BACKGROUND: The World Health Organization (WHO) states that visual impairment (VI) is a reduction of vision functions due to eye diseases, trauma, and congenital eye conditions. Current estimates indicate that more than 90% of people with vision impairment live in rural and developing countries. AIM: This study aimed to determine demographic characteristics and causes of visual impairment in the White Nile State of Sudan METHODS: A cross-sectional retrospective hospital-based study, including all patients attending Kosti and Rabak eye hospitals from January to December 2017, was conducted. A total of 1000 records were reviewed, 300 of them met the required criteria and then included in this study, with a mean age of 59.8 ± 18.5 (ranging from 10 to 95) years old. Visual impairment was classified according to the International Classification of Diseases, 11th revision, 2018 (ICD-11). RESULTS: The prevalence of VI was found at 28.5 %. Based on best-corrected visual acuity (BCVA), 6 participants (2.0%) were mild VI, 32 (10.7%) had moderate VI, 152 (50.7%) had severe VI, and 110 (36.7%) were blind. VI was associated with patients' age in children (3.6%) and reached (48.3) in older age (P=0.001). VI was more common among males 158 (52.7%) than females but was statistically not significant (P=0.35). The main causes of VI were cataract (52%), refractive errors (20.7%), glaucoma (16.3%), corneal disorders (5.3%), diabetic retinopathy (1.7 %), and other causes (4%). Conclusion Visual impairment was high in the community and more prevalent among older age. Cataract was the leading cause of VI, then refractive errors and glaucoma. Among children, uncorrected refractive errors and cataracts were the common leading causes of VI. In adults, the main causes were cataracts, uncorrected refractive errors, and glaucoma.

BACKGROUND: Certain occupations and career paths require potential candidates who meet certain visual standards that allow them to apply or hold realistic possibilities for career advancement. AIM: This study aims to assess the visual function requirements for public jobs in Saudi Arabia and compare them with international standards. METHODS: Interview with eye care specialists in the fields of optometry and ophthalmology was conducted. This interview was consisted of seven pre-approved questions on current vision health requirements for eyesight-dependent careers. RESULTS: Interview responses revealed the existence of several visual requirements which were visual acuity, color vision, and visual field. These requirements are essential for various government jobs and functions, with examinations of applicants being necessary for acceptance of a vacancy or subsequent career progression. CONCLUSION: Many government positions of employment require predefined level visual standards which are not widely known. Defining what these standards are and making them publicly accessible will aid both future candidates in better planning their employment options and specialists in providing the required standards on request.

Background: A substantial increase in using digital devices was observed among the population due to staying at home as a result of the quarantine during the coronavirus pandemic. Consequently, ocular symptoms appeared due to spending several hours of screen time per day. Objective: The current study aimed to assess the impact of excessive use of digital devices during the pandemic of coronavirus among the Saudi population. Methods: A community-based cross-sectional study was carried out from November 2020 to January 2021 among the Saudi population. Data were collected by using Ocular Surface Disease Index (OSDI) questionnaires for the assessment of symptoms related to dry eye and their effect on vision. A logistic regression model was used to evaluate the association between the risk factors and the symptoms of dry eye. SPSS 22nd edition was used, any p-value Results: Out of 1573 participants, 93.8% used mobile, 42.4% experienced uncomfortable sensitivity to the light. There were 49.15% of the participants who showed that none of the time they felt blurry vision, 54.8% did not report double vision, and 30.5% who felt a headache recently after quarantine. About 48% of the participants did not have any ocular symptoms, while 52% had dry eye symptoms (mild 22.3%, moderate 13.7%, and severe 15.9%). When the logistic regression model of risk factors associated with severe symptoms of dry eye was applied, wearing a contact lens was the most significant variable (p Conclusion: Dry eye symptoms increased during the quarantine, which indicated that the digital device users need to learn more about the preventive measures from practitioners in eye healthcare. More studies are warranted to assess the impact of digital device usage on all age groups starting from children up to the elderly population.
