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 To report clinical features of bilateral angle-closure glaucoma in a patient with nanophthalmic eyes associated with ocular cystinosis, foveoschisis and pigmentary retinal dystrophy. This is probably the first published report of the possible association of all these five entities in the same patient. CASE PRESENTATION A 50-year-old white male was referred for uncontrolled glaucoma...

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...

Ca+/calmodulin-dependent protein kinase II (CaM kinase II) is regulated by calcium oscillations, autophosphorylation, and its subunit composition. All four subunit isoforms were detected in gastric fundus and proximal colon smooth muscles by RT-PCR, but only the gamma and delta isoforms are expressed in myocytes. Relative gamma and delta message levels were quantitated by real-time PCR. CaM kin...

Angioid streaks are rare lesions of the fundus, which often associated with general pathologies. These stripes that visible at dark in appearance, and diverge from papilla. They due to anomalies elastic fibers there is a deposit calcium. described many pathologies: Paget's disease; Sickle cell disease Marfan's syndrome. There no treatment for angioid streaks. We report case patient presenting a...

BACKGROUND AND OBJECTIVE Measurements performed on fundus images using current software are not accurate. Accurate measurements can be obtained only by calibrating a fundus camera using measurements between fixed retinal landmarks, such as the dimensions of the optic nerve, or by relying on a calibrated model eye provided by a reading center. However, calibrated spectral domain OCT (SD-OCT) cou...
