Figure 8. Histological evaluation of the optic disc with various pressure-insult. Pressure-insult dependent optic disc damages were histologically evaluated with the laser-treated eyes. The surrogate values of the pressure-insult are B: 53, D: 126, F: 294 and H: 557. Light microscopic images indicate the laser-treated B: D:F:H: and the contralateral control (A, C: E:G: respectively) eyes. Scale bar indicate 50 μm. These figures indicate that the optic disc cupping become larger as the surrogate value is higher.
