Abstract
Analysis of how retinal ganglion cells change in retinal degeneration is critical for evaluating the potential of photoreceptor restorative therapies. Immunocytochemistry in combination with image analysis provides a way for quantifying not only the density of ganglion cells during disease, but also information about their morphology and an evaluation of excitatory and inhibitory synaptic inputs. Here, we describe how indirect immunofluorescence can be used in retinal whole mounts to obtain information about ganglion cells in retinal degeneration.
