A blood clot inside the eye, usually a block or sheet of bleeding under the conjunctiva, is a very common condition in ophthalmology, usually due to a rupture of the subconjunctival capillaries from various causes, which causes a sheet of bleeding. In this case, no special treatment is needed. Small amounts of hemorrhage can be absorbed on their own and slowly return to normal, while more hemorrhage requires appropriate intervention. In the early stage of bleeding, within 24h, local cold compresses can be given to avoid the expansion of bleeding and prevent re-bleeding, and after 2 days, it can be changed to local hot compresses, which can promote the blood circulation around the eyes, so that the bleeding can be absorbed faster, and normally the disease can return to normal in about 7-12 days.
