Comment on Age-Dependent Deformation of the Optic Nerve Head and Peripapillary Retina by Horizontal Duction

Fundus angiography supports the idea that NAION stems from acute hypoperfusion in a crowded disc.4 The perfusion defect is related to anomalies in local or systemic hemodynamics. In a patient already at risk of NAION, these biomechanics may retard blood flow sufficiently to tip a disc into acute inf...

Summary:Fundus angiography supports the idea that NAION stems from acute hypoperfusion in a crowded disc.4 The perfusion defect is related to anomalies in local or systemic hemodynamics. In a patient already at risk of NAION, these biomechanics may retard blood flow sufficiently to tip a disc into acute infarction. Hayreh reported that his large number of NAION patients had usually found their visual loss on waking from sleep.5 Accordingly, he studied the role of nocturnal hypotension in NAION.
