I have been diagnosed with glucoma for over 14 years and have been taking two eye drops daily. One of the eye drop is called Xalamol and the other is Zalatan/lanatroprost. I started using Zalatan when the doctor discovered that 95% of my nerves on my left eye is damaged and over 80% damaged on my right eye. I started suffering from dizzy spells when I reverse the car and unexpectedly at other times. I need some advise on what to do. Is there alternative medicine available or things I can do to help my situation.
