Vision

[Guest]

My 72 yr old father is slowly losing his peripheral vision in both eyes. After seeing eye doctors and neurologists and finding nothing in CAT scans of the brain, the only thing suggested was for him to stop his vitamin supplements for the next three months to see if perhaps they were toxic to his system and causing the vison loss. Anyone know where else to turn? I feel that we're losing time and feel frustrated they haven't found an answer. - Kathleen
