Changes in colour discrimination during the menstrual cycle.
2006
A group of normal women of reproductive age were recruited to investigate colour discrimination during the various phases of the menstrual cycle. Colour vision was tested with the Farnsworth-Munsell 100-hue arrangement test, and the test was administered at 3 time points: the beginning of the cycle, ovulation, and the end of the cycle. We found that colour discrimination was better at ovulation than at the other 2 time points. It is possible that psychological as well as hormonal factors could contribute to improved colour vision performance at ovulation.
New iPAD-based test for the detection of color vision deficiencies.
2018
Purpose: To develop and validate a new iPad-based color vision test (Optopad). Methods: A total of 341 student eyes were enrolled in a first comparative study between Optopad and the Isihara tests. In a second comparative study, Optopad vs. the Farnworth-Munsell test (FM 100H), a total of 66 adult eyes were included. Besides the agreement between tests, the correlation between FM 100H and Optopad outcomes were investigated. Multiple regression analysis was used to predict the total error score (TES) from contrast thresholds measured with the Optopad test. Results: The Ishihara and Optopad tests detected the same anomalous patients. Concerning FM 100H vs. Optopad, 10 subjects were diagnosed …
Gaismas avota spektrālā sastāva ietekme uz krāsu redzes deficītu izvērtēšanu ar Farnsworth-Munsell 100 testu

Darbs ir uzrakstīts latviešu valodā uz 25 lapaspusēm. Tas satur 9 attēlus, 3 tabulas, 2 pielikumus un 41 atsauces uz literatūras avotiem. Darba mērķis ir izpētīt, kā gaismas avota spektrālais sastāvs ietekmē Farnsworth-Munsell 100 Hue krāsu sakārtošanas testa (FM-100) rezultātus, un noskaidrot tā nozīmi krāsu redzes diagnostikā. Pētījuma dalībnieki veica šo krāsu sakārtošanas testu 4 dažādu CIE standarta gaismas avotu klātbūtnē – CIE A, CIE D65, CIE F2 un CIE F11. Tika atklāta statistiska nozīmība gaismas avota spektrālā sastāva ietekmei uz FM-100 krāsu sakārtošanas testa S-indeksa vērtību pēc Vingrys & Kingsmith (1988) analīzes metodes, bet ne uz C-indeksa vērtību (p = 0,01).
