Glaucoma is a group of eye diseases causing optic nerve damage. The optic nerve carries images from the retina, which is the specialized light sensing tissue, to the brain so we can see. In glaucoma, eye pressure plays a role in damaging the delicate nerve fibers of the optic nerve. When a significant number of nerve fibers are damaged, blind spots develop in the field of vision. Once nerve damage and visual loss occur, it is permanent. Most people don’t notice these blind areas until much of the optic nerve damage has already occurred. If the entire nerve is destroyed, blindness results. Glaucoma is a leading cause of blindness in the world, especially in older people. Early detection and treatment by your ophthalmologist are the keys to preventing optic nerve damage and vision loss from glaucoma.- Kellogg Eye Center
The regular eye tests that could save your sight
HEALTH chiefs have urged Wigan folk to have their eyes tested more often to increase earlier detection of a debilitating eye condition.
More than 15,000 patients in the borough have been assessed for glaucoma by The Wrightington Wigan and Leigh (WWL) Eye Unit in the last decade.
And figures show around 7,500 people are currently attending clinics for it at the Healthcare Centre, Boston House, Wigan and Leigh Infirmary.
Yuen Lambert, Ophthalmology Manager at the WWL Eye Unit, said: “People often don’t realise their sight is being damaged because the first part of the eye to be affected is the outer field of vision, their peripheral vision.
“It is important for those with a family history of glaucoma or for people over 40 to have a regular eye health check up with an optometrist, as this could ultimately save their sight.”
National Glaucoma Awareness Week highlights the importance of regular eye checks and early detection, as glaucoma is one of the leading causes of avoidable blindness. The condition affects up to two in 100 people over the age of 40.
Glaucoma, which involves an increased pressure in the eyeball causing gradual sight loss, develops very slowly and most patients will be unaware they are affected until it is quite advanced………..
