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.
In many cases, myopia will stabilize once the growth process has been completed, but in more severe chronic cases, loss of vision can occur. Degenerative myopia, also known as malignant, pathological, or progressive myopia, is characterized by posterior sclera elongation and thinning (at least 25.5 mm to 26.5 mm) and high refractive errors of ...
Layers of the eye, with the choroid labelled. Choroidal neovascularization (CNV) is the creation of new blood vessels in the choroid layer of the eye.Choroidal neovascularization is a common cause of neovascular degenerative maculopathy (i.e. 'wet' macular degeneration) [1] commonly exacerbated by extreme myopia, malignant myopic degeneration, or age-related developments.
In myopia that is no longer progressing, the crescent may be asymptomatic except for its presence on ocular examination. However, in high-degree myopia, it may extend to the upper and lower borders, or form a complete ring around the optic disc and form a central scotoma. The myopic crescent is commonly seen in pathological axial myopia.

High myopia usually describes myopia of −6.00 or more. [65] [84] People with high myopia are more likely to have retinal detachments [85] and primary open angle glaucoma. [86] They are also more likely to experience floaters, shadow-like shapes which appear in the field of vision. [87]
The fundus of the eye is the interior surface of the eye opposite the lens and includes the retina, optic disc, macula, fovea, and posterior pole. [1] The fundus can be examined by ophthalmoscopy [ 1 ] and/or fundus photography .
Fundus photography in animals: Fundus photography is a useful tool utilised for veterinary research, veterinary ophthalmology, as well as education. [20] Numerous studies have used it as a research method for the study of ocular and systemic conditions in animals.
