Treatment of neovascular age-related macular degeneration in patients with diabetes
Macular degeneration is the leading cause of vision loss among Type 2 diabetes increases the risk of developing macular degeneration. The Association Between Diabetes and Age-Related Macular Degeneration Among the Elderly in Taiwan. He MS(1)(2), Chang FL(1), Lin HZ(1). Breakdown of the light-sensitive cells in the macula, the central part of the retina responsible for sharp, central vision. Age-related macular.
Does having type 2 diabetes have anything to do with having macular degeneration?
In this form, new blood vessels begin to form behind the retina and grow into the macula. The new vessels, which are very fragile, burst easily, leaking blood and fluid under the macula and causing rapid damage and central vision loss.

Learn about preventive steps and treatments for diabetic retinopathy from retinal specialist Dr. As more light-sensitive cells are destroyed, people with dry AMD develop a blind spot in the center of their field of vision that expands as the disease progresses. For people with wet AMD, straight lines may begin to appear wavy. This is because leaking fluids raise the macula from its normal position on the back of the eye. People with wet AMD may also develop a blind spot in the middle of their visual field.
Macular Degeneration - Diabetes Self-Management
Sometimes the person is asked to view an Amsler grid, a chart with a graphlike pattern of lines and a black dot at the center. For people with central vision changes from AMD, the lines on the grid will appear warped, and some lines may be missing.
If the doctor suspects wet AMD, he may administer a test called fluorescein angiography, in which a dye injected into the arm travels to the retina, enabling the doctor to photograph and examine leaking blood vessels. Logistic regression was used to examine the association between diabetes mellitus and early AMD.
After adjusting for age, sex, current smoking, obesity, and hypertension, significant association was found between diabetes mellitus and early AMD. Subjects with diabetes mellitus were more likely to have early AMD odds ratio, 1.
The underlying biological processes remain to be determined. In the population 50 years and older, age-related macular degeneration AMD is the primary cause of visual impairment in developed countries, and it is the third leading cause of visual impairment worldwide. Knowledge about modifiable cardiovascular risk factors related to AMD, including cigarette smoking, 67 obesity, 8 lipid levels, 9 and hypertension, 1011 has increased considerably.
However, although diabetes mellitus as a major risk factor for cardiovascular disease may be linked with AMD, data from most epidemiologic studies have not been consistent on this point.
Some studies have shown an association, 12 - 15 while others have not.New Breakthrough For Sufferers Of Diabetic Macular Edema Will Save Sight
It is safer than laser therapy and may be able to preserve central vision. This treatment combines a cold laser with a medicine called verteporfin.
The medicine is injected into the bloodstream and ends up in the macula. The cold laser causes a reaction when combined with medicine that closes the abnormal blood vessels stopping the leak.

A surgeon surgically detaches the retina and moves the fovea in order to expose the abnormal cells. The surgeon then removes the cells or uses a hot laser to destroy them without risking the fovea. This treatment prevents further vision loss and in rare instances improves vision.
