God knows: A lot of research being done now. Seems to be a problem with metabolizing the rods and cones which leads to drusen, which affects the barrier to the vascular layer. Many theories out there.
Dr. Peter Francis

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.
Dr. Michael Ham

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.
Dr. Richard Bensinger
Ophthalmology 53 years experience
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.

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.

Could macular degeneration cause dizziness?

Not usually: Macular degeneration in its advanced state can cause blurring of vision. If the blur is isolated to only one eye, a loss of depth perception could theoretically cause a dizzy sensation.
