Hypertension and the Eyes – Silent Signs We Can Spot

High blood pressure doesn’t just affect your heart, it can also impact your eyes. The small, delicate blood vessels in the retina are especially vulnerable to changes in blood pressure. This means your eyes can sometimes show early signs of hypertension, even before you notice any other symptoms.
What Can High Blood Pressure Do to Your Eyes?
- Narrow or damaged retinal blood vessels
- Retinal swelling or fluid leakage
- Changes to the optic nerve from prolonged pressure
- Increased risk of stroke in the eye or blocked vessels
- Long-term risk of vision loss if left untreated
These changes are often subtle, but with a thorough eye exam, we can detect them, sometimes even before your doctor has picked them up.
How Can We Help?
At VISION Michael Hare Optometrists, we offer:
- Ultra-wide field retinal scans to capture detailed images of the retina
- OCT imaging (Optical Coherence Tomography), when indicated
- Careful assessment of retinal arteries and veins
- Reports and images shared with your GP if any changes are detected
Even if your blood pressure is well controlled, regular eye exams are crucial for monitoring the long-term effects of hypertension on your eyes.
If you have high blood pressure, or a family history of it, book an eye exam with VISION Michael Hare Optometrists. Your eyes might tell us more than you think.
