Retinal detachment affects approximately 1 in 10,000 people. It can happen spontaneously or as a result of a blow to the eye or head. It is more common amongst older people and those who are short-sighted.
The most common symptom associated with a retinal detachment is a loss of vision out of the corner of one eye, often described as a shadow or a black curtain spreading across the visual field. You may also experience flashing bright lights or dark spots (floaters) in your vision. There is no pain associated with a retinal detachment.
If you begin to experience these symptoms you should consult your optometrist or GP immediately.
