Just like any other stroke, eye strokes usually occur when the important nerves of the eyes are starved of nutrients or oxygen. The result of this ailment is that a temporary loss of vision is experienced that may cause permanent damage in some cases. This problem generally arises as a side effect of some bigger problem like clogging of arteries, heart disease, diabetes, etc. There are many different types of eye strokes that a person may suffer from that have been listed below:
Branch Retinal Artery Occlusion: This type of eye stroke can result in a person losing peripheral and sometimes central visualization. The medical cause is the dislocation of a plaque from the heart walls and making its way to the eye area. In this case, the factors responsible for this are evaluated by doctors and treatment is prescribed accordingly. Most of these types of eye strokes are directly related to heart diseases. Immediate treatment should be taken in order to avoid further complications that may result in permanent vision loss.
Branch Retinal Vein Occlusion: As the name suggests, this type of eye stroke occurs due to the development of a clot in the vein. The diseases associated with this are diabetes and high blood pressure. The widely prescribed treatments for this type of occlusion are laser therapy and the administration of Lucentis.
Central Retinal Artery Occlusion: This eye stroke differs from the above mentioned two in a significant way as there is absolutely no pain associated with its onset. However, this is the most disastrous as there is complete loss of vision. It occurs when the flow of oxygenated blood to the retina is blocked because of a clot in the arteries of the neck. The main methods of preferred treatments that have been shown to provide results are glaucoma medications, surgical procedures and intake of carbon dioxide gas under the supervision of a certified medical practitioner. The associated diseases that act as a contributing factor for this eye stroke include cardiovascular diseases and diabetes. Clogging of arteries and thickening of artery walls play an important role in this type of occlusion.
