Retinal nerve fiber layer thinning in Parkinson disease

Vision Research, 2004
Retinal dopamine loss in Parkinson disease (PD) is reflected by visual neurophysiological dysfunction. We measured the thickness of the circumpapillary retinal nerve fiber layer (RNFL) in PD patients using optical coherence tomography. The thickness in the inferior quadrant of PD patients (147 +/- 20 microns) was significantly thinner than that of ...

Conformal geometry of the retinal nerve fiber layer [PDF]

Proceedings of the National Academy of Sciences, 2008
The nerve fiber layer of the human retina is made up of the retinal segments of ganglion cell axons. Its geometry can be described mathematically as a fibration of a 2D domain: a partition of a certain region into smooth curves. Here, we present a simple family of curves that closely models the observed geometry of the nerve fiber layer.
