PURPOSE The retinal nerve fiber layer (RNFL) exhibits linear birefringence due to the oriented cylindrical structure of ganglion cell axons. The birefringence (Deltan) depends on the density and composition of axonal organelles. The purpose of this study was to evaluate the distribution of birefringence around the optic nerve head (ONH) in normal subjects. METHODS Birefringence was calculated along circular scan paths around the ONH as Deltan = R/T, where R is RNFL retardance measured by… CONTINUE READING
