I have begun to have another problem with my vision. As far as I realized it is random but so far occurs only at night. My left eye vision will turn to a red tint completely red. White fridge red and everything around it a darker reddish color. Sometimes its both eyes but mostly just my left eye. Is anyone else having the vision changes and has your doctor said it is related to the Chiari? I currently have blind spells from the Chiari but this color changing just started.
