Most subconjunctival hemorrhages are spontaneous without an obvious cause. Often, a person may discover a subconjunctival hemorrhage on awakening and looking in the mirror. Most spontaneous subconjunctival hemorrhages are first noticed by another person seeing a red spot on your eye . When small, delicate blood vessels break beneath the tissue covering the white of the
eye ( conjunctiva ), resulting eye redness may mean that you have a subconjunctival hemorrhage.

Causes Of Subconjunctival Hemorrhage
Although it is not always possible to identify the source of the problem, some potential causes of subconjunctival hemorrhage include:
12 Side Effects And Dangers Of Too Much Caffeine Intake
  • Eye trauma can cause a broken blood vessel
  •  Aspirin or blood thinners such as warfarin (one brand name is Coumadin)
  •  Straining/ vomiting or a Valsalva maneuver, increasing the pressure in the veins of the head, as in weight lifting or lying on an inversion table upside-down. 
  • Rarely, a blood clotting disorder or vitamin K deficiency (vitamin K aids the functioning of proteins necessary for blood clotting)
  • Eye surgery, including LASIK and cataract surgery.
  • Bleeding disorder (a medical disorder causing bleeding or inhibiting normal clotting)
  • Certain infections of the outside of the eye ( conjunctivitis ) where a virus or a bacteria weaken the walls of small blood vessels under the conjunctiva

Diagnosis
Your health care provider or eye care provider will take a concise history of the events prior to the subconjunctival hemorrhage and perform an examination. Your blood pressure may also be checked. If you’ve been evaluated by your primary health care provider initially, you may be referred to an eye care specialist. If trauma was the cause, a more thorough examination using a slit lamp (a special microscope for examining the eye) will usually be performed.

Treatments For Subconjunctival Hemorrhage 
Usually, no treatment is required. Your health care provider or eye care provider may prescribe artificial tears to ease any irritation that may be present.
If the injury is related to trauma, your health care provider or eye care provider may need to examine your eye to rule out the possibility of damage to other parts of the eye.


Unless otherwise directed by your health care provider, you should avoid the use of aspirin, ibuprofen , naproxyn, or other nonsteroidal anti-inflammatory medications as these can increased bleeding.
