Definitions for "LEUKOCORIA"
A whitening of the pupil of the eye.
White pupil (absent "red reflex") indicating something white inside the eye (e.g. cataract, retinoblastoma).
A condition characterized by the appearance of a whitish reflex or mass in or behind the pupil. Leukocoria is also referred to as a Cat's eye reflex, because its appearance is similar to that of a cat's eye. Lumbar Puncture(LP) If retinoblastoma has spread to the brain, the tumor cells may be floating in the cerebral spinal fluid (CSF) which bathes the brain and the spinal cord. A lumbar puncture can test for the presence of these tumor cells. To obtain a sample of the CSF for testing, a small amount of the fluid is drawn through a narrow needle at the base of the spine. Macula A small area at the back of the eye in the light sensitive layer (the retina) which allows us to see fine detail and colour. The closer a tumor a treatment scar is to the macula, the poorer the outcome for remaining vision.
