Oh bugger Alan about leaking behind both eyes. But good that they are monitoring it. I had one injection but it was for the retinal vein occlusion. Too many years after mine had developed for it to help. It was exactly the same injection as for diabetes and can be very successful. I was petrified but it didn't actually hurt. I think they are monthly injections for several months and there is a lot of waiting around. I think it is called Lucentis but I could be wrong. The actual procedure doesn't take very long at all and involves a local anaesthetic injected in the eye followed by the main injection. My vision was weird in the injected eye for about 48 hours afterwards - black swirly patterns - but then went back to normal.
In the meantime if you notice any change in your vision/ability to read please go to eye casualty Asap as the fluid may have leaked quicker than expected. Please do not wait for your appointment because early treatment is important.
