Red reflex
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 which may be from rubella or other maternal infections
- Retinoblastoma - shows leukocoria.
Newborns are regularly screened for retinoblastomas with an ophthalmoscope.
According to Bate's Guide to Physical Exams, retinal detachment would result in the absence of red reflex in the affected eye.
