![]() So if the retinal detachment is causing a shadow in the side vision, that will not get better after laser demarcation. The first is that it doesn't really fix the detached retina, it just barriers off the detached retina. There are two main disadvantages to laser demarcation. It does not involve any incision or injection or surgery on the eye. The advantage of laser for retinal detachment is that the laser is very low risk. If there is a small retinal detachment and it is minimally affecting vision, treating it with laser can prevent it from growing into a larger retinal detachment. Some retinal detachments are very small and minimally affect the vision. One way to treat a retinal detachment is to demarcate it with laser. Retinectomy for proliferative vitreoretinopathy.Membrane peel for proliferative vitreoretinopathy.There are several approaches to a retinal detachment which include the following possibilities (some of which can be combined depending on the situation). If not promptly treated, retinal detachment can cause permanent vision loss. If the retinal detachment involves the center of the retina, central vision declines and sometimes becomes distorted. This is usually accompanied by a shadow in the side vision. When the retina detaches, it is lifted or pulled from its normal position. Once there is a tear, fluid can travel from inside the eye to under the retina. The vitreous inside the eye (see image) can pull on the retina and cause a tear. The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain.
