What are the Symptoms of Glaucoma?

With over 200,000 Australians living with glaucoma, it’s seen as one of Australia’s and the world’s leading causes of blindness and visual disability. Glaucoma is usually characterised by the buildup of pressure within the eye (known as intraocular pressure or IOP) that damages the optic nerve that links the eye to your brain. The extent of damage to the nerve can range from mild to severe, with extreme cases causing total blindness.
The types of Glaucoma
Open-angle: The most common type of Glaucoma, open-angle causes a gradual loss of vision, due to the eye’s filter mechanism becoming more resistant to the outflow of fluids. It’s generally found in older people as intraocular pressure builds up over time putting strain on the optic nerve.
Closed-angle: Closed-angle glaucoma causes more immediate and painful loss of vision due to unusual iris configuration blocking access to the eye filter.
Damage progresses very slowly and destroys vision gradually, starting with the side vision. One eye covers for the other, and the person remains unaware of any problem until a majority of nerve fibres have been damaged, and a large part of vision has been destroyed. This damage is irreversible.
It is progressive and usually relentless. Treatment cannot recover what has been lost. But it can arrest, or at least, slow down the damage process. That is why it is so important to detect the problem as early as possible, to be able to start treatment with as little damage to the vision as possible.
