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.
Each fundus has no sign of disease or pathology. The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disc is located towards the nose. Both optic discs have some pigmentation at the perimeter of the lateral side, which is considered non-pathological.
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.
Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses.This can include various methods of surgical remodeling of the cornea (keratomileusis), lens implantation or lens replacement.
