The correlation coefficients between the mean PBR-positive cell numbers in LGN layers receiving input from glaucoma eye and percent changes of GFAP-, Iba-1-immunoreactivity, or soma size in LGN, or optic nerve axons were 0.512 (P = 0.378, n = 5), 0.064 (P = 0.918, n = 5), −0.199 (P = 0.748, n = 5), and −0.426 (P = 0.475, n = 5), respectively. This evidence concerns the gene GFAP and glaucoma.
