Glaucoma is the name given to a group of related diseases where the optic nerve is being damaged. The nerve fibres progressively die taking away the peripheral or side vision first. Visual loss often goes undetected until it is quite advanced. Glaucoma is the number one cause of preventable blindness in New Zealand and other developed countries.
Glaucoma often has no symptoms, so regular eye exams are essential. Elevated eye pressure is an important risk factor for developing glaucoma. Treatment for glaucoma is determined by a variety of factors but aimed at lowering pressure to prevent further loss of vision.
