Visual resolution of retinal ganglion cells in monocularly-deprived cats.

The spatial resolution of 87 on-centre retinal ganglion cells was measured at different retinal eccentricities in the retina of the deprived eye of two monocularly-deprived cats. Intra-ocular recording techniques were employed in order that particular attention could be placed on ganglion cells in the region of the area centralis. The spatial cut-off frequencies of both major classes on-centre ganglion cells were comparable to those observed in normal retinas at similar retinal eccentricities. In particular there was no evidence of any loss of spatial resolution of either class of cell in the vicinity of the area centralis as has been reported in the retina of the deviating eye of strabismic cats.
