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.
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 ...
The most common cause found in adults is diabetic retinopathy. Abnormal blood vessels can form in the back of the eye of a person with diabetes. These new blood vessels are weaker and prone to breaking and causing hemorrhage. [2] Diabetic retinopathy accounts for 31.5–54% of all cases of vitreous hemorrhage in adults in the United States. [1]
[2] [3] Generally only one eye is affected. [2] Causes can include coughing, vomiting, heavy lifting, straining during acute constipation or the act of "bearing down" during childbirth, as these activities can increase the blood pressure in the vascular systems supplying the conjunctiva. Other causes include blunt or penetrating trauma to the eye.
Additional causes of spontaneous hyphema include: rubeosis iridis, myotonic dystrophy, leukemia, hemophilia, and von Willebrand disease. [3] Conditions or medications that cause thinning of the blood, such as aspirin, warfarin, or drinking alcohol may also cause hyphema. Source of bleeding in hyphema with blunt trauma to eye is circulus iridis ...
The most common treatments are medications and surgery to repair the damaged blood vessels in your brain. Valvular heart disease Heart valve problems may be treated with medications or surgery.
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.
"Lipid-rich plaques build up over time and can decrease blood flow through the blood vessel, or the plaque can rupture, causing a blood clot which shuts down the blood vessel and restricts blood ...
