Glaucoma Week runs this month from March 11-17 so at Envision Optical this month we are concentrating our eye health awareness message on the very common eye sight threatening disease glaucoma. Our Optometrists are experts in vision and eye care, and the detection of eye diseases.
WHAT IS GLAUCOMA?
Glaucoma is a disease where the optic nerve at the back of the eye, which connects the eye to the brain, is progressively decaying. It is most commonly associated with raised fluid pressure inside the eye. The progressive decay of the optic nerve causes a gradual loss of peripheral vision, and if left untreated, the patient will eventually have severe irreversible vision loss and blindness, and a form of tunnel vision.

WHAT CAUSES GLAUCOMA?
There are a number of different forms of glaucoma with individual unique causative factors. Many are related to structural changes within the eye that impede the outflow of the internal aqueous fluid leading to increased eye pressure. Glaucoma genes have been identified in recent studies, and there has been shown to be a 10 times greater risk if you have a direct relative with the condition. Patients with diabetes, cardiovascular disease and myopia are also more likely to be affected.
