sickle cell retinopathy (blockage of blood vessels in the retina and choroid that results in abnormal blood vessel growth and thinning of the retina).This situation leads to inflammation and scar tissue membranes within the vitreous that can cause TRD. In response, the retina signals the growth of new, abnormal blood vessels that leak and bleed into the vitreous. When this happens to the retina, it leads to ischemia due to lack of oxygen. If you have diabetes, the various metabolic changes or imbalances in your body can lead to a variety of complications. Instead, formation of dense fibrous strands of inflamed vitreous bind to the retina, causing membrane contraction and pulling that result in your retina detaching. Tractional retinal detachment (TRD) - also called retinal traction detachment (RTD) - does not involve any breaks or tears in your retina. They are also more common in people who are nearsighted. Rhegmatogenous retinal detachments are often a result of natural aging but can also be caused by injuries or as the result of previous eye surgeries. Your retina can become detached partially or fully, and it may occur over the course of a few hours to a few months. This causes your retina to come loose and detach. Liquified vitreous fluid inside of your eye can then pass through this break and collect behind your retina. This type of retinal detachment happens to about 1 in 10,000 people.Ī rhegmatogenous retinal detachment occurs when you develop a break, small hole, or tear in your retina. The most common type of retinal detachment is called rhegmatogenous (pronounced reg-ma- todge-en-us). Let’s take a detailed look at each of the three types of retinal detachment.
