Computer and visual display terminals (VDT) vision syndrome (CVDTS)

Abstract

m e d i c a l j o u r n a l a r m e d f o r c e s i n d i a 7 2 ( 2 0 1 6 ) 2 7 0 -2 7 6 a r t i c l e i n f o The use of these devices has made our life simple in household work as well as in offices.However the prolonged use of these devices is not without any complication. Computer and visual display terminals syndrome is a constellation of symptoms ocular as well as extraocular associated with prolonged use of visual display terminals. This syndrome is gaining importance in this modern era because of the widespread use of technologies in day-to-day life. It is associated with asthenopic symptoms, visual blurring, dry eyes, musculoskeletal symptoms such as neck pain, back pain, shoulder pain, carpal tunnel syndrome, psychosocial factors, venous thromboembolism, shoulder tendonitis, and elbow epicondylitis. Proper identification of symptoms and causative factors are necessary for the accurate diagnosis and management. This article focuses on the various aspects of the computer vision display terminals syndrome described in the previous literature. Further research is needed for the better understanding of the complex pathophysiology and management. #

Visualization of the distribution of anthocyanin species in mice eyeball by matrix‐assisted laser desorption/ionization mass spectrometry imaging

“…Eyestrain is thought to be caused by various issues, one of them being eye fatigue due to tension of the extraocular muscles. Specifically, it is thought that continual focus on an electronic device, such as a computer or a television, at the same distance and for a long time, causes muscle tension and, ultimately, fatigue . The anthocyanin species localized in the muscle tissue with the eyeball might be responsible for the relief of eyestrain by promoting the relaxation action of external eye muscles.…”

Monoglucosyl rutin facilitates recovery from eyestrain in visual display terminal users: a randomized, placebo-controlled, double-blind, crossover study

“…In particular, the number of smartphone users constantly grows worldwide. The increasing use of computers and their related output devices causes a clinical condition called computer vision syndrome [1]. Computer vision syndrome includes extraocular symptoms, which involve the musculoskeletal system, peripheral nervous system, and skin.…”

“…Using VDTs involves a prolonged near-vision task, but the symptoms associated with their use, such as blur, dryness, and eyestrain, are significantly more severe than those associated with similar tasks without using VDTs. VDT use causes eyestrain, stiffness of the shoulder and neck, and therefore, leads to a lower quality of life (QOL) [1][2][3][4]. VDT use also induces oxidative stress and excessive activation of the autonomic nervous system [5].…”

Amelioration of Visual Display Terminal-induced Ocular Fatigue by Aqueous Extracts of <i>Perilla frutescens </i>var. acuta

“…Eye fatigue has been steadily increasing in recent years, with the growing use of visual display terminals (VDT) such as computers and smartphones [1,2,3]. The symptoms of eye fatigue include ocular pain, dry eye sensation, headache, dizziness, ghost images, eye pain, dryness, heavy eyelids, and blurred vision [4,5].…”
