Background: Night blindness is a visual disorder associated with unusual vision during the night or in darkness. Vitamin A deficiency (VAD), which is easily preventable, is the main known etiology of night blindness. Malnutrition is a common health issue in Bashagard and some other areas in the Hormozgan province of Iran. The aim of the current study was to determine the prevalence of night blindness in Bashagard.
Methods: This descriptive cross-sectional study was done on 814 Bashagard residences. Data was analyzed using SPSS software and descriptive studies.
Results: About 60% of the study participants were uneducated people or people with low education. Thirty-two out of 814 people that were studied had problems with night vision. Therefore, the prevalence of night blindness in Bashagard was 3.93%.
Conclusion: Prevalence of night blindness in Bashagard is three times higher than its prevalence in all of Iran. Therefore, preventive interventions such as dietary regimes with vitamin A enrichments or supplementations are recommended.
Key words: night blindness, vitamin A deficiency, malnutrition

Ethics of Publishing Case Reports: Do We Need Ethics Approval and Patient Consent?
An editorial by Dr. Mehrdad Jalalian
The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.
To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
