摘要：

An experimental study of lateral displacement of ganglion cells (GCs) from foveal cones in six human retinas is reported. At 406675 gm in length, as measured in radially oriented cross-sections, Henle fibers are substantially longer than previously reported. However, a Dew theoretical model indicates that the discrepancies in these reports are mainly due to meridional differences. The model takes into account the effects of optical degradation and peripheral ON/OFF asymmetry and predicts a central GC:cone ratio of 2.24:1. It provides estimates of cumulative counts and GC receptive field density at 0 degrees-30 degrees along the principal meridians of the visual field. (C) 2007 Elsevier Ltd. All rights reserved.
