Background: Digital devices have been an integral part of our daily lives. With the emergence of COVID-19 pandemic we have gone through strict lockdowns. Most educational institutions conducted classes virtually. This increased the symptoms of digital eye strain. This study aims to assess the prevalence, symptoms, and level of awareness regarding digital eye strain in medical undergraduate students following the COVID-19 pandemic.Methods: Our study was a questionnaire-based cross-sectional study with a duration of 3 months. All the undergraduate medical students studying at Kathmandu Medical College Teaching Hospital were included in the study. A self-administered questionnaire was sent to each student electronically via google forms. Descriptive statistics, frequency tables, and percentages were calculated.Results: A total of 208 students were included in the study. The mean age of participants was 22.7±1.6 years (Mean ± SD) with a mean duration of online classes being11.39 ± 5.2 months (Mean ± SD) . The average screen time of students before the start of online classes was 4.14 (SD=2.13) hours. The average screen time after the start of online classes was 7.93 (SD=2.44) hours, an increase of 91.54%. The overall prevalence of digital eye strain among the respondents was 90.8% (n=189).Conclusions: The prevalence of digital eye strain in our study was high. The average screen time increased significantly following COVID-19. Therefore, it is important to create awareness regarding digital eye strain and practices that decrease the symptoms of digital eye strain. Keywords: COVID- 19; eye strain; medical students.

The use of antimicrobials in animals for growth promotion and infection prevention significantly contributes to the development of antimicrobial resistance (AMR), a growing public health threat. While the World Health Organization (WHO), the United Nations (UN) and the European Union (EU) have taken steps towards reducing and restricting the use of antimicrobials in animals, initiatives are insufficient in developing countries where the demands for food animals continue to rise over the years. The inter-sectoral acknowledgment of inextricable link between animal health, human health and the environment (One Health approach) is critical. Concerted and collaborative efforts among all the stakeholders are essential to deal with this complex problem of resistance.

Background: Inherited macular dystrophies constitute a group of diseases characterized by bilateral central visual loss with symmetrical macular abnormalities usually presenting in the first two decades of life. The aim of this study were to find out the demographic characteristics and disease pattern of inherited retinal dystrophies in subjects attending retina outpatient department in a tertiary care center. Methods: An observational study among twenty-six participants diagnosed as macular dystrophy visiting a tertiary care centre in Nepal, during January 2018 to June 2018 were included in the study. Detailed history, slit lamp examination, dilated fundus examination, coloured fundus photography, full field electroretinogram, multifocal electroretinogram, automated visual field and colour vision were done. Results: A total of 52 eyes of 26 subjects were diagnosed with macular dystrophy. The male to female ratio was 1:1. The mean age of presentation was 28.38 years. Most common symptom was blurring of vision seen in 96.15%.The mean visual acuity was 0.67 log mar units in right eye and 0.71 log mar units in the left eye. The most common macular dystrophy was cone dystrophy followed by adult vitelliform macular dystrophy and Stargardts dystrophy. Conclusions: Cone dystrophy is the most common followed by Stargardt's disease and adult vitelliform macular dystrophy. Most presented in the first two decades of life and the most common presenting symptom was blurring of vision.
