Optic nerve head injury and optical coherence tomography angiography
Dear editors, We wrote this letter to discuss the microvascular abnormalities related to optic nerve head (ONH) injury visualized by optical coherence tomography angiography (OCTA). With the advent of OCTA, different fundus vasculature levels in the macular region can be displayed precisely and noninvasively to investigate its mechanisms. OCTA is a promising diagnostic approach for detecting inflammatory, ischemic, and compressive optic neuropathies ( 1 ). However, the potential relationship between parapapillary microvascular dysfunction and ONH injury is still unclear and should be investigated by combined structural and functional OCT. The macula and the ONH’s different microvasculature results in a weaker association ...
