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. ...Read more
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. ...Read more
Multifactorial: Macular degeneration describes a lot of conditions potentially. Some are single gene genetic disorders such as stargardt macular dystrophy. The most common cause is age-related macular degeneration. The condition has a strong genetic association (many genes involved). Other factors such as age, smoking, diet and other health factors contribute to its causation. ...Read more
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. ...Read more
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 ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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! ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
May speed cataracts: This type of medication may sometimes speed up cataract formation (clouding of the lens inside the eye). Fortunately, if vision is significantly affected, outpatient corrective surgery can generally resolve & improve the situation. Visit your eye MD while on such meds! ...Read more
Macular degeneration: The usual risk factors are positive family history, cigarette smoking, far sightedness, light iris color, high blood pressure, high cholesterol, female gender, heart disease, and of course aging. To my knowledge alcoholism in a parent doesn't cause macular degeneration in their children, unless the above risk factors apply to the children. ...Read more
How fast does macular degeneration cause vision loss? My doctor would only say it happens slowly, but didn't really define “slow.” is it a couple of years, 10 years, more? I understand each person is different, but what's average? .
Over many years: Macular degeneration is a slowly progressive condition. In the absence of "wei" disease, vision changes start as delayed recovery of vision from bright light, then needing more and moe light to see/read, and eventually progressive decline in visual acuity. For poor vision to develop from the earliest signs is usually decades. At any time, a patient can develop wet disease, needing treatment. ...Read more
I just read an article that says too much tv watching or computer staring would cause an epidemic of blindness or macular degeneration. True or No?

Hi simple question (I thinnk) what can cause being unable to focus even with new prescription glasses (hae start of: cataracts, macular degeneration?
Focus problem: May depend on age. Around 40 or so the lens is large and hard to bend so seeing up close is difficult. That's why people use readers, or have 'adds' to their prescription as in bifocals or trifocals. Other causes include cataract, corneal opacities, macular issues, vascular issues, optic nerve problems and on and on. See an ophthalmologist to get a firm diagnosis. ...Read more
I just read an article that says that watching tv or staring at computers will cause an epidemic of blindness or maybe macular degeneration. True or no?
It is not true, however, sitting for long periods of time is not good for your health.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more
What causes light flashes in the eye after laser surgery? What causes light flashes in the eye after laser surgery for glucoma and macular degeneration of the eye?
After images.: Light flashes in the eye after laser surgery are most likely after images. Usually they go away. Laser is used for glaucoma, diabetes, and retinal tears. It is less often used these days in macular degeneration. Light flashes can also be caused by retinal traction and impending retinal tear. A good thorough retinal exam will eliminate most causes for concern. ...Read more
To some degree:
Macular degeneration is a wide spectrum of conditions where the tissue in the back of the eye changes with time. In most types where there is primarily gradual loss of function there is no real cure currently.
In the "wet" types there is growth of scar tissue. These types may be helped significantly with injections of a variety of drugs into the eye to suppress the growth of the scar tissue. ...Read more
Stages of mac degen: The areds severity scale has been used to classify dry macular degeneration. Wet macular degeneration does not have such linear demarcations. It is categorized into classical cnv and occult cnv. There are several subtypes of occult. There are two variants of amd, (retinal angiomatous proliferation) RAP and pcv (polypoidal choroidal vasculopathy). Findings associated with wet amd are critical. ...Read more
Yes: But not classic age related macular degeneration. There are a few inherited maculopathies which are forms of macular degeneration which might show up in the teen through 30's age range. These can be quite profound and handicapping but fortunately rare. If you have suspicion about this, you should see your ophthalmologist without delay. ...Read more
