Hot or cold compresses can be used for eye diseases, but there are principles for choosing hot or cold compresses, and not all diseases can be treated in the same way. In the case of ophthalmoplegia, cold compresses are usually given in the early stages when the pain is very obvious, and then local hot compresses are given when the pain is reduced. In the case of eye fatigue, local hot compresses are usually given to improve the blood circulation around the eyes and thus improve the symptoms of eye fatigue. In the case of allergic conjunctivitis, a cold compress should be applied to reduce the itchy eyes. For subconjunctival hemorrhage or subcutaneous hemorrhage caused by trauma, cold compresses should be given within 24 hours in the early stage of the injury and gradually changed to hot compresses after 48 hours. So. After the eye disease, do not blindly cold compress or hot compress, according to the different conditions to choose.
