Losing some or all of your sight can be very distressing and have a big effect on your life. People tell us that they struggle with a range of emotions from shock, anger, sadness and frustration, to depression and grief. This is quite normal and understandably coping with these emotions can be very difficult.ust how much help you will need depends on how your vision has been affected, but whatever your sight loss, we can help. Action for Blind People is an expert national organisation, ensuring blind and partially sighted people receive practical support.
Your retina is a thin layer of tissue that lines the back of your eyeball. It turns light into signals to the brain, which interprets them as sight. When a vein in the retina becomes blocked, itâs called retinal vein occlusion. This can give you blurry vision or even sudden permanent blindness in that eye. It's similar to retinal artery occlusion, which is sometimes called an eye stroke. The damage happens when a blocked vein keeps blood from draining from the retina. That raises pressure inside your eye, which can cause bleeding, swelling, and fluid leaks. Retinal vein occlusion can harm your eye in minutes. Usually, a blood clot blocks the vein.
