Introduction
High blood pressure affects blood vessels throughout the body, including the small blood vessels inside the retina.
Changes in these retinal blood vessels are known as hypertensive retinopathy.
Many patients may have no noticeable eye symptoms in the early stages, which is why regular eye examinations can be valuable for people with long-standing hypertension.
