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 vitreous body is surrounded by the vitreous membrane. The vitreous membrane fulfills different functions. It protects the eye, supplies the eye with nutrients and is important for seeing, for example.

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. The nerve cells in the retina also form the optic nerve that connects the eye to the brain.

Your eyeball has reduced in size or your optic nerve has become thinner. This may be due to other disorders or injuries to the eye, for example.

An eyeball that has become smaller or an optic nerve that has become thinner means you may no longer be able to see properly. It is also possible for the affected eye to be sore.
