Computational simulation of Haidinger’s Brushes

Published on 2018-05-10T15:36:28Z (GMT) by
Haidinger’s Brushes (HB) are entoptic phenomena resulting from differential absorption of linear polarized light by the human macula. Computational models have assisted in understanding the behavior of these subjective phenomena, but have been limited in their application. This study presents a revised computational model that incorporates known determinants of the form and behavior of HB. The model generates both static and animated simulations of HB that can be quantified by their density, contrast and radial/circumferential extent. Measured physiological parameters are used to demonstrate the dependency of HB on macular pigment (MP) density, MP distribution and ocular retardation. Physiological variations in these parameters explain the reported variations in the perception of HP.
