Age Related Macular Degeneration
Age related macular degeneration (ARMD) is the most common cause of vision loss in those aged over 50. ARMD causes a gradual loss of central vision. We need central vision for detailed tasks such as reading and driving.
Glaucoma is the main cause of preventable blindness in New Zealand. It is usually associated with raised pressure within the eye but can occur in eyes with normal pressure. Glaucoma or 'the silent thief of sight' is a progressive eye condition that causes damage to the optic nerve resulting in permanent vision loss. Usually, by the time you recognise any changes in your vision, it is too late. Glaucoma that is caught early can often be treated and any further damage prevented.
Normally the lens of your eye is clear, as a cataract forms the lens clouds and can cause impairment of your vision. Most cataracts are related to ageing and is therefore more common in older people.
Often when the cataract begin to affect your vision and lifestyle, you may need cataract removal surgery, which in most cases, is a safe and effective procedure.
When you have been diagnosed with diabetes, especially type 2 diabetes, one of the most important things you should do is get your eyes checked. The delicate blood vessels and light sensitive cells of the retina at the back of the eye can be affected by changes caused by diabetes thus leading to a condition called diabetic retinopathy.
