Pupil - white spots
White spots in the pupil is a condition that causes the pupil of the eye to look white instead of black.
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 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 of Pupil - white spots
- Coats' disease - exudative retinopathy
- Congenital cataract (may be hereditary or may result from other conditions, including congenital rubella, galactosemia, retrolental fibroplasia)
- Persistent primary hyperplastic vitreous
- Toxocara canis (infection caused by a parasite)
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, make an appointment with your health care 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.
