Retinal hemorrhage refers to bleeding within the light-sensitive tissue on the posterior wall of the eye. A retinal hemorrhage may be caused by diseases (e.g., hypertension, retinal vein occlusion, diabetes), use of certain medications (e.g., anticoagulant therapy), or a head injury.
Preexisting eye problems like retinal detachment or retinal vein occlusion (a blood clot in the retina's vein) can also lead to vitreous hemorrhage. With some Intraretinal hemorrhage was present in 34% of newborns and varied from a single dot hemorrhage in one eye to bilateral widespread hemorrhages, occasionally A vitreous hemorrhage can cause dramatic loss of vision as it physically may block light from hitting the retina. It is not an emergency despite the significant loss of Aug 30, 2010 Togioka states “[a]lthough the presence of RH [retinal hemorrhage] does not confirm the diagnosis of SBS.

The mean time interval to progression after disc hemorrhage was observed was 16.8 +/- 2.0 months for visual field changes and 23.8 +/- 2.9 months for optic nerve head changes. In eyes with disc hemorrhage, 27 (22%) of 121 had recurrent hemorrhages at a mean interval of 21.5 +/- 2.9 months after previous hemorrhage. Retinal hemorrhage may occur because of: Systemic hypertension Hypertension. Blunt or penetrating ocular trauma leading to traumatic hemorrhage. Chorioretinal inflammation (posterior uveitis, eg secondary to infectious, immune-mediated or neoplastic causes).

Distinguishing the type, number, and pattern of retinal hemorrhages may be helpful in establishing a differential diagnosis. Identification of ocular abnormalities requires a full retinal examination by an ophthalmologist using indirect ophthalmoscopy through a Se hela listan på mayoclinic.org Maternal and fetal factors other than vacuum-assisted delivery are significant correlates of moderate to severe retinal hemorrhage. Vacuum-assisted delivery among small for gestational age infants is closely correlated with moderate to severe retinal hemorrhage.

There are 2 types of retinal hemangiomas, based on clinical and histological characteristics: cavernous hemangioma 1,2 and capillary hemangioma. 3 Basically, a cavernous hemangioma is composed of clumps of dark intraretinal aneurysms and has a cluster-of-grapes aspect, while a capillary hemangioma is composed of tortuous, large-diameter capillaries lined by normal endothelium separated by polygonal interstitial stromal cells and usually have a “light bulb” appearance. 2
Your retina is the thin layer that lines the back of your eye. What causes retinal hemorrhage? Medical conditions, such as diabetes, high blood pressure, anemia, or leukemia WHAT IS A RETINAL HEMORRHAGE? Vitreous hemorrhage is bleeding into the vitreous humor, the clear gel that fills the space between the retina and the lens of the eye. This condition may result directly from retinal tears or neovascularization of the retina, or it may be related to bleeding from preexisting blood vessels in these structures. 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.
