Glaucoma is a disease of the optic nerve – the part of the eye that carries the images we see to the brain. The optic nerve is made up of many nerve fibers, like an electric cable containing numerous wires. When the pressure of the eye goes to high, damage to the optic nerve fibers occurs, and blind spots start to develop. These blind spots usually go undetected until the optic nerve is significantly damaged. Treatment for glaucoma usually involves daily eye drops, and may require lasers or surgery.
People with Diabetes can have an eye disease called diabetic retinopathy. This is when high blood sugar levels cause damage to blood vessels in the retina. These blood vessels can swell or leak. Or they can close stopping blood from passing through. Sometimes abnormal new blood vessels grow on the retina. The most important treatment is controlling blood sugars to avoid these serious complication in the eye. Treatment includes using lasers and special medications placed in the eye to prevent vision loss.
