Suggest Remedy For Change In Vision In The Right Eye

I am 58 years old and wear glasses. The vision in my right eye became blurry after being treated for blepharitis. My doctor prescribed antibiotics and steroid eye drops, along with antibiotic drops. The blepharitis cleared up, however my vision went from 20/20 to 20/80 in my right eye. The next week it had gone to 20/100. My eye doctor did some very specialized tests and has no idea what caused it or if it will clear up. He did mention that I had the beginning of glaucoma but it was not severe enough to cause the change in vision. I am very concerned and would appreciate any ideas or advice I was given. Thank you.
