High Blood Pressure can harm your vision in numerous ways. Your eyes contain numerous little blood vessels called capillaries. When subjected to the long-lasting impacts of hypertension (HBP or high blood pressure, as it is also called), the following conditions can develop:
– Blood vessel damage (retinopathy): A lack of blood circulation to the retina causes obscured vision or the complete loss of sight. People with diabetes mellitus and hypertension are at an even greater risk for developing this problem. Managing blood pressure is also the only method to treat hypertensive retinopathy.
– Fluid accumulation under the retina (choroidopathy): This accumulation of fluid under the retina, the light-sensitive layer of tissue at the rear of the eyeball, which is responsible for capturing the ‘image’ which is then sent to the brain via the optic nerve for ‘seeing’, results in distorted vision or, in many cases, scarring that impairs vision and may cause partial vision loss.
– Nerve damage (optic neuropathy): The result of obstructed blood flow that harms the optic nerve, it can kill nerve cells in your eyes, which might create short-lived or permanent vision loss.
Hypertension can result in stroke (When a blockage or bleed of the blood vessels either interrupts or reduces the supply of blood to the brain. When this happens, the brain does not receive enough oxygen or nutrients, and brain cells start to die, resulting in impairment of many body functions which these cells manage including loss of sensitivity or paralysis in one side of the body. Stroke is a cerebrovascular disease) which can also cause vision loss, when parts of the brain which send, receive or process optic signals may be harmed. In addition to threatening the anatomy of the eye, hypertension is also a cause of stroke, which can impair the optic nerve or damages the part of the brain in charge of processing images.
