Is subconjunctival hemorrhage dangerous, and how is it treated?

The conjunctiva—commonly referred to as the eye conjunctiva—is a thin, transparent membrane covering the sclera and inner surface of the eyelids. Subconjunctival hemorrhage occurs when small blood vessels or capillaries beneath the conjunctiva rupture. Is subconjunctival hemorrhage dangerous, and how should it be treated?

Is subconjunctival hemorrhage dangerous, and how should it be treated?

Subconjunctival hemorrhage is generally low-risk and typically resolves spontaneously within one to two weeks. In most cases, it poses no serious threat to health. Treatment primarily involves two phases: hemostasis (stopping the bleeding) and promoting absorption of the blood. During the first 3–5 days after onset, cold compresses are recommended: wrap an ice pack in a clean towel and apply it gently to the closed eyelid for approximately 10 minutes, three times daily. This helps constrict blood vessels and halt further bleeding. Once bleeding has ceased, warm compresses may be applied—using a warm (not hot) damp towel—for about 10 minutes, three times daily—to enhance absorption of the extravasated blood.

Subconjunctival hemorrhage can sometimes be associated with underlying systemic conditions, the most common being hypertension. Its occurrence may serve as an early warning sign of elevated blood pressure. Therefore, individuals experiencing subconjunctival hemorrhage should undergo a comprehensive physical examination to assess for other potential complications—including fundoscopic evaluation to detect retinal hemorrhages or other signs of vascular damage—and to rule out systemic bleeding disorders. A full-body assessment is strongly advised.

If you feel anxious or alarmed by this condition, consult a physician for a simple, routine physical examination. However, such concern is usually unwarranted—most cases are benign and isolated, with no underlying pathology. We hope this article has been helpful to you!
