Age-related macular degeneration

Age-related macular degeneration is an eye disease that is a leading cause of vision loss in older people in developed countries. The vision loss usually becomes noticeable in a person's sixties or seventies and tends to worsen over time.Age-related macular degeneration mainly affects central vision, which is needed for detailed tasks such as reading, driving, and recognizing faces. The vision loss in this condition results from a gradual deterioration of light-sensing cells in the tissue at the back of the eye that detects light and color (the retina). Specifically, age-related macular degeneration affects a small area near the center of the retina, called the macula, which is responsible for central vision. Side (peripheral) vision and night vision are generally not affected.Researchers have described two major types of age-related macular degeneration, known as the dry form and the wet form. The dry form is much more common, accounting for 85 to 90 percent of all cases of age-related macular degeneration. It is characterized by a buildup of yellowish deposits called drusen beneath the retina and slowly progressive vision loss. The condition typically affects vision in both eyes, although vision loss often occurs in one eye before the other.The wet form of age-related macular degeneration is associated with severe vision loss that can worsen rapidly. This form of the condition is characterized by the growth of abnormal, fragile blood vessels underneath the macula. These vessels leak blood and fluid, which damages the macula and makes central vision appear blurry and distorted.

Macular degeneration

Macular degeneration, or age-related macular degeneration (AMD), is a leading cause of vision loss in Americans 60 and older. It is a disease that destroys your sharp, central vision. You need central vision to see objects clearly and to do tasks such as reading and driving. . AMD affects the macula, the part of the eye that allows you to see fine detail. It does not hurt, but it causes cells in the macula to die. There are two types: wet and dry. Wet AMD happens when abnormal blood vessels grow under the macula. These new blood vessels often leak blood and fluid. Wet AMD damages the macula quickly. Blurred vision is a common early symptom. Dry AMD happens when the light-sensitive cells in the macula slowly break down. Your gradually lose your central vision. A common early symptom is that straight lines appear crooked. Regular comprehensive eye exams can detect macular degeneration before the disease causes vision loss. Treatment can slow vision loss. It does not restore vision.

Age-related macular degeneration 1

Age-related macular degeneration (ARMD) is a progressive degeneration of photoreceptors and underlying retinal pigment epithelium (RPE) cells in the macula region of the retina. It is a highly prevalent disease and a major cause of blindness in the Western world. Drusen, pale excrescences of variable size, and other deposits accumulate below the RPE on the Bruch membrane; clinical and histopathologic investigations have shown that these extracellular deposits are the hallmark of early ARMD. As ARMD advances, areas of geographic atrophy of the RPE can cause visual loss, or choroidal neovascularization can occur to cause wet, or exudative, ARMD with accompanying central visual loss (summary by De et al., 2007). Genetic Heterogeneity of Age-Related Macular Degeneration ARMD2 (153800) is associated with mutation in the ABCR gene (601691) on chromosome 1p, and ARMD3 (608895) is caused by mutation in the FBLN5 gene (604580) on chromosome 14q31. Up to 50% of the attributable risk of age-related macular degeneration (ARMD4; 610698) appears to be explained by a polymorphism in the CFH gene (134370.0008). ARMD5 (613761) and ARMD6 (613757) are associated with mutation in the ERCC6 (609413) and RAX2 (610362) genes, respectively. ARMD7 (610149) and ARMD8 (613778), which both represent susceptibility linked to chromosome 10q26, are associated with single-nucleotide polymorphisms in the HTRA1 (602194) and ARMS2 (611313) genes, respectively. ARMD9 (611378) is associated with single-nucleotide polymorphisms in the C3 gene (120700). ARMD10 (611488) maps to chromosome 9q32 and may be associated with a polymorphism in the TLR4 gene (603030). ARMD11 (611953) is association with variation in the CST3 gene (604312); ARMD12 (613784) with variation in the CX3CR1 gene (601470); and ARMD13 (615439) with variation in the CFI gene (217030). ARMD14 (615489) is associated with variation in or near the C2 (613927) and CFB (138470) genes on chromosome 6p21. ARMD15 (615591) is associated with variation in the C9 gene (120940). There is evidence for a form of ARMD caused by mutation in the mitochondrial gene MTTL1 (590050). A haplotype carrying deletion of the complement factor H-related genes CFHR1 (134371) and CFHR3 (605336) is also associated with reduced risk of ARMD. Lotery and Trump (2007) reviewed the molecular biology of age-related macular degeneration and tabulated the genes associated with ARMD, including those with only positive findings versus genes for which conflicting results have been found. [from OMIM]

Retinopathy

The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. In the center of this nerve tissue is the macula. It provides the sharp, central vision needed for reading, driving and seeing fine detail. Retinal disorders affect this vital tissue. They can affect your vision, and some can be serious enough to cause blindness. Examples are. -Macular degeneration - a disease that destroys your sharp, central vision. -Diabetic eye disease. -Retinal detachment - a medical emergency, when the retina is pulled away from the back of the eye. -Retinoblastoma - cancer of the retina. It is most common in young children. -Macular pucker - scar tissue on the macula. -Macular hole - a small break in the macula that usually happens to people over 60. -Floaters - cobwebs or specks in your field of vision.

Glycogen storage disease, type II

Glycogen storage disease type II (GSD II), or Pompe disease, is classified by age of onset, organ involvement, severity, and rate of progression. Classic infantile-onset Pompe disease may be apparent in utero but more often presents in the first two months of life with hypotonia, generalized muscle weakness, cardiomegaly and hypertrophic cardiomyopathy, feeding difficulties, failure to thrive, respiratory distress, and hearing loss. Without treatment by enzyme replacement therapy (ERT), classic infantile-onset Pompe disease commonly results in death in the first year of life from progressive left ventricular outflow obstruction. The non-classic variant of infantile-onset Pompe disease usually presents within the first year of life with motor delays and/or slowly progressive muscle weakness, typically resulting in death from ventilatory failure in early childhood. Cardiomegaly can be seen, but heart disease is not a major source of morbidity. Late-onset (i.e., childhood, juvenile, and adult-onset) Pompe disease is characterized by proximal muscle weakness and respiratory insufficiency; clinically significant cardiac involvement is uncommon in the late-onset form. [from GeneReviews]
