Glial cells in the optic nerve of Pholidapus dybowskii were observed by the Golgi silver impregnation method. Subtypes of protoplasmatic astroglia
(free strongly ramified glia), perivascular macroglia (connected with vessels, ramified glia), and oligodendroglia were selected in concordance with the position of cell plexus.
By correlative analysis of cell morphological characteristics, obtained by the Leontovich method of cell measuring, some cell features were discovered. The features positively
correlated with the capacity of cell branch territory. Correlation coefficients of these features varied from 0.40 to 0.98. Groups of features with a high correlation coefficient were
assumed as a basis for recognition of the detailed glial subtypes. Valid differences (P = 0.95) between the detailed glial subtypes were found. The main feature has a
reliable difference equal to P = 0.99. Group of constant features were discovered, which define the overall performance of glial cells. Among glial cells, modification of
capacities of cell branch territory was measured.
