Proliferative diabetic retinopathy (PDR) is the more advanced form of the disease. At this stage, new fragile blood vessels can begin to grow in the retina and into the vitreous, the gel-like fluid that fills the back of the eye.
Tuberculosis (TB) is a disease caused by bacteria that are spread from person to person through the air. TB usually affects the lungs, but it can also affect other parts of the body, such as the brain, the kidneys, or the spine.  Proliferative diabetic retinopathy (PDR) is the more advanced form of the disease. At this stage, new fragile blood vessels can begin to grow in the retina and into the vitreous, the gel-like fluid that fills the back of the eye. Diabetic retinopathy is the result of damage caused by diabetes to the small blood vessels located in the retina. Blood vessels damaged from diabetic retinopathy can cause vision loss: 1  Fluid can leak into the macula, the area of the retina which is responsible for clear central vision. Diabetic eye disease can affect many parts of the eye, including the retina, macula, lens and the optic nerve. Diabetic eye disease is a group of eye conditions that can affect people with diabetes. 1  Diabetic retinopathy affects blood vessels in the light-sensitive tissue called the retina that lines the back of the eye. 2  Diabetic macular edema (DME). Diabetic eye disease also includes cataract and glaucoma: 1  Cataract is a clouding of the eye’s lens. 2  Glaucoma is a group of diseases that damage the eye’s optic nerve—the bundle of nerve fibers that connects the eye to the brain. Pulmonary hypertension is a hemodynamic state defined by a resting mean pulmonary artery pressure at or above 25 mm Hg. Because this definition is based on hemodynamic criteria, pulmonary hypertension can be the result of a variety of diseases of different causes. Pulmonary arterial hypertension (PAH), however, should be distinctly differentiated from pulmonary venous hypertension resulting from left heart disease. Physicians' Desk Reference: A thick volume that provides a guide to prescription drugs available in the United States. Although not exactly recommended fare for bedtime reading, the PDR is the most commonly used drug reference. The information is the same as the leaflet in the drug package, also known as the package insert. Drug companies pay to have their drug included, so many generic medicines will not be in the book. 4 1 Approaches to Creating Definitions of MDR, XDR, PDR 2 In a joint initiative by the European Centre for Disease Prevention and Control (ECDC) and 3 the Centers for Disease Control and Prevention (CDC), a first meeting of experts was held in 4 Stockholm in January 2008.  Diabetic retinopathy is a condition occurring in persons with diabetes, which causes progressive damage to the retina, the light sensitive lining at the back of the eye. It is a serious sight-threatening complication of diabetes. Diabetic retinopathy is the result of damage caused by diabetes to the small blood vessels located in the retina. Blood vessels damaged from diabetic retinopathy can cause vision loss: 1  Fluid can leak into the macula, the area of the retina which is responsible for clear central vision. Table 6.

Table 5. 1 Proliferative diabetic retinopathy (PDR) is the more advanced form of the disease. 2  At this stage, circulation problems cause the retina to become oxygen deprived. 3  As a result new fragile blood vessels can begin to grow in the retina and into the vitreous, the gel-like fluid that fills the back of the eye. Diabetic retinopathy is the result of damage caused by diabetes to the small blood vessels located in the retina. Blood vessels damaged from diabetic retinopathy can cause vision loss: 1  Fluid can leak into the macula, the area of the retina which is responsible for clear central vision.
