As a special type of refractive eye disease, high myopia (HM) not only causes progressive and degenerative fundus changes, but also has a high prevalence of optic nerve damage. Glaucoma is the most common form of irreversible blinding eye diseases worldwide, among which, primary open-angle glaucoma (POAG) is the most common type. In recent studies, HM is found to have similarities on pathological changes as that of POAG. And HM fundus changes are easily confused with early stage POAG fundus changes; thus, the early detection of POAG on HM patients is highly important on disease deferment or prevention of disease progression. Macular degeneration as well as optic nerve morphology and structural changes are to be observed in the long-term follow-up for HM patients.
