| Popis: |
Visual acuity measured using the Snellen method in 29 patients with hypophyseal tumors amounts to normal or nearly normal values (6/9-6/6), with mean value of 0.75. Measuring of visual acuity with the more accurate "log MAR" optotype tables yields acuity values which decline with the severity of the disease from 1.04 to 0.87 with a mean value of 0.97. Not withstanding, in all of these patients markedly lowered contrast sensitivity values were found in all of the frequencies tested (1.15-29.25 c/deg). The use of the visual acuity determinations only is insufficient for early detection of functional visual disturbances in compressions of the visual pathway. |
