[On the appearance of the eye fundus in polycythaemia vera (author's transl)].

The authors discuss the ophthalmological and physical symptoms of polycythaemia vera. They established that the severity of the changes in the fundus depend in the same way on the red cell count and the duration of the illness. In an attempt to find the cause of the complications communicated in the literature in arterial spasm and venous stasis, the authors compared statistically the less severe cases and those cases with arterial stenosis which can also be found in uncomplicated cases, and the cases with venous stasis. In the group with arterial stenosis they showed that its occurrence was not associated with the hypertension often found in polycythaemia vera.
