Is Macular Degeneration Caused By Trauma
Unknown: The cause (trigger) for this condition, which is age related, is unknown. We know the effects, have some treatments available, and there is really extensive research in the cause but no positive results so far. A few are inherited but most have no obvious inheritance pattern. This is treated by retinal specialists who should be consulted if you are having problems.
Aging: There is still no clear single cause for Age-related Macular Degeneration (AMD). It is a disease of geriatric. The incident is highest among those over 70. Genetic may play a role. Smoking has been shown to increase the risk of progression of the disease. Other conditions have also been cited such as cardiovascular disease.
Genetics and age: Macular degeneration is a condition of the aging eye. Most people would get macular degeneration if they lived to be 150 years of age. The macula deteriorates with age and develops / deteriorates sooner in some families than others. Associated factors that can speed the development of macular degeneration are high blood pressure, high cholesterol, smoking, uv sunlight exposure.See 2 more doctor answers
AMD: There are multiple causes of macular degeneration and are usually age and history dependent. Most commonly in those over 55 is age-related macular degeneration. In younger patients, there may be hereditary causes. Trauma, infection and inflammation may also cause various forms of macular degeneration as well.See 1 more doctor answer
Juvenile cataracts: Congenital cataract: during pregnancy, mom has infection (ie measles/rubella (the most common cause), rubeola, chicken pox, cytomegalovirus, herpes simplex, herpes zoster, poliomyelitis, influenza, Epstein-Barr virus, syphilis, toxoplasmosis. Juvenile: include, prior trauma, infection, inflammation, JRA. Macular degener: gene mutation-> Stargardt's disease, Best disease, and juvenile retinoschisis
Genetics: The predisposition for macular degeneration is inherited. It is a very complex disease with several, if not many genetic mutations contributing to risk. Additionally, there are other health factors that modulate disease risk. Most importantly nutrition, but also life style (smoking=bad), etc. Rule of thumb: if something is thought to be good for the heart, it probably also reduces amd risk.See 1 more doctor answer
Number of factors: Macular degeneration (amd) is primarily an age-related disease (age 50+), but there are genetic and environmental factors that contribute to age of onset and severity. Risk factors for cardiovascular disease (stroke, heart attack) are also risk factors for amd. Smoking is the top modifiable risk factor. Of course, there is a lot we still don't understand about amd.See 1 more doctor answer
Macular degeneration: Is when the layer of cells of the back of the retina do not function well, leaving deposits called drusen mostly in the central vision area, the macula. This is caused by the age ing process, things that can damage the retina cells, ie uv light, and can be related to nutritional deficiencies. This entity is called age related macular degeneration (amd). Risk factors include old age, family histor.
A disease: Macular degeneration is a degenerative disease that affects the rods and cones (photoreceptors) in the retina. The degeneration and death of these is multifactorial. Changes in nutrition, blood flow, heredity, ultraviolet exposure all increase your risks for the disease. Best defense: UV protection, good diet high in green leafy vegetables, multivitamin with lutein-- and don't get a day older.
Are there any conditions other than macular degeneration that cause lines to look wavy in your vision?
Can dry macular degeneration turn into the wet form? I've read that it sometimes happens, but it doesn't make sense to me. Don't the two forms of macular degeneration have different causes? .
Macular degeneration: Nearly everyone who has wet amd initially had the dry form. There is definitely a progression from the dry type to the wet type. This is why high dose antioxidant vitamins and zinc is recommended for people with high risk dry amd - your eye md will be able to tell with a dilated retinal exam. As we learn more about the genetics of amd it is clear that there may be subtypes with different causes.See 3 more doctor answers
Which form of macular degeneration is more serious? L was recently diagnosed with the dry form of macular degeneration. Is this form more or less likely to cause vision loss or other problems than the wet form? .
This: This is actually an interesting question. The answer is that both forms cause vision loss. Dry mac degen causes a slow progression, so this is better in some ways. On the other hand, there is no treatment for the dry form, so the end result may be very severe loss of vision. Wet md causes a more sudden loss of vision due to bleeding or swelling. There is treatment, in the form of injected medications, that can halt the progression, and in 50% of patients may actually cause some improvement!See 3 more doctor answers
ARMD Floaters?: Floaters are of two primary types--lets call them "fixed" or stationary floaters (also called scotomas) and "mobile" floaters. ARMD usually causes fixed floaters, not mobile floaters, and does so by damaging part of the retina to produce a blind spot or multiple blind spots by distorting the surface of the retina and damaging it. You are probably much too young for ARMD but discuss with eye doc.
Retinal breakdown: Scarring the in the maculae can occur in both the wet and dry forms of macular degeneration. Usually, it is problematic in the wet form when there is leakage of serum or blood from new blood vessels that cause inflammation and retinal scarring - here the prognosis is guarded. In advanced forms of dry macular degeneration there can be scarring as well.See 2 more doctor answers
Highly variable.: Most patients with macular degeneration have the dry type and suffer mild decrease in vision. However, macular degeneration is likely to cause significant vision loss if wet. If diagnosed and treated in early stages, most cases will have fair prognosis, even if wet. However, some cases may cause immediate loss of vision by a hemorrhage, while others may take years to progress to blindness.See 1 more doctor answer
