Some individuals have weak areas in their retinas that may also increase their risk of having vitreous separation and retinal tears. If you have high myopia (extreme nearsightedness), then you are at an increased risk of a tear or detachment. Retinal tears may result from trauma and other diseases (although rare). Almost all retinal detachments arise from vitreous separation due to normal aging. Many people are interested in knowing what causes retinal tears and detachment. A detached retina is malnourished and unhealthy and eventually results in vision loss that could be permanent. Once there’s a retinal tear or hole, the eye’s fluid moves through this opening and collects under the retina, detaching it from the eye’s wall. The retina receives its oxygen and nutrition from a collection of blood vessels between itself and the wall of the eye. However, retinal tears can worsen into retinal detachment and vision loss. Retinal tears may lead to bleeding inside the eye, blurring vision, and creating floaters. You can develop a retinal tear as this gel pulls on the fragile retina and the process may also lead to retinal detachment. The larger back chamber of the eye is filled with a clear gel called the vitreous.Īs stated before, a normal part of aging may lead to the vitreous gel shrinking and separating from the retina. The retina is a light-sensitive layer of tissue that lines the eye’s interior and sends visual messages via the optic nerve to the brain. The Difference Between a Retinal Tear and Retinal Detachment During this process, the vitreous gel may pull at the retina, leading to tears and possible detachment.
