I am not sure how you would stand on your insurance and changing policy providers, others on here who will probably know. All I can say is when you look at Dylan it is like he has a grey cover over his eyes. He has to have checks on his eyes every three months to make sure the pressure in his eyes is not too high. I do think you ought to get a referral from your vet to see an eye specialist. We went to the Royal Vet College at Cambridge. Saw a chap there he was super and great with Dylan, who also liked all the attention from the students. In some cases it is operable, but unfortunately Dylan has problems with his retina so was not a candidate for the op.
