Ranibizumab (Lucentis) was noninferior to panretinal photocoagulation at treating proliferative diabetic retinopathy in a 2-year randomized noninferiority trial. Panretinal photocoagulation (PRP) is the standard treatment for reducing severe visual loss from proliferative diabetic retinopathy. The study included 305 participants (394 eyes) with proliferative diabetic retinopathy in one or both eyes at 55 clinical sites across the country.
Approximately half of the eyes assigned to the PRP group required more than 1 round of laser treatment (39% required 2 rounds, and 7% required 3 rounds).
The study permitted the use of ranibizumab for the treatment of diabetic macular edema (one of its indications) in both groups, if necessary.
Rates of serious systemic adverse events, including major cardiovascular events, were similar between the 2 groups.

Diabetic retinopathy (DR) is the most common type of diabetic eye disease and the leading cause of blindness in American adults. The features of mild nonproliferative retinopathy are some of the earlier stages of diabetic retinopathy.
As the retinopathy progresses and more blood vessels have now been affected, larger areas of the retina are deprived of blood flow. At this advanced stage, the signals sent by the retina for nourishment trigger the growth of new blood vessels that grow along the retina and into other parts of the eye. Fluid can leak into the macula, the center of the retina that is responsible for central vision. The results of large clinical trials have shown that better control of blood sugar levels slows the onset and progression of retinopathy. Proliferative retinopathy frequently produces symptoms as a result of bleeding into the vitreous cavity. Your retina specialist may also order special testing to help stage the retinopathy or decide if treatment is needed. During the stages of mild and moderate non-proliferative diabetic retinopathy, no treatment is needed unless macula edema is present.
Macular edema is most effectively treated with focal laser treatment that is usually completed in one session. Both focal and grid laser treatments are performed in your doctor's office with the lights dimmed.
Laser treatment will at best stabilize vision, but generally cannot restore vision that has been lost. It is highly uncommon to experience a decline in vision following treatment, and with the majority of patients who do, it is a temporary condition. Certain drugs have been used to successfully reduce macular edema and new blood growth resulting from diabetic retinopathy. There are two major therapies for proliferative diabetic retinopathy—scatter laser treatment and vitrectomy. In some instances, anti-VEGF drugs may be used in conjunction with laser to treat severe forms of proliferative diabetic retinopathy.
You may require a surgical procedure called a vitrectomy if bleeding is severe, if it does not clear up on its own or if you develop a retinal detachment related to your diabetic retinopathy. Prior to surgery, your doctor will explain the rare but possible complications of vitrectomy surgery. Are scatter laser treatment and vitrectomy effective in treating proliferative retinopathy?
Ask your retina specialist about referring you to a low vision specialist and about low vision services and devices that may help you make the most of your remaining vision. This is the earliest stage where blood vessels in the retina leak fluid, sometimes fat and blood into retinal tissue. This results in development of Micro aneurysms, edema (swelling) and hard exudates in retina. Macular Edema: Due to the fluid leaked from the capillaries, there is a swelling at the macula which leads to impairment of vision from mild to severe degrees.
Macular Ischemia occurs when small blood vessels (capillaries) close at macula which leads to drop in vision. FFA (Fundus Fluoresceine Angiography): Fluoresceine dye is injected in the vein and photographs are taken of both retina with FUNDUS CAMERA. Provides additional information regarding thickness and structure of macula and relationship of vitreous fluid to macula. It consists of 2-3 sittings of laser treatment to entire retina except the optic disk and macula. Some patients present at this stage, some patients worsen despite adequate laser treatment and may have vitreous hemorrhage, retinal detachment and Neovascular Glaucoma.
Your pupils are dilated with eye drops and retina is examined by special equipments like Indirect Ophthalmoscope and Slit Lamp Bio Microscope. Ranibizumab blocks the effects of vascular endothelial growth factor (VEGF) and is indicated for the treatment of wet age-related macular degeneration, macular edema following retinal vein occlusion, and diabetic macular edema.


However, PRP can cause permanent peripheral visual field loss and decreased night vision and may exacerbate diabetic macular edema, which makes alternative treatments desirable, according to the study background. Sieving, MD, PhD, Director of the National Institutes of Healtha€™s National Eye Institute, which funded the trial. Ranibizumab (0.5 mg) was administered via injection into the eye once per month for 3 consecutive months, and then as needed until the disease resolved or stabilized. Slightly more than half (53%) of eyes in the laser group received ranibizumab injections to treat diabetic macular edema.

Injection Instead of Laser Photocoagulation May Be Viable Treatment Option for Diabetic Retinopathy.
Diabetes causes damage to the blood vessels of the retina, a thin and delicate tissue that is responsible for vision. At this point, small areas of balloon-like dilation of blood vessels, called microaneurysms, start to appear along with other findings such as small spot hemorrhages and cotton wool spots.
Many more microaneurysms, hemorrhages and cotton wool spots emerge and there is further damage to the retinal blood vessels. This results in the retina producing new blood vessels in an attempt to enhance nourishment. These blood vessels are abnormal and fragile, often leading to the development of new or worsening existing symptoms and frequent vision loss. Just like a damaged garden hose, the damaged blood vessels surrounding the macula leak, and fluid accumulates around the surrounding macular tissue, causing it to swell and creating blurry vision.
These fragile vessels tend to break and produce bleeding along the retina and vitreous cavity. The longer someone has diabetes, the more likely he or she will develop diabetic retinopathy.
To protect vision, every pregnant woman with diabetes should have a comprehensive dilated eye exam as early as possible. If you are diabetic, be sure to schedule a comprehensive dilated eye exam at least once a year. In general, diabetic patients who kept their blood sugar levels as close to normal as possible also had significantly less kidney and nerve disease. After checking your vision and eye pressure, drops are placed in your eyes to widen, or dilate, the pupils.
To prevent the progression of diabetic retinopathy, people with diabetes should control their blood sugar, blood pressure and cholesterol. Your doctor seals leaking blood vessels (microaneurysms) with light heat generated by a laser. Before the treatment, your physician will dilate your pupil and apply drops to numb the eye.
This is yet another reason that treating diabetic retinopathy early is the best way to prevent vision loss.
The agents used, steroids and anti-vascular endothelial growth factor drugs (VEGF), are injected into the eye to reduce leakage, swelling or new blood vessel growth. Your doctor places laser spots throughout the entire peripheral retina, causing the abnormal blood vessels to shrink. It usually subsides at the end of the procedure, but some patients report mild discomfort or a mild headache lasting for the rest of the day. Although they both have high success rates, neither one cures diabetic retinopathy, but rather reduces the risk of new bleeding. Closed circuit television with electronic magnification and image intensification is a commonly-used aide as are lens magnifiers combined with a brighter light.
The extra unutilized sugar acts like poison for the whole body affecting every organ especially the eyes, heart, kidney and brain. Diabetic Maculopathy (DM) can be present in either stage and be responsible for loss of vision.
Many people with NPDR have normal vision and the treatment consists of STRICT CONTROL of Diabetes and associated systemic illnesses.
The findings were published in the November 13 Journal of the American Medical Association. For participants with both eyes affected by the disease, one eye was assigned to the PRP group, and the other was assigned to the ranibizumab group. About 6% of eyes in the ranibizumab group received PRP therapy, mostly to treat retinal detachment or bleeding.
Diabetic retinopathy usually affects both eyes, but early detection and prompt treatment can minimize vision loss.
It's important to note that not all patients with mild nonproliferative retinopathy will notice a change in their vision.
The danger is that such damage can result in reduced blood flow to the surrounding retinal tissue leading to vision loss.


This is called diabetic macular edema and it can occur at any stage of diabetic retinopathy. This is called a vitreous hemorrhage and commonly causes floaters and, in severe cases, leads to vision loss. If that occurs, see your retina specialist as soon as possible; you may need treatment before more serious bleeding occurs. A retina specialist uses a special magnifying lens to examine your retina for signs of diabetic retinopathy. Pictures are taken as the dye passes through the blood vessels in your retina, allowing for the identification of any leaking blood vessels that may require treatment.
These treatment spots slow the leakage of fluid and reduce the amount of fluid in the macula. Unfortunately, the benefit of these drugs is often temporary, and they need to be injected multiple times to sustain their effects. Because it's necessary to use a large number of laser spots, more than one session is often required to complete treatment.
Your doctor inserts tiny instruments through small incisions in the sclera (the white portion of the eye) and removes the gel and blood from the center of the eyeball. Vitrectomy surgery can—and usually does—improve vision, but scatter laser is employed to stabilize vision. Patients are often given the opportunity to test low vision products at home before purchasing them. Retina needs a lot of oxygen and has plenty of blood vessels, so it gets affected and the condition is known as DIABETIC RETINOPATHY. Periodic follow up examinations every year is very important to catch the disease at the earliest.
In others, abnormal new blood vessels grow on the surface of the retina that can lead to bleeding and retinal detachment.
You can develop both proliferative retinopathy and macular edema and still see normally, but you may remain at high risk for vision loss.
When symptoms do occur, they range from mildly blurred central vision to complete vision loss. Your doctor may also recommend Ocular Coherence Tomography, or OCT, to check for diabetic macular edema. Focal laser treatment slows the rate of vision loss by about 50 percent and can improve visual acuity.
The eye is numbed before each injection and the doctor closely monitors each patient's condition following the injection. Although you may notice some loss of side vision—and it may slightly reduce your color and night vision—scatter laser treatment is needed to preserve your central vision.
A retina specialist can tell if you have any stage of diabetic retinopathy or macular edema.
Patients should routinely see their primary care provider who can determine the best form of blood sugar control for you. This is a non-invasive test, similar to an ultrasound, that helps detect fluid within the macula.
Although the flashing lights are often described as annoying, there is generally little to no discomfort associated with this procedure. This treatment is more effective before the fragile, new blood vessels have started to bleed which is why it is important to have regular, comprehensive dilated eye exams. Following the procedure, an eye patch is placed on the operated eye and you need to return to the office the next day.
Depending on the severity of your diabetic retinopathy, your doctor may suggest you have more frequent exams.
Other studies have found that controlling elevated blood pressure and cholesterol can reduce the risk of vision loss.
After the exam, your close-up vision may remain blurred for several hours due to the dilating drops. If you have macular edema in both eyes and require laser treatment, most often only one eye is treated at a time.
The Retina Group of Washington is involved in multiple national clinical trials evaluating the benefits of different medications in treating diabetic retinopathy. Even if bleeding has begun, scatter laser treatment may still be possible, based on the amount of bleeding. You need to be examined by your retina specialist at the first sign of blurred vision, before more bleeding occurs. If left untreated, proliferative retinopathy can cause severe vision loss and even blindness.
