Subconjunctival Hemorrhage

A subconjunctival hemorrhage occurs when a blood vessel breaks just underneath conjunctiva. The conjunctiva can't absorb the blood very quickly, so the blood is trapped under this transparent surface. A subconjunctival hemorrhage may look painful and unappealing, but it's usually a harmless condition that disappears within 10 to 14 days. Subconjunctival hemorrhage often occurs without any obvious harm to your eye, or it may be the result of a strong sneeze or cough that caused a broken blood vessel. You don't need any specific treatment for a subconjunctival hemorrhage. 


  1. Do you know why in the second image the pupil looks fully blown? Could it be that head trauma caused the haemorrhage as well? Just interested, love your blog + tumblr! :)

  2. I don't "know" why the pupil is dilated, but sometimes eye medications can make an eye dilate. (And some meds are used for this purpose, as constricted pupils can be harmful for the eye long-term.)
