Hi I'm hoping someone can give me some answers. I went to the opticians today regarding floaters in my right eye and had the solution to widen my pupil so they could have a proper look. Following this I was told my right eye looks healthy however the back of my left eye has what looks like a birthmark and I'm to be referred to the eye hospital. My first question is why was this not picked up at any of my previous eye tests, can they not see the back of the eye in a normal test? My last one was less than 2 years ago. Secondly, is it possible that a birthmark could be cancerous?
Thank you in advanced x
