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.
对22例矢状窦旁脑膜瘤患者在手术前后通过眼底荧光血管造影术研究视网膜血流。共进行了82次荧光血管造影检查，发现无论有无颅内高压，均存在视网膜血流动力学紊乱。仅视网膜循环静脉期延长而无颅内高压体征是颅腔静脉血流受损及代偿静脉引流的通路发育不全的早期症状。在肿瘤病程后期，当脑血流明显减慢时，动脉期延长。矢状窦旁脑膜瘤切除术后1个月仍可发现明显的视网膜静脉血流紊乱。结果表明，矢状窦旁脑膜瘤患者主要存在颅腔静脉血流受损。
