Foveal Sparing: New Anatomical Evidence for Bilateral Representation of the Central Retina

Foveal Sparing: New Anatomical Evidence for Bilateral Representation of the Central Retina Abstract • The pattern of retinal ganglion cell projections to the dorsal lateral geniculate nuclei has been demonstrated with horseradish peroxidase neuronography. A 1°-wide strip centered on the vertical meridian has been found in which ipsilaterally and contralaterally projecting ganglion cells intermingle. This strip expands to a width of 3° at the fovea, since mixing of horseradish peroxidase-labeled and unlabeled ganglion cells was found in a band approximately 0.5° wide along both the nasal and temporal rims of the foveola. These labeled ganglion cells rimming the foveal pit in Its entirety represent a possible anatomical basis for "foveal sparing." (Arch Ophthalmol 95:1445-1447, 1977) References 1.
