I haven't had to deal with glaucoma, but based on discussions I've had with owners of dogs with the problem it is better to simply remove the eyes right away rather than try to save them. Everyone I've discussed this with said they never realized how much pain their dogs were in until the eyes were removed and their attitudes improved markedly.The biggest concern going forward is pain. Often times the eye need to be removed.
I also have never heard of it in such a young puppy.
I did have a dog who went blind later in life (nearly 12 years of age) and she adpated remarkably well.
