Disease relevance of Asthenopia


High impact information on Asthenopia

  • The consequences of high temporal frequency visual stimuli delivered by ubiquitous video screens on epilepsy, headaches, and eyestrain must be considered [2].
  • METHODS: All living patients in the Oslo RA Register area received a postal questionnaire in 1994 and 2001, including the Arthritis Impact Measurement Scales 2 (AIMS2), Short Form-36, the modified Health Assessment Questionnaire, and pain and fatigue visual analogue scales (VAS) [3].
  • The results suggest that taurine supplementation alleviates visual fatigue induced by VDT work [4].
  • METHOD: 722 VDT workers (242 subject workers with symptoms of asthenopia and 480 controls without such symptoms) without obvious organic ocular diseases received an ophthalmological examination consisting of refractometry and a tear function (phenol red thread) test [5].
  • METHODS: 16 eyes of 8 myopia cases whose muscular asthenopia was corrected by subjectively accepted triangular prism after PRK with vision more than 0.8 were followed up for 6-14 months [6].

Chemical compound and disease context of Asthenopia

  • The therapeutic administration of pyridostigmine improved static measurements of accommodation and vergence and reduced asthenopia [7].

Gene context of Asthenopia

  • The occurrence of visual fatigue due to 4-hr VDT operation was also confirmed by CFF measurements and reported subjective visual symptoms in this experiment [8].
  • Even with the same complaint of eyestrain, it was concluded that VDU work produced abnormalities 1.8 times higher in the near triad produced by tonic stimulus [9].
