A detached retina is a common eye disease. It can lead to blindness without good treatment. A detached retina is highly relevant to myopia. Myopia can change the internal structure of eyes. So it's easy to cause retinal off, especially high myopia. Besides, As time progresses, Vitreous and retinal of the eyes produce pull force, it can also cause the detached retina.
Retinal detachment is a pathological state of retinal neurepithelium layer and the human retinal pigment epithelium are separated from each other. The patients who have retinal detachment may have flash sense, floaters, visual field defect, central vision loss and other symptoms, it needs timely treatment. If you have timely surgery, macular detachment can be reset within 5 days, and the visual function can be recovery. But if retinal detachment is lasted for a long time, even the operation is successful, the visual function will have a permanent damage.
The detached retina is also called retinal detachment, which means the retina peels away or detaches from the underlying layer. At the beginning, the retina just detached for a small part. However, the whole retina would be detached if it doesn't treat in time. Usually, there are different types of detached retina, which are rhegmatogenous retinal detachment, exudative, serous or secondary retinal and tractional retinal detachment.
A detached retina is a serious and sight-threatening event, occurring when the retina becomes separated from its underlying supportive tissue. The retina cannot function when these layers are detached. And unless the retina is reattached soon, permanent vision loss may result. It also called Retina Detachment. Symptoms and Signs: spots, floaters and flashes of light are the warning signs of a detached retina. Your vision might become blurry, or you might have poor vision. Another sign is seeing a shadow or a curtain descending from the top of the eye or across from the side. No pain is associated with retinal detachment. If you experience any of the signs, consult your eye doctor right away. Immediate treatment increases your odds of regaining lost vision. An injury to the eye or face can cause a detached retina, as the eyes can be very high levels of nearsightedness. Extremely nearsighted people have longer eyeballs with thinner retinas that are more prone to detaching. LASIK surgery, cataract surgery, tumors, eye disease and systemic diseases such as diabetes and sickle cell disease also may cause retinal detachments.
The retina is a thin, light-sensitive, tissue which covers the inside back portion of the eye. In most situations, the retinal detachment is caused by the presence of one or more small holes or tears in the retina.When a retinal tear appears, watery fluid vitreous space may pass through the hole and flow between the retina and the back wall of the eye, which separates the retina from the back of the eye and cause s it to detach. The detached portion of the retina will not work proper, and there will be a blur or blind spot in the vision.
It is the detachment between neurosensory of retina and pigment epithelium. For people with heavy myopia it is a frequently-occurring disease. The early symptom is to see black shadow or floaters moving. Do not rub your eyes or take strenuous exercise. Neither should you use eye drops indiscriminately. Go and see the eye doctor if your eye sight declines. Because 7 days after detachment even surgery cannot help recover the eye sight.
