My mother will be 94 in May, and she is feeling progressively weaker and confused. About a month or two ago she developed an eye infection, which she previously cured with eye drops. She has gone through two types of antibacterial drops and two weeks on an antiviral eye drop after seeing a specialist in an Urgent Care centre. It seemed to be starting to heal, but then took a turn for the worse. Is this another part of the end stages?
