Labeling of synaptic inputs to ganglion cells in glaucomatous DBA/2J retinas.

A, Digital representation of a non-glaucomatous (D2.Gpnmb+) retina. B, Higher magnification of the boxed area in panel A, showing the density of excitatory synaptic inputs to a higher-order dendrite. C & E, Two examples of ganglion cells from glaucomatous DBA/2J mice. The dendritic remodeling is obvious. D & F, Higher magnification views of the boxed areas in panels C and E, respectively. Overall synaptic density is lower than in the non-glaucomatous ganglion cells.
