People.ith very high blood pressure and swelling of the optic nerve require emergency treatment in a hospital. The poorly nourished retina then sends out some type of chemical distress signal that causes new blood vessels to bud and grow proliferate on the retinal surface. This form of retinopathy is considered mild. Leitgeb A, et al. Even with proliferative retinopathy, the more dangerous form, people sometimes have no symptoms until it is too late to treat them. The same instruments used during vitrectomy also may be used to remove scar tissue or to repair a detached retina. Other eye problems that can occur in people with diabetes include: Cataract : cloudiness of the eye lens Glaucoma : increased pressure in the eye that can lead to blindness Macular enema: blurry vision due to fluid leaking into the area of the retina that provides sharp central vision Retinal detachment : scarring that may cause part of the retina to pull away from the back of your eyeball High blood sugar or rapid changes in blood sugar level often cause blurred vision. Patients will not have visual symptoms early on in the disease and need to be followed closely in case neovascularization occurs. Retinopathy is persistent or acute damage to the retina of the eye .
This fluid can resemble bubbles. The retina detects light and converts it to signals sent through the optic nerve to the brain. Diabetic retinopathy will occur in 65% of persons with type II diabetes within about 10 years of the beginning of diabetes. Both are biodegradable and release a sustained dose of corticosteroids to suppress DBE.
