In patients with mild to moderate myopia, the fundus is basically normal with no significant changes and can be followed up for observation. For patients with moderate to high myopia, there may be lesions in the fundus, such as vitreous opacities and posterior vitreous detachment, which can be treated with medication or observed. When the condition is severe and affects work and study, laser treatment can be performed to vaporize the vitreous clouding. Patients with high myopia may also develop a degenerative zone in the peripheral retina, and when this degenerative zone is likely to develop a fissure, laser treatment should be performed in a timely manner. Patients with macular hemorrhage and neovascularization in the macula can be treated with vitreous cavity injection. For highly myopic patients with retinal detachment, prompt surgical treatment is required. In addition, patients with posterior scleral staphyloma who have elongated eye axes can undergo posterior scleral buckling surgery to prevent progressive re-expansion of the sclera. These are the treatment modalities for high myopia and common myopia.
