What is Subconjunctival Hemorrhage?
The outermost protective coating of the eyeball is known as Conjunctiva. It is the thin, transparent and moist membrane covering the white portion of the eye(known as sclera) and the inside of the eyelids. Conjunctiva comprises many nerves and small blood vessels. These tiny blood vessels in conjunctiva are rarely visible but when inflamed, they get larger and more visible. Because the blood vessels are pretty fragile, their walls may easily break and result in the bleeding under the conjunctiva known as the Subconjunctival hemorrhage. It is also known as Subconjunctival haemorrhage, Hyposphagma etc. This condition in the eye would usually appear as a bright red or dark red patch on the sclera of the eye and can be noticed when properly seen in the mirror.
Though a subconjunctival hemorrhage may worry you when you notice for the first time, it must be informed that it is usually a harmless condition and would disappear in one or two weeks.
