This is a prospective randomised controlled trial to assess an intervention of inspection during both phases of colonoscopic examination ( insertion and withdrawal) improve adenoma detecti...
Gastric peristalsis, which occurs during the endoscopic procedure, limits the visual inspection of the inspection field, causing interference in the inspection. The actual endoscopic exami...
A feasibility study to compare the test characteristics of three different oral cancer screening techniques performed by trained primary health care workers:1)Unaided Visual Inspection, 2...
The primary objective is to determine the sensitivity and specificity of the HPV Integration-based cervical screening for detection of high-grade cervical intraepithelial neoplasia (CIN), ...
Small colon polyps which are found during colonoscopy insertion are sometimes difficult to find during withdrawal and thus missed. The investigators aim to evaluate the differences of colo...
To develop an effective, low-cost, single-visit cervical screening strategy incorporating a modified Pap test and visual inspection with acetic acid and Lugol's iodine for low-income settings.
Visual inspection of the instrument channel has been proposed as a quality assurance step during endoscope reprocessing. However, the nature and severity of findings in a broad array of endoscopes (ga...
To assess the prevalence of recently graduated physicians who perceived themselves as adequately competent to perform Papanicolaou (PAP), Visual Inspection with Acetic Acid (VIA), and Visual Inspectio...
Constant improvement in hazard identification is key to personnel safety in workplace. Semantic cues have been proposed to simplify knowledge retrieval for site inspectors in building construction. Ho...
Cervical cancer remains the leading cause of cancer and mortality in low-resource areas with healthcare personnel shortages. Visual inspection is a low-resource alternative method of cervical cancer s...
Reference points located by visual inspection, palpation, or computer assistance, that are useful in localizing structures on or within the human body.
Visual impairments limiting one or more of the basic functions of the eye: visual acuity, dark adaptation, color vision, or peripheral vision. These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions. Visual disability refers to inability of the individual to perform specific visual tasks, such as reading, writing, orientation, or traveling unaided. (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132)
Temporary visual deficit or impaired visual processing occurring in a rapid serial visual presentation task. After a person identifies the first of two visual targets, the ability to detect the second target is impaired for the next few hundred milliseconds. This phenomenon is called attentional blink.
Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.
Repetitive visual hallucinations experienced mostly by elderly with diminished visual acuity or visual field loss, with awareness of the fictional nature of their hallucinations. It is not associated with delusions and other sensory hallucinations.
