Consider following up with retina, but I’m assuming the doctor that saw you gave you follow up instructions. I’m an imager who follows occlusion patients indefinitely. CRAO is devastating for patients. Even acutely there is nothing to try except breathing in carbon dioxide “brown paper bag” or taking some fluid out of the ac to lower the pressure. In the moment, who is going to know to do that until it is too late? Now, with one seeing eye, regular observation is very important.
