Red reflex

From Wikipedia, the free encyclopedia

The red reflex refers to the reddish-orange reflection from the eye's retina that is observed when using an ophthalmoscope or retinoscope.

Many eye problems may be detected by this test, such as:

• Cataracts - show leukocoria, or white coloration of the eye
• Retinoblastoma - shows leukocoria.

Newborns are regularly screened for retinoblastomas with an ophthalmoscope.

According to Bates Guide to Physical Exams, retinal detachment and vitreous would cause the patient not to have a red reflex.
