Estimation of normal and glaucomatous optic nerve morphology from perfusion.

Objective: To estimate the optic nerve head morphology from its haemoglobin (Hb) distribution.

Methods And Analysis: The optic disc of 189 normal eyes and 292 with confirmed and suspected glaucoma were analysed with Spectralis-OCT and the Laguna ONhE application using the Topcon NW400 fundus camera. Topographic Hb values were correlated with OCT tissue thicknesses from Bruch's membrane.
