I ve had glaucoma for 25-plus years and have had several surgeries. I ve lost part of the vision in my right eye and now my left eye s pressure is too low. It causes foggy vision and double lines of print. Any suggestions for treatment of low eye pressure? P.S. I ve tried many medicines for high eye pressure (glaucoma) over the years and I m currently using Zioptan in my right eye only. This med. was chosen due to the lack of preservatives (I m very sensitive). I ve also had several sinus surgeries and most of the honey comb material in the sinuses is removed. Help, please. Yes, I am seeing a specialist who is concerned about doing anything to raise the pressure in my low-pressure eye. My eye sight is getting worse. Any ideas?
