Red blood clots on the white eye is a relatively common clinical symptom, most patients find it when they look in the mirror or by colleagues or family members, and there are no special symptoms. Some patients may feel a slight grinding pain and foreign body sensation at the location of the red blood clots, and these are often found unnoticed. The most common cause is subconjunctival hemorrhage. The white eye is often referred to as a bulbar conjunctiva with many tiny blood vessels, and once these vessels rupture, they will produce local hemorrhage, which has no symptoms at the beginning and will slowly expand in scope as time progresses, but will slowly become lighter in color. Subconjunctival hemorrhage does not require special treatment and is not harmful, but requires a slow recovery.
