A detached retina occurs when the retina is pulled or falls away from its normal position. The retina is a light-sensitive layer of tissue that lines the back of the eye. It converts visual images into nerve impulses in the brain that allow us to see.
Retinal detachment is painless. However, if it is not treated quickly, a detached retina can cause permanent, partial, or total vision loss. If you have any of these symptoms, contact an eye doctor right away:
Sudden appearance or increase in the number of floaters, which are shapes that float in the eye and are seen in the field of vision
Brief flashes of light in the eye
Loss of the eye’s central or peripheral field of vision
A curtain appears to fall over part of the visual field
