Color Perception Tests: Type of vision test used to determine COLOR VISION DEFECTS.Color Perception: Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary.Color: The visually perceived property of objects created by absorption or reflection of specific wavelengths of light.Speech Discrimination Tests: Tests of the ability to hear and understand speech as determined by scoring the number of words in a word list repeated correctly.Color Vision: Function of the human eye that is used in bright illumination or in daylight (at photopic intensities). Photopic vision is performed by the three types of RETINAL CONE PHOTORECEPTORS with varied peak absorption wavelengths in the color spectrum (from violet to red, 400 - 700 nm).Speech Perception: The process whereby an utterance is decoded into a representation in terms of linguistic units (sequences of phonetic segments which combine to form lexical and grammatical morphemes).Cochlear Implants: Electronic hearing devices typically used for patients with normal outer and middle ear function, but defective inner ear function. In the COCHLEA, the hair cells (HAIR CELLS, VESTIBULAR) may be absent or damaged but there are residual nerve fibers. The device electrically stimulates the COCHLEAR NERVE to create sound sensation.Lighting: The illumination of an environment and the arrangement of lights to achieve an effect or optimal visibility. Its application is in domestic or in public settings and in medical and non-medical environments.Color Vision Defects: Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA). Severity of hereditary defects of color vision depends on the degree of mutation of the ROD OPSINS genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue.Rod-Cone Interaction: Reciprocal action of two vertebrate photoreceptor cells (RODS AND CONES). Rod-cone interaction occurs during MESOPIC VISION in which both rods and cones are active in light transduction to the VISUAL CORTEX. Such interaction can influence visual sensitivity and luminous efficiency.Perception: The process by which the nature and meaning of sensory stimuli are recognized and interpreted.Contrast Sensitivity: The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate visual acuity and to detect eye disease.Photic Stimulation: Investigative technique commonly used during ELECTROENCEPHALOGRAPHY in which a series of bright light flashes or visual patterns are used to elicit brain activity.Psychophysics: The science dealing with the correlation of the physical characteristics of a stimulus, e.g., frequency or intensity, with the response to the stimulus, in order to assess the psychologic factors involved in the relationship.Retinal Cone Photoreceptor Cells: Photosensitive afferent neurons located primarily within the FOVEA CENTRALIS of the MACULA LUTEA. There are three major types of cone cells (red, blue, and green) whose photopigments have different spectral sensitivity curves. Retinal cone cells operate in daylight vision (at photopic intensities) providing color recognition and central visual acuity.Form Perception: The sensory discrimination of a pattern shape or outline.Sensory Thresholds: The minimum amount of stimulus energy necessary to elicit a sensory response.Discrimination (Psychology): Differential response to different stimuli.Light: That portion of the electromagnetic spectrum in the visible, ultraviolet, and infrared range.Visual Cortex: Area of the OCCIPITAL LOBE concerned with the processing of visual information relayed via VISUAL PATHWAYS.Visual Fields: The total area or space visible in a person's peripheral vision with the eye looking straightforward.Ultrasonography, Doppler, Color: Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.Visual Perception: The selecting and organizing of visual stimuli based on the individual's past experience.Hair Color: Color of hair or fur.Motion Perception: The real or apparent movement of objects through the visual field.Social Perception: The perceiving of attributes, characteristics, and behaviors of one's associates or social groups.Depth Perception: Perception of three-dimensionality.Eye Color: Color of the iris.Ophthalmology: A surgical specialty concerned with the structure and function of the eye and the medical and surgical treatment of its defects and diseases.Durable Medical Equipment: Devices which are very resistant to wear and may be used over a long period of time. They include items such as wheelchairs, hospital beds, artificial limbs, etc.Equipment and Supplies: Expendable and nonexpendable equipment, supplies, apparatus, and instruments that are used in diagnostic, surgical, therapeutic, scientific, and experimental procedures.Eye Diseases: Diseases affecting the eye.Equipment and Supplies, Hospital: Any materials used in providing care specifically in the hospital.Ophthalmologic Surgical Procedures: Surgery performed on the eye or any of its parts.Competitive Bidding: Pricing statements presented by more than one party for the purpose of securing a contract.Purchasing, Hospital: Hospital department responsible for the purchasing of supplies and equipment.Medicare Assignment: Concept referring to the standardized fees for services rendered by health care providers, e.g., laboratories and physicians, and reimbursement for those services under Medicare Part B. It includes acceptance by the physician.Orthotic Devices: Apparatus used to support, align, prevent, or correct deformities or to improve the function of movable parts of the body.Optic Neuritis: Inflammation of the optic nerve. Commonly associated conditions include autoimmune disorders such as MULTIPLE SCLEROSIS, infections, and granulomatous diseases. Clinical features include retro-orbital pain that is aggravated by eye movement, loss of color vision, and contrast sensitivity that may progress to severe visual loss, an afferent pupillary defect (Marcus-Gunn pupil), and in some instances optic disc hyperemia and swelling. Inflammation may occur in the portion of the nerve within the globe (neuropapillitis or anterior optic neuritis) or the portion behind the globe (retrobulbar neuritis or posterior optic neuritis).Vision Disorders: 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 (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132).Phenytoin: An anticonvulsant that is used to treat a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs.Miotics: Agents causing contraction of the pupil of the eye. Some sources use the term miotics only for the parasympathomimetics but any drug used to induce miosis is included here.Epilepsy: A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy). (From Adams et al., Principles of Neurology, 6th ed, p313)Optic Nerve: The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.Middle East: The region of southwest Asia and northeastern Africa usually considered as extending from Libya on the west to Afghanistan on the east.

Selective color constancy deficits after circumscribed unilateral brain lesions. (1/224)

The color of an object, when part of a complex scene, is determined not only by its spectral reflectance but also by the colors of all other objects in the scene (von Helmholtz, 1886; Ives, 1912; Land, 1959). By taking global color information into account, the visual system is able to maintain constancy of the color appearance of the object, despite large variations in the light incident on the retina arising from changes in the spectral content of the illuminating light (Hurlbert, 1998; Maloney, 1999). The neural basis of this color constancy is, however, poorly understood. Although there seems to be a prominent role for retinal, cone-specific adaptation mechanisms (von Kries, 1902; Poppel, 1986; Foster and Nascimento, 1994), the contribution of cortical mechanisms to color constancy is still unclear (Land et al., 1983; D'Zmura and Lennie, 1986). We examined the color perception of 27 patients with defined unilateral lesions mainly located in the parieto-temporo-occipital and fronto-parieto-temporal cortex. With a battery of clinical and specially designed color vision tests we tried to detect and differentiate between possible deficits in central color processing. Our results show that color constancy can be selectively impaired after circumscribed unilateral lesions in parieto-temporal cortex of the left or right hemisphere. Five of 27 patients exhibited significant deficits in a color constancy task, but all of the 5 performed well in color discrimination or higher-level visual tasks, such as the association of colors with familiar objects. These results indicate that the computations underlying color constancy are mediated by specialized cortical circuitry, which is independent of the neural substrate for color discrimination and for assigning colors to objects.  (+info)

Preretinopic changes in the colour vision of juvenile diabetics. (2/224)

AIMS: To examine the colour vision of juvenile patients suffering from diabetes mellitus without retinopathy in relation to metabolic and ophthalmic state. METHODS: Metameric matches, both Rayleigh (red/green) and Moreland (blue/green) were used to test the colour vision yearly of 10 juvenile patients. The patients were monitored over 4 years, and during the final year, their blood glucose level was determined directly after testing colour vision. An ophthalmic examination was performed on the day of colour vision testing and blood and urine were analysed regularly throughout the 4 years. Their results are compared with an aged matched control group of 20 subjects, seven of whom were retested after 9-16 months. RESULTS: After 4 years, the colour vision results show an enlarged matching range for the Moreland match, as well as a smaller increase in the matching range for the Rayleigh match. No significant correlation was found between blood glucose at the time of testing and any of the variables measured. CONCLUSION: The pattern of colour vision deficits in metameric matching shown by juvenile diabetics is consistent with postreceptoral alterations of the inner retina, at this preretinopic stage of disease. Duration of diabetes is correlated with both colour vision changes and morphological alteration of the retina.  (+info)

Analysis of red/green color discrimination in subjects with a single X-linked photopigment gene. (3/224)

Many subjects despite having only a single X-linked pigment gene (single-L/M-gene subjects) are able to make chromatic discriminations by Rayleigh matching, especially when large fields are used. We used a combination of psychophysics (Rayleigh match), electroretinograms (ERG), and molecular genetic techniques to rule out several possible explanations of this phenomenon. Use of rods for chromatic discrimination was unlikely since strong adapting fields were employed and the large-field match results were not consistent with rod participation. A putative mid- to long-wavelength photopigment that escapes detection by current molecular genetic analysis was ruled out by finding only a single L/M photopigment in flicker ERGs from 16 single-L/M-gene subjects. Large-field match results were not consistent with participation of S cones. Amino acid sequence polymorphisms in the S-pigment gene that might have shifted the S cone spectrum towards longer wavelengths were not found on sequencing. The mechanism of chromatic discrimination in the presence of a single photopigment therefore remains unknown. Further possible explanations such as variations in cone pigment density and retinal inhomogeneities are discussed.  (+info)

The spatial tuning of color and luminance peripheral vision measured with notch filtered noise masking. (4/224)

We have measured the spatial bandwidths of the bandpass red-green chromatic and luminance mechanisms at four locations in the nasal visual field (0, 10, 20 and 30 degrees) using a method of notch filtered noise masking which effectively removes the artifact of off-frequency looking for our stimuli. Detection thresholds were measured for luminance or isoluminant red-green Gaussian enveloped test gratings of 0.5 cpd embedded in 1/f noise. Firstly, thresholds were obtained as a function of increasing noise spectral density and were fitted using a standard noise masking model. These results support the existence across the visual field of independent, red-green chromatic and luminance mechanisms with similar sampling efficiencies. Secondly, we measured thresholds in notch filtered noise as a function of notch width and derived the spatial bandwidth of the detection mechanism. We find both color and luminance mechanisms have similar bandwidths which remain virtually constant across eccentricity. These results indicate strong overall similarities between the early processing of color and luminance vision, and lend support to the role of color as an 'intrinsic image' in spatial vision. The results are discussed in the light of the anchored channel and shifting channel models of peripheral contrast sensitivity and pattern detection.  (+info)

Evidence for the stochastic independence of the blue-yellow, red-green and luminance detection mechanisms revealed by subthreshold summation. (5/224)

We investigated the manner in which the outputs of the three postreceptoral mechanisms (red-green, blue-yellow and luminance) combine to determine contrast threshold. We used a subthreshold summation paradigm to test whether the combination of the postreceptoral mechanism outputs could be described by a probability summation model which assumes stochastic independence of the mechanisms, and determined the best fitting summation exponent. Stimuli were Gaussian enveloped 1 c/d sinusoidal gratings represented in a 3D cardinal space transformed from cone contrast axes, and normalized to detection threshold. The use of this space avoids the presence of elongated threshold contours, allowing a reliable model fit to include the less sensitive blue-yellow and luminance mechanisms. Our results were well fitted by the probability summation model and hence support the underlying stochastic independence of the three postreceptoral mechanisms.  (+info)

The oblique effect with colour defined motion throughout the visual field. (6/224)

We assessed the extent of the oblique effect (OE) and the meridional orientation effect (MOE) for a chromatic motion task using red/green gratings throughout an 80 degrees visual field. Four different stimulus orientations were tested. Generally, sensitivity to chromatic motion decreased with increasing eccentricity regardless of the visual field meridian. Also, sensitivity was highest for horizontal or vertical gratings, thus supporting the presence of an OE rather than of a MOE. The strength of the OE varied between subjects, but was present from the fovea to 20 degrees of eccentricity. At 40 degrees of eccentricity, chromatic motion was always perceived but the grating orientation did not consistently influence chromatic motion sensitivity. The present study confirmed our previous results on chromatic motion sensitivity and isoluminance ratios throughout the visual field. In addition, our data show that the chromatic system can exhibit OEs at lower spatial frequencies than is observed for the achromatic system.  (+info)

An fMRI version of the Farnsworth-Munsell 100-Hue test reveals multiple color-selective areas in human ventral occipitotemporal cortex. (7/224)

Studies of patients with cerebral achromatopsia have suggested that ventral occipitotemporal cortex is important for color perception. We created a functional magnetic resonance imaging (fMRI) version of a clinical test commonly used to assess achromatopsia, the Farnsworth-Munsell 100-Hue test. The test required normal subjects to use color information in the visual stimulus to perform a color sequencing task. A modification of the test requiring ordering by luminance was used as a control task. Subjects were also imaged as they passively viewed colored stimuli. A limited number of areas responded more to chromatic than achromatic stimulation, including primary visual cortex. Most color-selective activity was concentrated in ventral occipitotemporal cortex. Several areas in ventral cortex were identified. The most posterior, located in posterior fusiform gyrus, corresponded to the area activated by passive viewing of colored stimuli. More anterior and medial color-selective areas were located in the collateral sulcus and fusiform gyrus. These more anterior areas were not identified in previous imaging studies which used passive viewing of colored stimuli, and were most active in our study when visual color information was behaviorally relevant, suggesting that attention influences activity in color-selective areas. The fMRI version of the Farnsworth-Munsell test may be useful in the study of achromatopsia.  (+info)

Colour vision: Is colour constancy real? (8/224)

Colour constancy is typically weaker in the laboratory than it seems in our everyday experience. New measurements using real-world stimuli show that colour constancy is in fact almost perfect, and that several different perceptual mechanisms contribute to achieving it.  (+info)

The value of many histological stains depends on the ability of the observer to differentiate colour. This ability was assessed in 30 histopathologists and cytopathologists of varying experience using the Farnsworth-Munsell 100-hue test. As a group, the pathologists performed better than a reference population. Twenty eight subjects showed a wide ranging ability to differentiate colour: none was colour blind. Three of the 30 pathologists, however, fell below the twentieth centile for normal subjects and only one was aware of this deficiency! They may unknowingly misinterpret subtle stains. Two of these three had specific and major defects which could affect their ability to interpret a wide range of less subtle stains. Those with the poorest colour discrimination were not those with the least experience of microscopy. Pathologists should be apprised of the importance of their ability to discriminate colour, and that formal colour vision testing of prospective histopathologists may be ...
Tuberculosis is a relevant infectious disease in our locality and suspected toxicities with ethambutol is not uncommonly encountered. Currently, patients with suspected ethambutol toxicity are referred to ophthalmology units for screening. Prior to the arrangement of more definitive objective assessments for toxic optic neuropathy like visual field or OCT, subjective tests are use to test for dyschromatopsia since tritan defects are one of the first signs of acquired toxic optic neuropathy[ 10-12]. The Ishihara pseudoisochromatic plates are one of the most commonly used screening tools but as we have demonstrated, the detection rate of dyschromatopisa in 65 with suspected ethambutol toxicity was zero. However, on the same population, the Farnsworth D-15 hue test detected dyschromatopisa in 23.1% of subjects, of which 12.3% were confirmed to have tritan defects compatible with toxic optic neuropathy. We postulate that the suboptimal detection rate in the Ishihara pseudoisochromatic plates is ...

A new web-based colour vision test, Applied Vision Research Centre, Department of Optomery and Visual Science, City University London
The purpose of this study was to evaluate color vision in young patients with demyelinating disease both clinically and electrophysiologically. Thirty young patients (8-28 years, mean age 19 years) with demyelinating disease with or without a history of optic neuritis (ON) were investigated. Color vision was evaluated clinically with the Ishihara test and the Farnsworth-Munsell 100 hue (FM 100 hue) test and electrophysiologically with chromatic visual evoked potentials (cVEPs). Color deficiency axis and error score (ES) obtained with the FM 100 hue test were analyzed. cVEPs to isoluminant red-green (R-G) and blue-yellow (B-Y) stimuli were recorded. The stimulus was a 7 deg circle composed of horizontal sinusoidal gratings with a spatial frequency of ...
The present study explores two hypotheses: a) women during early pregnancy should experience increased color discrimination ability, and b) women during early pregnancy should experience shifts in subjective preference away from images of foods that appear either unripe or spoiled. Both of these hypotheses derive from an adaptive view of pregnancy sickness that proposes the function of pregnancy sickness is to decrease the likelihood of ingestion of foods with toxins or teratogens. Changes to color discrimination could be part of a network of perceptual and physiological defenses (e.g., changes to olfaction, nausea, vomiting) that support such a function. Participants included 13 pregnant women and 18 non-pregnant women. Pregnant women scored significantly higher than non-pregnant controls on the Farnsworth-Munsell (FM) 100 Hue Test, an objective test of color discrimination, although no difference was found between groups in preferences for food images at different stages of ripeness or ...

PURPOSE: To evaluate photopic and mesopic color discrimination in patients with different types of light-filtering intraocular lenses (IOLs).. SETTING: Peking University Third Hospital, Peking University Eye Center, Beijing, China.. METHODS: Cataract patients with different types of IOLs were enrolled 3 months postoperatively. Overall and partial color discrimination under photopic (1000 lux) and mesopic (40 lux) conditions were evaluated with the Farnsworth-Munsell (FM) 100-hue test. Corrected distance visual acuity (CDVA) was tested under both conditions. Subjective visual quality was assessed with the 25-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25).. RESULTS: The study evaluated 43 patients with a blue light filtering IOL (15 photochromic, 13 yellow tinted) or an IOL filtering ultraviolet light only (n = 15). The difference in the FM 100-hue total error scores under photopic or mesopic conditions was not statistically significant between groups. There were no ...

Purpose: Previous studies have shown that patients with type I diabetes can exhibit significant loss of colour vision that often precedes any clinical signs of retinopathy. In this study we investigated loss of red-green (RG) and yellow-blue (YB) chromatic sensitivity in both type I and type II diabetic patients. The aim was to establish how the type, onset, retinal thickness and the glycated haemoglobin (HbA1c) level affect the severity of RG and YB loss.,br /,. Methods: 110 patients diagnosed with diabetes (90 type II and 20 type I) took part in this study. BCVA, duration of diabetes, HbA1c and central subfield thickness (CST) were recorded in each patient. RG and YB colour thresholds were measured monocularly using the CAD (Colour Assessment & Diagnosis) test (Expert Rev. Ophthalmol. 6:409-420, 2011).. Results: Both type I and II diabetic patients showed significant loss of both RG and YB chromatic sensitivity with thresholds that ranged from just above the upper, age-corrected threshold ...

Rea and Freyssinier have developed another index, the Gamut Area Index (GAI), in an attempt to improve over the flaws found in the CRI.[25] They have shown that the GAI is better than the CRI at predicting color discrimination on standardized Farnsworth-Munsell 100 Hue Tests and that GAI is predictive of color saturation.[9] Proponents of using GAI claim that, when used in conjunction with CRI, this method of evaluating color rendering is preferred by test subjects over light sources that have high values of only one measure. Researchers recommend a lower and an upper limit to GAI. Use of LED technology has called for a new way to evaluate color rendering because of the unique spectrum of light created by these technologies. Preliminary tests have shown that the combination of GAI and CRI used together is a preferred method for evaluating color rendering.[26][27] Pousset, Obein & Razet (2010) developed a psychophysical experiment in order to evaluate light quality of LED lightings. It is based ...

All of the volunteers in the study were required to have normal color vision and 20/20 sight.. When the study participants were required to describe colors shown to them across the visual spectrum, the researchers were able to find that the color of men was shifted, thus explaining most mens lack of ability to match clothing and drapes.. The scientists found that men required a slightly longer wavelength to ...
Ive gotten all these great books on jailhouse lawyering from my friend Dana Larsen, who is currently campaigning very seriously for the leadership of the British Columbia New Democratic Party. Its a quixotic campaign centered on Danas sound views on repealing marijuana prohibition. I fear Mike Farnsworth will be the next leader of the BC NDP. Farnsworth is a prohibitionist; he has always parroted the more cops, more laws, more prisons, more punishment mantra that the BC Liberal Party and upstart BC Conservative Party already advocate. The only ideological alternative in the case of Farnsworth taking over the BC NDP leadership would be the BC Green Party, who seem to be poorly led by Jane Sterk, a hard-to-like, prickly matron of a leader who clearly dislikes people and politics, and certainly does little to improve her partys standing with the people of British Columbia. Ineffectual as leader, she may as well be invisible. In the 20 months since the most recent BC provincial election, her ...

Knowledge Transfer (KT) is considered the third mission of a university, along with teaching and research. Traditional KT activities like technology licensing, patenting, contract and collaborative research, and consultancy are well developed and supported by well-established schemes of the University. To broaden the scope of our KT activities, the University has set aside a budget from the UGC Knowledge Transfer Earmarked Fund to support KT initiatives from the College of Business, College of Liberal Arts and Social Sciences and the School of Law. The above scheme, coupled with the Applied Research Grant that supports downstream research, will help to drive the KT development of the University in both science and non-science disciplines ...

Its official: 2015 was the warmest year on record. But those global temperature records only date back to 1850 and become increasingly uncertain the further back you go. Beyond then, were reliant on signs left behind in tree rings, ice cores or rocks. So when was the Earth last warmer than the present?

COMPETENCE My main competence is within applied biospectroscopy and rapid quality assessment of foods. My interests cover front face fluorescence, NIR and Raman spectroscopy. I do also have some experience with spectral imaging, which is a very fascinating and powerful technique. To work efficiently with analysis of spectra from very complex biomaterials, multivariate modelling (chemometrics) is a necessity! I have strong interests in these statistical methods, but at a practical level - they are useful tools. Central applications in my work: · Measurement of auto-oxidation and photo-oxidation in meat, fish and dairy products by fluorescence spectroscopy. · On-line measurement of fat, water, protein, colour and colour defects by NIR andVIS spectroscopy and imaging · Determination of connective tissue in meat and fish by fluorescence spectroscopy · Raman spectroscopy on biomaterials - how to cope with background fluorescence At our institute I am a principal researcher and project manager for ...

Why normal cells turn into cancer cells? One of the factors is deeply related to the failure of the cell differentiation mechanism called DNA methylation. The joint research groups of The Institute of Medical Science, the University of Tokyo, Yokohama City University, and Center for Integrated Protein Science Munich (CIPSM) have clarified new mechanism for controlling DNA methylation in cells. Ubiquitination of a protein called PAF15 is an important factor for the inheritance of DNA methylation, according to the new research.

As a test engineer with Medtronic, Nick Nagel 14 is saving lives by testing medical devices before they ever come in contact with patients. For Nagel, every test, every data point, is crucial. "Testing helps us better understand why something performs as it was intended to, or may fail or stop working," he said. "My job has a direct affect on patients, so the device needs to work the way its supposed to work every time." For example, the Andover, Minn., native is currently testing ablation catheters, which doctors use on patients to interrupt unwanted electrical pathways in the heart. Read more › ...

To compare chromatic VEP response to isoluminant red-green stimulus in children with congenital red-green color deficiency with a control group of 30 children with normal color vision. 10 children (8-16 years) with congenital color vision deficiency (7 in deutan and 3 in protan axis) and 30 healthy children (7-19 years) were included in the study. Color vision was assessed with Ishihara plates, Farnsworth-Munsell hue 100 test and Farnsworth-Munsell D-15 test. VEP to isoluminant red-green stimulus were recorded. Isoluminant point was determined for each child subjectively by using heterochromatic flicker photometry, and objectively from recordings. The stimulus was a 7 deg large circle composed of horizontal sinusoidal gratings, with spatial frequency 2 cycles/deg and 90 % contrast. VEP were recorded from Oz (mid occipital) position. Children were tested binocularly. The properties (latency and amplitude) of the negative and positive wave were analyzed. Results were compared between the two ...
Whats it like to be color blind? Contrary to what the name implies, color blindness usually does not actually mean that you dont see any color, but rather that you have difficulty perceiving or distinguishing between certain colors. This is why many prefer the term color vision deficiency or CVD to describe the condition. CVD affects men more than women, appearing in approximately 8% of men (1 in 12) and .5% of women (1 in 200) worldwide. Having color vision deficiency means that you perceive color in a more limited way than those with normal color vision. This ranges from mild, in which you may not even be aware that you are experiencing color differently, to severe, which is perhaps the more appropriate from to be called "color blind" and involves the inability to see certain colors. CVD can be inherited; it is caused by abnormalities in the genes that produce photopigments located in the cone cells in your eyes. The eyes contain different cone cells that fire in response to a specific ...
Already John Dalton wrote about his color vision deficiency. Red, orange, yellow, and green all appeared to be the same color to him. The rest of the color spectrum seemed to be blue, gradually changing to purple. Dalton concluded already in the year 1798, that he can not see long wavelength red light-known as protanopia today.. Some recent genetic analysis of Daltons preserved eyes showed, that he was suffering from deuteranopia-another form of red-green color blindness. But anyway this is the first description of the red-green color vision deficiency.. In 1837 August Seebeck carried out some systematic color vision tests and found two different classes of red-green color blindness with differences in severity from weak to strong in both classes.. After that investigations started to gather more details and scientists learned a lot more about our color vision: The genetic source of color vision, its deficiencies and the precise knowledge about the mechanism of color vision in our eyes.. ...
Most people with color vision deficiency can still see colors, but will have difficulty differentiating between shades of reds and greens (more common), or between blues and yellows (less common).. During a comprehensive eye exam, our Optometrists test for signs of color deficiency. This is done with the use of pseudoisochromatic plates - pictures composed of colored dots arranged to form numbers or shapes. You will be asked to differentiate between the number seen from the adjacent colored dots. If no number is visible, you have a deficiency in the color used in that plate.. ...

Color Vision Deficiency Eight out of every one hundred men and one out of every two hundred women, or 8% of men and .5% of women, has a color vision
Individuals with Color Vision Deficiency (CVD) are often unable to distinguish between colors that individuals without CVD can distinguish. Recoloring tools exist that modify the colors in an image so they are more easily distinguishable for those with CVD. These tools use models of color differentiation that rely on many assumptions about the environment and user. However, these assumptions rarely hold in real-world use cases, leading to incorrect color modification by recoloring tools. In this doctoral symposium, I will present Situation- Specific Models (SSMs) as a solution to this problem. SSMs are color differentiation models created in-situ via a calibration procedure. This calibration procedure captures the exact color differentiation abilities of the user, allowing a color differentiation model to be created that fits the user and his/her environmental situation. An SSM-based recoloring tool will be able to provide recolored images that most accurately reflect the color differentiation ...
Assistive software that recolors images for individuals with color vision deficiency relies on models of the color differentiation abilities of its intended users. Situation-specific models address the shortcomings of current assumption-based models by using in-situ calibration to capture the color differentiation abilities of a specific user in a specific environment. However, this calibration procedure is time consuming, and when the user is unable to perform it, the assistive software fails to recolor properly. To address this problem, we propose a collection of situation-specific models--Multiple Model Aggregation (MMA)--that can be used to instantly provide the best previously-generated model to the assistive software with no input required from the user. Design challenges for extending MMA to any model-based system are also presented.. ...
Besides red-green color blindness, which is encoded on the x-chromosome (sex-linked) and therefore much more common for men, there are also forms of color vision deficiency which are evenly distributed between male and female like Tritanomaly (blue-weakness) or Tritanopia (blue-blindness) and the real color blindness Achromatopsia (monochromacy) or the so called blue-cone monochromacy (only blue cones).. Color blindness simulation is fascinating! If you are not colorblind it is so hard to imagine what it looks like to be colorblind: Which color do you see? Do you see any at all? What does it mean not to be able to see red? and so on. My COlor BLIndness Simulator is a handy tool which allows you to use your own images and try out all the different simulation types. It is even possible to save any simulated image and have a one-by-one comparison.. Online color blindness testing is often done but unfortunately no yet as good as it could be. Usually youll find out about color blindness at school or ...
