noun. an emergency situation in which a thin layer of tissue (the retina) at the back of the eye pulls away from its normal position
Retinal detachment separates the retinal cells from the layer of blood vessels that provides oxygen and nourishment. The longer retinal detachment goes untreated, the greater your risk of permanent vision loss in the affected eye.
Retinal detachment itself is painless. Warning signs of retinal detachment may include one or all of the following:
The sudden appearance of many floaters — tiny specks that seem to drift through your field of vision
Flashes of light in one or both eyes (photopsia)
Gradually reduced side (peripheral) vision
A curtain-like shadow over your visual field
