Visual Changes
A visual change is any disturbance to the vision that is not indicative of normal health condition and function. HBP can damage the tiny, delicate blood vessels that supply blood to the eyes, causing damage to the retina. Damage to the light-sensitive tissue at the retina can lead to bleeding in the eye, blurred vision, and complete loss of vision.
There is even a greater risk if the human body is also struggling with diabetes in addition to HBP. Fluid buildup under the retina, can result in distorted vision or sometimes scarring that impairs vision and Nerve damage. Blocked flow can damage the optic nerve, leading to bleeding within your eye or vision loss.
The retina is the layer of tissue at the back part of the eye. It changes light and images that enter the eye into nerve signals that are sent to the brain. The higher the pressure and the longer it has been high, the more severe the damage is likely to be to the vision.
There is a higher risk of damage and vision loss when high blood pressure exists together with diabetes, high cholesterol level, or a body exposed to smoking.
Rarely, very high blood pressure develops suddenly. However, when it does, it can cause severe changes in the eye. Other problems with the retina are also more likely, such as:
- Damage to the nerves in the eye due to poor flow.
- Blockage of the arteries that supply to the retina.
- Blockage of the veins that carry from the retina.
