Abstract:  The complex microstructures of optic nerve head (ONH) can be observed in vivo with the development of optical coherence tomography, which deepens the acknowledgement of many clinical entities. This article elucidates the observable microstructures of ONH such as the marginal tissues of Elschnig and their clinical applications. The etiology, pathophysiological mechanism, nomination, differential diagnosis and prognosis of optovenous collateral is explored and analyzed in depth based on description of blood supply of ONH.  (Ophthalmol CHN, 2024, 33: 321-328)

Key words:  optic nerve head, the marginal tissues of Elschnig, optovenous collateral, optic disc neovascularization
