Long working hours with video display unit without appropriate breaks could drain the eyes. This study intends to investigate the efficiency of eye rest-break application to reduce dried eye symptoms by increasing blink rates. Blink rates and dried eye symptoms score among laboratory workers before and after the implementation of eye rest-break application were compared. The numbers of blink rates were recorded using a webcam for 5 minutes without the subjects aware when the recording starts or ends. Then, the Ocular Surface Disease Index (OSDI) was used to measure the dried eye symptoms. For eyes rest-break, EyeLeo© application was used. It is computer application that gives reminders to video display unit (VDU) users to take short breaks for their eyes. Six laboratory workers who are constantly working with VDU were selected as subjects. Data was analysed using Wilcoxon Signed-Rank Test, to test the comparison between variables before and after intervention by reporting its median (inter quartile range, IQR). The findings showed that the median after intervention (39.5, 10) is significantly higher (p-value = 0.028) than the median before intervention (7.3, 3). As for dried eye symptoms, median for Ocular Surface Disease Index after intervention (27.9, 8.9) is significantly lower (p-value = 0.027) than the median before intervention (36.5, 9.4). As a conclusion, application such as EyeLeo© eye rest-break is a potential intervention and may be used to increase blink rates and reducing dried eye symptoms among visual display unit workers.

Objective: To determine the frequency of ocular surface disease among patients with open angle glaucoma using topical antiglaucoma medications presenting at a tertiary care eye hospital. Study Design: Cross-sectional analytical study. Place and Duration of Study: Armed Forces Institute of Ophthalmology, Rawalpindi, from May 2019 to Jan 2020. Methodology: One hundred and eighty patients aged 18 or more, with open angle glaucoma using any of the topical antiglaucoma medications including preparations of dorzolamide, brimonidine, timolol, levobunolol, betaxolol, latanoprost, travoprost, bimatoprost or a combination of these for more than six months took part in the study. Ocular surface disease index was used to assess the presence and severity of ocular surface disease. Results: Out of 180 patients of glaucoma managed with topical anti-glaucoma medications, 83 (46.1%) did not show presence of ocular surface disease when ocular surface disease index was administered. Twenty-nine (16.1%) patients had mild symptoms, 17 (9.4%) had moderate symptoms while 51 (28.3%) patients reported severe symptoms of ocular surface disease. Advancing age and longer duration of treatment with topical anti-glaucoma medications had statistically significant association with the presence of ocular surface disease (p-value <0.05). Conclusion: Presence of ocular surface disease was a common finding among patients using topical agents for the management of glaucoma. Advancing age and prolonged use of anti-glaucoma medication emerged as risk factors statistically related to the presence of ocular surface disease.

This paper discusses an experience of training in ergonomic work analysis (EWA). Two ergonomists of the National Institute for Research on Working Conditions (INRCT, in French) trained a group of employees in the Brussels plant of a multinational company. This training took place after having checked about fifty VDU (video display unit) workplaces. None of these 50 VDU users was aware of the possibilities of adjusting his or her specific workplace. The manager and the union decided to train one or two persons in each department, to enable them to answer minor questions of their unit's employees relating to adjusting their own workplace. It was agreed that more difficult problems raised by the employees would be transferred to external experts. The paper seeks to analyse the impact of this experience on the VDU workers: are they able to change their working conditions? What exactly did change? To conclude, some conditions necessary for the success of such training programmes are highlighted.

A method is described for the non-destructive, non-invasive, detection of shell lesions in the New Zealand paua, a marine gastropod Haliotis iris using diagnostic radiology. The X-ray method reliably detected the presence of shell lesions in 96% of the cases examined once lesion dimensions exceeded 6.2 × 7.1 mm. The extent of lesions above this size can be reliably and accurately determined from X-ray images viewed on a video display unit (VDU). Biofouling on the outside of the shell can cause misdiagnoses. This method is a significant animal welfare refinement in the identification of marine gastropods with shell lesions, when compared with traditional techniques which kill the animals.
