leukocoria
white pupillary reflex

The most common sign at presentation is leukocoria (abnormal white reflection of the retina).

On photographs taken using a flash, instead of the familiar red-eye effect leukocoria can cause a bright white reflection in an affected eye.

The most common and obvious medical sign of retinoblastoma is an abnormal appearance of the pupil, leukocoria.

A white reflection is leukocoria.

Retinoblastoma - shows leukocoria.

Because of the potential life threatening nature of retinoblastoma, a cancer, that condition is usually considered in the evaluation of leukocoria.

This disorder is characterized by severe retinal malformations, cataracts, leukocoria and atrophy of the iris.

The first visible finding is Leukocoria, a grayish-yellow pupillary reflex that originates from a mass of unorganized tissue behind the lens.

The most common symptoms of diktyoma are vision loss and pain, while the most common signs are leukocoria and presence of a mass in the iris or ciliary body.

However, in humans and animals two effects can occur that may resemble eyeshine: leukocoria (white shine, indicative of abnormalities including cataracts, cancers, and other problems) and red-eye effect.

Leukocoria resembles eyeshine, but leukocoria can occur in humans and other animals that lack eyeshine because their retina lacks a tapetum lucidum.

In a photograph of a child's face, red-eye in one eye but not the other may actually be leukocoria, which may be caused by the cancer retinoblastoma, and the child's eyes should be looked at by a doctor or an ophthalmologist.

Patients with Norrie disease may develop cataracts, leukocoria (a condition where the pupils appear white when light is shone on them), along with other developmental issues in the eye, such as shrinking of the globe and the wasting away of the iris.
