What Your Eyes Reveal

DIABETES:
- Your optometrist may identify subtle changes in your eyes caused by unstable
blood sugar levels. With severe untreated diabetes, there's the risk of diabetic
retinopathy. The blood vessels inside the retina, become damaged and this can
lead to permanent blindness. A healthy retina is needed for good vision.

HEART DISEASE AND STROKE RISK:
- High blood pressure affects 3 in 10 adults, and many don't even know they have
it. It's a major risk factor for heart attack and stroke. Looking directly at the blood
vessels in your eyes an optometrist can identify haemorrhages and leaking vessels,
as well as changes such as hardening of the arteries.

BRAIN TUMOUR:
- An eye test can show a bulging optic nerve caused by increased pressure inside the
skull - one symptoms of a brain tumour.
