Diabetic retinopathy retinal laser surgery -
AMD affects the macula, the part of the eye that allows you to see fine detail. AMD causes no pain. In some cases, AMD advances so slowly that people notice little change in their vision.
In others, the disease progresses faster and may lead to a loss of vision in both eyes. AMD is a leading cause of vision loss in Americans 60 years of age and older.
The macular is located in the center of the retina, the light-sensitive tissue at the back of the eye. The retina instantly converts light, or an image, into electrical impulses. The retina then sends these impulses, or nerve signals, to the brain. Wet AMD occurs when abnormal blood vessels behind the retina start to grow under the macula.
These new blood vessels tend to be very fragile and often leak blood and fluid. The blood and fluid raise the macula from its normal place at the back of the eye. Damage to the macula occurs rapidly.
With wet AMD, loss of central vision can occur quickly. Wet AMD is also known as advanced AMD. It does not have stages like dry AMD. An early symptom of wet AMD is that straight lines appear wavy.
If you notice this condition or other changes to your vision, contact your eye care professional at once. You need a comprehensive dilated exam. One key identifier for AMD is the collection of small, round, white-yellow, fatty deposits called drusen in the central part of the retina, the macula.
Dry AMD occurs when the light-sensitive cells in the macula slowly break down, gradually blurring central vision in the affected eye. As dry AMD gets worse, you may see a blurred spot in the center of your vision.
Over time, as less of the macula functions, central vision is gradually lost in the affected eye. The most common symptom of dry AMD is slightly blurred vision.
You may have difficulty recognizing faces. You may need more light for reading and other tasks. Dry AMD generally affects both eyes, but vision can be lost in one eye while the other eye seems unaffected.
Drusen are yellow deposits under the retina. They often are found in people over age Your eye care professional can detect drusen during a comprehensive dilated eye exam. Drusen alone do not usually cause vision loss. In fact, scientists are unclear about the connection between drusen and AMD.
These changes can cause serious vision loss. If you have vision loss from dry AMD in one eye only, you may not notice any changes in your overall vision.
With the other eye seeing clearly, you still can drive, read, and see fine details. You may notice changes in your vision only if AMD affects both eyes. If blurriness occurs in your vision, see an eye care professional for a comprehensive dilated eye exam.
Ninety percent of all people with AMD have this type. Scientists are still not sure what causes dry AMD. For dry AMD: the most common early sign is blurred vision.
As fewer cells in the macula are able to function, people will see details less clearly in front of them, such as faces or words in a book. Often this blurred vision will go away in brighter light. If the loss of these light-sensing cells becomes great, people may see a small-but growing- blind spot in the middle of their field of vision.
For wet AMD: the classic early symptom is that straight lines appear crooked. This results when fluid from the leaking blood vessels gathers and lifts the macula, distorting vision.
Your eye care professional may suspect AMD if you are over age 60 and have had recent changes in your central vision. To look for signs of the disease, he or she will use eye drops to dilate, or enlarge your pupils.
Dilating the pupils allows your eye care professional to view the back of the eye better. The doctors at Singer Haley Vision Center may do other tests to learn more about the structure and health of your eye.
During an eye exam, you may be asked to look at an Amsler grid. The pattern of the grid resembles a checkerboard. You will cover one eye and state at a black dot in the center of the grid. While staring at the dot, you may notice that the straight lines in the pattern appear wavy.
You may notice that some of the lines are missing. These may be signs of AMD. If the doctors at Singer Haley Vision Center think you need treatment for wet AMD, he or she may suggest a fluorescein angiogram. In this test, a special dye is injected into your arm.
Pictures are taken as the dye passes through the blood vessels in your retina. The test allows your eye care professional to identify any leaking blood vessels and recommend treatment. Wet AMD can be treated with laser surgery, photodynamic therapy, and injections into the eye.
None of these treatments is a cure for wet AMD. The disease and loss of vision may progress despite treatment. Once dry AMD reaches the advanced stage, no form of treatment can prevent vision loss. However, treatment can delay and possibly prevent intermediate AMD from progressing to the advanced stage, in which vision loss occurs.
The specific daily amounts of antioxidants and zinc used by the study researchers were milligrams of vitamin C, International Units of vitamin E, 15 milligrams of beta-carotene often labeled as equivalent to 25, International Units of vitamin A , 80 milligrams of zinc as zinc oxide, and two milligrams of copper as cupric oxide.
Copper was added to the AREDS formulation containing zinc to prevent copper deficiency anemia, a condition associated with high levels of zinc intake. People who are at high risk for developing advanced AMD should consider taking the formulation.
You are at high risk for developing advanced AMD if you have either:. Your eye care professional can tell you if you have AMD, its stage, and your risk for developing the advanced form. The AREDS formulation is not a cure for AMD.
It will not restore vision already lost from the disease. However, it may delay the onset of advanced AMD.
It may help people who are at high risk for developing advanced AMD keep their vision. Can people with early stage AMD take the AREDS formulation to help prevent the disease from progressing to the intermediate stage? There is no apparent need for those diagnosed with early stage AMD to take the AREDS formulation.
The study did not find that the formulation provided a benefit to those with early stage AMD. If you have early stage AMD, a comprehensive dilated eye exam every year can help determine if the disease is progressing. If early stage AMD progresses to the intermediate stage, discuss taking the formulation with your doctor.
Can diet alone provide the same high levels of antioxidants and zinc as the AREDS formulation? The high levels of vitamins and minerals are difficult to achieve from diet alone.
However, previous studies have suggested that people who have diets rich in green leafy vegetables have a lower risk of developing AMD. Can a daily multivitamin alone provide the same high levels of antioxidants and zinc as the AREDS formulation?
If you are already taking daily multivitamins and your doctor suggests you take the high-dose AREDS formulations, be sure to review all your vitamin supplements with your doctor before you begin.
Because multivitamins contain many important vitamins not found in the AREDS formulation, you may want to take a multivitamin along with the AREDS formulation. For example, people with osteoporosis need to be particularly concerned about taking vitamin D, which is not in the AREDS formulation.
If you have dry AMD, you should have a comprehensive dilated eye exam at least once a year. Your eye care professional can monitor your condition and check for other eye diseases. Also, if you have intermediate AMD in one or both eyes, or advanced AMD in one eye only, your doctor may suggest that you take the AREDS formulation containing the high levels of antioxidants and zinc.
Because dry AMD can turn into wet AMD at any time, you should get an Amsler grid from your eye care professional.
Use the grid every day to evaluate your vision for signs of wet AMD. This quick test works best for people who still have good central vision. Check each eye separately. Cover one eye and look at the grid.
Then cover your other eye and look at the grid. If you detect any changes in the appearance of this grid or in your ever day vision while reading the newspaper or watching television, get a complete dilated eye exam. If you have wet AMD and your doctor advises treatment, do not wait.
After laser surgery or photodynamic therapy, you will need frequent eye exams to detect any recurrence of leaking blood vessels. In addition, check your vision at home with the Amsler grid. If you detect any changes, schedule an eye exam immediately.
Normal use of your eyes will not cause further damage to your vision. If you have lose some sight from AMD, ask your eye care professional about low vision services and devices that may help you make the most of your remaining vision. Ask for a referral to a specialist in low vision.
Many community organizations and agencies offer information about low vision counseling, training, and other special services for people with visual impairments. A nearby school of medicine or optometry may provide low vision services.
The National Eye Institute is conducting and supporting a number of studies to learn more about AMD. For example, scientists are:. This research should provide better ways to detect, treat, and prevent vision loss in people with AMD.
Change Text Size A A A. This is a healthy retina. Symptoms of diabetic retinopathy include: Seeing spots or floaters in your field of vision Blurred vision Having a dark or empty spot in the center of your vision Difficulty seeing well at night In patients with diabetes, prolonged periods of high blood sugar can lead to the accumulation of fluid in the lens inside the eye that controls eye focusing.
What causes diabetic retinopathy? Blood vessels damaged from diabetic retinopathy can cause vision loss: Fluid can leak into the macula, the area of the retina which is responsible for clear central vision.
Diabetic retinopathy is classified into two types: Non-proliferative diabetic retinopathy NPDR is the early stage of the blood disease in which symptoms will be mild or non-existent. The microanuerysms may leak fluid to the retina, which may lead to swelling of the macula.
Proliferative diabetic retinopathy PDR is the more advanced form of the disease. At this stage, circulation problems cause the retina to become oxygen deprived.
As a result new fragile blood vessels can begin to grow in the retina and into the vitreous, the gel-like fluid that fills the back of the eye. Once your vision starts to stabilise, they'll be stopped or given less frequently.
Injections of steroid medication may sometimes be given instead of anti-VEGF injections, or if the anti-VEGF injections do not help. There's also a risk that the injections could cause blood clots to form, which could lead to a heart attack or stroke. This risk is small, but it should be discussed with you before you give your consent to treatment.
The main risk with steroid injections is increased pressure inside the eye. If you cannot have anti-VEGF injections or they have not worked for you, you may be offered an eye implant called an intravitreal implant brand name Ozurdex containing a steroid medicine called dexamethasone.
This is a tiny implant that's injected into your eye using a special applicator. You'll be given a local anaesthetic first to numb your eye. The implant slowly releases dexamethasone over a few months.
This reduces swelling in your eye, and can help to improve your eyesight. Side effects usually get better after a few days. Speak to your treatment team if you have eye pain or changes to your eyesight.
Surgery may be carried out to remove some of the vitreous humour from the eye. This is the transparent, jelly-like substance that fills the space behind the lens of the eye. During the procedure, the surgeon will make a small incision in your eye before removing some of the vitreous humour, removing any scar tissue and using a laser to prevent a further deterioration in your vision.
Vitreoretinal surgery is usually carried out under local anaesthetic and sedation. This means you will not experience any pain or have any awareness of the surgery being performed. You should be able to go home on the same day or the day after your surgery.
For the first few days, you may need to wear a patch over your eye. This is because activities such as reading and watching television can quickly tire your eye to begin with. You will probably have blurred vision after the operation. This should improve gradually, although it may take several months for your vision to fully return to normal.
Your surgeon will advise you about any activities you should avoid during your recovery. There's also a small chance that you will need further retinal surgery afterwards. Your surgeon will explain the risks to you. Page last reviewed: 16 December Next review due: 16 December Home Health A to Z Diabetic retinopathy Back to Diabetic retinopathy.
