The form of the corneal indentation pulse is studied in various groups of patients by means of dynamic tonometry. Pathological alterations in ocular blood supply are associated with a corresponding change in the form of the recorded corneal indentation pulse. This may be of significance in the diagnosis of carotid occlusive disease, giant cell arteritis, and carotid-cavernous sinus fistula.
