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 ...
A tear in the retina can allow fluids from the eye to leak in behind the retina, which causes retinal detachment. When this occurs, blood from the retinal blood vessels can bleed into the vitreous. [4] Retinal tear accounts for 11.4–44% of vitreous hemorrhage cases. [1]
In one study, optic nerve sheath hemorrhage was present in all 13 infants with non-accidental intracranial injury, and multilayered retinal hemorrhage was present in at least one eye of 11 of the 13 infants. [21] Hyphema is a complication that can occur after glaucoma filtering surgery, although the causes are not always well known.
Branch retinal vein occlusion revealed by laser Doppler imaging through flow alteration in the upper right branch artery. The diagnosis of branch retinal vein occlusion is made clinically by finding retinal hemorrhages in the distribution of an obstructed retinal vein. Fluorescein angiography is a helpful adjunct. Findings include delayed ...
Depending on the location and extent of the bleeding, valsalva retinopathy usually resolves within weeks to months, without any complications. [4] Patients are instructed to avoid anticoagulant drugs and physical activities which cause increase in intrathoracic or intra-abdominal pressure. [4]
Advanced retinopathy lesions, such as microaneurysms, blot hemorrhages and/or flame hemorrhages, ischemic changes (e.g. "cotton wool spots"), hard exudates and in severe cases swelling of the optic disc (optic disc edema), a ring of exudates around the retina called a "macular star" and visual acuity loss, typically due to macular involvement.
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Intraretinal microvascular abnormalities (IRMA) are abnormalities of the blood vessels that supply the retina of the eye, a sign of diabetic retinopathy. [1] IRMA can be difficult to distinguish from and is likely a precursor to retinal neovascularization. One way to distinguish IRMA from retinal neovascularization is to perform fluorescein ...
