Rare diseases of the eye list

Whether or not you believe the eyes are the window to the soul, there’s no doubt that peering into pupils can help doctors detect health problems.

Some are serious and rare and can only be detected when your doctor shines a light into your eyes or an optometrist or ophthalmologist dilates your pupils to look for nerve and blood vessel damage. Children benefit significantly from eye exams and pre-school eye screenings.

Below are five rare eye diseases that lurk deep inside the eyes. Read on to learn how they can affect vision and overall health.

Coats’ disease is a rare eye disease that can lead to blindness in one eye. It’s caused by an abnormal development of the blood vessels of the retina. Symptoms depend on the size and extent of the affected blood vessels, and typically begin between 6 and 8 years of age.

The disease may initially cause some vision loss or the eyes to appear crossed. A white mass also can develop in the pupil behind the lens.

As Coats’ disease progresses, individuals may develop glaucoma, cataracts or a reddish discoloration in the iris. The affected eyeball may also shrink and the middle layer of the eye may swell or become irritated.

It’s unknown what causes Coats’, but researchers suspect a genetic link. Treatment options are dictated by the stage of the disease when diagnosed. Often, doctors focus on closing the vessels that are leaking and salvaging as much vision as possible. However, advanced cases may require surgery.

Retinoblastoma is a life-threatening cancer that forms in the retina. It causes the pupil to appear white instead of red when light shines into it. This can be seen on a flash photograph. Other symptoms include eyes that appear to be looking in different directions, and pain or redness in the eye.

Retinoblastoma usually affects children younger than 5, and may affect one or both eyes. It can spread to other areas around the eye, brain or other parts of the body.
