The macula is the central section of the retina at the back of your eye. It provides the “fine detail” vision which allows you to work, read and watch TV with clarity. Macular Degeneration causes a loss of central vision, and is the leading cause of blindness in the western world.
We use Ocular Coherence Tomography (OCT)which gives a three-dimensional view of the macula, so that our optometrist can tell early if you are at risk of Macular Degeneration.
The earlier treatment is implemented, the better the chances of preserving your central sight
Glaucoma is a slowly progressive disease which causes irreversible damage to the nerve fibres in the retina. This damage affects your peripheral vision first. Left untreated, glaucoma will ultimately affect your central vision as well. As the loss of vision occurs gradually, it often goes unnoticed until it is well advanced.
There are a number of tests that can diagnose glaucoma. The most important of these tests is OCT which gives us the ability to measure the thickness of your retinal nerve fibres and compares this with normal values for your age. Early diagnosis means that treatment can be initiated to preserve your sight when minimal loss of vision has occurred.
Diabetes affects the blood vessels (arteries and veins) in our body. The back of the eye relies on the oxygen from blood for nourishment, so diabetes can have serious effects on vision. Haemorrhages and micro-aneurysms (tiny bulges of the walls of blood vessels) can be detected by full-colour scanning with our retinal imaging system.
Our OCT can detect swelling in the retina caused by blood plasma leaks which are not visible with retinal scanning or conventional ophthalmoscopy. Early detection of diabetes allows earlier treatment which will reduce the potentially blinding effects of diabetic retinopathy.
