SummaryAim: To determine the prevalence of computer vision syndrome (CVS) and ergonomic practices among students in the Faculty of Medical Sciences at The University of the West Indies (UWI), Jamaica. Method:A cross-sectional study was done with a self-administered questionnaire.Results: Four hundred and nine students participated; 78% were females. The mean age was 21.6 years. Neck pain (75.1%), eye strain (67%), shoulder pain (65.5%) and eye burn (61.9%) were the most common CVS symptoms. Dry eyes (26.2%), double vision (28.9%) and blurred vision (51.6%) were the least commonly experienced symptoms.Eye burning (P = .001), eye strain (P = .041) and neck pain (P = .023) were significantly related to level of viewing. Moderate eye burning (55.1%) and double vision (56%) occurred in those who used handheld devices (P = .001 and .007, respectively). Moderate blurred vision was reported in 52% who looked down at the device compared with 14.8% who held it at an angle. Severe eye strain occurred in 63% of those who looked down at a device compared with 21% who kept the device at eye level. Shoulder pain was not related to pattern of use. Conclusion:Ocular symptoms and neck pain were less likely if the device was held just below eye level. There is a high prevalence of Symptoms of CVS amongst university students which could be reduced, in particular neck pain and eye strain and burning, with improved ergonomic practices. | INTRODUCTIONElectronic devices, laptops, tablets, ipads and smartphones, are now an integral part of studying at universities. Smart phone use in education is rapidly developing because of Google, Wikipedia and medical related apps.1-3 Computer vision syndrome (CVS) is at risk of becoming a major public health issue. 4The American Optometric Association defines CVS as a complex of eye and vision problems related to near vision activities involving computer use. 5 The prevalence of CVS ranges from 64% to 90%amongst computer users, with nearly 60 million people affected globally. 6,7 The most frequently occurring health related problems among computer users are CVS, wrist, neck, shoulder and back pain, an over use syndrome resulting in ocular and musculoskeletal discomfort. 8-10Students, who are frequent computer users are at increased risk of CVS and poor posture.

“…Today, VDT use is ubiquitous; therefore, health problems related to the continuous use of VDTs, including ocular diseases, have become a subject of growing concern . VDT use is recognised as an important risk factor for dry eye disease .…”

“…In addition to the standardisation of the diagnostic method, understanding the underlying causes of dry eye disease is important for developing effective prevention and treatment strategies . Although the pathogenesis of dry eye disease associated with the use of VDTs is not fully understood, the use of VDTs is associated with a decreased blink rate and incomplete blinking, leading to tear film instability and dry eye in varying degrees, depending on duration of VDT exposure .…”

Background: To evaluate tear meniscus height and tear meniscus area measured by optical coherence tomography (OCT) and to determine the prevalence of dry eye disease in video display terminal (VDT) users. Methods: This was a case-control study performed on VDT users. The case group consisted of 53 subjects who vocationally use VDT more than six hours per day and the control group consisted of 49 subjects who used VDT not more than one hour per day. The pre-vocational and post-vocational tear meniscus height and tear meniscus area measurements were performed twice in one day using OCT. Tear-film break-up time, Schirmer's test, Ocular Surface Disease Index score and corneal staining score measurements were performed in all subjects. Results: The mean age was 38.9 AE 5.5 years in VDT users and 37.8 AE 5.8 years in the control group (p = 0.426). Twenty patients (37.7 per cent) had dry eye disease in VDT users and five patients (10.2 per cent) had dry eye disease in the control group (p = 0.001). The mean tear meniscus height and tear meniscus area values (pre-vocational and post-vocational) were significantly lower in VDT users than in the control group (p < 0.001, p < 0.001, p = 0.024 and p < 0.001, respectively). The Schirmer's test results, Ocular Surface Disease Index scores, corneal staining scores and tear-film break-up time values revealed significant differences between VDT users and control subjects (p = 0.002, p = 0.006, p < 0.001 and p < 0.001, respectively). In addition, significant correlations were demonstrated between Schirmer's test results, Ocular Surface Disease Index scores, corneal staining scores, tearfilm break-up time measurements, tear meniscus height results and tear meniscus area values. Conclusion: Tear meniscus evaluation using OCT is an effective, non-invasive and sensitive method for detection of dry eye disease in VDT users.

“…1 The continued and unchecked usage has posed a danger to our health and an escalated risk for Computer Vision Syndrome (CVS). 2 CVS is defined as a group of vision, ocular and extra-ocular symptoms which are related to continuous usage of visual display units. Most of these symptoms are related to eye vision, eye muscles, light sensitivity, musculoskeletal system and other general body symptoms.…”

Objectives: Indiscriminate use of computers has increased during the present fast-paced age, and this technology misuse has negatively affected many users. This study aimed to determine the presence of the symptoms of computer vision syndrome and to assess the pattern of computer usage in medical college students. Study Design: Descriptive Cross-sectional study. Settings: Foundation University Medical College, Islamabad, among the MBBS students. Period: From March till August 2018. Material & Methods: A total of 240 conveniently selected medical students took part in this cross-sectional study and filled a pretested self-administered questionnaire, during a six month duration. Ethical consideration was taken, and unwilling students or those with ocular, muscular and general diseases were excluded. Results: A majority of participants 181(75.4%) were females, rest 24.58% were males. The mean age was 21 yrs with SD of 1.6 yrs. A dominant number,170 (70.8%) experienced sore/strained eyes followed by watering of eyes,128 ( 53.3%),and blurred distant vision,121 (50.4%), pain 42.9%,redness 40.8%, dryness 33.8%, blurred near vision 29.2%, burning eyes sensation 42.9%,twitching of eyelids 35%,double vision 24.2%. Headache was experienced by178 ( 74.2%) participants, followed by backache in 137( 57.1%) students, due to overuse of computer(significant at a p value of 0.01).About 62.5% were not using antiglare screens, or frequent blinking method (56.7%) as a means of protection. Conclusion: A majority of the study population had been using computers for less than 5 yrs, giving adequate breaks during the day, yet they were experiencing symptoms of CVS like sore/strained eyes and headache as a consequence of regular computer usage. Most of them were not taking protective measures during computer work.
