To better understand the disparity frequently seen between optic pathway glioma (OPG) characteristics and visual loss among young children with neurofibromatosis type 1 (NF1), we extend our previous findings of anatomic, physiologic, and behavioral abnormalities in an established animal model. We now report differential effects of treatment targeting the MAPK/ERK cellular pathway: 1) preserving retinal ganglion cell (RGC) number, and yet 2) failing to ameliorate demyelination of the retrobulbar optic nerve.
