Doctors from the American Academy of Ophthalmology said that the reflection of the flash, which gives a bright red color to the eyeballs in the photo, is an indicator of healthy blood circulation in the retina. White pupils may be a symptom of a rare type of cancer called retinoblastoma. In this respect reports Daily Mail edition.
It is known that the “red eye effect” in flash photography is caused by the eye shining into the space where the blood vessels are located. Red pupils in this case indicate absolutely healthy eyes and normal blood flow to the retina.
Experts also noted that the absence of flash reflection in one eye could be a sign of strabismus, a condition in which both eyes do not look in the same direction. White pupils may indicate the development of a rare type of cancer called retinoblastoma.
Malignant eye tumors with retinoblastoma develop mainly in childhood from tissues of embryonic origin. In this case, the light color of the pupils in the photo is due to the reflection of light from the white cancer cells at the back of the eye. Ophthalmologists added that white pupils could also be a sign of retinal detachment or eye infection.
Sometimes pupils can appear yellow in flash photos. This may be a warning sign of Coats disease, a very rare, congenital, non-inherited eye disease that causes complete or partial blindness and is characterized by abnormal development of the blood vessels behind the retina.
former oncologist named obvious symptoms of eye cancer.
