Why are babies born with no eyes?

The causes of anophthalmia and microphthalmia among most infants are unknown. Some babies have anophthalmia or microphthalmia because of a change in their genes or chromosomes. Anophthalmia and microphthalmia can also be caused by taking certain medicines, like isotretinoin (Accutane®) or thalidomide, during pregnancy.

Can you sleep without eyeballs?

You might be surprised to hear that some people sleep with their eyes open. And it’s more common that you’d expect. About 20\% of people do it, including babies.

What causes a child to be born with one eye missing?

A child may be born with one, or both eyes, missing from the eye socket. The rare disorder develops during pregnancy and can be associated with other birth defects. The condition may be caused by genetic mutations and abnormal chromosomes.

When does a child need surgery for one eye?
