Abstract´╝Ü High myopia (HM) is one of the main causes of vision loss. In recent years, optical coherence tomography and other techniques have shown a variety of vitreoretinal interface abnormalities (VRIA) in highly myopic eyes. Posterior vitreous detachment and paravascular abnormality are the relatively common manifestations of VRIA. Posterior vitreous detachment is classified in several different ways in HM eyes, the onset age of which is earlier in HM. Paravascular abnormality mainly includes paravascular microfold, paravascular cyst, paravascular lamellar hole, and paravascular retinoschisis. The former two are early-stage lesions, the latter two are advanced lesions. VRIA is closely related to many HM's fundus complications, such as myopic retinoschisis, macular hole, retinal detachment and so on. VRIA may develop into myopic retinoschisis, which in turn develop into full-thickness macular hole, and even retinal detachment. Therefore, the examination and judgment of VRIA in HM patients are of great significance for the early prevention and treatment of clinical retina diseases.
