c-fos Controls the “Private Pathway” of Light-Induced Apoptosis of Retinal Photoreceptors
White light (5 klux for 2 hr) induces apoptosis of rod photoreceptors in wild-type mice (c-fos+/+) within 24 hr, whereas rods of c-fos knock-out mice (c-fos−/−) are protected (Hafezi et al., 1997b).Expand

Quantitative analysis of OCT characteristics in patients with achromatopsia and blue-cone monochromatism.
PURPOSE To quantify optical coherence tomography (OCT) images of the central retina in patients with blue-cone monochromatism (BCM) and achromatopsia (ACH) compared with healthy control individuals.Expand

Cholinergic effects on cat retinain vitro: Changes in rod- and cone-drivenb-wave and optic nerve response
To identify cholinergically mediated components in the optic nerve response (ONR) we studied effects of cholinergic agonists and antagonists in the arterially perfused cat eye. Acetylcholine,Expand

Dopamine influences the light peak in the perfused mammalian eye.
Dopamine, cis-flupenthixol, and dibutyryl cAMP affected the standing potential and light-evoked responses of the perfused cat eye in vitro. At micromolar concentrations, dopamine, a retinalExpand

Effects of changes in systemic blood pressure on the electroretinogram of the cat: evidence for retinal autoregulation.
Systemic blood pressure was increased and decreased in anesthetized cats by intravenous infusion of angiotensin and by gradual exsanguination, respectively. The b- and c-wave amplitudes of theExpand

Effects of changes in arterial Po2 and Pco2 on the electroretinogram in the cat.
Changes in components of the electroretinogram during hyperoxia, hypoxia, and hypercapnia were studied to demonstrate retinal vascular autoregulation by electrophysiologic means. Autoregulation ofExpand
