The Facts About Retinal Detachment

•Retinal Detachment is difficult to prevent, but prompt treatment may save your vision.

The light-sensitive tissue lining the back of your eye is called the retina. The retina converts the images that enter through your eye lens into electrical signals that your brain can interpret Our eyes are filled with a clear vitreous gel between the retina and lens .

. Retinal tissue sometimes pulls away from the blood vessels it needs for oxygen and nutrients.. When that gel shrinks, it can pull and tear the retina creating one common cause of retinal detachment.. The most common symptoms include floaters that look like spots and lines before your eyes or sudden flashes of light.You may also feel like a curtain is falling across your vision or you may notice a loss in side vision.

•extra care after age 50.helps as the vitreous gel in our eyes naturally shrinks with age.

•You may be at increased risk if one or more family members have had a detached retina. Put together a family medical history and share it with your doctor.Myopic eyes are longer and tend to stretch the retina. Talk with your doctor about your risks.

• Cataract surgery can work wonders, but it can also increase the risk for detached retinas. Manage diabetes. Advanced diabetes is linked to a specific form of retinopathy.

•It’s relatively rare for a blow to the eye to cause retinal detachment. Still, you can lower your odds even more by using safety gear during hazardous work or sports.

• Painless procedures with an ophthalmoscope or ultrasound can identify the issue and potentially save your vision.

• Surgery is required to treat a detached retina. and usually include laser surgery, freezing, or injecting an air bubble. Aftercare may include medication, rest and keeping your head still.

•On the other hand, holes can form in the retina as a normal part of aging. No treatment is needed so long as you remain free of any symptoms.

•You will probably need at least one new pair of glasses after your operation.

. Most surgeries to repair a detached retina are successful, so immediate medical care makes all the difference.

  • This is very helpful. Do you have any information about retinopathy to share with the group?

  • No.i will try later

  • Okay, sounds good.

    Diabetes-Related Sight Loss

    The effect of diabetes on the eye is called diabetic retinopathy. Diabetic retinopathy is a common complication of diabetes, it may not have any symptoms or may not affect sight in the early stages but, as the condition progresses, eventually the sight will be affected. When the condition is caught early, treatment is effective at reducing or preventing damage to sight.

    Diabetic related sight loss is the most common form of blindness in people of working age in Ireland. In about 10% of cases, diabetic macular oedema (DME) may occur where blood vessels leak their contents into the macular region of the retina and this may cause a more rapid form of vision loss.

    The earliest phase of diabetic retinopathy is known as ‘background diabetic retinopathy’. Often there are no symptoms in the early stages of the disease, nor is there any pain. In this phase, the arteries in the retina become weakened and leak, forming small haemorrhages. These leaking vessels often lead to swelling or oedema in the retina. As the disease progresses, some blood vessels that nourish the retina become blocked, over time worsening and depriving several areas of the retina with their blood supply.

    In advanced diabetic retinopathy the signals sent by the retina for nourishment trigger the growth of new blood vessels. This condition is called proliferative retinopathy. These new blood vessels are abnormal and fragile. They grow along the retina and along the surface of the clear gel that fills the inside of the eye. By themselves, these blood vessels do not cause symptoms or vision loss. However, they have thin, fragile walls. If they leak blood, severe vision loss and even blindness can result.

    A condition known as diabetic macular oedema occurs when blood leaks into the centre of the retina, known as the macula, the part of the eye where sharp, straight-ahead vision occurs. The fluid makes the macula swell, blurring vision. This can occur at any stage of diabetic retinopathy, although it is more likely to occur as the disease progresses.

    The good news is that by regular and effective retina screening, diabetic retinopathy can be caught early and effectively treated. The national diabetic retina screening programme for diabetic retinopathy (Diabetic RetinaScreen) has been rolled out nationwide for everyone over the age of 12 who is affected by diabetes in Ireland. If you have diabetes it is extremely important that you reply to the letter you have received in order to express your interest in taking part in the eye screening. More information is available or by calling 1890 45 45 55.

    Prevention of diabetic retinopathy is the most important step to take for anyone with diabetes. Researchers have found that diabetic patients who are able to maintain appropriate blood sugar and blood pressure levels have fewer eye problems than those with poor control. Diet and exercise play important roles in the overall health of people with diabetes.

    People with diabetes can also greatly reduce the possibilities of eye complications by going to their routine examinations with an eye doctor and taking part in the national screening programme. Many problems can be treated with much greater success when caught early.

    Diabetic retinopathy is treated in many ways depending on the stage of the disease and the specific problem that requires attention. The doctor relies on several tests to monitor the progression of the disease and to make decisions for the appropriate treatment. Laser eye surgery called pan retinal photocoagulation (PRP) is one treatment choice to prevent the blood vessels from leaking, or to get rid of the growth of abnormal, fragile vessels. A new class of drugs has recently become available to treat macular oedema and they are often used in conjunction with the laser therapy. These are anti-VEGF (Vascular Endothelial Growth Factor) drugs and they target the substance in the body which is responsible for the development of blood vessels. In diabetic macular oedema, too much VEGF is produced in the eye, and these drugs block the production of these new, abnormal vessels.

    Vitrectomy is another surgery commonly needed for diabetic patients who suffer a vitreous haemorrhage (bleeding in the gel-like substance that fills the centre of the eye). During a vitrectomy, the retina surgeon carefully removes blood, fibrous tissue and vitreous from the eye, relieving traction on the retina and preventing retinal detachment. If retinal detachments or tears occur, they are often sealed with laser surgery.Retinal detachment requires surgical treatment to reattach the retina to the back of the eye. The prognosis for visual recovery is dependent on the severity of the detachment.

    Exciting research for diabetes and diabetic retinopathy is ongoing. Irish researchers from NUI Galway and Queen’s University Belfast are part of an international collaboration who are assessing if stem cells derived from bone marrow can control glucose levels and stop some of the damage caused by six diabetic complications, including diabetic retinopathy. Fighting Blindness supported researchers in UCD and the Mater Hospital are also designing tools that can detect, treat and prevent vision loss in people with diabetes. They are studying the molecular basis of diabetic retinopathy and they have discovered that there are resident populations of cells within the eye that can be manipulated in order to promote repair.

    Information about clinical trials that are currently being conducted worldwide can be found on and can be searched by condition and trial location.

  • Sounds good! Thank you.

  • I've been told by my friendly local optician that the best way to avoid diabetic eye problems is to keep your blood sugar levels under strict control - all the time. You might still have problems but you're definitely giving yourself more of a chance if you keep your levels under control.
