mum been to opticians today for an eye check, she has had two recent cataracht ops, so was for a check up for new glasses, the optician spent a long time on her eyes and then said she was referring her back as she could see what look like a birth mark at the back of her eye which wasn t there before, she said she was surprised the hospital hadn t picked it up when they did the catarach, any suggestions as to what this could be, she is light sensitive too at the moment.
