• mice show progressive alteration and remodeling of the laminar retinal structure from P16 to P45
• however, no major defects in neuroepithelial cell polarity or in structure of adherens junctions are seen in immature retinas at P2
• mice show the formation of photoreceptor rosettes at P16 (circular structures comprising photoreceptors only that are oriented toward an internal lumen with photoreceptor outer segments protruding inward) that increase in number from P16 and P45 and decrease in size and eventually disappear by 3 months of age when degeneration of photoreceptors begins
• rosettes are scattered along the retinal outer surface and are composed of photoreceptors and their synaptic terminals
• photoreceptors with rosettes degenerate as mice reach 3 months of age
• the outer nuclear layer becomes progressively thinner; it is thinner in the peripheral compared with the central retina, indicating a periphery-to-central degenerative gradient
• formation of photoreceptor rosettes at P16 progresses to more general cellular disorganization
• widespread degeneration of retinal cell types with age
• Muller cells become hypertrophic with radial processes increasing in size and GFAP reactivity increasing at later stages during when loss of retinal cells is occurring, indicating glial activation
• scotopic a wave amplitude is diminished at 1, 3, and 5 months of age
• scotopic and photopic b wave amplitudes are diminished

• retinoblastoma cells that express amacrine/horizontal cell markers also extend processes and form synapses; some of these Golgi-Cox-labeled cells extend 1-3 long main processes with further neurite branching characteristic of horizontal or wide-field amacrine cells, while more (nearly half of ) labeled cells extend a main process with extensive neurite outgrowth characteristic of amacrine cells, and the remaining cells are less differentiated with short, unbranched neurites
