The tissue layer is that the photosensitive layer of tissue that lines the within of the attention and sends visual messages through the second cranial nerve to the brain. once the tissue layer detaches, it's raised or force from its traditional position. If not promptly treated, detached retina will cause permanent vision loss. In some cases there could also be little square measureas of the tissue layer that are torn. These areas, known as retinal tears or retinal breaks will result in detached retina. Here square measure 3 differing types of retinal detachment:
• Rhegmatogenous [reg-ma-TAH-jenous]—A tear or break within the tissue layer permits fluid to induce below the tissue layer and separate it from the retinal pigment epithelial tissue (RPE), the pigmented cell layer that nourishes the tissue layer. These varieties of retinal detachments square measure the foremost common.
• Tractional—In this kind of detaent, connective tissue on the tissue layer's surface contracts and causes the retina to break away the RPE. this type of detachment is a smaller amount common.
• Exudative—Frequently caused by retinal diseases, as well as inflammatory disorders and injury/trauma to the attention. during this sort, fluid leaks into the world beneath the tissue layer, but there aren't any tears or breaks within the tissue layer
