Immunocytochemistry was per formed with unsectioned whole retinae or retinal pieces.
The total number of microglia cells was at the level of control retinae one week after treatment.
These pigments even failed to bleach after hours of bright-field illumination of fixed and unfixed retinae.
Given the current taxonomic status of the insectivores, it is unlikely that their retinae represent a "primitive", prototypic arrangement.
There are methodological differences between the research reported here and that undertaken on human retinae.
Three different rabbit retinae were used and the density of labeled cells was found to be similar in each case.
This orientated each specimen such that dorsal and ventral regions were clearly distinguishable when mounting the final processed retinae.
Orientation of retinae was distinguished by the longest cut made toward the dorsal aspect.
