Prism adaptation has been shown to successfully alleviate symptoms of hemispatial neglect, yet the underlying mechanism is still poorly understood. In this study, the antisaccade task was used to measure the effects of prism adaptation on spatial attention in healthy participants. Results indicated that prism adaptation did not influence the saccade latencies or antisaccade errors, both strong ...

PURPOSE To determine the relative binocular signal strength of moving images that are peripherally viewed through a monocular field expansion prism as opposed to moving images viewed directly. We hypothesised that prism blur might make prism images predominate less than images viewed directly with the other eye. METHODS We employed the binocular rivalry paradigm to measure the relative binocu...

BACKGROUND Compare Goldmann applanation tonometer (GAT) prism and correcting applanation tonometry surface (CATS) prism to intracameral intraocular pressure (IOP), in vivo and in vitro. METHODS Pressure transducer intracameral IOP was measured on fifty-eight (58) eyes undergoing cataract surgery and the IOP was modulated manometrically to 10, 20, and 40 mmHg. Simultaneously, IOP was measured ...

Three monkeys performed a visually guided reach-touch task with and without laterally displacing prisms. The prisms offset the normally aligned gaze/reach and subsequent touch. Naive monkeys showed adaptation, such that on repeated prism trials the gaze-reach angle widened and touches hit nearer the target. On the first subsequent no-prism trial the monkeys exhibited an aftereffect, such that t...

Abstract Background The facilities for intensive care are improving day by in all departments including pediatrics, and prognostication has always been the duty of a physician. Scoring systems useful to objectively measure severity predict prognosis sick children. This study was done assess illness mortality risk using PRISM score children aged 1 month–18 years, admitted into pediatric unit ter...

Vertical fusional vergence (VFV) normally compensates for slight vertical heterophorias. We employed magnetic resonance imaging to clarify extraocular muscle contributions to VFV induced by monocular two-prism diopter (1.15°) base-up prism in 14 normal adults. Fusion during prism viewing requires monocular infraduction. Scans were repeated without prism, and with prism shifted contralaterally. ...

PURPOSE To evaluate the effect of acrylic refractive prism and Fresnel membrane prism on stereoacuity in intermittent exotropia. MATERIALS AND METHODS Stereoacuities of fifty-two patients (mean age, 12.4 years; range 6 to 45 years) with intermittent exotropia were measured using the Titmus and TNO stereotests, while they wore prisms of varying power on nonfixating eye or evenly on each eye. ...

objective critical illness polyneuropathy and myopathy (cipnm) is a major complication of severe critical illness. previous studies have suggested that many risk factors such as sepsis, multiorgan failure, and neuromuscular blocking agents play a role in cipnm pathogenesis. the aim of this study was to evaluate possible risk factors in the development of cipnm in a pediatric intensive care unit...

A recent emergence of small, resource-constrained, and highlymobile computing platforms presents numerous new challenges for software developers. We refer to development in this new setting as programming-in-thesmall-and-many (Prism). This paper provides a description and evaluation of a middleware intended to support software architecture-based development in the Prism setting. The middleware,...
