Macular degeneration Stargardt's disease (juvenile macular degeneration, STGD) is an autosomal recessive retinal disorder characterized by a juvenile-onset macular dystrophy, alterations of the peripheral retina, and subretinal deposition of lipofuscin-like material.

Points to Remember Diabetic retinopathy is a disorder of major public health importance, and one of the major causes of visual loss which cannot be corrected with glasses . The condition is due to damage to the small blood vessels that nourish the retina, the light-sensitive tissue that lines the back of the eye. There are often no symptoms in the early stages of diabetic retinopathy. Therefore, vision may not be affected until the disease becomes severe. At this earliest stage, microaneurysms occur. Microaneurysms are small areas of balloon-like swelling in the retina's blood vessels. 2. As the disease progresses, some blood vessels that nourish the retina are blocked. Many more blood vessels are blocked, depriving several areas of the retina of blood supply.

Blindness and Vision Impairment Diabetic retinopathy is an eye disease that affects the tiny blood vessels in the retina of people with diabetes. Diabetes causes the small blood vessels in the retina to become weak and break down or become blocked. Diabetic retinopathy is the leading cause of blindness among working-age adults.

Retinal vessel occlusion A retinal vessel occlusion is a blockage in the blood vessels of your eye that can cause sight loss. There are two types of retinal blood vessels, arteries and veins, and either of these can be affected by an occlusion.therosclerosis is a problem with the condition of the inside of the blood vessel's wall. Blood vessels are like tubes with the blood flowing smoothly through them. Atherosclerosis is a problem with the inside of the tube. The tube is usually wide and smooth so that the blood flows directly through it.

Stargardt's Disease (Fundus Flavimaculatus) Central vision loss also occurs, while peripheral vision usually is retained. Stargardt's disease is diagnosed by the presence of small, yellowish spots of deteriorating tissue (drusen) sloughed off from the colored or outer covering of the retina (retinal pigment epithelium).Progressive vision loss eventually leads to blindness in most cases.entral vision loss also occurs, while peripheral vision usually is retained. Stargardt's disease is diagnosed by the presence of small, yellowish spots of deteriorating tissue (drusen) sloughed off from the colored or outer covering of the retina (retinal pigment epithelium).

Vascular Tumors of the Retina and Choroid: Diagnosis and Treatment While the vascular tumors of the retina and choroid are classified as benign, visual symptoms secondary to exudative retinal detachment as well as a variety of other mechanisms are common and are a major source of long-term visual disability. Treatment can often be challenging.

Retinitis Pigmentosa Retinitis pigmentosa is the most common of a group of hereditary progressive retinal degenerations or dystrophies. There is considerable variation and overlap among the various forms of retinitis pigmentosa. Common to all of them is progressive degeneration of the retina, specifically of the light receptors, known as the rods and cones.

Evaluation and Management of Suspected Retinal Detachment Retinal detachment often is a preventable cause of vision loss. There are three types of retinal detachments: exudative, tractional, and rhegmatogenous. The most common type is rhegmatogenous, which results from retinal breaks caused by vitreoretinal traction.Risk factors for retinal detachment include advancing age, previous cataract surgery, myopia, and trauma.he second type of detachment, tractional retinal detachment, occurs via centripetal mechanical forces on the retina, usually mediated by fibrotic tissue resulting from previous hemorrhage, injury, surgery, infection, or inflammation.

- Arteriosclerotic retinopathy: Retinal disease caused by arteriosclerosis. In this condition, the arterioles (small arteries) in the retina become partially blocked because of thickening of their walls.Using an ophthalmoscope, a doctor can see the thickened arterioles and other indications of diminished blood supply to the retina.n this condition, the arterioles (small arteries) in the retina become partially blocked because of thickening of their walls.

- This condition generally produces vision problems and in some cases, it may result in substantial vision loss. There are a range of possible causes of retinal inflammatory disease, including an autoimmune disorder, infection in the eye, tumor in or near the eye, trauma to the eye and exposure to certain toxins.owever, for some patients a cause cannot be determined. The symptoms of retinal inflammatory disease vary from patient to patient but may include: 1  Blurry vision. 2  Floaters in the eye. 3  Eye pain.

Macular degeneration Age-related macular degeneration begins with characteristic yellow deposits (drusen) in the macula, between the retinal pigment epithelium and the underlying choroid. Most people with these early changes (referred to as age-related maculopathy) still have good vision.

Overview Dry macular degeneration usually affects both eyes. If only one eye is affected, you may not notice any changes in your vision because your good eye may compensate for the weak eye. And the condition doesn't affect side (peripheral) vision, so it rarely causes total blindness. Dry macular degeneration is one of two types of age-related macular degeneration. It can progress to wet (neovascular) macular degeneration, which is characterized by blood vessels that grow under the retina and leak. The dry type is more common, but it usually progresses slowly (over years).
