Hi i am a 42 year old male i take 2000mg metamorfin and 1 sitiglapten daily, i have just been for my third hospital eye test . This time the result was they had detected some change due to diabetes but there was no immediate threat to my eye site and gave me another appointment in a years time and said if i was worried to speak to my doctor which i have not done yet, can anyone tell me once the damage has started theres probably no stopping it and i will loose some or all my sight in years to come and to live with it and get used to the fact which i have heard , can someone PLEASE tell me the truth THANKS
