What causes bleeding behind the eye?
There are many reasons one might bleed behind the eye. First you might have Diabetic Retinopathy, which is a condition that interferes with the body's ability to use and store sugar. Over time, Diabetes may cause weakening of the small blood vessels found in the retina. These blood vessel changes are called Diabetic Retinopathy. Early stages of this cause Background Retinopathy,' causing small hemorrhages to form throughout the retina the more progressive this gets the more prone it is to bleed. sudden loss of vision. You can also have what is called a Vitreous Hemorrhage, this is blood within the back cavity of the eye. THe only symptoms of this are visual. The vitreous cavity has no nerves and, therefore, cannot sense pain, and pressure, etc. The visual symptoms experienced by patients with vitreous hemmorhage vary from mild to severe. YOu might have floating black dots, ( like pepper grains), a red or dark strand, or cloud floating or stationary within the field of vision. A more severe hemmorhage might produce symptoms such as a large dark curtain blocking part of the vision or even whole vision. There are many causes of Vitreous Hemmorhage, The blood almost always originates from the vessels in the retina. Bleeding can occur as a complication of the vitreous gel peeling free away from the retina, a process called Posterior Vitreous Detachment. Sometimes bleeding originates from the abnormal new blood vessels growing on the retina ( because of poor circulation)This occurs as a complication of Diabetic Retinopathy and other disorders that reduce the circulation in the retina. Less common causes include, bleeding from an aneurysm, or macular degeneration.
