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 ...
Intraocular hemorrhage is classified based on the location of the bleeding: Hyphema (in the anterior chamber); Suprachoroidal hemorrhage (SCH) is a rare complication of intraocular surgery in which blood from the ciliary arteries enters the space between the choroid and the sclera.
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]
In general, branch retinal vein occlusion has a good prognosis: after 1 year 50–60% of eyes have been reported to have a final visual acuity of 20/40 or better even without any treatment. With time the dramatic picture of an acute branch retinal vein occlusion becomes more subtle, hemorrhages fade so that the retina can look almost normal.
Retinal vein occlusion: Especially in older people or those with cardiovascular risk factors, retinal vein occlusion, which is a blockage in the retina's veins, causes retinal hemorrhage and visual loss that resembles the symptoms of Terson's syndrome.
Laser photocoagulation can help prevent the deterioration of some retinal disorders and reduce the risk of future vision loss, but it cannot restore vision once it has been lost. The procedure is safe and effective for treating indicated retinal disorders, such as tears and glaucoma. It is typically an outpatient procedure lasting 15 to 20 minutes.
Using a laser, an ophthalmologist burns the portions of the retina that are not supported by blood vessels, a technique known as laser photocoagulation. [1] By doing so, this tissue will no longer release molecules that stimulate blood vessel growth. If a retinal detachment occurs, laser therapy or surgery may be required to repair the retina ...
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 ...
