What is High Blood Pressure (Hypertension)?

High blood pressure or hypertension is a medical condition, characterized by the long-term force of blood against the artery walls being consistently too high. Blood pressure is determined by the amount of blood your heart pumps and the resistance to blood flow in your arteries—the more blood your heart pumps, the narrower your arteries, and the higher your blood pressure.

Hypertension is often referred to as a silent killer because it typically doesn’t cause symptoms until it has reached a severe or life-threatening stage. However, over time, if left untreated. It can lead to serious health problems such as heart disease, stroke, kidney disease, and even vision loss. In this blog, we will explore how high blood pressure affect eyes.

Impact of High Blood Pressure on Eyes

High blood pressure damages the retinal blood vessels. The retina is the light-sensitive layer of tissue at the back of the eyes. Increased blood pressure doesn’t just affect the heart and blood vessels; it also poses significant risks to the delicate structures of the eye.

• Hypertensive Retinopathy: High blood pressure can damage the tiny blood vessels in the retina, the light-sensitive tissue at the back of the eye. This condition, known as hypertensive retinopathy, can lead to vision problems, including blurry vision, headaches, and even vision loss if left untreated.
• Optic Neuropathy: Uncontrolled hypertension can also result in optic nerve damage, a condition called hypertensive optic neuropathy. The optic nerve transmits visual information from the eye to the brain. Damage to this crucial structure can cause vision loss and even permanent blindness.
• Retinal fluid build-up: The leaked blood vessels can cause fluid to build up. Over time it can distort or impair vision.
• Increased Risk of Eye Diseases: High blood pressure is often associated with an increased risk of developing other eye conditions such as glaucoma and diabetic retinopathy. These conditions can further compromise vision and require specialized treatment from eye specialists.
