if the anitbiotics havent made a difference,and he has an undeveloped eye.... maybe he has a sinus / tear duct problem?
has the vet checked all his face for deformities? (I imagine an x-ray or whatever would cost a fortune!)
has he tried antihistimines?
our little Alfie had a gungy eye when we had them, and gets very wet eyes when its windy, or even if I've just changed the litter-tray...I think its the dust when its poured in!
he's grown out of the worst of it, so there's hope for young Bert

?got a picture of them?
