A leopard fundus alone does not cause blindness in the eye. A leopard fundus is a specific fundus manifestation of high myopia. In highly myopic eyes, the eye axis is long and the retina is stretched thin, so the blood vessels in the choroid below can be seen through the retina in a leopard-like pattern, called leopard fundus. When the leopard-like fundus is combined with pathological changes, such as peripheral lattice-like degeneration, choroidal atrophy foci, retinal fissures, vitreous liquefaction gradually entering the retina through the fissures, resulting in retinal detachment or combined with macular choroidal neovascularization, neovascular rupture and hemorrhage, it will cause a rapid loss of vision or even blindness.
