4 months ago my husband went into respiratory failure then multi system failure after having flu-like symptoms for several weeks. he was on a mechanical ventilator for 4 weeks, he is now able to walk with a cane and one assist. His major complaint is dizziness and his "eyes jumping" as he describes it.He has seen an opthomologist who had eyeglasses made for him with a prism to correct his vision. his vision has gotten worse since last month. Where can I start to get help to improve this condition?
