Introduction

Background

Subconjunctival hemorrhage is defined as blood between the conjunctiva and the sclera, and it is involved in the differential diagnosis of a red eye.

Pathophysiology

Subconjunctival hemorrhage results from bleeding of the conjunctival or episcleral blood vessels into the subconjunctival space. The hemorrhage can be traumatic, spontaneous, or related to systemic illness.

Frequency

United States

Subconjunctival hemorrhage occurs frequently. Exact figures are unknown because it is a self-limited disorder.

Mortality/Morbidity

Subconjunctival hemorrhage is a self-limited condition when not associated with systemic illness.

Race

No racial preference for subconjunctival hemorrhage is evident.

Sex

No gender difference for subconjunctival hemorrhage is evident.

Age

Subconjunctival hemorrhage can occur at all ages, but it is more common with increasing age.

Clinical

History

  • Red eye
  • May have mild irritation
  • Usually asymptomatic

Physical

  • The most common appearance of a subconjunctival hemorrhage is a bright red patch with relatively normal surroundings. 
  • A slit lamp examination shows its precise location under the conjunctiva.
  • The view of the sclera may be obscured by blood. If thick, it may be dark red.

Causes

  • Idiopathic
  • Valsalva (eg, coughing, straining)
  • Traumatic (isolated or associated with retrobulbar hemorrhage or ruptured globe)
  • Hypertension/arteriosclerosis
  • Bleeding disorders (if recurrent or in young patients without history of trauma or infection), including hematologic or hepatic disease, diabetes, systemic lupus erythematosus, parasites, and vitamin C deficiency
  • Various antibiotics, drugs/chemicals (eg, coumadin, nonsteroidal anti-inflammatory drugs [NSAIDs], aspirin), steroids, contraceptives, and vitamins A and D have been associated with subconjunctival hemorrhage.
  • Normal sequelae of ocular surgery even if no conjunctival incision
  • Several febrile systemic infections can cause subconjunctival hemorrhage, including meningococcal septicemia, scarlet fever, typhoid fever, cholera, rickettsia, malaria, and viruses (eg, influenza, smallpox, measles, yellow fever, sandfly fever).
  • Subconjunctival hemorrhage has been reported as a result of emboli from long bone fractures, chest compression, cardiac angiography, open-heart surgery, and other remote operations.
