Is macular degeneration genetic?

Some. There are a few inherited forms especially those in the young and those associated with drusen deposits that have strong inheritance. Less certain is the inheritance pattern of ordinary, older age macular degeneration - the data is still being worked out. You can help protect your macula with a good diet, avoidance of sunlight and stopping smoking.
Yes. Certain genetic variations (such as in the complement factor system) that are inherited put you at increased risk for macular degeneration.
Yes. The lifetime risk of developing late-stage macular degeneration is 50% for people that have a relative with macular degeneration, versus 12% for people that do not have relatives with macular degeneration, a fourfold higher risk.

Is macular degeneration a genetic problem?

Maybe. More evidence is available that there is a strong genetic component to disease development. Equally as important are environmental risk factors which interact with the genetic susceptibility like smoking. Read more...

Yes. There is an important genetic aspect involved in the development of amd. Read more...

My dad has macular degeneration and so do i. Is this genetic? Could my children have it?

Could be. There is no question that genetics can play a role in the development of amd. It is multifactorial though and just because you have a strong family history doesn't necessarily mean you will pass it down. But your kids will need to be closely followed when they're older. Read more...
Which kind? There are multiple types of md. Many are hereditary, i see age related macular degeneration every day in my practice. What we know about it: many genes on many chromosomes involved - genetic component, but also environmental or epigenetic factors including antioxidant levels. So for amd, there appears to be a genetic component, in addition to other factors. Read more...

What is symptom of macular degeneration?

Varries. I have seen patients with many different symptoms (first sign) of macular degeneration. The most common is decreased ability to read (or need more light to read) or difficulty adapting to sudden changes in the lighting in the environment; light to dark or dark to light situations.

Decreased vision. Both the wet and dry forms of armd cause decrease in central vision. Distortion is often an early symptom and an amsler grid is a good self screening tool. Vision loss from the dry form is usually slowly progressive and lessor in degree than the wet form which can have very dramatic decrease in vision that is rapid and significant. Read more...

What are the symptoms of macular degeneration?

Decreased vision. Symptoms of macular degeneration may include: decreased central vision, distortion of straight lines, poor light tolerance and dark adaptation and in very severe cases visual hallucinations. Read more...

Many. Age related macular degeneration (amd) is a leading cause of visual loss in the elderly population. Treatment depends on type and severity of amd. The symptoms are highly variable also: mild to moderate blurring in central areas of vision, distortion of images, haziness. Sometimes, in early stages, pt do not yet have symptoms. In late stages, visual hallucinations are possible. Read more...
Metamorphopsia . The majority of people affected by AMD are asymptotic and don't have any visual deficit. However, blurred vision and more specifically distortion can occur. For instance, straight lines spear crooked - metamorphopsia. Read more...

What is the first symptom of macular degeneration?

Vision changes. The first symptom most people experience with macular degeneration is a change in vision. An amsler grid is a simple screening tool available for home use that can allow patients who are at risk for macular degeneration to monitor for such changes. Read more...
See below. Usually central distortion in the vision of one (sometimes both) eye(s). Straight lines may appear wavy (metamorphopsia). Read more...

What are the different kinds of macular degeneration?

Wet and Dry. There are two general forms: dry about 85% which is the slow breakdown of macular pigment and vision decrease. The wet form has a more rapid progression with formation of new blood vessels, severe vision loss and occasionally intraocular hemorrhage. There are new medications which can address this.

Dry, wet. Dry = drusen build up in the macula that can eventually distort vision, and also lead to atrophy wet = growth of abnormal blood vessels from the choroid into the retina like weeds growth through cracks in a sidewalk dry is more common, wet has the new injection therapies also can have polypoidal lesions in wet amd. Read more...
Kinds of AMD. There are the two major categories of wet and dry macular degeneration. There are the four stages or grades of severity for dry amd. There are also two variants of amd called retinal angiomatous proliferation (RAP) and polypoidal choroidal vasculopathy (pcv). Of the wet types, there is classical and there is occult. More terms exist to describe features in wet amd as well. Read more...

Is it rare for teenagers to have macular degeneration?

Very rare. The common type of macular degeneration is called amd, standing for "age-related macular degeneration", and the age is old age, usually over 60. However, there are rarer conditions of the retina that can lead to degeneration. Stargardt's disease, retinitis pigmentosa, pattern dystrophies of the retinal pigment epithelium, retinal cone dystrophies, and familial drusen can affect teens. Read more...

How should you verify a diagnosis of macular degeneration?

See ophthalmologist. Although that would be uncommon at your age of 48, an ophthalmologist can look in the back of your eye to determine if you have this condition. There is an uncommon inherited form which starts more commonly at a younger age but the eye doctor can recognize this also for you. Read more...
Eye Exam. You need a complete eye exam to diagnose macular degeneration. You should see your ophthalmologist. Read more...

What happens to the vision if a person has macular degeneration?

Central vision loss. At it's most extreme, macular degeneration causes the central macula, or the most acute vision center of the eye, to be damaged. The vision loss can be severe, but usually the peripheral vision is spared and can be used to get around. Read more...
Varies. Sometimes the vision is not affected, sometimes the vision gets distorted (wavy, crooked, broken lines, or dark spots on amsler grid), and sometimes severe central vision loss can occur. Depends on the degree of the disease and complications from it. Read more...
Fairly common. Macular degeneration was the most common cause of legal blindness in individuals over 50. With modern treatment strategies, severe vision loss is much less common. Some degree of vision impairment usually develops with this chronic degenerative disease over time. The earliest symptoms include delay in adjusting to dim light ; needing more light to read. Visual acuity decline follows. Read more...
