Diabetic retinopathy causes various changes in the eyes and thus could lead to different eye conditions. This disease can cause the blood vessels in the retina to leak which leads to swelling in the macula. The macula is part of the retina and is responsible for central vision. This inflammation is called diabetic macular edema and can cause blurry central vision. Another condition which can result from diabetic retinopathy is called neovascular glaucoma. This occurs when fragile harmful blood vessels begin to form due to diabetic retinopathy. These abnormal blood vessels prevent fluid from properly draining out of the eye, thus increasing the eye pressure and leading to this type of glaucoma. The damage from diabetic retinopathy can cause scars in the back of the eye. These scars can pull on the retina, separating it from the back of the eye. This is called retinal detachment. Diabetic retinopathy can cause different kinds of changes in your eyes and therefore it's extremely important to be monitored by an eye doctor to prevent any further damage.
