i don't have an answer to any of your questions. i am not extremely close to the couple. i just recently got better aquainted with them when they asked me to drive them to doctor appointments. they are very private people so, i am not going to ask them these questions.
my questions were very simple. could an allergy cause his eye to be very red (crimson) on one side of the sclara (sp?). could not using his eye med. for glaucoma cause the redness. i honestly doubt there are a million reasons for this type of redness on just one eye and on a very specific location.
