Subconjunctival bleeding, also known as subconjunctival hemorrhage or subconjunctival haemorrhage, is bleeding from a small blood vessel over the whites of the eye. It results in a red spot in the white of the eye. [1] There is generally little to no pain and vision is not affected. [2] [3] Generally only one eye is affected. [2]
A subconjunctival hemorrhage can often occur without any obvious cause or harm to the eye. A strong enough sneeze or cough can cause a blood vessel in the eye to burst. Hyphema is a result of blunt or penetrating trauma to the orbit that increases intraocular pressure, causing tears in the vessels of the ciliary body and iris.
AHC can only exist in a human host and is transmitted through human contact with an infected individual or object, such as a towel used by an infected person. It is also easily communicable through fecal-oral pathways, thus allowing for its abundance in areas of the world with low levels of hygiene. Within one to two days of infection, symptoms ...
Conjunctivitis and subconjunctival hemorrhage are two of the less serious but more common causes. Management includes assessing whether emergency action (including referral) is needed, or whether treatment can be accomplished without additional resources.
Blebitis – if infectious can progress to devastating endophthalmitis; Suprachoroidal hemorrhage – rupture of long posterior ciliary artery from progressive stretching with progressive serous choroidal detachment; usually occurs several days after trabeculectomy with acute pain often while straining; Hypotony – wound revision [6]
[5] In pure orbital blowout fractures, the orbital rim (the most anterior bony margin of the orbit) is preserved, but with impure fractures, the orbital rim is also injured. With the trapdoor variant, there is a high frequency of extra-ocular muscle entrapment despite minimal signs of external trauma, a phenomenon that is referred to as a ...
Bleeding, hemorrhage, haemorrhage or blood loss is blood escaping from the circulatory system from damaged blood vessels. [1] Bleeding can occur internally , or externally either through a natural opening such as the mouth , nose , ear , urethra , vagina or anus , or through a puncture in the skin .
Mild conjunctivochalasis can be asymptomatic and in such cases does not require treatment. Lubricating eye drops may be tried but are often ineffective. [8] If discomfort persists after standard dry eye treatment and anti-inflammatory therapy, surgery may be undertaken to remove the conjunctival folds and restore a smooth tear film.
