                        I would get a second opinion.  My grandmother had a detached retna.  It was only slight but considered serious and had immediate surgery.  After surgery she was fine.  The doctor said left un-treated she could have lost her sight in that eye.  This was many years ago and she never had any problems after the surgery and recovery was done.  I hope this helps.  Good luck.
