H44.2: Degenerative myopia

The eyeball is made up of many different parts. The vitreous body of the eye consists of a transparent, gel-like fluid. It is surrounded by a thin membrane and fills the entire rear area of the eye. This is how it gives the eye its shape.

The choroid is the middle layer in the eye sheath. It lies between the sclera and the retina. There are lots of blood vessels in this layer. The choroid supplies the retina below it with oxygen and nutrients.

You are short-sighted. Being short-sighted means distant objects are blurred or you have to strain your eyes a lot to see clearly. This can happen, for example, if the eyeball is too long or the lens of the eye focuses the light too much. Alteration to the shape of the eyeball as a result of severe myopia can then pull on the layers around the eye. This can lead to the layers around the eye changing. This can affect the retina and the choroid, for example. The layers around your eye have changed in this way.

A change to the eyeball means you may no longer be able to see properly.
