Detached retina guide causes, symptoms and treatment options static electricity examples


The retina is the light-sensitive layer at the back of the eye that converts light images into nerve electricity out in one room impulses that are relayed to the brain to produce sight. When the retina separates from the deeper layers of the eyeball that normally support and nourish it, the retina is said to be detached. Without this nourishment and support, the retina does not function properly, and this can cause a variety of visual symptoms. For example, if the retina detaches near the macula, the part of the eye that is responsible for the center of the visual field (reading for instance), then there may be a sudden, significant blurring or loss of vision. However, if the area of detachment is closer to the outer edges of the retina, then the visual loss may be more like a curtain being drawn over one side of the visual field (the curtain effect). Other symptoms of retinal detachment may include floating shapes in the field of vision or brief flashes of light.

Although there are several types of retinal detachment, the most common one starts when a tear or hole develops in the retina, and some of the gel-like substance that fills the inside of the eye (vitreous fluid) leaks through the opening. Eventually, the leaking vitreous fluid gets types of electricity behind the retina, separating the retina from other layers of the eye.

The retinal tear that triggers a retinal detachment sometimes is caused by trauma. More often, it is caused by a change in the gel-like consistency of the vitreous fluid that can occur as a part of aging. This age-related change can occur unpredictably in older people, and there is no way to prevent it. Once this type of retinal detachment develops and causes symptoms, it can progress to total 10 gases and their uses blindness if it is not repaired promptly.

People who have had cataract surgery — Up to 3% of people who have had cataract surgery eventually develop a detached retina, making retinal detachment the most serious post-surgical complication of cataract treatments. The high rate of retinal detachments after cataract surgery may be related to the vitreous fluid inside the eye becoming watery instead of gel-like after surgery. If there has been a complication at the time of cataract surgery especially if the posterior capsule of the human lens has torn and there has been loss of the vitreous, jelly retinal complications especially detachment is even more common.

In many cases, the more risk factors a person has, the higher the risk of retinal detachment. For example, a very nearsighted person who also undergoes cataract surgery probably will have a higher risk of retinal detachment than someone who has cataract surgery and is not nearsighted. Overall, the risk of retinal detachment increases the older you get, and men are about 50% more likely to develop the problem than women.

After reviewing your symptoms, your doctor will ask about your medical history, especially any history of cataract surgery, nearsightedness, and diabetes or eye trauma. Next, your doctor will examine your eye, and will test how well you can see and your peripheral vision electricity prices per kwh 2013 (side vision). Finally, the doctor will use special eye drops to dilate (open) your pupils so he or she can examine the inside of your eye, including the retina. During this retinal examination, the doctor will check for retinal tears and areas of detachment by using a special hand-held ophthalmoscope (a lighted instrument for looking inside the eye) or a slit lamp. If necessary, your doctor will do more tests to determine the extent of your visual field loss.

To prevent retinal detachments that are caused by diabetic retinopathy, people with diabetes should try to maintain near-normal blood sugar levels and to avoid wide swings between high and low blood sugar levels. Also, all diabetics should have a thorough eye examination through dilated pupils at least once a year. If any retinopathy is detected the examinations should be done every six months. Treatment

If you have a detached retina, you gas laws worksheet with answers should be treated by an ophthalmologist, a physician who specializes in eye problems. Several techniques are available to repair retinal tears and to eliminate the area of separation behind the detached retina. Some options include (in some cases more than one of the options listed below may be combined):

Scleral buckling — First, a tiny hole is made in the sclera (the tough layer beneath the retina, also known as the white of the eye). Through this tiny hole, any vitreous fluid that has leaked behind the retina is drained, allowing the detached retina to fall back into its normal position. Next, a small tuck or indentation electricity 101 youtube is made in the sclera and secured with a silicone buckle.

Once treatment is complete, you will need to return to your ophthalmologist for regular follow-up visits. These visits are necessary to check for signs that the retina has detached again in your treated eye or if the problem is happening in your untreated eye. People who already have had a retinal detachment in one eye have an increased risk of detachment in the other eye. When To Call a Professional
