We evaluated the extent of pallor on the walls of the optic cup three-dimensionally using simultaneous stereophotographs of the optic discs of 29 normals, 29 ocular hypertensives and 28 primary open angle glaucomas. Pallor was located at the bottom of the optic cup. Pallor ascends the walls of the cup as its extent increases. Statistically significant differences in the extent of pallor in all four quadrants of the optic cup were observed, with the glaucomas having greater extents of pallor than ocular hypertensives, and the ocular hypertensives greater than the normals. The greatest percentage increase in mean pallor from normals to open angle glaucomas occurred on the nasal and inferior walls. This differential extent of pallor could be useful in characterizing ocular hypertension and chronic open angle glaucoma.
我们使用29名正常人、29名高眼压症患者和28名原发性开角型青光眼患者视盘的同步立体照片，对视杯壁苍白程度进行了三维评估。苍白位于视杯底部。随着苍白范围的增加，其沿着视杯壁上升。在视杯的所有四个象限中，苍白程度存在统计学上的显著差异，青光眼患者的苍白程度大于高眼压症患者，高眼压症患者大于正常人。从正常人到开角型青光眼，平均苍白程度增加百分比最大的是鼻侧和下壁。这种苍白程度的差异可能有助于鉴别高眼压症和慢性开角型青光眼。
