1. Complete Information on Coats disease June 18, 2008 Coats’ disease also known as exudative retinitis. Coats’ diseas is a rare eye disorder, causing full or partial blindness, characterized by abnormal development of blood vessels behind the retina. It is a progressive condition of the retinal capillaries which occurs in children and young adults, usually males. Retinal capillaries play an important part in the nourishment of the retina which forms the thin light-sensitive screen lining the inside of the back two thirds of the eye. Light reaching the retina is converted into electrical impulses which pass along the optic nerve to the brain where... (read more) Author: Juliet Cohen

2. Complete Information on Central serous chorioretinopathy June 18, 2008 Central serous chorioretinopathy too known as Central serous retinopathy (CSR. Central serous chorioretinopathy is a retinal disorder which affects the macula. It is an “idiopathic disorder” which means that the exact reason is unidentified. Central serous is associated with an altitude of the macula payable to leak of fluid from the circulation behind it. The leak occurs through a flaw in the tissue bed known as the retinal pigment epithelium. The retinal pigment epithelium is an unmarried celled bed that lies between the retina and the choroid. This tissue bed usually serves to forbid fluid ... (read more) Author: Juliet Cohen

3. Health Benefits of Vitamin A June 02, 2008 Consumers think of Vitamin A as one type of vitamin which it is, but it belongs to a group of related nutrients all classified as A; however working in two totally different ways.

5. Improve Your Vision Clarity and Acuity with Cataract Surgery May 19, 2008 When the light rays focus well on the retinal surface, we see clearly. When they focus a little in front of the retina, or behind it, we notice blurriness. The lens is flexible and in normal, clear vision, tiny muscles change the convexity/concavity of its shape to allow us to focus well at all distances. The lens is composed of water and protein arranged so as to keep it very translucent, allowing the light to pass through to the retina unimpeded. As We Age The lens gradually changes as we age. The arrangement of protein and water changes so that some of the protein clumps together... (read more) Author: Patricia Woloch

6. Complete Information on Bardet-Biedl syndrome 1 May 13, 2008 Bardet-Biedl syndrome is a genetic disorder. Bardet-Biedl syndrome is a complex disorder that affects many parts of the body including the retina. This syndrome have a retinal degeneration similar to retinitis pigmentosa (RP). Eight genes (BBS1 to BBS8) that are responsible for the disease when mutated have been cloned, and most of the gene products encoded by these BBS genes are located in the basal body and cilia of the cell. It has been postulated that these BBS gene products might involve in the cell signaling pathway in the cilia, and these signaling systems play an essential role in the ...

7. Information on retinal detachment-a serious retinal disease May 05, 2008 What is retina? The retina is the light-sensitive layer of tissue that lines the inside of the eye and sends visual messages through the optic nerve to the brain. When the retina detaches, it is lifted or pulled from its normal position. If not promptly treated, retinal detachment can cause permanent vision loss. The retina is about the size of a postage stamp. It consists of a central area called the macula and a much larger peripheral retina. The light receptor cells within the retina are of two types, called the rods and the cones. Rods allow us to see in reduced illumination. Cones pro... (read more) Author: Peter Hutch

20. Confusing Retinal Migraine August 14, 2007 Due to the varied types of the disease, most doctors would diagnose migraine based on the universally accepted standards of The International Classification of Headache Disorders (ICHD) to avoid misdiagnosis. Retinal migraine is a classic example of confusion and misdiagnosis, simply because the term is often poorly understood and widely misused. When a migraine sufferer is given a diagnosis that lacks accuracy in diagnostic terms but is given more of a descriptive term, a problem may arise. When these descriptive terms are used frequently, they miss out on its real diagnosis. The Internation... (read more) Author: malo alvarez

25. Dry Macular Degeneration March 29, 2006 There are two types of Macular Degeneration or AMD. The first and more common type is the Dry Macular Degeneration. 85% to 90% of the cases of AMD or Age-related macular degeneration are of the dry or atrophic type. It is also a fact that most cases of age-related macular degeneration always starts out as the dry form. Dry macular degeneration occurs when the RPE or retinal pigment epithelium cells begin to atrophy (deteriorate) and lose their pigment. This deterioration is associated with the formation of small yellow deposits under the macula, known as Drusen. This leads to the contraction a... (read more) Author: Kevin Stith
