What is glaucoma?

Glaucoma is a group of eye diseases that damage your eye’s optic nerve (essential bundle of nerve cells that carries visual signals from the eye to the brain), causing progressive and irreversible loss of vision. Glaucoma is typically attributable to an accumulation of intraocular pressure, or pressure inside your eye. Such intraocular pressure can injure your optic nerve that transmits images to your brain. If the damage exacerbates, glaucoma can result in long term vision loss or total blindness and is important to know the glaucoma symptoms to prevent this from happening.

What are the two main types of glaucoma?

Open angle, or wide-angle glaucoma, is the most common type of glaucoma. The ‘angle’ refers to the drainage angle at the front of the eye which allows fluid to drain from the eye. In open angle glaucoma, fluid in the eye does not drain out like it should.

Angle closure glaucoma occurs when your eye does not drain fluid as expected, due to a narrow drainage space between your iris (coloured tissue in the eye) and cornea (transparent layer at the front of the eye surface). As a result, your eye pressure accumulates and causes damage to the optic nerve.

What are the symptoms of glaucoma?

The symptoms of glaucoma differ based on how advanced your condition is as well as the type of glaucoma you are suffering from.

Glaucoma can lead to blindness if treatment is neglected or ignored. Around 15% of people with glaucoma lose their vision in at least one eye within 20 years despite undergoing treatment.
