Three quarters of visual impairment and blindness is caused by just five conditions.

Age Related Macular Degeneration
Age-related macular degeneration (AMD) is a disease associated with aging that gradually destroys central vision. Central vision is needed for seeing objects clearly and for common everyday tasks. AMD advances so slowly that people fail to notice the gradual deterioration of their vision. In others, the disease progresses faster and may lead to a permanent loss of central vision. Early detection and treatment is essential and can reduce vision loss in some cases. Family history of this disease increases the risk of developing AMD.
Cataract is a clouding of the lens inside the eye. Poor vision results because the cloudiness interferes with light entering the eye. Most cataracts form as a result of ageing and long-term exposure to ultra violet light. Cataract surgery is one of the most commonly performed surgical procedures in Australia and has a high success rate.
Diabetic eye disease (also known as diabetic retinopathy) is a complication of diabetes that affects the small blood vessels of the retina. It remains one of the leading causes of vision loss, despite availability of effective treatment if the disease is detected in the early stages. With early detection 98% of vision loss from this disease can be prevented.
Glaucoma is a disease involving damage to the optic nerve and subsequent vision loss or blindness. The exact causes of glaucoma are not known. The condition is often associated with increased pressure inside the eye, but it can also occur in people with normal pressure.
Once any form of glaucoma has been diagnosed it can be managed with various treatment options which are determined by your ophthalmologist. A family history increases the risk of developing glaucoma.
Refractive error is a disorder, not a disease. A refractive error means that the shape of the eye does not bend light correctly, resulting in blurred vision. Light has to be refracted or bent by different parts of the eye in order to see clearly. Refractive error is simply corrected with spectacles.
