is weakened by a hole or a tear. This allows fluids to seep underneath slowly weakening the attachment leading to detachment. When detached the retina cannot make a clear picture from incoming rays of light and vision becomes dim or blurred. This condition is more frequent in middle aged short sighted people. Only 1 in 10,000 are affected.

Symptoms include a shadow spreading across the eye, bright flashes and dark spots called floaters. None of these symptoms are painful. Although many people experience flashes and floaters if they seem to be getting worse a checkup is important since prompt treatment can minimise damage to the eye.

Early treatment includes laser or freezing treatment under local anesthetic. However, an operation is usually needed to repair the hole or put the retina back in place. In 75% of cases the retina can be repaired with a single operation that does not cause much pain although the eye will swollen and sore for a few days after treatment.
