Purpose: To estimate the prevalence of computer vision syndrome and evaluate the effects of interventions applied to computer users in a tertiary care hospital. Materials and Methods: In our study, 102 eyes of 51 people (non-medicos) with desk job using computers/mobile were taken as the study group. The Schirmer test, tear breakup time (TBUT) and ocular surface disease index (OSDI) were evaluated. Accordingly, they were given treatment and followed up. Results: In our study, we included 51 subjects who were a regular user of mobile and computers. Mean screen time was 6.08 ± 1.5 hours. Before treatment, the mean Schirmer’s, TBUT and OSDI test were 8.85 ± 1.2 mm (range 5.5–11.5 mm), 7.64 ± 2.4 seconds (range 4.0–12.5 seconds) and 30.47 ± 13.1 (range 10.40–62.50), respectively. The prevalence of dry eye was 58%, according to OSDI severity grading. After treatment, the Schirmer1, TBUT and OSDI tests showed improvement and the results were highly significant (p < 0.001). Conclusions: It is important to optimize the exposure time and improve awareness among users. Its high time now, every institution should come up with a few guidelines in concern with the high screen time of the desk job worker.
Introduction: To study the incidence, visual outcomes, andanterior segment anatomical outcomes of intraoperativecomplications of cataract surgery.Materials and Methods: This is a prospective observationalhospital-based study conducted in the department ofOphthalmology SRMS IMS, Bareilly, Uttar Pradesh. Inthis study, 70 patients were studied for 1.5 yrs from 1st ofNovember 2019 to 13th of April 2021. All these patients withintraoperative complications were evaluated preoperatively andpost-operatively for vision and anterior segment anatomicaloutcomes.Results: In this study, the commonest intraoperativecomplication was Injury to Iris/ Iridodialysis (52.9%). Basedon pre-operative vision, the patients had 5/60 and 6/36 visionwith 30.0%, each followed by 6/24 (14.3%) and 3/60 (12.9%).Corneal hazy/edema was reduced to 10.0% at one-monthfollow-up from 52.9% on post-operative day one. Also, DMfolds were reduced to 11.4% from 75.7% at day one.Conclusions: In this study, visual outcome of the cataractsurgery was much better, and there is a significant progressionin the visual acuity. Routine monitoring of the visual outcomeof the cataract surgery at each hospital would go in long-wayto enhance both the quantity and quality of the surgery andthus decrease the substantial amount of burden of blindnesson our country.
The paper provides a solution to create a method to recognize hand gestures and control music player using pattern recognition technique. It does not involve the use of any other hardware except computer equipped webcam.Hand can be used as an input device and by making its gesture understandable to computer, the music player can be controlled. The functionality is a detection mode developed to capture hand gestures and trigger event of interests,such as windows media player.Gesture Recognition uses MATLAB to emphasize on easy and swift communication using minimum tools which can be easily accessible which leads to reduction in time consumption and error scope as well as the easy operation of the system.
