Population perceived eye strain due to digital devices usage during COVID-19 pandemic.

PURPOSE: To assess the magnitude severity and determinants of eyestrain and the use of digital devices in a Saudi population during the COVID-19 pandemic lockdown. METHODS: This web-based survey was conducted in September 2020 and enrolled only Saudi nationals 15 years or older. Data were collected on demographics, eye strain related symptoms, severity, and the use of optical aids during the COVID-19 lockdown. The frequency and severity of eye strain were calculated. A Computer Vision Syndrome (CVS) score was graded as none/mild moderate and severe, based on the sum of 15-eye strain related signs and symptoms. Correlation analysis was performed for determinants of CVS. RESULTS: The study sample was comprised of 2009 individuals with median age of 20 years. Among those who used digital devices for more than 6 h daily, the main reasons for use were work and social purposes among 68.4%, and 61% of respondents, respectively. The prevalence of knowledge on CVS and the '20-20 rule for using digital devices' was 9.4% and 6.9, respectively. The most common symptoms of eye strain from digital device usage were headache, burning, itching, tearing, and redness of eyes. Six hours of daily usage of digital devices was positively associated to the grade of eye strain severity during the COVID-19 lockdown (P < 0.05)). CONCLUSION: The Saudi population experienced eye strain during COVID-19 lockdown due to excessive digital devices usage. Longer duration of digital device usage was associated to eye strain. Health care providers should educate the general population on measures to mitigate eye strain due to digital devices. Trial registration ID None applicable.

Bilateral Papilledema and Right Esotropia as an Initial Presentation of Acute Myeloid Leukemia in a Young Girl.

Leukemia is a malignant hematologic neoplastic disease in which acquired mutations and genetic abnormalities in early hematopoietic precursors cause rapid proliferation of white blood cells (WBC). Acute myeloid leukemia (AML), a subtype of leukemia, is a rare form of cancer that typically manifests in adulthood. Symptoms typically arise due to abnormal proliferation of WBC. Ocular manifestations of such malignancies are rare and they occur more commonly in acute lymphoblastic leukemia (ALL) rather than AML. Furthermore, ophthalmic involvement usually is either a sign of central nervous system involvement or disease relapse. In this article, we report the case of a 14-year-old girl who presented initially with double vision and right eye squint. The patient was later diagnosed with AML with leptomeningeal involvement.
