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]
Symptoms and signs
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]

Treatment
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]
