Hello! My 56 year old mother in law suffered from a central retinal artery occlusion a year and a half ago after she took a plane ride from California to Italy. The doctors can't quite figure out why it happened as she really doesn't have any pre-existing conditions of than varicose vains and slightly elevated cholesterol. She is now working out a lot which has been improving her cholesterol and general health.
My question is if anyone knows how safe it would be for her to fly again to come see us in Italy a year and a half later. Is there any medication she can take for the flight that would lower her risks if there are any?
She really misses us but is scared of the devastating effects another blood clot could cause.
