STUDY OBJECTIVES To study the effect of tracheal intubation or laryngeal mask airway (LMA) insertion on intraocular pressure (IOP) in strabismus patients undergoing balanced anesthesia with sevoflurane and remifentanil. DESIGN Open, prospective, randomized study. SETTING Tertiary care academic medical institution. PATIENTS 40 adult ASA physical status(More)
BACKGROUND Multifocal electroretinography allows simultaneous recording of 61 focal electroretinographic signals from the retina of the posterior pole. The function of the outer retinal layers can be mapped for a visual field of 30.5 degrees radius. We herein describe the topography of such potentials in patients with hemianopic and concentric visual field(More)
1, Methods The DMM was designed to measure light sensitivity threshold to a white stimuli at 100 locations on a 5” region of 1” resolution at the lmacula using Humphrey Field Analyzer-640 in 24 eyes of the normal elderly. The age range was 50-69. The test of routine threshold programma 10-2 was compared. The statistical analysis was carried out for(More)
PURPOSE In earlier studies it was shown that patients with vascular disturbances (e.g. sudden hearing loss) had white-noise field campimetry abnormalities despite normal visual fields. The aim of this study was to clarify whether patients with coronary heart disease (CHD) have such disturbances in the white-noise field campimetry, too. PATIENTS AND(More)
By microcatheterization of the ophthalmic artery it was possible to test a controlled retinal fibrinolysis in the rabbit. Heparin, tolazoline and urokinase were applied through the microcatheter. By continuous administration of highly diluted fluorescein (0.1%), on-line control of the therapeutic effects was available. Treatment was carried out in cycles of(More)
Purpose: The first morphological changes in eyes with HIV infection are microvascular disease of the retina with cotton-wool spots and microaneurysms. The study was performed to find out if evidence of disturbances of ocular microcirculation can be established by non-invasive methods. Patients and methods: Twenty-seven patients with HIV infection and(More)
The quantitative analysis of the chiral volatile anesthetic isoflurane (1) for biomedical applications by means of enantioselective gas chromatography (mass sensitive detector, selected ion monitoring) was studied. Two methods for the quantification of the enantiomers in blood samples drawn during and after narcosis were compared. Either the isomeric(More)
