity, color vision and depth perception.
Parents can observe the red reflex which can be seen by dimming the room lights and using a flashlight to shine light directly into the child's eyes.
