What should I do if there is a red blood spot in my eye?

The appearance of a red blood clot in the eye typically refers to bleeding on the surface of the conjunctiva—commonly known as subconjunctival hemorrhage. This condition occurs when capillaries beneath the conjunctiva rupture due to various causes, leading to localized pinpoint or patchy hemorrhages as the affected area expands. So, what should you do if you notice a red blood clot in your eye? Below, we address this question.

What to Do If You Have a Red Blood Clot in Your Eye

1. Identify and Control Underlying Triggers

A red blood clot in the eye is usually caused by subconjunctival hemorrhage, often associated with increased capillary fragility. It commonly occurs in patients with hypertension, ocular trauma, or those who habitually stay up late or overuse their eyes due to fatigue. Management primarily focuses on controlling the underlying condition.

2. Physical Therapy

During the first 24 hours after onset, local cold compresses are recommended—apply a cool, damp towel gently over the closed eyelid to help prevent further expansion of the hemorrhage. After approximately 48 hours, switch to warm compresses, which promote local ocular blood circulation and aid absorption of the blood.

3. Pharmacological Treatment

It is advisable to avoid staying up late and engaging in strenuous physical activity. Topical antibiotic eye drops may be used to prevent secondary infection. Oral vitamin C supplementation—or other medications that facilitate hematoma absorption—may also be beneficial. In cases of extensive hemorrhage, oral blood-activating and stasis-resolving agents may be prescribed.

The above outlines key management strategies for subconjunctival hemorrhage. We hope this information is helpful to you.
