High blood pressure may lead to loss of vision, say doctors
Blood leakage in the retina of people who have high blood pressure can lead to sudden loss of vision or permanent blindness, say doctors.
The condition is called retinal arterial macroaneurysm (RAM). It can lead to gradual loss of vision in the affected eye. This depends on which part of the retina has been affected by the leakage.
Doctors say that 75% of people with RAM have high blood pressure. 25% are elderly people.
There is no precaution that can be taken directly against RAM. However, if someone over the age of 60 years with high blood pressure suffers a sudden or steady loss of vision, a doctor should be consulted right away.
The initial treatment for the condition involves using laser beams to seal the leaking capillary in the retina.
The next part is invasive. It involves inserting a mixture of a gas and air to get rid of the layer of blood.
Once the fresh leakage of blood stops, the blood that remains in the jelly of the eye is flushed out by injecting a gas into the eye.
Studies say the disease affects one in 9,000 people across the world.
