The retina is a thin layer of tissue that lines the back wall of the eye. It is responsible for absorbing light and converting it into a signal sent to the brain. A retinal detachment is serious eye condition which involves separation of the retina from its attachments to the underlying tissues.
Your retina is the light-sensitive layer of tissue that lines the inside of your eye. It sends visual messages through the optic nerve to the brain. When the retina detaches, it is lifted from its normal position. This can lead to retinal detachment, if not treated, causing even permanent loss of vision.
