What is a white reflection?

When a flash photograph is taken of a human being, the light will reflect off their eyes in such a way as to cause "red eye". In a child with an eye tumor, light will reflect like that of a cat. This "white reflection" is known as "white reflection". It can be a sign of several serious health conditions in children and is usually first diagnosed through photos.

In photos without red-eye, the light from the camera's flash will usually show up as a small white dot. This is because there is a small area at the back of the human eye where there are no cones or veins to absorb light. In contrast, cats have a membrane at the back of their eyes called the tapetum lucidum, which reflects light as white. If an eye tumor is present in a human eye, it will reflect all of the flash and create the glowing eye effect usually only seen in photos of cats.

Since white reflex is usually first diagnosed from photographs, it is important for parents of young children to take a monthly low-light photo with a flash. Since the size and shape of the tumor may cause the white reflection not to be seen from all angles, it is important that photos of the baby's face be taken from many different positions. The white reflex can appear in one eye or in both eyes.

Another way to ensure that the white reflex is diagnosed early is simply to have regular visits to the ophthalmologist. At these visits, the optometrist will shine a small light into your child's eyes. This will have the same effect on the eye as a photographer's flash and will help diagnose if everything is normal.

It is important for a parent to take their child to the doctor upon finding an instance of white reflection in photos taken of them. It can be a sign of many different conditions, from approaching blindness to eye cancer. Diagnosing a child for eye problems can be difficult, as young children and infants are often startled by doctor visits and have trouble sitting still. Sedation may be needed so the eye can be examined. Later, surgery may be needed to fix the eye problem.

White reflection can also appear in photos of adults. It is not usually a sign of cancer, but can be the result of cataracts. Adults should also see an optometrist as soon as possible to have their eye problem diagnosed.
