Glaucoma, one of the leading causes of blindness in the world, is characterized by progressive visual field loss and distinctive excavation of the optic nerve head. Although elevated intraocular pressure is the major risk factor, there is increasing evidence that the pathogenesis of glaucoma is also linked to altered ocular blood flow.

To the Editor.— Doppler ultrasound assessment of flow velocity in cerebral vessels in neonates has generated intense interest since the technique was originally applied to the preterm infant by Bada et al.1 The value and indication both as a research tool and useful clinical tool have yet to be defined.

Pediatrics, 1982
In the commentary, "Pulsatility Index, Patent Ductus Arteriosus, and Brain Damage," It was stated that we have shown that "blood flow" to the brain was not reduced in premature lambs with left-right ductal shunting. The abstracted data referred primarily to alteration of the percent distribution of blood flow and not to changes of absolute blood flow ...

The Flow of Blood in the Capillaries
Physics in Medicine & Biology, 1968A model consisting of right circular cylinders moving through a tube is chosen to represent the flow of corpuscles through the capillaries. A numerical solution of the equations of motion enables the flow to be considered in detail. The pressure gradient-volume flux relationships are calculated for different values of the parameters of the system. Flow

Transactions of the Society of Rheology, 1973
In this paper pulsatile blood flow through rigid circular tubes due to a sinusoidally varying pressure gradient is analyzed using a microcontinuum model of blood. A new boundary condition, which is in accord with experimental observations on blood flow in small rigid tubes, has been proposed to describe red blood cell rotations at a solid boundary ...

Hence does arise the action and function of the heart, which by pulsation it performs. [William Harvey, De Motu Cordis, 1628.] THE study of blood flow as a pulsatile phenomenon is scarcely new, but it has gained new impetus from three recent developments: the commercial production of reliable blood flowmeters, the formulation of theories appropriate to

Perfusion, 1995
We have reviewed briefly some features of the mechanics of blood flow, focusing particularly on the arterial system. Among the topics we consider are: steady and nonsteady flow in straight rigid tubes; the curvature and branching of arteries, noting that it may commonly be nonplanar; and the effects of both planar and nonplanar curvature and branching ...

Archives of Ophthalmology, 1979
In ophthalmology, laser-Doppler velocimetry (LDV) has been used for various types of measurements besides those of blood velocity. For example, it has been applied to investigate eye motion during smooth pursuit of a target [1] and the mechanical compliance of the optic nerve head [2].

1. The intramural blood vessels of the human colon have been described. 2. Five methods that have been used to study colonic mucosal blood flow in patients with colostomies or with normal colons were briefly outlined along with some of the limitations of each technic. 3.
