AIMS Slit lamp fundus biomicroscopy allows for high magnification, stereoscopic diagnosis, and treatment of macular diseases. Variable contrast, narrow field of view, and specular reflections arising from the cornea, sclera, and examining lens reduce image quality; these images are of limited clinical utility for diagnosis, treatment planning, and photodocumentation when compared with fundus ca...

Quantitative analysis of innervation to dorsal motor nucleus of the vagus (DMV) fundus-projecting neurons indicates that approximately 17% of input neurons are noradrenergic. To determine whether this small percentage of neurons innervating DMV output to the stomach is physiologically relevant, we evaluated the role of norepinephrine at the DMV in mediating a vagovagal reflex controlling the fu...

INTRODUCTION Examination of the ocular fundus is a fundamental component of the general physical examination and critical to the diagnosis of lifeand sight-threatening medical conditions among patients with certain presenting complaints, such as headache. In addition, populationbased studies have shown the prognostic value of retinal microvascular findings in cardiovascular and neurologic disea...

introduction sectoral retinitis pigmentosa (rp) is a rare clinical condition. case presentation we present a 60-year-old female with a history of mild night blindness and decreased vision in the left eye for about 15 years. conclusions fundus examination revealed retinal pigmentary changes in the inferotemporal sector and reduced arterial caliber. in addition, fundus autofluorescence, fluoresce...

AIMS To process video slit lamp biomicroscopic fundus image sequences in order to generate wide field, high quality fundus image montages which might be suitable for photodocumentation. METHODS Slit lamp biomicroscopic fundus examination was performed on human volunteers with a contact or non-contact lens. A stock, charge coupled device camera permitted image capture and storage of the image ...

AIMS/BACKGROUND Recently a laser interferometric method for topical measurement of fundus pulsations has been developed. Fundus pulsations in the macular region are caused by the inflow and outflow of blood into the choroid. The purpose of this work was to study the influence of a peripheral vasoconstricting (the alpha 1 adrenoceptor agonist phenylephrine), a predominantly positive inotropic (t...

Fasting gastric fundus tone is maintained by continuous cholinergic input. 5-Hydroxytryptamine-1 (5-HT1) receptor activation decreases gastric fundus tone in humans. Whether this fundus-relaxing effect is mediated via inhibition of cholinergic input or via activation of a nitrergic pathway is unknown. The aim of the present study was to determine the effect of nitrergic inhibition on feline gas...

purpose : to report a case of purtscher retinopathy associated with valsalva retinopathy after car accident methods : a 54-year-old man presented with a sudden visual loss in his left eye after car accident. fundus examination of the left eye showed cotton-wool spots and retinal hemorrhages in the posterior pole associated with subhyaloid hemorrhage in macula. results : fundus examination showe...

Fundus photography in adults and cooperative children is possible with a fundus camera or by using a slit lamp-mounted digital camera. Retcam TM or a video indirect ophthalmoscope is necessary for fundus imaging in infants and young children under anesthesia. Herein, a technique of converting and using a digital video camera into a video indirect ophthalmoscope for fundus imaging is described. ...

BACKGROUND Ocular involvement in pregnancy-induced hypertension (PIH) is common. OBJECTIVE To study the association between pregnancy-induced hypertensive fundus changes and fetal outcomes. SUBJECTS AND METHODS A prospective cohort study was carried out including 153 subjects with the diagnosis of PIH. The subjects were evaluated for hypertensive fundus changes. Fetal outcomes were assessed...
