Diabetes is the fastest growing chronic condition in Australia. 956,000 Australians have Type 2 diabetes while 120,000 Australians have Type 1 diabetes. One in four people with diabetes have diabetic retinopathy (damage to the retina from diabetes).
Elevated blood sugar levels cause damage to the micro-circulation, and the eye is unique as it is the only place in the body it is possible to directly view this damage.
Retinal vein and artery occlusions
Retinal vein occlusions
A central retinal vein occlusion (CRVO) occurs when there is an obstruction of the outflow of blood from the eye back to the systemic circulation.
Retinal artery occlusions
A retinal artery occlusion can occur due to a blockage of the main artery supplying blood to the eye, known as a central retinal artery occlusion (CRAO).
Laser Refractive Surgery
Refractive laser vision surgery involves the use of an advanced laser system to reshape the focusing power of the cornea at the front of your eye. It is designed to reduce your need for glasses and contact lenses.
The two most common forms of laser vision correction surgery are LASIK and PRK. The following diagrams illustrate an eye that has emmetropia (no refractive error), myopia (short sightedness) and hyperopia (long sightedness).
