High myopia patients, please note that high myopia will have fundus changes

Abstract: due to the gradual elongation of the ocular axis, the choroid around the optic papilla is separated from the temporal side of the optic papilla under the traction of the scleral extension force, and the sclera behind the right of use is exposed to form a white arc spot. If the posterior pole of the eyeball continues to expand and extend, the posterior sclera is exposed to form white arc spots.

due to high myopia, the eyeball elongates backward, the retinal vessels become thinner after leaving the optic papilla, and the choroidal vessels straighten accordingly. Thinning.

and

at the same time, due to the dystrophy of pigment epithelium, dystrophy of superficial pigment epithelium and disappearance of superficial pigment, the choroidal vessels are more exposed and present leopard shaped fundus.

due to the gradual elongation of the ocular axis, the choroid around the optic papilla is separated from the temporal side of the optic papilla under the traction of the scleral extension force, and the sclera behind the right of use is exposed to form a white arc spot. If the posterior pole of the eyeball continues to expand and extend, the posterior sclera is exposed to form white arc spots.

if the posterior pole of the eyeball continues to expand, the detachment of the choroid gradually extends from the temporal side of the nipple to around the optic nipple, causing circular arc spots. The choroid between the optic papilla and macula is prone to degeneration because the force of sclera extension constantly pulls the retina and fatty collateral membrane at the posterior pole. Atrophy and bleeding. Bleeding penetrates into the choroid or retina. If it is not fully absorbed, it will cause mechanization and make the choroid and retina of the corresponding parts lose their normal function.

if it happens to be in the macular area where things are most sensitive, it will reduce vision. In addition, retinal detachment can be caused by degeneration of the peripheral part of the retina to form a hole, coupled with vitreous opacity or liquefied traction.
