Summary Using a reduced‐silver method, this study examined ganglion‐cell 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° 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.
