Diabetic blindness "big three" killers

Diabetic eye disease throughout the various stages of diabetes is the most important complication of diabetes. Among them, neovascular glaucoma, sudden blindness cataract, retinal detachment is the most serious threat of diabetes complications, it was named as diabetes, blindness, "the three killers."

Neovascular glaucoma

Blinding glaucoma accounted for 20% of the total number of blind people. Many different kinds of glaucoma, the most refractory to devaluation of neovascular glaucoma, its ferocious, pain often lose, and the cure rate is very low. Diabetes, glaucoma neovascular glaucoma is more often seen in advanced diabetic retinopathy, retinal ischemia and neovascularization of a change in the iris, and then induced neovascular glaucoma.

As the rapid development of neovascular glaucoma, visual acuity declined sharply, may be associated with eye pain, migraine headaches, nausea, vomiting, severe cases can result in heavy bleeding eye, drug treatment and more difficult to work. Surgical treatment is often a result of new filtration mouth again after adhesion, resulting in closure of surgical failure.

Sudden blindness cataract

Cataract caused by diabetes is called diabetic cataract or complicated cataract, diabetic eye disease complicated by the second largest, is an important factor for diabetic blindness; its occurrence and high blood sugar, aqueous osmotic pressure changes and metabolic disorders the toxicity of the product concerned. Cataract caused by high blood sugar, also known as True diabetic cataract. In the latter stage of diabetes as uveitis, diabetic retinopathy severe metabolic disorder caused by the lens of self-induced cataract, also known as complicated cataract.

True diabetic cataract occurs mainly in young patients with severe diabetes, may also occur in young children, while relatively rare in the elderly. Eyes more than the same time the disease progress faster, and often a few days to be harvested.

If the onset of diabetic cataract early control of blood glucose in time, become turbid and transparent lens can be partially restored. Once the cloudy lens just rely on surgery to restore their sight completely. If not treated quickly can be blinding, so called sudden blindness cataract. The disease can be prevented, control of blood glucose, regular inspection, early treatment, eye complications can be avoided to the "dark."

Retinal detachment

Diabetic retinopathy is the end of retinal detachment. Diabetic retinopathy can be divided into six phases, with duration of diabetes and the changing condition, diabetic retinopathy is gradually increased, blood glucose is a catalyst for the development of diabetic retinopathy.

When the localized retinal detachment, within the same area had a blind spot - visual field defect. Once the retina detachment will lead to blind.

Diabetic retinopathy caused by retinal detachment require surgery. Early surgical treatment is to restore visual function in the premise, the early small retinal detachment surgery can save part of the visual function, a wide range of retinal detachment with poor prognosis.
