Fuchs spot
The Fuchs spot is a degeneration of the macula occurring in cases of high myopia.
-
Named after Ernst Fuchs and Forster, who independently described aspects of the condition.
source quote
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 neovascularization in 1862.
-
Pathogenesis involves proliferation of retinal pigment epithelium with choroidal hemorrhage.
source quote
It occurs due to proliferation of retinal pigment epithelium associated with choroidal hemorrhage.
-
Spot size correlates with severity of pathological myopia.
source quote
The size of the spots are proportionate to the severity of the pathological myopia.
-
Initial symptom is distortion of straight lines near the fovea.
source quote
First signs of a Fuchs spot are distorted sight of straight lines near the fovea
-
Days later, well-circumscribed patches form after hemorrhage absorption, leaving a pigmented scar.
source quote
some days later turn to the typical well-circumscribed patches after absorption of haemorrhage , and a pigmented scar remains
-
Central vision is affected, similar to macular degeneration.
source quote
As in macular degeneration , central sight is affected.
-
Fuchs spots result from regression of choroidal neovascularization.
source quote
Fuchs spots are caused by regression of choroidal neovascularization.
-
As a medical sign, treatment targets the underlying cause.
source quote
Since it is a medical sign, treatment is given for the actual cause.
-
Options include photothermal laser ablation, photodynamic therapy, anti-VEGF therapy, or combinations thereof.
source quote
Photothermal laser ablation, photodynamic therapy, anti-VEGF therapy, or a combination of these are the treatment options of choroidal neovascularization due to pathological myopia.

The Fuchs spot (also known as Förster-Fuchs' Spot[1]) is a degeneration of the macula in cases 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 neovascularization in 1862.[2] It occurs due to proliferation of retinal pigment epithelium associated with choroidal hemorrhage.[1] The size of the spots are proportionate to the severity of the pathological myopia.[citation needed]
First signs of a Fuchs spot are distorted sight of straight lines near the fovea, which some days later turn to the typical well-circumscribed patches after absorption of haemorrhage, and a pigmented scar remains. As in macular degeneration, central sight is affected. Atrophy leads to the loss of two or more lines of the Snellen chart.[citation needed]
Fuchs spots are caused by regression of choroidal neovascularization.[3] Since it is a medical sign, treatment is given for the actual cause. Photothermal laser ablation, photodynamic therapy, anti-VEGF therapy, or a combination of these are the treatment options of choroidal neovascularization due to pathological myopia.[3][1]
