Computer vision syndrome (CVS) is a combination of eye and vision problems associated with the use of digital devices. CVS affects the eyesight, visual comfort and occupational productivity of workers due to the different symptoms computer users and staff experience: ocular discomfort, headache, dry eye, blurred vision etc. Aim of the study: To assess the symptoms of CVS in a software company in Varna by subjective and objective tests and prescribe measures for prevention. Materials and methods: 40 participants-31 men and 9 women were distributed with a valid questionnaire regarding common symptoms of CVS. The group was tested with the Schirmer test to measure the tear film quantity. Participants have passed a medical exam by an ophthalmologist before the study. Results: - 11 or 27,5% of the participants in the questionnaire have reached score ≥6 – have CVS - 10 or 25 % of the participants in the Schirmer test have reached results < 5mm. in the tear strip - The gender distribution shows 3 women (33.33%) and 8(25.8%) of men have CVS by questionnaire study and 3(33.33%) of women and 7(22.6%) of men based on Schirmer test have dry eye as asymptom of CVS. Conclusion: The results of the study predispose to further evaluation and tracking of the symptoms of CVS among this occupational group. All of the participants are aware of Ordinance № 7 related to health and safety work conditions with VDT’s and received information regarding the physiological work-rest regime. Occupational risk of CVS can be reduced with early diagnose, assessment and prevention of the symptoms.

In the present era, the full computerization of a country is necessary for the progress. The present era can be defined as “Computer Age”. It has seems that the work at the computer is very intensive & most tiring therefore countries like Germany has included computer operational work in the list of the 40 most harmful trades for the health & restricted work at the computer should not exceed 50% of the working time. In the developing countries like India where the remuneration for the work is far from satisfactory & the young generation is aspiring for more material gains which necessitate them to work overtime or have part-time jobs in addition to their legitimate work. This situation adds up to the works with the computer which badly affects their health. Computer Vision Syndrome (CVS) is the complex of eye and vision problems related to near work which are experienced during or related to computer use. CVS is characterized by visual symptoms which result from interaction with a computer display or its environment. In most cases, symptoms occur because the visual demands of the task exceed the visual abilities of the individual to comfortably perform the task. In CVS following Signs & Symptoms occurs.they are Presence of excessive debris & mucous strands in the tear film., Reduced or absence of marginal tear strip.Lusterless ocular surface - xerosis.,Lid Dry & Rough touch. And Symptoms are Itching, Burning sensation, Blurred vision, Dryness of eyes, Redness of eyes, Pricking Pain. , Foreign body Sensation, Difficulty in opening & closing the lids.For the study, we have taken Triphala Ghrita Tarpan for 7 days in three consecutive months for 30 patients in treated group and in controlled group eye exercises given like palming, eye movements for 7days in three consecutive months for 30 patients.The results are very much satisfactory in the treated group as compared to the controlled group.The details will be given in detail in full research paper.

Dry Eye Symptoms

Background: Global estimates suggest that nearly 60 million people suffer from Computer Vision Syndrome (CVS).Aim: The goal of this research was to evaluate the effectiveness of an educational intervention using the 20/20/20 rule to reduce CVS symptoms.Setting: The study was conducted in the Qassim University eye clinic.Methods: An experiential intervention study was conducted amongst 40 patients with CVS, with their age ranging from 21 to 38 years. The sample was divided into two groups: (1) intervention patients (n = 20), who were given a structured advice booklet about how to reduce CVS symptoms using the 20/20/20 rule, and (2) control (n = 20) with CVS, who were given advice to simply drink more water. Both groups completed two questionnaires, namely, the CVS-Q and Dry Eye Questionnaire-5 (DEQ-5). Dry eye clinical tests were performed. The same procedures were repeated after 20 days to compare the outcomes before and after intervention.Results: The study findings revealed that patients complaining from dry eye symptoms showed significant changes after the educational intervention (pre-intervention: 9.05 ± 4.32; post-intervention: 7.10 ± 3.61) (p = 0.04). The symptoms of CVS were slightly reduced after educational intervention, from 9.00 ± 3.03 to 8.35 ± 1.89 (p = 0.38). However, TBUT showed a significant increase after the educational intervention (pre-intervention: 6.20 ± 2.02 s; post-intervention: 8.55 ± 2.84 s) (p = 0.005).Conclusion: The educational intervention of the 20/20/20 rule induces significant changes in dry eye symptoms and tear film and some limited changes for ocular surface integrity.

Abstract Purpose Dry eye symptoms after conventional cataract surgery are a very common problem. Until now, only few data are available on objective tear film parameters in regard to femtosecond laser-assisted cataract surgery (LCS). Aim of this study was therefore to analyze and compare tear film parameter changes between LCS and conventional cataract surgery. Methods A consecutive group of 34 patients, scheduled for cataract surgery, were randomly selected for either LCS or conventional cataract surgery (17 patients/group). Tear film assessments including tear film osmolarity, Schirmer test, MMP-9 analysis via quantitative ELISA, corneal sensitivity, corneal fluorescein staining, and conjunctival fluorescein staining were sequentially evaluated pre- as well as 1 and 3 months postoperatively. Results Both groups showed no significant difference in baseline characteristics. All surgeries were performed without any complications. After 1 and 3 months, there was no statistically significant difference in regard to tear film osmolarity (1 month: p = 0.81, 3 months: p = 1.0), Schirmer test (1 month: p = 0.35, 3 month: p = 0.08), and MMP-9 concentration (1 month: p = 0.36, 3 month: p = 0.28) between the two groups. Conclusions Neither LCS nor conventional cataract surgery affected objective tear film parameters significantly during our 3-month postoperative observation period. Hence, both surgical techniques can be equally used to treat patients without prior dry eye symptoms.

Background: Computers and other visual display devices have become essential in the present era and have led to a rise in computer-related health problems. Using computers in homes, universities and other institutions has increased output greatly but has also led to an increased risk of developing Computer vision syndrome (CVS). Objectives: To determine the prevalence and risk factors associated with computer vision syndrome among undergraduates. Methodology: A cross-sectional study was conducted among153 respondents who were selected using a multi-stage sampling technique. A pretested, structured, interviewer-administered questionnaire was used to collect data. SPSS version 23 was used to analyze the data. A Chi-square test was used to determine the relationship between CVS and associated risk factors at a P-value of <0.05. Results: The mean age of respondents was 22.4 ± 3.4 years. The prevalence of CVS in this study was 83 (54.3%). The common symptoms experienced among the respondents were headache (51, 61.4%), eye strain (48, 57.8%) and blurred vision (42, 50.6%). The risk factors significantly associated with CVS in this study were duration of computer use, hours of computer use per day, level of a computer screen and taking breaks during computer use. Conclusion: About half of the students in this study had at least one symptom of CVS. Therefore, awareness of CVS should be created by the institution during which students would be educated on CVS and its prevention.

Introduction: Dry Eye Syndrome (DES) is a multifactorial disease of the eye characterized by loss of homeostasis from the tear film and is accompanied by ocular symptoms. One of many factors that can cause DES is the use of contact lenses. This research was conducted to determine the relationship of water content in contact lenses with the occurrence of DES. Methods: This research was conducted in 2019 with a cross-sectional study design with the Tear Break Up Time (TBUT) test, Schirmer test and questionnaire. The research respondents were students of Atma Jaya School of Medicine and Health Sciences (FKIK UAJ) whose eyes were examined as samples (n = 84). The water content of the respondent's contact lenses was obtained using a questionnaire. The inspection methods used to determine DES are TBUT test and Schirmer test. Data analysis using chi-square test with significance level of p <0.05. Results: The prevalence of DES obtained in students with a water content <50% is 25.9%, while the DES in students with a water content >50% is 25.5% . Conclusion: There is no significant relationship between water content in contact lenses with the occurrence of DES in FKIK UAJ students (p=0.963).

Abstract Background Computer vision syndrome is a multi-factorial condition of the eye that results in symptoms of stress and discomfort among computer users. It causes chronic vision-related morbidity and reduced work productivity. Ninety percent and 75% of computer users globally and in Africa respectively suffer from CVS. It is an insidious chronic condition that however, has hitherto received little attention, both by health providers as well as computer users. Also, it is likely to be under diagnosed as it mimics other eye conditions. The risk factors for CVS include prolonged period of electronic device use and glare. In Kenya, lack of awareness of the disease is a key barrier to early detection, health seeking and use of interventions. The burden of CVS and how much computer users in learning institutions are aware of and perceive CVS remains unknown.Methods This study adopted cross-sectional study design to determine the level of awareness, perception of CVS, uptake of preventive measures by students at Maseno University. In total, we administered questionnaires to 384 randomly selected students.Results The mean age was 19.5 years (SD= 0.747) with 18-24 years as the modal age group. Females comprised 51.3% (n=197) and males 48.7%. Participants who had at least 5 symptoms of CVS were 60.4% (n= 232). Awareness level was classified as low in 47.8%; medium level in 38.2% and high level in 13.8% of respondents . Sixty percent of respondents did not perceive CVS as an issue of public health concern compared to 39.8% who perceived CVS as an issue of public health concern ( p=0.001). In terms of precautionary measures, only duration of computer use (46.2%, p = 0.001 ) were practiced. The study results show that at least 3 out of 5 students have at least five symptoms of CVS, whereas awareness of the disease and related risks remain low.Conclusion The results of the present study indicate that CVS is a less recognized health concern among university students. Consequently, screening for the disease sensitization of students on CVS and awareness campaigns to improve early recognition and diagnosis of disease as well as uptake of interventions is recommended.

Sjögren‘S Syndrome

Introduction: To measure corneal layers’ light reflectance (LR) in eyes affected by dry eye disease caused by Sjögren's syndrome (SSDE) with corneal confocal microscopy (IVCM) and to study the correlations with tear film tests. Materials and Methods: Thirty-six patients affected by SSDE and 36 healthy subjects (HS) were enrolled in this retrospective study, participants of both groups were age and sex matched. Each study participants had a complete eye visit and break up time (BUT), Schirmer test, with and without stimulation, at the end of the visit an IVCM scan was performed. LR measured by IVCM at Bowman membrane (BM) level and at 50 µm, at 100 µm and at 200 µm deeper was compared in the two groups of participants. The correlations between LR measurements and tear film test results were investigated. Results: In SSDE eyes, LR was significantly higher (p<0.001) in SSDE patients at BM level (+14.43 ± 3.27 LRU) and also in the other levels evaluated, compared with HP. Good correlations were observed between LR values at BM and Schirmer test ones with (r = -0.82) and without (r= -0.81) stimulation and BUT (r= 0.80) in SSDE eyes. Correlations values were Adecreasing the deeper corneal layers. Conclusion: Even if need to be verified in further studies with a larger population, results obtained in this study suggest that IVCM could be an interesting and effective tool in evaluating the SSDE patients and it could be adopted by physicians’ community because it seems very promising.
