Abstract: Objective · To investigate the relationship between pathological myopia and  classification of vitreoretinal interface features using enhanced vitreous imaging optical coherence tomography (EVI-OCT).  Methods · High myopia patients were included from 2015 to 2016. All participants underwent standardized medical interviews and ophthalmic examination.  Results · The included eyes were divided into two groups of pathological myopia and simple high myopia based on myopic macular degeneration observed on fundus photography . There were four types of vitreoretinal interface changes demonstrated on EVI-OCT scans in included eyes: Type1, posterior precortical vitreous pockets (PPVP), Type2, partial posterior vitreous detachment with vitreous adhesion (VA), Type 3, epiretinal membrane (ERM), and Type 4, no traction (NT).  Pathological myopia was mostly detected in VA, ERM, and NT groups.  Conclusion · EVI-OCT was able to demonstrate the early changes of vitreoretinal interface in high myopia eyes. Vitreous adhesions and traction detected by OCT may facilitate the occurrence of pathological myopia.

Key words:  pathological myopia, vitreoretinal interface features, enhanced vitreous imaging optical coherence tomography
