A retinal detachment is an eye condition involving separation of the retina from its attachments to the underlying tissue within the eye. Most retinal detachments are a result of a retinal break, hole, or tear.
Retinal detachment occurs when the retina becomes separated from the nerve tissues and blood supply underneath it. While painless, visually this has a clouding effect that has been likened to a gray curtain moving across the field of vision.
Retinal detachment is a treatable condition, but it must be taken care of promptly, or it can cause vision loss and in the worst cases, blindness.
