Diabetic Retinopathy

Diabetic retinopathy is the most common eye complication of diabetes and is a leading cause of blindness in adults. Diabetic retinopathy develops as a result of chronic elevation of blood sugars which then damages the internal lining of small retinal blood vessels. Damaged retinal blood vessels then are prone to leaking. This can lead to macular edema and vision loss. As blood vessels get progressively damaged from elevated blood sugars, these retinal vessels can also become blocked. This leads to a depletion of good blood flow to the retina. The retina then releases chemical signals to grow new blood vessels to feed itself (Proliferative Diabetic Retinopathy). However, these new blood vessels themselves are fragile and prone to breaking which can then cause vitreous hemorrhages and sometimes severe loss of vision. Tractional Retinal Detachments can also result from growth of these abnormal blood vessels.

Patients who develop diabetic retinopathy may initially not notice any change in their vision. But in its advanced stages, the disease can cause blurred or cloudy vision, floaters and blind spots – and, eventually, blindness. This damage may become irreversible without treatment.

Early stages of diabetic retinopathy do not usually require any treatment but patients must keep strict control of their blood sugar level to prevent the disease from progressing. If the disease does progress, treatment by a retinal specialist may be necessary to preserve your vision. The two most important causes of vision loss are now discussed below.

Diabetic Macular Edema

Treatment for diabetic macular edema typically involves one of the following options: observation alone with better control of blood sugars, ocular injections of medications, or the use of a laser. If a patient has significant macular edema, then injectable medications can slow or halt the release of fluid out of injured diabetic retinal blood vessels and thereby reduce macular fluid. Available drugs that do exactly this include: Avastin TM (off-label), Lucentis TM, and periocular or intra-ocular steroid injections. Avastin TM and Lucentis TM may require monthly injections to reduce diabetic macular edema and hence allow the macula to see better. Because diabetes itself is a chronic disease, steady ongoing retinal therapy may be needed to prevent you from experiencing vision loss over time. Our retinal specialist can discuss the risks and benefits of injectable therapies.

Another category of treatment for diabetic macular edema is: LASER. During this procedure, small laser spots are placed in the macula to limit leakage from damaged capillaries and also stimulate the removal of fluid out of the retina. The reduction in macular fluid will improve the function of the retina and help prevent vision loss and, in certain patients, even improve vision. Focal laser treatment is performed in our office under topical anesthesia and repeat treatments may be necessary to stabilize your disease.

Dr. Ilyas is one of the first retina surgeons in this region to offer a cutting-edge form of macular laser called "Micropulse Laser Therapy" (Iridex ™) for treatment of diabetic macular edema. Micropulse Laser can effectively treat patients with Diabetic Macular Edema while preserving the health and well-being of the macular tissue. Micropulse laser works by chopping a continuous wave of laser into tiny low energy pulses with rest periods in between. This "micropulsing" technique allows the retinal tissue to cool in between laser pulses without promoting thermal injury or death of tissue. Conventional lasers (still commonly used for diabetic macular edema) can leave injurious scars in the macula which in turn can create blind spots near the central vision or rarely central vision loss. Micropulse Laser avoids any damaging laser scars and preserves the important macular tissue which gives us our sharp vision while accomplishing the goal of reducing macular fluid. Micropulse Laser therapy is also utilized in the treatment of several other retinal diseases including Central Serous Retinopathy.

Proliferative Diabetic Retinopathy

Proliferative Diabetic Retinopathy with Vitreous Bleeding
Treatment of Proliferative Diabetic Retinopathy usually requires laser surgery called Panretinal or Scatter Laser Treatment. This treatment is used to shrink the newly developed blood vessels using up to 1,200 or more laser burns in the peripheral retina. Scatter laser treatment is most effective before newly grown blood vessels have started to bleed, and may slightly reduce patients' color and night vision, while preserving your central vision. Severe vitreous bleeding may require surgery called vitrectomy, or removal of the vitreous, to remove blood from the center of the eye.

Left unchecked, Proliferative Diabetic Retinopathy can lead to tractional retinal detachments that can permanently disable the vision. If the retinal detachment is severe enough, surgical intervention (vitrectomy with membrane peel) may be necessary to prevent total blindness. At Retina & Vitreous Consultants, we provide expert surgical care of these complex retinal detachments.

What can I do to prevent or limit my risk of Diabetic Retinopathy?

It is important for patients with diabetes to have dilated eye exams once a year to check for any signs of diabetic eye disease. You can also minimize your risk of developing diabetic eye disease by keeping your blood sugar and blood pressure under excellent control, eating a healthy diet, and exercising regularly.
