Question: Does hypertension impair vision? Almudena (Santander).
Answer: Hypertensive retinopathy is the set of changes that take place in the retina in relation to high blood pressure. These changes can be seen on examination of the fundus thanks to an instrument called an ophthalmoscope, which allows the retina and its vessels to be viewed directly through the pupil. This device has a lens system that makes it possible to enlarge the image and a light source that illuminates the inside of the eye.
