[Influence of fundus sclerosis and blood pressure on the ability of compensation of ocular circulation (author's transl)].

The visual fields of nine eyes (nine patients, aged 51--60 years) with fundus sclerosis and relatively low systemic blood pressure, as well as the visual fields from 25 eyes (25 patients, aged 51--60 years) with increased blood pressure, but no ophthalmologic evidence of arteriosclerosis or fundus sclerosis were investigated with the Goldmann Perimeter before and after the application of pressure to the eye. In the first group pressure application resulted in a narrowing of the I/4-isopters and a marked narrowing of the I/2-isopters of the visual field. The blind spot scotomes become larger and are excluded from the I/2-isopters by their marked narrowing. In contrast, the I/4-isopters on the second group of eyes are little influenced by pressure application and I/2-isopters are never narrowed to an extent which excludes the blind spot from the I/2 scale.
