retinal arteries การใช้

• In October 2013, Araki lost the vision in his right eye due to a retinal artery obstruction.
• Uchida successfully underwent emergency eye surgery on May 31, 2005 for a blocked retinal artery, which would have led to blindness.
• Fran鏾is and his collaborators did important research on the anatomy of the central retinal artery and the central optic nerve artery.
• The cherry red spot is seen in central retinal artery occlusion, appearing several hours after the blockage of the retinal artery occurs.
• The cherry red spot is seen in central retinal artery occlusion, appearing several hours after the blockage of the retinal artery occurs.
• Larvae are thought to enter the eye through the optic nerve, central retinal artery, short posterior ciliary arteries, soft tissues, or cerebrospinal fluid.
• The fovea and a small area surrounding it are not supplied by the central retinal artery or its branches, but instead by the choroid.
• In 2009, the Undersea and Hyperbaric Medical Society added " central retinal artery occlusion " to their list of approved indications for hyperbaric oxygen ( HBO ).
• However it should be remembered that the Cilio retinal artery itself is a branch of the Short Posterior Ciliary Arteries which is derived from the Ophthalmic Artery.
• Accidental intravascular injections are more difficult with blunt-tip microcannulas, reducing the risk of skin necrosis, ulcers, and embolization to the retinal artery which can result in blindness.
• Therefore, its possible for the cilio retinal artery itself to occlude causing significant visual loss in the perfused macula region ( surrounding visual field will remain intact ).
• Retinal artery occlusion ( such as central retinal artery occlusion or branch retinal artery occlusion ) leads to rapid death of retinal cells, thereby resulting in severe loss of vision.
• Retinal artery occlusion ( such as central retinal artery occlusion or branch retinal artery occlusion ) leads to rapid death of retinal cells, thereby resulting in severe loss of vision.
• Retinal artery occlusion ( such as central retinal artery occlusion or branch retinal artery occlusion ) leads to rapid death of retinal cells, thereby resulting in severe loss of vision.
• The cherry red spot is seen because the macula receives its blood supply from the choroid, supplied by the posterior ciliary arteries, while the surrounding retina is pale due to retinal artery infarction.
• The ophthalmic artery supplies the choroid via the short posterior ciliary arteries and the retina via the central retinal artery, however, the route to the choroid is typically less circuitous than the route to the retina.
• Women with the narrowest arteries and vessels in the retina _ the light-sensitive region at the back of the eye _ faced nearly double the risk of developing serious heart problems, compared with women with the widest retinal arteries.
• As the retinal blood pressure decreases below globe pressure ( usually 10 21 mm Hg ), blood flow begins to cease to the retina, first affecting perfusion farthest from the optic disc and retinal artery with progression towards central vision.
• Prevention of vision loss requires that certain conditions be met : the treatment be started before irreversible damage has occurred ( over 24 hours ), the occlusion must not also occur at the ophthalmic artery, and treatment must continue until the inner layers of the retina are again oxygenated by the retinal arteries.
• Previous research has linked narrowed retinal arteries with high blood pressure, but the study used specialized digital photographs and measurements to detect much less obvious narrowing than can be seen in standard eye exams, said Dr . A . Richey Sharrett, a co-author and researcher at the National Heart, Lung and Blood Institute.
