The eye and vision

eye anatomyThe eye is the organ that allows us to see. The eyeball itself is a sphere spanning approximately 24 mm in diameter. It is suspended in the bony socket by muscles controlling its movements, and is partially cushioned by a thick layer of fatty tissue within the skull that protects it during movement.

For more information, see The Eye and Vision.


GlaucomaGlaucoma refers to a group of disorders affecting the eyes. These disorders are characterised by increased pressure within the eye that causes damage to the eye tissues and the optic nerve, which is the main nerve controlling vision.

For more information, see Glaucoma.
