Why the study?
Does dynamic tonometry correlate with internal carotid artery flow during graded occlusion in patients with I.C.A. aneurysms?
Does dynamic tonometry correlate with internal carotid artery flow during graded occlusion in patients with I.C.A. aneurysms?
Dynamic tonometry correlates closely with internal carotid artery flow and can act as a guide during graded I.C.A. occlusion.

May guide monitoring during graded carotid occlusion; single-case data leaves prospective validation open.
Graded occlusion of the internal carotid artery (I.C.A.) was performed under simultaneous I.C.A. flowmetry and dynamic tonometry in 10 cases of I.C.A. aneurysms. A close correlation between I.C.A. flow and corneal indentation pulse amplitudes was found, indicating that dynamic tonometry can act as a guide during graded I.C.A. occlusion, either alone or together with I.C.A. flowmetry. In addition, the information obtained in this controlled study is valuable for a better understanding of the results obtained by dynamic tonometry in cases of carotid occlusive disease.
