The spread of blood to the black eye refers to conjunctival congestion, which usually does not lead to blindness.
The spreading of red blood to the black eye refers to the dilation of conjunctival blood vessels, which generally does not affect the patient’s normal vision, and may be caused by long hours of late-night work or the presence of a foreign body in the eye, and other factors. If the patient has no other symptoms, the possibility of blindness is very small.
Patients usually need to avoid rubbing their eyes with their hands, avoid looking at electronic products for a long time, and consume light, high-quality protein and vitamin-rich foods in their diet. If the eye infection is caused by bacterial infection, patients can follow the doctor’s instructions to use anti-infective eye drops treatment, such as tobramycin eye drops, levofloxacin eye drops and so on.
Patients with significant conjunctival congestion are advised to seek timely medical attention to assess their condition and follow medical advice.
