This non-communicable disease, which is known to show no symptoms, hence its name 'the silent killer', ends up developing into highly serious blood pressure is when the force of blood pushing against the artery wall is too high. For this, the heart has to work harder to pump no treatment is given, hypertension can damage blood vessels throughout the body. Besides leading to health problems like heart disease, stroke and kidney disease, high blood pressure can also damage your vision.

'In India, about 22.6% of the population has hypertension. This puts a large part of the population at risk for severe vision problems. Thankfully, we now have advanced, non-invasive tools like OCTA and OCT EDI that help us detect early damage in the retina and optic nerve caused by hypertension.'advertisementHOW HIGH BLOOD PRESSURE AFFECTS YOUR EYESWhen high blood pressure damages the small and delicate blood vessels that carry blood to the eyes.
