Grain counts per unit area in different regions of optic nerve head with edema secondary to raised intracranial pressure. Grain counts have been corrected for glial and myelin correction factor. Grain counts for each curve taken from autoradiographic preparation of optic nerve head from eyes enucleated six hours and 1½, 3, 8, and 12 days after intravitreous injection of tritiated leucine.

Abbreviations: ALR = anterior part of nerve fiber layer; LC = lamina cribrosa; ML = anterior line of retrolaminar myelinated optic nerve; NFL = Nerve fiber layer; ON = optic nerve; PL = prelaminar region; PLR = posterior part of nerve fiber layer;
