Thank you Penny your story made me smile, I must say that I have already decided to have the op on his "good" eye done asap, I can't see the point in waiting for what seems like the inevitable. What did you do with the blind eye? the ophthalmologist who was wonderful has said that if pressure doesn't stay down then he would recommend surgery to remove the eye. My thoughts are that his blind eye is only cosmetic so why would we leave in it! I really don't doubt that he can lead just as happy a life blind.
Thank you all for the support, I am coping very well with the news however my OH isn't and seems to think that extra treats are needed 
she had both eyes removed - the 1st was 3 weeks after she was diagnosed and the 2nd was 8 months later - both done, as leaving them were too painful to keep in to be honest (as I said she masked a lot too and once she'd recovered from the op she was visibly happier so I knew then she'd been in some pain all that time but hadn't always shown it) as when the pressure is raised it increases the pain levels, which is exacerbated with sunlight as the pupil can't react the same way a normal pupil will and is fixed open usually. I did nothing cosmetic re her eyes as some vets may suggest certain things but my eye vet is of the view that allowing their eye sockets to sink and leave it at that and let the fur grow over it a bit.
The op looks far worse than it is - am usually a toughie re the pets' ops but it made me cry when I saw her straight after her 2nd eye op (I had to carry her to the vets as that morning she was in so much pain and disoriented as she could hardly see so was upset by it all and the meds just weren't taking the pressure down any more). They recover in about 2 weeks as long as you ensure they have good antibiotic cover (and don't mind sometimes when they shake their heads blood comes spraying from their nose)
Once they no longer have any sight, because its more sudden than you'd get with old age I bought a pack of cat bells from pets at home (
http://www.petsathome.com/shop/en/pets/chrome-cat-collar-bells) they were louder/better than some you get and more robust - then I tied one to my left boot with either string or small cable ties and got her to follow the sound - they find it difficult at 1st being able to walk partly out of lack of confidence but once they understand where the bell is they're happier with it all. Certain things she was fine with I had to socialise her with again, such as being at the train station (I don't have a car so often go by train) - bless her as she was never one who enjoyed being carried but now knew I needed to help her with certain stuff (very few things though) so she'd get into a position where she knew I was about to pick her up to get on the train. She was so inspiring but then you have to let them bump around and not feel sorry for them.
The only thing I ever kept in the same place was the water bowl in the house. Even the leads were never in same place each day yet she began to seek them out and pick one up to bring me for a walk - made me well up with pride that day she 1st did it
Don't let anyone tell you your dog will have a limited life once blind - they need the encouragement to lead as normal life as possible - Roobs only went onlead in group walks as she got worried she couldn't find me very well and then when we went by the canal (she usually fell in even though she was happy diving into the river Taff) but as I said apart from that she did everything else (she learnt the 'watch' command as I was always prattling on when she was walking, particularly on pavements and I'd be saying 'now watch that curb', 'watch that post' and then I realised she slowed on the word 'watch' as she knew an obstacle was about and then she learnt the word 'round' that I used after it which meant she slowed down/stopped then went round a post).
