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. Leukocoria, or white coloration of the eye, is a diseased state that can be caused by one of many factors, including cataracts. The eyes of newborns are checked for leukocoria to screen for retinoblastomas.
