Examples of horizontal B-scans from the P42, OIR eye shown en
face in Figure-1. Laminar
disruptions (black arrows) were detected in the living eye, demonstrating that
disruptions and intermixing of nuclei between the inner nuclear layer (INL) and
outer nuclear layer (ONL), seen in fixed retinal tissue sections, are not
artifacts of histology processing. The numbers of larger disruptions were
greater in the inferior retina compared to the superior retina. The optical
back-scattering density of tissue disruptions was also greater in the inferior
retina. Horizontal B-scan locations shown are (A) superior (y
= +0.47mm), (B) central (y = 0.0 mm) and
(C) inferior (y = −0.47 mm). The retinal layers
visible are labeled: NFL/GCL (nerve fiber layer / ganglion cell layer), IPL
(inner plexiform layer), INL/OPL/INL (inner nuclear layer / outer plexiform
layer / outer nuclear layer), RPE (retinal pigment epithelium).
