Small spots or floaters may also indicate blood vessel leaks and may clear up in days, weeks, or even months. Proliferative retinopathy can cause retinal detachment. An ophthalmologist should monitor you closely for three to six months. Trauma, especially to the head, and several diseases may cause Purtscher's retinopathy Hyperviscosity-related retinopathy as seen in disorders which cause paraproteinemia Many types of retinopathy are proliferative, most often resulting from neovascularization or blood vessel overgrowth. People who have diabetic retinopathy often don't notice changes in their vision in the disease's early stages. People with diabetes do have a higher risk of blindness than people without diabetes. The poorly nourished retina then sends out some type of chemical distress signal that causes new blood vessels to bud and grow proliferate on the retinal surface. The macula is a very small area at the canter of the retina. The new blood vessels may bleed into the clear, jellylike substance that fills the canter of your eye.
The.etina is the nerve layer that lines the back of your eye . This is because damage too much of the retina can occur before your vision is affected. Although retinopathy does not usually cause vision loss at this stage, the capillary walls may lose their ability to control the passage of substances between the blood and the retina. After treatment, the eye may be covered with a patch for days to weeks and may be red and sore. Finally, light passes through another fluid-filled chamber in the canter of the eye the vitreous and strikes the back of the eye, the retina.
