Leukocoria
Leukocoria (also white pupillary reflex ) is an abnormal white reflection from the retina of the eye.

Leukocoria is a medical sign for a number of conditions, including Coats disease , congenital cataract , corneal scarring , melanoma of the ciliary body , [ 2 ] Norrie disease , ocular toxocariasis , persistence of the tunica vasculosa lentis (PFV/PHPV), retinoblastoma , and retrolental fibroplasia

It can occur in animals that lack eyeshine due to the absence of a tapetum lucidum.

leukocoria can also occur in animals that lack eyeshine because their retina lacks a tapetum lucidum
-
In rare cases, it is caused by Coats' disease involving leaking retinal vessels.

In some rare cases (1%) the leukocoria is caused by Coats' disease (leaking retinal vessels).

Presents as an abnormal white reflection from the retina.

The red reflex test is used for screening, where a white reflection indicates leukocoria.

May appear in low indirect light, similar to eyeshine.

Leukocoria may appear also in low indirect light, similar to eyeshine.

Retinoblastoma, a potentially life-threatening cancer, is usually considered during evaluation.

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

Leukocoria (also white pupillary reflex) is an abnormal white reflection from the retina of the eye. Leukocoria resembles eyeshine, but leukocoria can also occur in animals that lack eyeshine because their retina lacks a tapetum lucidum.
Leukocoria is a medical sign for a number of conditions, including Coats disease, congenital cataract, corneal scarring, melanoma of the ciliary body,[2] Norrie disease, ocular toxocariasis, persistence of the tunica vasculosa lentis (PFV/PHPV), retinoblastoma, and retrolental fibroplasia.
Because of the potentially life-threatening nature of retinoblastoma, a cancer, that condition is usually considered in the evaluation of leukocoria. In some rare cases (1%) the leukocoria is caused by Coats' disease (leaking retinal vessels).
On photographs taken using a flash, instead of the familiar red-eye effect, leukocoria can cause a bright white reflection in an affected eye. Leukocoria may appear also in low indirect light, similar to eyeshine. [citation needed]
Leukocoria can be detected by a routine eye exam (see Ophthalmoscopy). For screening purposes, the red reflex test is used. In this test, when a light is shone briefly through the pupil, an orange red reflection is normal. A white reflection is leukocoria.[citation needed]
