Subconjunctival hemorrhage

Subconjunctival hemorrhage refers to bleeding caused by the rupture of small blood vessels beneath the conjunctiva. The blood tends to accumulate in a sheet-like fashion within the subconjunctival tissue, forming bright red or dark red patches under the conjunctiva. It commonly occurs in one eye. It can affect individuals of any age, but is more prevalent in older adults. It is usually asymptomatic, though occasionally there may be a sensation of eye fullness or foreign body sensation.
