Pupil - white spots

Definition

White spots in the pupil is a condition that causes the pupil of the eye to look white instead of black.

Alternative Names

Leukocoria

Considerations

The pupil of the human eye is normally black. In flash photographs the pupil may appear red. This is called the "red reflex" by health care providers and is normal.

Sometimes, the pupil of the eye may appear white, or the normal red reflex may appear to be white. This is not a normal condition, and you need to see an eye care provider right away.

There are many different causes of white pupil or white reflex. Other conditions also can mimic white pupil. If the cornea, which is normally clear, becomes cloudy, it may look similar to a white pupil. Although the causes of a cloudy or white cornea are different from those of a white pupil or white reflex, these problems also need medical attention right away.

Cataracts may also cause the pupil to appear white.

Causes

Causes of this condition may include:

Home Care

Most causes of white pupil will cause decreased vision. This may often occur before the pupil appears to be white.

Detecting a white pupil is especially important in infants. Babies are unable to communicate to others that their vision is decreased. It is also harder to measure an infant's vision during an eye exam.

If you see a white pupil, call your provider right away. Well-child exams routinely screen for a white pupil in children. A child that develops a white pupil or cloudy cornea needs immediate attention, preferably from an eye specialist.

It is important to get diagnosed early if the problem is caused by retinoblastoma since this disease can be fatal.

When to Contact a Medical Professional

Contact your provider if you notice any color changes in the pupil or cornea of the eye.

What to Expect at Your Office Visit

The provider will do a physical exam and ask about your symptoms and medical history.

The physical exam will include a detailed eye examination.

The following tests may be performed:

Other tests may that be done include a head CT or MRI scan.

Eye
The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.
