Infrared angiography of the cat fundus oculi.

Infrared absorption angiograms of the cat fundus were obtained by regional arterial injection of indocyanine green. There was better resolution of the retinal circulation than that obtained by intravenous injection, but in the choroid only choriocapillaris filling was seen.

[Hemodynamics of the fundus oculi and brain of patients with parasagittal meningiomas].

The retinal blood flow was studied by fluorescent angiography of the fundus oculi in 22 patients with parasagittal meningiomas before and after surgery. A total of 82 fluorescence-angiographic examinations were performed and disorders of retinal hemodynamics were found irrespective of the presence or absence of intracranial hypertension. Prolongation of the venous phase of retinal circulation alone without signs of intracranial hypertension is an early symptom of impaired venous flow from the cranial cavity and deficient development of pathways compensating for venous drainage. The arterial phase is prolonged at a later stage of the tumorous process, when the cerebral blood flow is much slower. Marked disorders of retinal venous blood flow are still found one month after removal of parasagittal meningiomas. It is shown that the flow of venous blood from the cranial cavity is mainly impaired in patients with parasagittal meningiomas.
