If the eye is scratched by a nail and there is significant white blood congestion or pain, it is best to go to the hospital for an examination, as most of this condition may be due to compensatory congestion of the conjunctiva formed by injury to the cornea. If the injury to the cornea is relatively superficial, it may only injure the epithelium and the symptoms will not be very serious. If the stroma is injured, it may cause significant pain, tearing and photophobia. If the problem is indeed at the epithelial level after a doctor’s examination, anti-inflammatory drops, such as levofloxacin, or a nutritive corneal ointment, such as calf blood deprotein eye extract, may be used to promote healing of the corneal epithelium. If the stroma is damaged, the medication is administered in the same way as before, with levofloxacin and calf blood gel being used together. Regular review is also required, and often scar healing is possible. If the location is in the pupil area, it may affect vision, if not in the pupil area, the impact on vision is also relatively small, but still need to be regularly reviewed to prevent infection can.
