Types of glaucoma
There are various types of glaucoma including:
Chronic glaucoma – this is the most common type of glaucoma and develops very slowly.
Acute glaucoma – this is rare and may develop rapidly with a sudden, painful build-up of pressure in the eye. Other symptoms may include blurred vision and haloes around lights.
What are the symptoms of glaucoma?
If you have chronic glaucoma, it can take a long time before you realise you have a problem with your eyesight. This is because chronic glaucoma is painless and usually damages the outer edge of the vision and works slowly inwards. Without regular checks you may not notice a problem until the glaucoma is near the centre of your vision.
Acute glaucoma is rare but usually painful often accompanied by blurred vision and haloes around lights. If you get these symptoms it is important to seek immediate assistance. Contact your optician, doctor or local Accident and Emergency department.
Even if the symptoms go away you should contact your optician as soon as possible as repeat episodes can cause damage to your eyesight.
