Subconjunctival Hemorrhage : Symptoms And Prevention Tips


A subconjunctival hemorrhage is blood from a broken blood vessel that is one of the tiny blood vessels located between the conjunctiva and the underlying sclera. The conjunctiva is the clear tissue that covers the white of the eye (the sclera) and lines the inside of both eyelids.


A subconjunctival hemorrhage usually is benign, causing no vision problems or significant eye discomfort despite its conspicuous appearance. But eye redness also can be a sign of other types of potentially serious eye conditions. Particularly if you have eye discharge , you should visit your eye doctor for an eye exam to rule out an infection caused by bacteria, viruses or other microorganisms.

The conjunctiva can't absorb blood very quickly, so the blood gets trapped. You may not even realize you have a subconjunctival hemorrhage until you look in the mirror and notice the white part of your eye is bright red.
The conjunctiva contains nerves and many small blood vessels. These blood vessels are usually barely visible but become larger and more visible if the eye is inflamed. These blood vessels are somewhat fragile, and their walls may break easily, resulting in a
subconjunctival hemorrhage (bleeding under the conjunctiva). A subconjunctival hemorrhage appears as a bright red or dark red patch on the sclera.

Symptoms Of Subconjunctival Hemorrhage 
Most of the time, no symptoms are associated with a subconjunctival hemorrhage other than seeing blood over the white part of the eye, most symptoms are -

  • The hemorrhage itself is an obvious, sharply outlined bright red area overlying the sclera. The entire white part of the eye may occasionally be covered by blood.
  •  The hemorrhage will appear larger within the first 24 hours after its onset and then will slowly decrease in size and may look yellowish as the blood is absorbed.
  •  Very rarely people experience pain when the hemorrhage begins. When the bleeding first occurs, you may experience a sense of fullness in the eye or under the lid. As the hemorrhage resolves, some people may experience very mild irritation of the eye or merely a sense of awareness of the eye.


Risk Factors 
Risk factors for a subconjunctival hemorrhage include:
. Diabetes
. High blood pressure (hypertension)
. Certain blood-thinning medications, such as warfarin (Coumadin, Jantoven) and aspirin
. Blood-clotting disorders

If the bleeding in your eye has a clearly identifiable cause, such as a bleeding disorder or blood-thinning medication, ask your doctor if you can take any steps to reduce the risk of a subconjunctival hemorrhage. If you need to rub your eyes, rub your eyes gently. Rubbing your eyes too hard can cause minor trauma to your eyes, which may lead to a subconjunctival hemorrhage.

Lubricant artificial tears can soothe the eyes, although eye drops cannot help repair the broken blood vessels. Make sure not to rub your eye, which can increase the risk of re-bleeding right after onset similar to how a nose bleed is susceptible to re-bleeding in the early stages.
