Retinal Vessel Phenotype in Patients with Nonarteritic Anterior Ischemic Optic Neuropathy.

Purpose: The pathophysiology of nonarteritic anterior ischemic optic neuropathy (NAION) is not completely understood. Studies of the retinal vasculature phenotype in patients with NAION could help us to understand vascular abnormalities associated with the disease.

Design: Retrospective case series with matched control subjects.

Track-weighted imaging for neuroretina: Evaluations in healthy volunteers and ischemic optic neuropathy.

Background: The use of MRI-tractography to explore the human neuroretina is yet to be reported. Track-weighted imaging (TWI) was recently introduced as a qualitative tractography-based method with high anatomical contrast.

Purpose: To explore the human retina in healthy volunteers and patients with anterior ischemic optic neuropathy (AION) using TWI reconstructions.
