All A to Z Topics


Glaucoma is a term that describes a group of eye conditions that affect vision. There are four main types and chronic open-angle glaucoma is the most common.
Symptoms of glaucoma
The symptoms of glaucoma vary between the four main types. These are chronic open-angle, acute angle-closure, secondary and developmental glaucoma.
Causes of glaucoma
Glaucoma is caused by a blockage in part of the eye. This prevents fluid draining out of the eye, and increases pressure in the eye (intraocular pressure).
Diagnosing glaucoma
If you have glaucoma, it can take a long time before you realise that you have a problem with your eyesight. It is important to have regular eye tests.
Treating glaucoma
The aim of treatment for every type of glaucoma is to reduce the pressure in the affected eye, called the intraocular pressure.
Complications with glaucoma
Loss of vision is the main complication of glaucoma. This is why early diagnosis and treatment is so important.
