Sub Conjunctival Hemorrhage

A subconjunctival hemorrhage is a bleed underneath the conjunctiva- the transparent layer which lies over the white of the eye (the sclera). This bleeding is caused by the leaking of a blood vessel in the conjunctiva.

Causes

Subconjunctival hemorrhages are very common because the blood vessels in the conjunctiva are very fragile and can easily bleed a little. In most cases, there is no specific cause but the following are associated with the condition:

  • Strenuous activities
  • Coughing and sneezing
  • Vomiting
  • High blood pressure and taking blood-thinning medications such as aspirin or warfarin
  • Other potential causes include injury to the eye or rubbing the eye forcefully.
  • A subconjunctival hemorrhage can also happen following an eye operation.

Treatment

This condition usually does not require any treatment and will settle by itself within a week or two. If your eye is uncomfortable, lubricating eye drops may be recommended.

 

Signs and Symptoms

The hemorrhage usually appears suddenly as a red patch or spot on the white of the eye. It may be flat or occasionally slightly raised above the surface of the eye. It is usually painless and does not affect eyesight, though it can sometimes cause an ache or discomfort in the eye. Sometimes, it might go unnoticed until somebody draws attention to it.
