Diabetic retinopathy is the most common diabetic eye disease and a frequent cause of blindness in adults. It is caused by changes in the retina\u2019s blood vessels. However, blindness caused by diabetes is preventable with proper control of diabetes and with yearly eye examinations.<\/p>

Diabetes causes a problem with the blood vessels in the body. The blood vessels begin to leak fluid, blood and protein. In the eye, this leakage is seen in the retina as retinal bleeding and swelling. This blood and swelling interferes with the normal function of the eye, resulting in decreased vision. If this condition is not corrected, visual loss can be permanent. This type of retinopathy is called background, or non-proliferative, retinopathy.<\/p>

If treatment is not given, then the visual loss can progress until it begins to involve the central and reading vision. It is at this point that a victim of glaucoma may begin to notice trouble with their vision. If treatment is still not given, the vision in the eye can be lost. Visual loss from glaucoma is irreversible. Because vision loss from glaucoma can never be restored, it is critical to detect glaucoma before significant damage has occurred to the nerve. Proper treatment for glaucoma can be prevent further loss of vision.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

\"\"High pressure inside the eye is known to cause glaucoma. The normal eye continuously produces and drains fluid internally in order to maintain the normal shape and pressure of the eye. This normal shape and pressure is necessary for you to see properly. In glaucoma, there may be a blockage of fluid drainage or an excess of fluid production, which leads to high pressure inside the eye. If you have high eye pressure, the increased pressure may damage your optic nerve. Some people, however, are able to tolerate high eye pressure without developing glaucoma. The reason for this is unknown.\n\nSome people develop glaucoma even without evidence of increased pressure inside the eye. In fact, recent studies show that up to 50% of people with glaucoma may not have high eye pressure measurements. For example, people of Japanese descent are more prone to have glaucoma without elevated eye pressure.\n\nMany studies are in progress to discover the reason for glaucoma damage in people who do not have increased eye pressure. The two leading theories are that damage to the nerve is caused by poor circulation to the nerve or that abnormally high concentrations of naturally occurring chemicals or hormones cause the damage.\n\nScientists who believe that poor circulation causes glaucoma have used special ultrasound testing to show decreased blood flow to the eyes of some people with glaucoma. Many of these people with \u201cnormal pressure\u201d glaucoma also have other problems with their circulation, such as heart disease, poor circulation to their legs and feet, or hardening of the arteries.\n\nOther scientists have shown increased concentrations of glutamate and other chemicals in the eyes of people with glaucoma. These chemicals are naturally produced by the body, and in normal amounts, help with normal eye functions. In abnormally high concentration, however, these naturally-occurring chemicals can actually harm the very nerve tissues from which they are produced. Scientists still have not discovered why the body produces abnormally high amounts of these chemicals in eyes with glaucoma.\n\nDoctors and scientists are working to discover treatments to poor circulation to the optic nerve and treatments to decrease the concentration of these harmful hormones in the eye. Studies are under way to determine if improving circulation or decreasing the hormone concentration will help stop damage from glaucoma.<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Glaucoma can strike people of any age, sex, and race. Certain individuals, however, are at increased risk. Those at increased risk include persons of African descent, those with a family history of glaucoma, and possibly those with nearsightedness or high blood pressure. The risk of glaucoma also increases as one gets older. The risk of glaucoma increases markedly in people of African descent over the age of 35 years, and in people of Caucasian descent over the age of 50 years. Other risk factors for glaucoma include diabetes and a history of trauma to the eye.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

When the ophthalmologist examines your eye, he or she can detect glaucoma damage by the appearance of your optic nerve. A normal healthy nerve has a small cup-shaped hole in the center. As damage from glaucoma progresses, this hole in the center of the nerve enlarges, and replaces the healthy tissue of the nerve. Your eye doctor can detect progression of the disease by periodically examining the appearance of the nerve. Your doctor may also take photographs of the nerve in order to document the appearance at a specific point in time. This allows better comparison in the future to be certain that the disease has been stabilized.<\/p>

These photographs, called disc photos, are particularly helpful if your doctor believes that you are a \u201cglaucoma suspect\u201d. A glaucoma suspect is a person whose optic nerve appearance is suspicious for glaucoma, but does not demonstrate definite glaucoma damage. If you are a glaucoma suspect, your doctor will want to examine your optic nerve two or three times a year, and compare to the baseline disc photos to detect definite glaucoma damage as soon as it occurs. This will allow your doctor to begin treatment before the glaucoma has a significant effect on your vision.<\/p>

Another way to measure the amount of damage to the nerve is to measure the amount of peripheral or side vision that has been lost. Glaucoma does not affect your central reading vision until the late stages of the disease. At this late stage, vision may already be deteriorated to the point of partial blindness. Therefore, it is important to measure the peripheral vision in the early stages of the disease, so that proper treatment can be given to prevent blindness. This is accomplished with visual field testing, which is an examination that measures the amount of vision lost.<\/p>

To test the visual field, your doctor uses an instrument that flashes lights of various intensities. You place your head against a head rest and stare at a target light directly in front of the eye being tested. The machine then flashes lights in your peripheral vision. Some of these lights are bright and easy to see. Others are so dim that they are impossible to see even if you have no visual damage. Most lights are somewhere in between. When you see the light, you press a button and the machine registers your response. The machine then prints out a map showing any areas that you cannot see properly. Your eye doctor can repeat this measurement periodically to determine if the glaucoma treatment has been effective in stabilizing the damage.<\/p>

There are other types of specialized testing that have recently become available, such as measurement of the thickness of the nerve with a technique called scanning laser polarimetry (GD Nerve Fiber Analyzer), and short wavelength perimetry, which uses colored lights to test the visual field (peripheral vision). Both of these technologies are particularly helpful if a person is suspected of having glaucoma, but there is no definite damage visible (glaucoma suspect).<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

The most common type of glaucoma is open angle glaucoma. Open angle means that there is no visible obstruction to the drainage area inside the eye. It is thought that there may be an invisible obstruction to fluid drainage in the trabecular meshwork, which is the structure in the eye that drains the fluid.<\/p>

Another type of glaucoma is narrow angle glaucoma. In this condition, an obstruction to the drainage area inside the eye occurs. This type of glaucoma is most common in persons of Chinese descent and Vietnamese descent, and less common in persons of African and Caucasian descent. However, it can affect a person of any race. This type of glaucoma may cause symptoms of sudden pain, redness, blurred vision, and colored haloes around lights. This condition is called acute narrow angle glaucoma, and must be treated immediately. Failure to treat this condition immediately can cause permanent loss of vision. Sometimes narrow angle glaucoma is a chronic condition that does not cause any symptoms, like open angle glaucoma. Your doctor can determine if you are at risk of narrow angle glaucoma by performing a procedure called gonioscopy.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

There are several ways to treat this problem. Most commonly, treatment begins with eye drops that are designed to lower the pressure in the eye. These drops are from once to four times daily, depending on the medication. These drops are designed to decrease the amount of fluid produced in the eye, or to increase the amount of fluid drained from the eye. There are also oral medications that are available to lower the eye pressure. Like all medications, these eye drops can have side effects. When treatment with eye drops is started, you should discuss with your doctor the potential side effects and interactions with other medication that you may be taking.<\/p>

Another way of treating glaucoma is with a laser. This laser is designed to increase the amount of fluid drained from the eye, thereby lowering the pressure in the eye. The laser treatment is usually performed in the office, takes only a few minutes, and is normally painless. The third way to treat glaucoma is with microsurgery in the operating room. In this procedure, a small drainage hole is created in the eye, usually behind the eye in the eye socket. This drainage allows the eye pressure to be lowered, thereby preventing further damage from glaucoma.<\/p>

Open angle glaucoma is generally a disease that stays with an affected person for life. Whether the treatment has been with medications, laser, or microsurgery, the victim of glaucoma must continue to be monitored by the ophthalmologist several times a year. Your doctor will monitor the eye pressure, the appearance of your optic nerve, and will periodically test the peripheral, or side, vision (visual field) to be certain that the disease has been stabilized, and that further loss of vision will not occur.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Your ophthalmologist will check to see if you have a narrow drainage area in your eye in order to know if you are at risk of developing narrow angle glaucoma. Your doctor will perform an examination known as gonioscopy to evaluate your risk. If you are at risk for narrow angle glaucoma, your ophthalmologist will recommend a preventive laser treatment. If you already have narrow angle glaucoma, this sometimes is cured with laser treatment. Sometimes narrow angle glaucoma is a chronic condition that is treated with the same medicines or microsurgery described above for open angle glaucoma.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

The best way to prevent visual loss from glaucoma is through regular eye examinations by an ophthalmologist. Eye examinations are recommended for adults as follows: once yearly between the ages of 19-35, three times between the ages of 35-50, every two years between the ages of 50-65, and yearly thereafter. More frequent examinations are recommended if you have any problems with your vision or have a family history of glaucoma (every 1-2 years). More frequent examinations are also recommended if you have certain medical conditions, such as diabetes or high blood pressure. For children, routine yearly screening examinations by the pediatrician are usually sufficient, unless an eye appears abnormal, or the child has trouble seeing.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t
