My dog suddenly went blind one night. The next morning he was fine. Brought him to a vet ophthalmologist and he was diagnosed with a small cataract in one eye, lens instability in both eyes, and they suspected glaucoma. They suspected glaucoma because of his sudden blindness the night before. He has been on 3 drops a day since we brought him in to keep down the pressure in his eyes and for the proper amount of drainage in his eyes. Since the past 4 weeks when he got diagnosed, he has maybe had 4 episodes of going blind for 20-50 minutes each episode. Why is he temporarily going blind for short periods every now and then? Does he have a chance for surgery to correct his eyes?
