INTRODUCTION Based on the knowledge that traumatic brainstem damage often leads to alteration in brainstem functions, including the vestibulo-ocular reflex, the present study is designed to determine whether prediction of outcome in the early phase after severe traumatic brain injury is possible by means of vestibulo-ocular monitoring. METHODS Vestibulo-ocular monitoring is based on video-ocu...

Cat scratch disease is an infectious disease caused by the bacteria Bartonella henselae [1] and is transmitted by cat scratches or exposure to cat saliva. The spectrum of its ocular manifestations includes Parinaud's oculoglandular syndrome, iritis, vitritis, neuroretinitis, panuveitis, retinitis appearing as small white intraretinal infiltrates, and choroidal white lesions [1, 2]. B. henselae ...

The eye movements elicited by auditory stimuli--the audio-ocular response (AOR)--differ from those made in response to a visual target. The movements consist of both monosaccadic and multiple saccadic refixations (MSR). In visual refixation, monosaccadic refixations are always accurate; in AOR, they rarely are. In MSR, many strategies were used in the attempt to find the target but they were no...

The purpose of this study was to evaluate some of the methods used to calculate objective refractions from wavefront aberrations, to determine their applicability for accommodation research. A wavefront analyzer was used to measure the ocular aberrations of 13 emmetropes and 17 myopes at distance, and 4 near target vergences: 2, 3, 4, and 5 D. The accommodative response was calculated using the...

Purpose: to familiarize the public with the role of corneal biomechanics in glaucoma patient management. Methods: Ocular Response Analyzer (ORA) is the only device that measures in vivo corneal biomechanics. Recent studies regarding "corneal biomechanics and glaucoma" were reviewed and the obtained data were compared in order to present a better understanding of the corneal biomechanical proper...

Analysis of vitreous urea nitrogen (VUN) and creatinine (CREA) has been shown to be a useful indicator azotemia in human postmortem examinations. Previous studies cats, dogs, horses, cattle have good correlation between serum ocular fluid for creatinine. The aim this study was evaluate differences VUN, CREA, magnesium (MG) concentrations humor collected from cats that presented with renal or po...

The possibility of the compensation of amplitude and phase errors of data acquisition channels is investigated. The complex passband error can be signiicantly reduced by an appropriate digital lter, as it is illustrated on the example of a dynamic signal analyzer. The aspects of IIR and FIR equalizers are studied: it turns out that for the given anti-aliasing lter (Cauer lter, order 11) an FIR ...
