With proper treatment, the prognosis is excellent. More than 90% of detached retinas can be reattached successfully. In some cases, more than one treatment is necessary.
Vision is most likely to return to near normal if the problem is treated less than seven days after the detachment begins. Some blurring of vision may remain in people who have detachments that involve the macula (central vision). This is why treatment is an emergency if the macula is still attached.
