RESUMO
PURPOSE: To report a case of uveal effusion syndrome in association with primary COVID-19 infection to share our experience and insight in diagnosing and managing this unique case. CASE PRESENTATION: A 56-year-old woman presented with angle closure glaucoma of both eyes. Further examination and imaging revealed the etiology to be related to bilateral uveal effusions and choroidal thickening in the setting of recent COVID-19 infection. The patient's glaucoma was managed with bilateral iridotomies and medical therapy, while the precipitating uveal effusions resolved with treatment on oral steroids. CONCLUSION: While uveal effusion syndrome has been associated with COVID-19 vaccination, it has not yet been reported after primary infection. Recognition of this rare phenomenon will allow for better diagnosis and treatment in future cases.
RESUMO
PURPOSE: To investigate and compare the association of corneal hysteresis (CH) in patients with secondary glaucoma to control patients and patients with primary open-angle glaucoma (POAG). Additionally, to determine the consistency of CH measurements in patients with secondary glaucoma. METHODS: A total of 84 patients (121 eyes) were prospectively included in this study. Twenty-three patients (46 eyes) were healthy controls, 24 patients (40 eyes) were diagnosed with POAG, and 27 patients (35 eyes) were diagnosed with a form of secondary glaucoma. CH and intraocular pressure (IOP) were measured using the Ocular Response Analyzer. Three measurements per eye were performed and used for the analysis and to determine fluctuations in CH data. One-way ANOVA with post-hoc Bonferroni analysis and Chi-Squared testing was done to determine differences between groups. RESULTS: All patients were matched for age. Patients in both POAG and secondary glaucoma groups were matched for age and IOP. All groups had similar sex and racial compositions as well as similar proportions of diabetes, hypertension, and hyperlipidemia. CH was lower (p < .05) in patients with POAG (9.32 ± 1.64) and secondary glaucoma (7.89 ± 3.18) when compared to healthy controls (11.16 ± 1.60). Fluctuations in CH measurements were minimal in all groups. Further analysis of the secondary glaucoma group revealed no differences in CH between different types of secondary glaucoma (p > .05). CONCLUSION: Patients with secondary glaucoma have lower CH when compared to POAG or control groups. The ORA exhibits precision of CH measurements for control, POAG, and secondary glaucoma groups, making it a reliable tool in management of secondary forms of glaucoma.

PRCIS: Both micropulse (MP-CPC) and continuous wave (CW-CPC) cyclophotocoagulation exhibited short-term effectiveness in lowering IOP, followed by reversion to near baseline levels 12 months after laser treatment. OBJECTIVE: To determine and compare the effectiveness and safety of MP-CPC and CW-CPC in patients diagnosed with pediatric glaucoma. METHODS: A retrospective cohort study was conducted on a total of 28 patients (81 eyes) diagnosed with pediatric glaucoma either undergoing MP-CPC or CW-CPC. Intraocular pressure (IOP) measurements, number of glaucoma medications, and the onset of complications were collected at baseline, 1-month, 3-month, 6-month, and 12-month intervals. Success rate (SR) was defined as eyes achieving IOP ≤21 mm Hg and ≥5 mm Hg and a 20% reduction in IOP at the last follow-up visit. RESULTS: All patients either undergoing MP-CPC or CW-CPC were matched for age (mean ± SD; 1.76 ± 1.69 vs 1.56 ± 2.49 y). Patients undergoing MP-CPC had significant decreases in IOP from baseline IOP at 1, 3, and 6 months with a 22% SR at 12 months. CW-CPC had a significant decrease in IOP from baseline IOP at all follow-ups, with a 27% SR at 12 months. At the 12-month follow-up, the CW-CPC cohort exhibited a significantly larger overall drop in IOP when compared with the MP-CPC cohort, (7.99 ± 7.95 vs 1.78 ± 6.89, P < 0.05); however, the difference in SR between treatment groups (27% vs 22%) at 12 months was not significant ( P > 0.05). Complications were minimal for both groups. CONCLUSION: Both MP-CPC and CW-CPC exhibited short-term effectiveness in lowering IOP, followed by reversion to near baseline levels 12 months after laser treatment. Both MP-CPC and CW-CPC exhibited similar SR at 12 months, 22% and 27% respectively.

Background: Mallampati scoring is a common exam method for evaluating the oropharynx as a part of the airway assessment and for anticipation of difficult intubation. It partitions the oropharynx into 4 categories with scores of 1, 2, 3, and 4. Even though its reliability is known to be limited by confounding factors such as patient positioning, patient phonation, tongue protrusion, and examiner variability, the effect of respiration, i.e., inspiration and expiration, has not yet been formally studied. Methods: Mallampati scores were collected from 100 surgical patients during both inspiration and expiration and later compared to the score obtained in the medical record, determined by a board certified anesthesiologist. Results: Score deviations from the medical record reference were compared for both inspiration and expiration showing that respiration affects Mallampati scores; for some patients, the scores improved (i.e., decreased), while in others they worsened (i.e., increased). The respiratory change effect was quantified and visualized by plotting the area under the curve of the histogram of the deviations. 42% of the patients had a worsening of scores by 1 or 2 points with inspiration while 36% of the patients had a worsening of scores by 1 or 2 points with expiration. Conclusions: Mallampati scoring is commonly used in evaluating the oropharynx as a part of the airway assessment and as a screening tool for difficult intubations. However, as this study points out, the respiratory cycle substantially affects the Mallampati scoring system, with significant deviations of 1 or 2 points. In a scoring system of 4 score categories, these deviations are remarkable.
RESUMO
Approximately 21,000 consumer product-related ocular injuries occurred in infants in the United States from 2009 to 2019; toys being the most common (12.9%) consumer product in the 1- to 4-month age cohort, detergents in the 5- to 8-month (21.6%) cohort, and chemicals for the 9- to 12-month (34.0%) age cohort. These results identify an important preventable consumer product-related public health problem in infants. [J Pediatr Ophthalmol Strabismus. 2023;60(4):e41-e44.].

OBJECTIVE: To determine the effectiveness of netarsudil, 0.02% in lowering intraocular pressure (IOP) in patients with secondary forms of glaucoma. METHODS: A total of 77 patients (98 eyes) with either primary open-angle glaucoma (POAG) or secondary glaucoma were reviewed retrospectively over the course of 1 year after starting netarsudil. The secondary glaucoma group was comprised of patients with uveitic, pseudoexfoliative, neovascular, congenital, and other forms of secondary glaucoma. Patient IOP measurements were collected at baseline and at 1-, 3-, 6-, and 12-month intervals. Two sample t tests and 1-way analysis of variance were used to determine differences in IOP reductions following netarsudil treatment. RESULTS: Patients with POAG or secondary glaucomas were matched for age (mean ± SD: 69.1 ± 16.0 years vs. 64.5 ± 21.2 years; pâ¯=â¯0.30). Both the POAG and secondary glaucoma patients exhibited significant decreases in IOP at each time point (1, 3, 6, and 12 months) when compared with baseline (p < 0.05). Both groups showed similar overall decreases in IOP from baseline after 1 year of treatment (6.0 ± 4.5 mm Hg vs. 6.6 ± 8.4 mm Hg; pâ¯=â¯0.70). Forty-sex percent of POAG patients achieved an IOP of <14 mm Hg compared with 17% of secondary glaucoma patients. Among the secondary glaucoma subtypes, netarsudil was found to be most effective for treating uveitic glaucoma, showing a decrease in IOP of 9.5 mm Hg after 12 months (pâ¯=â¯0.02). CONCLUSION: Netarsudil is effective in lowering IOP in patients with certain forms of secondary glaucoma and should be considered for IOP management in those with uveitic glaucoma.
RESUMO
PURPOSE: In July 2022, the World Health Organization (WHO) declared monkeypox virus's global spread a "public health emergency of international concern." About a quarter of monkeypox cases feature ophthalmic symptoms. We assessed trends in worldwide search interest in monkeypox ophthalmic involvement and inclusion in online search engine queries. METHODS: The following keywords were searched on Google Trends from April 1, 2022, to August 12, 2022: monkeypox + eye, pink eye, eye infection, eyelid, vision, blurry vision, vision loss, blindness, eye symptoms, eye problems, eye pain, eye redness, conjunctivitis, conjunctiva, cornea, keratitis, corneal ulcer, and blepharitis. We analyzed trends, correlated search interest with case count data, and compared popularity of search terms via nonparametric Mann-Whitney-U analysis. Inclusion of ophthalmic symptoms in Google search results for "monkeypox symptoms" was assessed. RESULTS: "Monkeypox eye" had the highest average search interest worldwide and in the United States. Search interest peaked between mid-May and late July 2022. When compared to interest in "monkeypox rash," the most searched monkeypox symptom, the average interest in "monkeypox eye" was lower (p < 0.01). Of the first 50 results from the Google search of "monkeypox symptoms," 10/50 (20%) mentioned ophthalmic symptoms. 6/50 (12%) mentioned the eye as a route of virus transmission. CONCLUSION: Search interest in monkeypox ophthalmic symptoms corresponds with geographic and temporal trends, i.e., timing and location of the first reported non-endemic cases and WHO announcement. Although ophthalmic symptoms are not as widely searched currently, inclusion in public health messaging is key for diagnosis, appropriate management, and reduction of further transmission.

Enhanced exercise capacity is not only a feature of healthful aging, but also a therapy for aging patients and patients with cardiovascular disease. Disruption of the Regulator of G Protein Signaling 14 (RGS14) in mice extends healthful lifespan, mediated by increased brown adipose tissue (BAT). Accordingly, we determined whether RGS14 knockout (KO) mice exhibit enhanced exercise capacity and the role of BAT in mediating exercise capacity. Exercise was performed on a treadmill and exercise capacity was assessed by maximal running distance and work to exhaustion. Exercise capacity was measured in RGS14 KO mice and their wild types (WT), and also in WT mice with BAT transplantation from RGS14 KO mice or from other WT mice. RGS14 KO mice demonstrated 160 ± 9% increased maximal running distance and 154 ± 6% increased work to exhaustion, compared to WT mice. RGS14 KO BAT transplantation to WT mice, resulted in a reversal of phenotype, with the WT mice receiving the BAT transplant from RGS14 KO mice demonstrating 151 ± 5% increased maximal running distance and 158 ± 7% increased work to exhaustion, at three days after BAT transplantation, compared to RGS14 KO donors. BAT transplantation from WT to WT mice also resulted in increased exercise performance, but not at 3 days, but only at 8 weeks after transplantation. The BAT induced enhanced exercise capacity was mediated by (1) mitochondrial biogenesis and SIRT3; (2) antioxidant defense and the MEK/ERK pathway, and increased hindlimb perfusion. Thus, BAT mediates enhanced exercise capacity, a mechanism more powerful with RGS14 disruption.

The use of marijuana for the treatment of glaucoma has been widely debated amongst ophthalmologists and glaucoma specialists. Recent evidence suggests the majority of ophthalmologists do not support the use of marijuana as active treatment for glaucoma. However, there has been no investigation into understanding the public's direct perception of the efficacy of marijuana in glaucoma treatment. By using Twitter as a tool to understand the public's thoughts, tweets were analyzed over the last 2 years. Of the 700 tweets analyzed, 72% (n=503) of tweets were in favor of cannabis use in the treatment of glaucoma, whereas 18% (n=124) were evidently opposed. The majority of those in favor came from accounts of individual users (n=391; 56%) whereas those that opposed marijuana as a treatment came from accounts of health care media, ophthalmologists, and other health care workers. The discrepancy between the public and ophthalmologists and other health care professionals requires recognition and further action to better educate the public on the role of marijuana in glaucoma treatment.

PURPOSE: We investigated the effects of gut microbes, and the mechanisms mediating the enhanced exercise performance induced by exercise training, i.e., skeletal muscle blood flow, and mitochondrial biogenesis and oxidative function in male mice. METHODS: All mice received a graded exercise test before (PRE) and after exercise training via forced treadmill running at 60% to 70% of maximal running capacity 5 d·wk -1 for 5 wk (POST). To examine the role of the gut microbes, the graded exercise was repeated after 7 d of access to antibiotic (ABX)-treated water, used to eliminate gut microbes. Peripheral blood flow, mitochondrial oxidative capacity, and markers of mitochondrial biogenesis were collected at each time point. RESULTS: Exercise training led to increases of 60% ± 13% in maximal running distance and 63% ± 11% work to exhaustion ( P < 0.001). These increases were abolished after ABX ( P < 0.001). Exercise training increased hindlimb blood flow and markers of mitochondrial biogenesis and oxidative function, including AMP-activated protein kinase, sirtuin-1, PGC-1α citrate synthase, complex IV, and nitric oxide, all of which were also abolished by ABX treatment. CONCLUSIONS: Our results support the concept that gut microbiota mediate enhanced exercise capacity after exercise training and the mechanisms responsible, i.e., hindlimb blood flow, mitochondrial biogenesis, and metabolic profile. Finally, results of this study emphasize the need to fully examine the impact of prescribing ABX to athletes during their training regimens and how this may affect their performance.

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.

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.

RESUMO
PURPOSE: To characterize trends in ocular tennis injuries over the last 20 years. METHODS: The National Electronic Injury Surveillance System was utilized to characterize tennis-related eye injuries in a nationally representative sample of emergency department visits. Data were divided into 5 age groups, and various demographic information was obtained. RESULTS: Approximately 16,000 tennis-related ocular injuries were identified with males being affected nearly 2:1 compared to females. The youngest age group (0-20) had the greatest proportion of injuries, with most injuries in boys 11-15 years old. Injuries occurred most often during the spring season. Most patients were treated and released from the ED. Of those patients who were hospitalized, one-third had an open globe injury. CONCLUSIONS: The overall number of injuries trended downward during the timespan of the study. Although most patients did not experience serious visual consequences, the greatest proportion of ocular tennis injuries occurred in the pediatric age group in whom the risk of amblyopia is high. Primary care providers and tennis regulatory bodies should consider recommending eye safety sports goggles in children to mitigate the potential for significant visual morbidity.
