    Spectral Domain-Optical Coherence Tomography of the Vitreopapillary Interface in Acute Non-Arteritic Anterior Ischemic Optic Neuropathy

    Purpose To use spectral domain-optical coherence tomography (SD-OCT) to assess whether epipapillary vitreous traction from evolving posterior vitreous detachment (PVD) is mechanistically involved in the pathogenesis of non-arteritic anterior ischemic optic neuropathy (NAION). Design Retrospective cohort study. Methods.Setting Single academic center. Patient or study population Eighty eyes in 74 subjects presenting within 2 weeks of symptom onset of NAION. Intervention or observation procedures SD-OCT imaging of the optic nerve head, macula, and peripapillary retinal nerve fiber layer (pRNFL) were reviewed for PVD and vitreopapillary traction (VPT). Main Outcome Measures Prevalence and incidence of PVD and VPT, logMAR best-corrected visual ...
