Commonly asked questions ?

Blood vessels damaged from diabetic retinopathy can cause vision loss in two ways:

  • Fragile, abnormal blood vessels can develop and leak blood into the center of the eye, blurring vision. This is proliferative retinopathy and is the fourth and most advanced stage of the disease
  • Fluid can leak into the center of the macula, the part of the eye where sharp, straight-ahead vision occurs. The fluid makes the macula swell, blurring vision. This condition is called macular edema. It can occur at any stage of diabetic retinopathy, although it is more likely to occur as the disease progresses. About half of the people with proliferative retinopathy also have macular edema.

All people with diabetes–both type 1 and type 2–are at risk. That’s why everyone with diabetes should get a comprehensive dilated eye exam at least once a year. The longer someone has diabetes, the more likely he or she will get diabetic retinopathy.

Diabetic retinopathy and macular edema are detected during a comprehensive eye exam that includes:

  • Visual acuity test
  • Dilated eye exam Your doctor checks your retina for early signs of the disease, including:
  • Leaking blood vessels.
  • Retinal swelling (macular edema).
  • Pale, fatty deposits on the retina–signs of leaking blood vessels.
  • Damaged nerve tissue.
  • Any changes to the blood vessels.

If your doctor believes you need treatment for macular edema, he or she may suggest a fluorescein angiogram. The test allows your doctor to identify any leaking blood vessels and recommend treatment.

During the first three stages of diabetic retinopathy, no treatment is needed, unless you have macular edema. To prevent progression of diabetic retinopathy, people with diabetes should control their levels of blood sugar, blood pressure, and blood cholesterol.

Proliferative retinopathy is treated with laser surgery. This procedure is called Pan Retinal Photocoagulation which helps to shrink the abnormal blood vessels. Your doctor places 1,000 to 2,000 laser burns in the areas of the retina away from the macula, causing the abnormal blood vessels to shrink. Because a high number of laser burns are necessary, two or more sessions usually are required to complete treatment. Although you may notice some loss of your side vision, Laser Photocoagulation can save the rest of your sight.

Laser Photocoagulation works better before the fragile, new blood vessels have started to bleed. That is why it is important to have regular, comprehensive dilated eye exams. Even if bleeding has started, laser treatment may still be possible, depending on the amount of bleeding.

If the bleeding is severe, you may need a surgical procedure called a vitrectomy. During a vitrectomy, blood is removed from the center of your eye.

Macular edema is treated with laser surgery. This procedure is called focal laser photocoagulation. Your doctor places up to several hundred small laser burns in the areas of retinal leakage surrounding the macula. These burns slow the leakage of fluid and reduce the amount of fluid in the retina. The surgery is usually completed in one session. Further treatment may be needed.

A patient may need focal laser surgery more than once to control the leaking fluid. If you have macular edema in both eyes and require laser surgery, generally only one eye will be treated at a time, usually several weeks apart.

Focal laser photocoagulation stabilizes vision. In fact, it reduces the risk of vision loss by 50 percent.

AMD is a common eye disease mostly seen in people over the age of 50 years that gradually destroys sharp, central vision. In some cases, AMD advances so slowly that people notice little change in their vision. At this stage, it may be detected on routine retina check-up. But in others, the disease progresses faster and may lead to a loss of vision in one or both eyes. AMD usually involves both eyes, although one may be affected long before the other. AMD causes no pain and almost never leads to total blindness.

AMD cannot be prevented. Early diction is important to prevent severe visual loss. Protecting your eyes from the sun, eating a well balanced diet with plenty of fresh fruits and vegetables and stopping smoking may all help to delay the progress of AMD

Dry AMD: Once dry AMD reaches the advanced stage, no form of treatment can prevent vision loss. However, treatment can delay and possibly prevent early dry AMD from progressing to the advanced stage, in which vision loss occurs. Nutrition and antioxidants- The role of antioxidants is not clear but supplementation with Lutein ,zeaxanthin ,Vitamin C and E and other minereals has shown a beneficial effect in slowing the progression of disease. Quit smoking.

Wet AMD: 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. Each treatment may slow the rate of vision decline or stop further vision loss, but the disease and loss of vision may progress despite treatment

Laser Phtocoagulation: This procedure uses a laser to destroy the fragile, leaky blood vessels. A high energy beam of light is aimed directly onto the new blood vessels and destroys them, preventing further loss of vision. However, laser treatment also may destroy some surrounding healthy tissue and some vision. Only a small percentage of people with wet AMD can be treated with laser surgery. Laser surgery is more effective if the leaky blood vessels have developed away from the fovea, the central part of the macula

Photodynamic therapy: A drug caled verteporfin is injected into your arm. Next, a light is shined into your eye for about 90 seconds. The light activates the drug. The activated drug destroys the new blood vessels and leads to a slower rate of vision decline. Treatment results often are temporary. You may need to be treated again.

Transpupillary Thermotherapy: A special type of laser is used to heat up the membrane without destroying the overlying retina.

Injections(Anti VEGF therapy): Wet AMD can now be treated with a new drug that is injected into the eye (anti-VEGF therapy). Abnormally high levels of a specific growth factor occur in eyes with Wet AMD and promote the growth of abnormal new blood vessels. This drug treatment blocks the effects of the growth factor. You will need multiple injections, usually given about six weeks apart. The eye is numbed before each injection. After the injection, you will remain in the doctor’s office for a while and your eye will be monitored. As with photodynamic therapy, the main benefit for patients treated with the drug is to slow vision loss from AMD.

A retinal detachment occurs when the retina is pulled away from its normal position in the back of the eye. The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. Retinal detachment can cause permanent vision loss if not treated in time.

  • Flashes of light (photopsia) – mostly experienced in the temporal (outside away from the nose) part of vision
  • Floaters- black cobweb like spots moving in front of eye
  • A curtain like shadow coming in field of vision
  • Sudden Vision Loss when macula is detached

Retinal hole or breaks are treated with laser photocoagulation or cryopexy (a freeze treatment) as outdoor procedure. During laser treatment, dot like burns are placed around the hole to “weld” the retina. In Cryopexy the area around the hole is frozen and it helps reattach the retina.Retinal detachments are treated with surgery viz sceral buckling and complex vitreoretinal surgery involving use of Silicon oil or gases.In scleral bucking, a silicon band, is placed anchored with stitches around the eyeball to gently push the wall of the eye against the detached retina.In vitrectomy, the surgeon makes tiny incisions in the sclera (white portion of the eye). Vitrectomy instruments are placed inside the eye to take out the vitreous gel and it is replaced with silicon oil or gases to push the retina in place .Laser or cryopexy is done around the breaks to seal it.With modern vitreoretinal instrumentation, around 90 percent of cases with a retinal detachment can be successfully treated, Visual results are good if the retinal detachment is repaired before the macula (the centre region of the retina responsible for fine, detailed vision) detaches. This is important to contact your retina surgeon in time when you notice any flashes or floaters or a curtain in field of vision.

A retinal detachment can occur at any age, but it is more common in people over age of 40.Common risk factors for developing RD are:

  • High Myopia –Especially more than 5 Dioptre. After cataract surgery
  • Retinal detachment in the other eye
  • Family history of retinal detachment
  • Presence of other eye diseases such as retinoschisis, degenerative myopia, or lattice degeneration
  • Following an eye injury

It is an extremely valuable test in which a series of photographs of the retina are taken with the help of a special camera to analyze the blood circulation of choroids and retina.

This test is done to evaluate, diagnose and guide treatment for certain diseases of retina like Diabetic retinopathy, Age related macular degeneration and Retinal vascular blockage etc.
