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 ...

This request should be in writing and should be directed to the Aerospace Medical Certification Division or the appropriate regional flight surgeon. If the applicant passes the signal light test, the FAA will issue a medical certificate without the color vision limitation and provide the applicant with a "letter of evidence." The signal light test may be given any time during flight training. ...
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 ...

While others have chronicled the life and times of P.T. Farnsworth, my interest lies in his inventions and patents. More specifically, how the design of those separate devices led up to the final development of the Fusor - the only fusion reactor ever designed and operated at better than break-even efficiency! Farnsworths Fusor produced neutron counts measured in the billions-per-second. . No other fusion device built, even 30 years later can match this performance. It is unfortunate that Farnsworth died before perfecting the device into a commercial product, but that does not detract from his accomplishment in the least. That one man could conceive of and design a working fusion reactor is a phenomenal personal achievement. It would be nice if someone would build another working device ...

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 ...

Purpose: To describe in detail the phenotype of CORD5 in two families segregating a mutation c.1878G , C (p.Q626H) in the PITPNM3 gene. Methods: The study included 35 individuals from two different families of Swedish origin, all heterozygous for a PITPNM3 p.Q626H mutation. All participants underwent ophthalmological examination including kinetic perimetry, and in selected cases adaptometry, colour vision tests and optical coherence tomography (OCT). Electrophysiological studies were also performed. In some cases, the data were obtained from medical records. Results: The majority of patients showed subnormal visual acuity and light sensitivity from childhood. Early signs of macular degeneration were also observed. There was a progressive decrease in visual acuity leading to legal blindness in early adulthood. Electrophysiological testing showed a progressive loss of photoreceptor function restricted mainly to the cones. OCT revealed decreased macular thickness with flattened and enlarged fovea. ...

Lee Rannals for redOrbit.com - Your Universe Online. Scientists have finally confirmed what most have already known for generations and generations, men and women see things differently.. Scientists reported in the journal Biology of Sex Differences that men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.. Researchers from Brooklyn and Hunter Colleges of the City University of New York compared the vision of men and women at the age of 16 and older from college and high school, including students and faculty. 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 ...
