Glaucoma is an older age condition which comes on gradually resulting in irreversible damage to the optic nerve head which is the part of the eye which sends visual information to the brain. Glaucoma can result in permanent visual impairment in some patients.
The risk factors for glaucoma are
- Family history
- Increased intraocular pressure (but this is not always the case)
Other risk factors include being highly short-sighted, being long-sighted, experiencing migraine, Raynauds, sleep apnoea, using steroid medication long term, and certain medications.
