"What Causes Sudden Red Blood Clots to Appear in the White Part of the Eye?"

Subconjunctival Hemorrhage

The sudden appearance of a red blood patch in the white part of the eye, medically known as subconjunctival hemorrhage, can be attributed to various factors such as excessive force or trauma, alcohol consumption or strenuous exercise, abnormal blood coagulation, conjunctivitis, hypertension, among others. If accompanied by other abnormal symptoms, immediate medical attention is advised.

1. Excessive Force or Trauma

Rubbing the eyes vigorously, severe coughing, vomiting, or minor ocular trauma (e.g., being hit by a ball) can rupture small blood vessels beneath the conjunctiva, leading to bleeding. No specific treatment is required as the blood will be absorbed within 1-2 weeks. In the initial 48 hours, apply cold compresses to constrict blood vessels and reduce bleeding; switch to warm compresses after 48 hours to facilitate blood absorption. Avoid rubbing the eyes vigorously and maintain ocular hygiene.

2. Alcohol Consumption or Strenuous Exercise

Vigorous vomiting after drinking or engaging in high-intensity exercise may temporarily elevate blood pressure, causing rupture of small blood vessels beneath the conjunctiva. Apart from the red blood patch, symptoms like dizziness and nausea may occur. Avoid strenuous exercise and limit alcohol intake. Manage bleeding as mentioned above, with cold compresses followed by warm compresses. Maintain a balanced diet rich in vitamin C and K to support vascular health.

3. Abnormal Blood Coagulation

Deficiency or dysfunction of coagulation factors can impair blood clotting, resulting in subconjunctival bleeding even from minor trauma. It may be accompanied by bleeding tendencies in other areas, like gum bleeding or skin bruises. Treatment should address the specific cause of coagulation abnormality under medical supervision, such as coagulation factor supplementation or anticoagulant medication.

4. Conjunctivitis

Caused by bacterial or viral infections, conjunctivitis can lead to conjunctival hyperemia, edema, and, in severe cases, rupture of small blood vessels. Prescribed antibiotic or antiviral eye drops, like Levofloxacin Eye Drops or Acyclovir Eye Drops, should be administered based on the pathogen type. Maintain ocular hygiene to prevent cross-infection.

5. Hypertension

High blood pressure in hypertensive patients can lead to the formation of microaneurysms in ocular small vessels, which may rupture and cause bleeding. Antihypertensive medication should be taken as prescribed. Manage ocular bleeding as mentioned earlier, while monitoring overall vascular health through regular health check-ups. If a red blood patch persists or is accompanied by other uncomfortable symptoms, seek prompt medical examination and follow doctor's instructions for treatment.
