Glaucoma is caused by increased pressure inside the eye. It is caused by fluid inside the eye not being able to drain effectively. It can be due to genetic or congenital abnormalities or secondary blockage of the drainage angle through severe inflammatory cells, excessive blood, lens luxations or tumours. This increased pressure can cause blindness and pain. Once an eye has developed glaucoma, there is no cure. Our treatment instead aims to keep the eye comfortable and sighted as long as possible.
