What causes sudden loss of sight?

Loss of sudden vision may occur for many reasons, and most causes of loss of sudden eyes are painless. These include strokes, brain tumors, brain injuries, retinal separation and wet macular degeneration. Clots and venous blockages in the eye can also contribute to the loss of sudden eyes. Occupation of retinal artery generally occurs when blocks of blood clots block one of the arteries supplying blood to the retina of the eye. If the occlusion of the retinal artery is not immediately treated, the vision may be permanently loss. Most doctors believe that emergency care is essential to prevent retinal damage. The retinal vein occlusion

is blocked by the central vein of the retina, which helps move deoxygenated blood back to the lungs and hearts. This type of occlusion usually has other causes than embolisms and only about one third of patients recove their normal vision with treatment.

Amaurosis Fugax is the condition of the eye most common in geriatric patients suffering from vascular disorders. Amaurosis Fugax causesthat small blood clots block blood vessels inside the eye. These clots often disintegrate themselves and restore vision. However, persons with this disorder are exposed to an increased risk of stroke and more serious eyeblown.

Retinal disconnection can cause sudden loss of vision, although often the loss of vision associated with the retinal department occurs slowly, for several days. Persons who experience the separation of retina related to trauma may experience a greater loss of vision.

strokes, tumors and other neurological conditions may cause a loss of sudden vision if they damage part of the brain responsible for interpreting visual signals. Loss of vision related to neurological disorders may not be complete. Patients can experience blind spots or may lose peripheral vision. Some patients experience loss of internal or external areas of vision in both eyes.

macular hole or degeneration of part of the retina of the ZODPVerified for central vision can cause sudden loss of sight. Doctors do not yet understand all causes of macular holes, but bleeding in the eye has been involved. Loss of vision associated with this condition is not generally complete, but it can create blind places in the center of the patient's vision. Both eyes can be influenced, although experts do not yet understand why.

Eye bleeding, whether or not they are associated with permanent damage to the structures of the eye, can cause sudden loss of vision. Some conditions, including retinal tears, macular degeneration or diabetes, may increase the risk of such bleeding.

corneal injuries can also cause sudden loss of sight. Such injuries are usually painful and most patients are cuddly to combine the loss of vision with corneal injury before looking for medical treatment.
