We review the cellular and physiological mechanisms responsible for the regulation of blood
flow in the retina and choroid in health and disease. Due to the intrinsic light sensitivity of the …

Two principal theories for the pathogenesis of glaucomatous optic neuropathy (GON) have
been described—a mechanical and a vascular theory. Both have been defended by various …

The retinal and cerebral microvasculatures share many morphological and physiological
properties. Assessment of the cerebral microvasculature requires highly specialized and …

As digital imaging and computing power increasingly develop, so too does the potential to
use these technologies in ophthalmology. Image processing, analysis and computer vision …

Glaucoma is an optic neuropathy of unknown origin. The most important risk factor for the
disease is an increased intraocular pressure (IOP). Reducing IOP is associated with …

The purpose of the present study was to investigate the contribution of basal nitric oxide
(NO) on retinal vascular tone in humans. In addition, we set out to elucidate the role of NO in …

Acta Ophthalmol. 2010: 88: 717–722 Abstract. The present article describes a standard
instrument for the continuous online determination of retinal vessel diameters, the …

In the recent years it has been recognized that nitric oxide is an important regulator of ocular
blood flow. Nitric oxide is involved in the control of basal blood flow in the choroid, optic …

Background/aim: Stimulation of the retina with flickering light increases retinal arterial and
venous diameters in animals and humans, indicating a tight coupling between neural activity …

OBJECTIVE—Stimulation of the retina with flickering light increases retinal vessel diameters
in humans. Nitric oxide is a mediator of the retinal vasodilation to flicker. The reduction of …
