Fuchs spot
Encyclopedia
The Fuchs spot or sometimes Forster-Fuchs' retinal spot is a degeneration of the macula
in case of high myopia
. It is named after the two persons who first described it: Ernst Fuchs
who described a pigmented lesion in 1901 and Forster
who described subretinal neovascularisation
in 1862. The size of the spots are proportionate to the severity of the pathological myopia.

Macula
The macula or macula lutea is an oval-shaped highly pigmented yellow spot near the center of the retina of the human eye. It has a diameter of around 5 mm and is often histologically defined as having two or more layers of ganglion cells...

Macular degeneration
Age-related macular degeneration is a medical condition which usually affects older adults and results in a loss of vision in the center of the visual field because of damage to the retina. It occurs in “dry” and “wet” forms. It is a major cause of blindness and visual impairment in older adults...
