ABSTRACT
PURPOSE: To evaluate the quality and reliability of medical information, the technical quality of the presentation of information, and the readability of informational websites that publish content on the definition, causes, symptoms, and treatment of glaucoma. DESIGN: A cross-sectional study was conducted to assess information published on websites with regard to glaucoma. SUBJECTS: The top 150 websites populated on a Google search using the keywords glaucoma, high intraocular pressure, and high eye pressure were chosen for evaluation. METHODS: Two independent reviewers assessed quality and reliability of each website using the DISCERN, Health on the Net Code (HONcode), and Journal of the American Medical Association (JAMA) criteria. The reviewers also evaluated technical quality by determining each website's ability to satisfy 10 unique features. Readability was assessed using the Readability Studio software (Oleander Software). MAIN OUTCOME MEASURES: Quality of information was analyzed using the DISCERN, HONcode, and JAMA criteria. To assess readability, the Bormuth Cloze Mean, Bormuth Grade Placement, Flesch Kincaid Reading Ease, Coleman-Liau Index, Gunning Fog Score, Simple Measure of Gobbledygook Index, Readability Score, Fry Estimate, Raygor Estimate, and the Overall Mean Readability metrics were used. A separate subanalysis categorized websites into institutional and private categories. RESULTS: Readability was poor among all websites, with most websites requiring a reading level higher than the 11th grade. The overall mean DISCERN score ± standard deviation (SD) was 3.0 ± 0.4, the mean HONcode score ± SD was 9.6 ± 1.8, and the mean JAMA score ± SD was 2.1 ± 1.1. The reviewers had moderate to excellent interrater reliability. Institutional websites (n = 39) had a higher mean DISCERN score (3.18 ± 0.33 vs. 2.95 ± 0.39, P < 0.05) and mean HONcode score (10.18 ± 1.90 vs. 9.34 ± 1.71, P < 0.05) than those of private websites (n = 111). Technical quality was higher among institutional websites (P < 0.05). CONCLUSIONS: An overwhelming majority of websites presented information of low quality, reliability, and readability. Institutional websites generally received higher scores than those received by private websites; however, overall scores were still substandard, which necessitates improvement of online information on glaucoma.
ABSTRACT
PURPOSE: To determine and analyze the 100 most cited articles in pediatric ophthalmology. METHODS: A literature search was conducted using the ISI Web of Science database on the top 100 most cited articles in pediatric ophthalmology. RESULTS: The 100 most cited articles were published between 1941 and 2018, with the greatest number published in both 2005 and 2012. A total of 29,731 citations were generated during the study period. There has been a significant increase in citations annually since 1941, with a peak number of citations in 2021 with 2,629 citations. Myopia, retinopathy of prematurity, and other forms of refractive error were the topics most studied and cited in these articles. Most of the articles were classified as either large cohort prospective/retrospective studies (34) or randomized clinical trials (19), with case reports/series being the least frequent (7). Investigative Ophthalmology & Visual Science (23), JAMA Ophthalmology (22), and Ophthalmology (22) published the majority of the articles. Institutions that conducted the majority of the studies presented include the National Eye Institute (10), the Ohio State University College of Optometry (9), and the Oregon Health & Science University (6). CONCLUSIONS: This bibliometric analysis provides a unique historical perspective of the literature in the field of pediatric ophthalmology that has not been studied before. The research in the field of pediatric ophthalmology is advancing quickly, with most articles and citations occurring within the past 15 years. The strong focus on prospective cohort studies and clinical trials reveals the importance of advancing the treatment of critical disease within the field of pediatric ophthalmology.

ABSTRACT
Prone positioning recently gain- ed more popularity from its use in COVID-19 management. It is gene--rally considered to improve respiratory mechanics via increased lung compliance. In surgery, prone positioning is typically encountered when it is a necessity to access certain posterior anatomic structures. Though certain post-operative complications from prone positioning are well known (e.g., postoperative vision loss), the potential intraoperative complications that it can have for respiratory com-pliance and O2 saturation, in the setting of general anaesthesia, are perhaps less familiar, as only a few studies showed improved respiratory mechanics in the setting of ge-neral anaesthesia [1-3] and one study showed that prone positioning led to a 30-35% drop in respiratory compliance under general anaesthesia [4]. As the following case illustrates, proning is a critical point in the intraoperative course as it can sometimes lead to negative respiratory sequelae disrupting homeostasis.
