What are the different types of diabetic retinopathy?

Diabetic retinopathy. An earlier stage of diabetic retinopathy is nonproliferative and is treated w glucose control/observation. A more severe form is proliferative or neovascular, requiring laser. There is also macular edema, requiring laser. Other treatments: avastin (bevacizumab).
See a retina special. Diabetes damages blood vessels in the retina causing bleeding and swelling (diabetic macular edema - dme): nonproliferative diabetic retinopathy. This is the most common kind and the kind that causes the most vision loss (from dme). When new abnormal blood vessels grow along the retina (proliferative), this can cause bleeding (vitreous hemorrhage), traction (retinal detachment), and/or glaucoma.
Bleeding. Diabetes affects the eyes in two ways. It causes leaking, bleeding blood vessels. It also causes blood vessels to die leading to the retina being starved for oxygen. Both of these can cause severe vision loss. Diabetics should be seen every year for a dilated eye exam. Treatment for both types or retinopathy is laser directed at different parts of the eye.

What are the early symptoms of type II diabetic retinopathy?

Possibly none. Diabetic eye changes depend on level of glucose control, age and duration of diagnosis. Many diabetics have no eye finding at all. Changes in focus from day to day can indicate high to low fluctuations in blood sugar. Non proliferatine dr may have no vision changes. Proliferative dr can have bleeding, leakage of fluid, fat(lipid)deposition in the retina. These changes can reduce vision permanently. Read more...
See below. Early diabetic retinopathy has no symptoms. By the time symptoms occur, the disease is advanced and vision loss may be permanent. It is for this reason that all diabetics should have a dilated examination every year. We are much better at preventing vision loss than restoring lost vision. Read more...

Are there different options for treating diabetic retinopathy?

Yes. Diabetes, especially when poorly controlled, can cause bood vessel pathology in the back of the eye (retinal). This leads to small and large bleeding areas, edema, and scarring which can lead to retinal detachment. Eyes with diabetic retinopathy are at risk for vision decrease or blindness. You should be seeing an ophthalmologic retinal specialist, not an optometrist. Read more...
Yes. The exact treatment should be under the direction of an ophthalmologist. Often laser treatments are used. Just as important is close conrtol of the diabetes under the direction of your doctor. Read more...
Laser or injections. Laser is most commonly used to treat the two main diabetic retina issues, swelling and new blood vessel growth. Sometimes surgery is required if the retinopathy gets to advanced and begins to damage the retina. There is lots of research surrounding the use of injected medications for swelling in the retina.

At what stage in diabetes type 1 does diabetic retinopathy occur?

10 years on average. A number of factors determine how quickly a person develops retinopathy with type 1 diabetes. The main determinant is how well they control their blood sugars. Blood pressure may also affect retinopathy. Lastly, different people may have identical blood sugar control and one will have retinopathy and the other won't, so there are also factors affecting susceptibility. Read more...

Does type 2 diabetes and diabetic retinopathy qualify you for a medical marijuana?

No. You must be from california. Mary jane (that'll date me) is used by many (perhaps 10 million regular users in america) for relaxation, pleasure, reducing stress and anxiety, nausea caused by chemotherapy, appetite enhancement in chronically ill people... Most 'prescriptions' written for medical marijuana are....Simply an unethical way of getting marijuana. Read more...
No way, dude! There is no medical indication for the use of marijuana in diabetic retinopathy nor type 2 diabetes - although i get this request a few times a week practicing in a state that has no legal medical marijuana. The effects of marijuana: increased appetite, mellow feeling, and slowing down are the opposite of what you need. You need to be dieting and exercising to lose weight. Read more...
