Diabetic retinopathy |
Retinal effects of diabetes mellitus include microaneurusms, hemorrhage, dilation of retinal veins, and neovascularization (new blood vessels form in the retina.) Macular edema occurs as fluid leaks from the blood vessels into the retina and vision is blurred. Exudates (fluid leaking from the blood) appear in the retina as yellow-white spots. Laser photocoagulation is helpful in patients whom hemorrhaging on the retina has been severe. Also vitrectomy is done to resolve non resolving hemorrhages onto the vitreous jelly. Corticosteroids, which promote regression of abnormal blood vessels, are used to decrease fluid leakage and neovascularization. |
