Glaucoma is an eye disease in which fluid pressure in the eye damages the optic nerve. It can lead to blindness. Over the years, many medicines have been developed to reduce the fluid pressure and help take away the fear of blindness.

FAQ
-
What is it?
Glaucoma is an eye disease in which the optic nerve becomes damaged, leading to a gradual loss of peripheral vision. If untreated, it can lead to blindness. Glaucoma is caused by fluid in the eye not draining properly, resulting in increased pressure in the eyeball. -
Who gets it?
In Europe, glaucoma affects about 2 per cent of people over 40 years old. This rises to 7 per cent in those over 80. Surveys suggest that 1.5 million people have the condition - of whom only half have been detected. Glaucoma is responsible for the blindness of 10 to 15 per cent of people in Europe. -
What can be done about it?
Medicines, usually eye drops or gel, have been developed that reduce the fluid pressure. Laser surgery to open the drainage channels, or create a new drainage channel in the top of the eyeball, can be performed, but may not be suitable for everyone. -
What does the future hold?
There are now more medicines and surgical options available than ever before. The healthcare need is for more screening so that more patients can benefit from available treatment. Recently, genes that may predispose someone to glaucoma have been discovered. This may pave the way for early genetic testing and diagnosis.
