“…11,21,22 Furthermore, recent studies demonstrated RNFL loss in patients with occipital lobe lesions 14 and after acquired lesions of the brain even in areas other than the occipital lobe 15,16 through the process of retrograde transsynaptic degenerations of neurons. [14][15][16] This is interesting as we studied adult patients with NF1 with no history of OPG and found thinning of the mean pRNFL (P = 0.003), RNFL (P = 0.022), and GCL-ILP (P , 0.001) layers reflecting axonal and neuronal loss. It is known that NF1 is characterized by aberrant proliferation of multiple tissues of neural crest origin.…”
