The red reflex refers to the reddish-orange reflection from the eye's retina that is observed when using an ophthalmoscope or retinoscope from approximately 30 cm / 1 foot. This examination usually done in a dimly lit or dark room.

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 would cause the patient not to have a red reflex.
