What should I do if there is a sudden red blood spot on the white of my eye?

A sudden red blood spot on the white of the eye may be related to physiological factors, or could result from pathological causes such as eye trauma or epidemic hemorrhagic conjunctivitis. It is advisable to promptly identify the underlying cause and choose appropriate treatment under a doctor's guidance. Specific analyses are as follows:

I. Physiological Factors

Regularly staying up late, irregular sleep schedules, and prolonged eye strain can lead to rupture of small capillaries in the conjunctiva, causing subconjunctival hemorrhage. If there are no unusual symptoms, special treatment is usually unnecessary. However, maintaining good eye hygiene and avoiding eye fatigue is important to prevent worsening of the blood spot.

II. Pathological Factors

1. Eye Trauma

Injuries such as blunt trauma or foreign body penetration can easily affect capillaries, leading to rupture and bleeding, resulting in symptoms like eye pain and swelling. Mild cases may be managed with cold compresses. When necessary, consult a doctor about using medications such as erythromycin enteric-coated capsules, amoxicillin granules, or olopatadine hydrochloride eye drops.

2. Epidemic Hemorrhagic Conjunctivitis

Caused by viral infection, this condition leads to congestion and swelling of conjunctival blood vessels. Once rupture occurs, it results in blood spots within the eye, accompanied by pain and increased secretions. After onset, consult a doctor regarding use of medications such as tobramycin-dexamethasone eye drops, fluorometholone eye drops, or kanamycin sulfate eye drops. In severe cases, superficial keratectomy may be considered. Regular follow-up visits are recommended during recovery.

In addition, high blood pressure may also contribute. It is recommended to clearly identify the specific cause, actively cooperate with medical treatment, and maintain healthy eye habits.
