What is the difference between macular dystrophy vs macular degeneration?

See below. A dystrophy is an inherited disorder where as a degeneration is acquired during life.
Genetics. Macular dystrophy is often cause by a defect in a gene for macular function, while age-related macular degeneration is not (currently known) to be caused by a gene malfunction, but from oxidative damage over time to the macula. Essentially it's genetics vs environment.
