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 .
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.
Diagnosis can be further made under a slit lamp upon the observation of redundant conjunctival folds. These folds can be made more apparent by staining with fluorescein dye and by applying gentle upward pressure with a finger to the eyeball through the lower lid. In pure aqueous tear deficiency dry eye patients, fluorescein stains in the ...
Vitreous hemorrhage is the extravasation, or leakage, of blood into the areas in and around the vitreous humor of the eye. [1] The vitreous humor is the clear gel that fills the space between the lens and the retina of the eye.
Chemosis is the swelling (or edema) of the conjunctiva.The term derives from the Greek words cheme and -osis, cheme meaning cockleshell due to the swollen conjunctiva resembling it, and -osis meaning condition. [1]
Retinal hemorrhage (UK English: retinal haemorrhage) is a disorder of the eye in which bleeding occurs in the retina, the light sensitive tissue, located on the back wall of the eye. [1] There are photoreceptor cells in the retina called rods and cones , which transduce light energy into nerve signals that can be processed by the brain to form ...
Secondary hemorrhage, or rebleeding of the hyphema, is thought to worsen outcomes in terms of visual function and lead to complications such as glaucoma, corneal staining, optic atrophy, or vision loss. [1] Rebleeding occurs in 4–35% of hyphema cases and is a risk factor for glaucoma. [4]
