Dog retinal ganglion cells: a morphological and morphometrical study in aging.
Using a reduced-silver method, this study examined ganglioncell morphology and morphometry in aging dog wholemount retina. The ganglion-cell body size and topography were obtained using a semi-automatic image analyser (Leitz ASM 68K, Wetzlar, Germany) studying a sector (with an angle of 10 degrees centred on the optic papilla) as a sampling area from the superior, middle and inferior regions of nasal and temporal retina. The ganglion-cell type and topography of the elder dog retina resembled those of cat retina, with the exception of a lack of alpha cells in the peripheral area of the temporal retina. However, the morphological and morphometrical features are not influenced by aging.
