If bruising occurs after a blow to the eye area, it is generally recommended that local cold compresses be considered within 48 hours to promote vasoconstriction, prevent aggravation of subcutaneous bleeding and avoid re-bleeding, while local hot compresses and massage are applied after 48 hours to promote blood circulation and speed up the absorption of bruising.
Recovery may be possible after 1 week for less bleeding, but longer if the injury is more severe and bleeding is more frequent.
It is important to note that if, in addition to the stasis of blood, there are problems such as loss of vision and blurring, you should seek immediate attention from a hospital ophthalmologist to avoid serious consequences.
