Symptoms of a Subconjunctival HemorrhageThe sclera is the white part of your eye that is covered by a thin, clear tissue called the conjunctiva. The conjunctiva also lines the inside of your eyelid and houses a network of tiny blood vessels, called capillaries. Capillaries are fragile and can easily break. The burst vessel will then leak blood into the space between the conjunctiva and sclera. The main symptom of a subconjunctival hemorrhage is a blood-red discoloration on the white of the eye. Over time, the redness will then turn a greenish or yellowish color, much like a bruise. The symptoms will usually disappear within two weeks. A subconjunctival hemorrhage is usually painless, although some people may experience a scratchy sensation in the eye.
