PURPOSE: Atropine eye drops have been shown to slow the progression of myopia, but there has been limited research on the effectiveness of 0.05% atropine in treating myopia. This study aimed to investigate the safety and efficacy of 0.05% atropine eye drops in controlling myopia in children. METHODS: The study included 424 participants aged 6 to 12 years between January 1, 2015, and January 1, 2021. Of these, 213 were randomly assigned to the 0.05% atropine group and 211 to the placebo group...

PURPOSE: Although eye abnormalities are reported in fetal alcohol spectrum disorders (FASD), no systematic review based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines has been undertaken. Our aim was to document the range and prevalence of eye abnormalities reported in children with prenatal alcohol exposure (PAE) and/or FASD. METHODS: Searches of electronic databases and manual searches. Eligible articles were observational studies in children with PAE and/or FASD; peer reviewed journal articles in the English language; and studies reporting quantitative or frequency data on functional/structural eye abnormalities...

PURPOSE: Animal studies have suggested that Erythropoiesis-Stimulating Agents (ESAs) may increase vascular endothelial growth factor (VEGF)-related retinopathies, but this effect is unclear in humans. This study evaluates the risk of vision-threatening diabetic retinopathy (VTDR), defined as either diabetic macular edema (DME) or proliferative diabetic retinopathy (PDR), in patients exposed to an ESA. METHODS: Two analyses were performed. First, a retrospective matched-cohort study was designed using a de-identified commercial and Medicare Advantage medical claims database...

PURPOSE: To assess the relationship between serum vitamin D levels and myopia in people aged 12-50 years using the National Health and Nutrition Examination Survey (NHANES) database. METHODS: Demographics, vision, and serum vitamin D levels from NHANES (2001-2006) were analyzed. Multivariate analyses were performed to examine the relationship between serum vitamin D levels and myopia while controlling for sex, age, ethnicity, education level, serum vitamin A, and poverty status...

PURPOSE: To determine the burden of trachoma and its related risk factors among the underserved population of sixteen states/union territories (UTs) in India. METHODS: Trachoma rapid assessment (TRA) was conducted in seventeen Enumeration Units (EUs) spanning sixteen states/UTs in India according to standard WHO guidelines. A total of ten clusters were selected in each EU and 50 children aged 1-9 years were assessed clinically for signs of active trachoma and facial cleanliness in each cluster...

INTRODUCTION: Trichiasis is present when in-turned eyelashes touch the eyeball. It may result in permanent vision loss. Trachomatous trichiasis (TT) is caused by multiple rounds of inflammation associated with conjunctival Chlamydia trachomatis infection. Surveys have been designed to estimate the prevalence of TT in evaluation units (EUs) of trachoma-endemic countries in order to help develop appropriate programme-level plans. In this study, TT-only surveys were conducted in five EUs of The Gambia to determine whether further intensive programmatic action was required...

PURPOSE: Trachoma is an eye disease caused by the bacterium Chlamydia trachomatis (Ct). It can lead to permanent vision loss. Since 2007, Burundi has included trachoma elimination as part of its fight against neglected tropical diseases and blindness. This study presents the results of trachoma baseline, impact and surveillance surveys conducted in Burundi between 2018 and 2021. METHODS: Areas were grouped into evaluation units (EU) with resident populations of between 100,000 and 250,000 people...

PURPOSE: The urbanization of suburbs has a significant impact on ocular health, however, the effect of this phenomenon on the epidemiology of eye diseases in the sub-urbanization region of China remains unclear. In this context, the population-based Beichen Eye Study (BCES) was conducted in the Beichen District of Tianjin, China. This article aims to summarize the background, design scheme and operation process of the study. The Chinese Clinical Trial Registry number was ChiCTR2000032280...

PURPOSE: Trachoma is a public health problem in 42 countries. Inflammation associated with repeated ocular infection with Chlamydia trachomatis can cause the eyelid to scar and turn inwards, resulting in the eyelashes rubbing against the eyeball, known as trachomatous trichiasis (TT). In Guinea, baseline surveys conducted in 2013 reported inflammatory trachoma prevalences below the World Health Organization (WHO) threshold for elimination, but TT prevalences above threshold. Given this epidemiological context and time since baseline survey, TT-only surveys were conducted in selected districts to determine current TT prevalence...

PURPOSE: Several small studies have associated exposure to elevated average temperature with specific vision problems. However, no large-scale studies have examined the relationship between vision impairment and average area temperature in the general population. We conducted a cross-sectional analysis of a large nationally representative sample of older adults to further explore this relationship. METHODS: Secondary analysis of the American Community Survey (ACS)...

PURPOSE: To examine the association between area-level socioeconomic deprivation and orbital trauma among emergency ophthalmology consults. METHODS: We conducted a cross-sectional study using 5-year Epic data for all hospital-based ophthalmology consults at the University of Maryland Medical System, and the Distressed Communities Index (DCI) data for area-level socioeconomic deprivation. We ran multivariable logistic regression models adjusting for age to compute odds ratios (OR) and 95% confidence intervals (CI) for the association between the DCI quintile 5 distressed score and orbital trauma...

PURPOSE: The utility of screening for early diagnosis of glaucoma remains a widely debated topic in the care of ophthalmic patients. There are currently no population-based guidelines regarding screening for glaucoma. The purpose of this study is to determine the utility of optical coherence tomography (OCT) for early glaucoma screening in a population of diabetic patients. The results of this study may inform future screening practices. METHODS: The current study is a post hoc analysis of OCT data collected from diabetic patients screened for eye disease over 6 months...
