I was diagnosed the end of November and my first check also came back as background. I went back to the optician and he showed me the picture and where it was. I was also referred to the hospital as my normal eye check picked up high pressure. At 42 I am gutted but I have really got good control on a low carb diet and do not eat anything that pushes me over 7.
I would go and ask about the details, if it is a bleed it can disappear next time. I have an anurysm and that will not go.
My GP suggested I have had my symptoms years, looking back I have felt tired and unwell for years so maybe I have. I now feel the best I have for years so I am sticking to my diet. I have also lost 33lb and back in size 10 which is amazing apart from I can not stop shopping and the bank is looking sorry for it's self.
