Glaucoma is a gradual loss of peripheral vision leading to tunnel-like vision and even blindness. It causes damage to the optic nerve where it leaves the eye to carry visual information to the brain. Glaucoma is the second most common cause of blindness. When left untreated, most types of Glaucoma progress towards a gradual worsening of irreversible, visual damage, often without any warning or symptoms. Up to 50% of affected people are not even aware they have it. There are actually several types of glaucoma but the vast majority of cases are termed ‘primary’ as they occur without a known cause. Some forms do occur at birth but it generally appears in people aged 40 and over and it frequency increases with age along with other risk factors such as racial ancestry, family history and high myopia. Although irreversible, early treatment or surgery can halt or slow down the disease and early detection is therefore essential. Regular eye exams with Smithdown Eyecare are recommended and a family history of glaucoma will entitle you to a free NHS test if you are over 40.
AGE-RELATED MACULAR DEGENERATION (AMD)
AMD is a painless eye condition that causes you to lose central vision, usually in both eyes Central vision is what you see when you focus straight ahead. In AMD, this vision becomes increasingly blurred, which means:reading becomes difficult, colours appear less vibrant & people's faces are difficult to recognise. This sight loss usually happens gradually over time, although it can sometimes be rapid. AMD doesn't affect your peripheral vision (side vision), which means it will not cause complete blindness.
Cataracts cause glare and haloes around lights, night driving problems, blurred, cloud, filmy or fuzzy vision. It is normal for the lens inside the eye to change with age. With most people, the lens gradually becomes less clear and not as much light is able to pass through. This is one of the reasons why people often need stronger light for reading as they become older. Because of this, more light is scattered within the eye which can result in greater sensitivity to bright light. The lens can even become cloudy, which is known as a cataract. Cataracts are mostly found in people over the age of 70. Hundreds of thousands of people undergo successful treatment each year for cataracts. Treatment is not always necessary and usually depends on how much the cataract is interfering with your vision.
