I am sorry to hear about Ronnie, I have no experience of this, but I did find a few references on the net and they also said that it is possible for the retinas to reattach and for sight to return, it all depends on how long it has been like that for and how quickly it is treated. It sounds like you got Ronnie treatment really quickly, so fingers crossed that everything goes back where it should.

My friend had a dog that went blind, and he did adjust incredibly quickly. All her other animals seemed to know and make allowances for him. Being blind hasn't ruined his quality of life.

Hopefully this is just a temporary situation for Ronnie and his sight will come back.
