RESUMEN
PURPOSE OF REVIEW: We describe the history, utilization, and series results of panretinal photocoagulation (PRP) and ranibizumab and provide an analysis of PRP and ranibizumab usage before versus after the publication of the 2-year and 5-year results of the Diabetic Retinopathy Clinical Research Network (DRCR.net) Protocol S trial. RECENT FINDINGS: Number of ranibizumabs performed began to increase and number of PRPs performed began to decrease in 2016. After publication of the 2-year results, there was significant negative trend in PRP services and significant positive trend in ranibizumab services (both Pâ<â0.001). After publication of the 5-year results, there was significant negative trend in PRP services (Pâ=â0.003). There were significant negative trends (all Pâ<â0.001) in reimbursement factors for PRP from 2013 to 2020: average work RVU (wRVU), nonfacility physical expense RVU, facility PE RVU, malpractice RVU (MP RVU). SUMMARY: Both PRP and ranibizumab have undergone numerous trials comparing their efficacy to other treatment options or no treatment at all. The publication of the 2-year results of Protocol S was associated with an increase in utilization of ranibizumab and decrease in utilization of PRP, with continued decrease after the publication of the 5-year results.

PURPOSE OF REVIEW: We describe the history and series results of pneumatic retinopexy (PnR)and provide an analysis of PnR utilization after publication of results of pneumatic retinopexy versus vitrectomy for the management of primary rhegmatogenous retinal detachment outcomes randomized trial (PIVOT). RECENT FINDINGS: No significant trends were found for average number of services ( P â=â0.153) of PnR after the publication of PIVOT results. SUMMARY: PnR is a rhegmatogenous retinal detachment (RRD) repair technique that was first described in the early 1900âs and has evolved over time to become a modern-day, minimally invasive, underutilized treatment option. Other repair techniques for RRD include scleral buckling and pars plana vitrectomy (PPV), which has been compared to the use of PnR in PIVOT. Results of PIVOT concluded that PnR offered superior visual acuity and noninferiority. PnR is underutilized in the United States even after publication of results of PIVOT deemed it a noninferior treatment. Lack of a significant increase in national utilization of PnR could be associated with multifactorial clinician, systems, and financial reasons in the real-world setting.

PURPOSE: To identify trends in female pediatric ophthalmologist authorship and representation at the American Academy of Ophthalmology (AAO) Annual Meeting from 2018 to 2022. METHODS: Participant data from 2018 to 2022 were collected from the AAO website, organized by conference activity (papers, posters, instruction courses, videos, symposia, subspecialty day, and awards), and analyzed by sex using an online tool. Chi-squared and odds ratio analyses were performed to determine trends in authorship sex and associations between the sex of paper and poster authors in each category. RESULTS: Of 923 pediatric ophthalmology presentations from 2018 to 2022, 46.2% (426 of 923) of presenters and 46.6% (281 of 603) of unique individual participants were women. Overall, 48% (174 of 362) of first and senior authors of papers and posters were women. No significant difference or association between female first and senior authors was observed (52% vs 44%, P = .14; odds ratio 1.59, P = .13). There was no significant change in the proportion of total female presenters from 2018 to 2019 (-3.09%, P = .53), 2019 to 2020 (0.76%, P = .88), 2020 to 2021 (9.09%, P = .09), 2021 to 2022 (-5.68%, P = .30), or 2018 to 2022 (1.08%, P = .84). CONCLUSIONS: Since 2018, female representation at the AAO Annual Meeting has remained consistent and nears 50%. The lack of a significant difference between the proportion of female first and senior authors suggests that junior female pediatric ophthalmologists are climbing the ranks and more broadly engaging in mentorship roles. Considering the increasing proportion of female pediatric ophthalmologists, the absence of corollary, statistically significant increases in female participation may be of concern.

Purpose Ophthalmic surgeons are at an increased risk for musculoskeletal disorders resulting from ophthalmology-specific routines and equipment, which have become widely associated with poor posture. The purpose of this study was to observe the effect that a commercially available posture trainer, Upright Go, can have on the improvement of posture of ophthalmic surgeons. Methods Eight ophthalmologists-in-training were studied over a period of 4 weeks during their surgical rotations between September 2020 and June 2021. Participants underwent an "observation" period, followed by a 2-week "training" period, then a final "testing" period. The percentage of time users spent upright intraoperatively pre- and posttraining was evaluated. Pre- and poststudy surveys were also administered to help measure participant satisfaction and self-reported changes in posture. Results All eight participants demonstrated an increase in the percentage of time spent upright after the training period. Across all participants, the total average percentage spent upright in the observation period was 59.8%, while in the testing period was 87.1%, resulting in an average improvement of 27.3% of time spent in an upright position after the completion of the training period ( p < 0.0001). The range of improvement of time spent upright was 16.0 to 46.5%. Conclusion This cohort study utilized the Upright Go device to help determine the effect that its training could have on the improvement of posture in ophthalmic surgeons. The results indicated a significant increase in the average proportion of time spent with upright posture compared after the training period.
RESUMEN
PURPOSE: To report the trends of immunosuppressive drug use for non-infectious uveitis and explore their relationship with industry payments. METHODS: A retrospective review of ophthalmologists reimbursed by Medicare for the administration of adalimumab (ADA), repository corticotropin (RCI), methotrexate (MTX), and mycophenolate mofetil (MMF) between 2014 and 2018. RESULTS: A total of 316 ophthalmologists were reimbursed by Medicare for 1567 ADA, 465 RCI, 1752 MTX, and 12 333 MMF administrations. The number and dollar amount of industry payments were positively associated with ADA and RCI use (P < 0.001). From 2014 to 2018, there was a positive trend in the proportion of ADA (P = 0.007) and RCI (P = 0.007) used and negative trend in the proportion of MMF (P = 0.025) used. CONCLUSION: From 2014 to 2018, the use of ADA and RCI increased while MMF decreased and MTX remained stable. There was a positive association between ADA and RCI use and physician-industry interactions. A causal relationship is not determined.
RESUMEN
Background The outcome of a statistical test is to accept or reject a null hypothesis. Reporting a metric as "trending toward significance" is a misinterpretation of the p-value. Studies highlighting the prevalence of statistical errors in the urologic literature remain scarce. We evaluated abstracts from 15 urology journals published within the years 2000-2021 and provided a quantitative measure of a common statistical mistake-misconstruing the function of null hypothesis testing by reporting "a trend toward significance." Materials and methods We performed an audit of 15 urology journals, looking at articles published from January 1, 2000, to January 1, 2022. A word recognition function in Microsoft Excel was utilized to identify the use of the word "trend" in the abstracts. Each use of the word "trend" was manually investigated by two authors to determine whether it was improperly used in describing non-statistically significant data as trending toward significance. Statistics and data analysis were performed using Python libraries: pandas, scipy.stats, and seaborn. Results This study included 101,134 abstracts from 15 urology journals. Within those abstracts, the word "trend" was used 2,509 times, 572 uses of which were describing non-statistically significant data as trending toward significance. There was a statistically significant difference in the rate of errors between the 15 journals (p < 0.01). The highest rate of improper use of the word "trend" was found in Bladder Cancer with a rate of 1.6% (p < 0.01) of articles. The lowest rate of improper use was found in European Urology, with a rate of 0.3% (p < 0.01). Our analysis found a moderate correlation between the number of articles published and the number of misuses of the word "trend" within each journal and across all journals every year (r = 0.61 and 0.70, respectively). Conclusion The overall rate of p-value misinterpretation never exceeded 2% of articles in each journal. There is significance in the difference in misinterpretation rates between the different journals. Authors' utilization of the word "trend" describing non-significant p-values as being near significant should be used with caution.
RESUMEN
BACKGROUND: The Altmetric Attention Score (AAS) aims to determine the impact of research articles throughout the internet and social media outlets. The AAS is a weighted average of the interaction on platforms including Twitter, Facebook, Reddit, and more. OBJECTIVES: The aim of this study was to investigate the relationship between the AAS and traditional bibliometrics across plastic surgery journals. METHODS: Articles, number of citations (NOC), and H-index information in Annals of Plastic Surgery (APS), Plastic and Reconstructive Surgery (PRS), Plastic and Reconstructive Surgery Global Open (PRS GO), and Aesthetic Surgery Journal (ASJ) from 2017, 2018, and 2019 were queried with the Scopus Online Tool. AAS metrics were collected with the Altmetric Score Calculator Bookmarklet. Descriptive statistics, Spearman rank-correlation analyses, and analyses of variance were performed to measure associations between NOC and AAS. RESULTS: A total of 3612 articles were analyzed. NOC was weakly correlated with AAS in APS, PRS GO, and ASJ, and moderately correlated with AAS in PRS. NOC was weakly correlated with Twitter mentions in APS, PRS GO, and ASJ, and moderately correlated in PRS. NOC was weakly correlated with news outlet reporting. The H-index of the first author showed more significant correlations with the AAS than the H-index of the last author. CONCLUSIONS: NOC and H-index of the first author correlated with AAS in the plastic surgery literature, suggesting AAS may be a useful adjunct to traditional bibliometrics when evaluating the impact and reach of peer-reviewed articles.
RESUMEN
PURPOSE OF REVIEW: Clinical trial publications may influence physician prescribing patterns. The Diabetic Retinopathy Clinical Research Network (DRCR.net) Protocol T study, published in 2015, examined outcomes of intravitreal antivascular endothelial growth factor (VEGF) medications for treatment of diabetic macular oedema (DME). This study investigates if the Protocol T 1-year results were associated with changes in prescribing patterns. RECENT FINDINGS: Anti-VEGF agents have revolutionized treatment of DME by blocking angiogenesis signalled by VEGF. Three commonly used anti-VEGF agents are on-label aflibercept (Eylea, Regeneron) and ranibizumab (Lucentis, Genentech) and off-label bevacizumab (Avastin, Genentech). SUMMARY: From 2013 to 2018, there was a significant positive trend in the average number of aflibercept injections for any indication ( P â<â0.002). There was no significant trend in the average number of bevacizumab ( P â=â0.09) and ranibizumab ( P â=â0.43) for any indication. The mean proportion of aflibercept injections per provider per year was 0.181, 0.217, 0.311, 0.403, 0.419 and 0.427; each year-by-year comparison was significant (all P â<â0.001), and the largest increase was in 2015, the year of publication of Protocol T 1-year results. These results imply and reinforce that clinical trial publications may have significant effects on ophthalmologist prescribing patterns.

Purpose: To describe the indications, outcomes, and complications associated with intraocular lens (IOL) exchange. Patients and Methods: To determine the relative frequency of postoperative complications between techniques for all patients undergoing IOL exchange from May 1, 2014 through August 31, 2020. Results: IOL exchange was performed in 511 eyes of 489 patients (59.7% men; mean age: 67.0 ± 13.9 years, median time from cataract procedure to IOL exchange: 47.5 months). Mean uncorrected visual acuity significantly improved from 20/192 Snellen equivalent (logMAR 0.981) preoperatively to 20/61 (logMAR 0.487) at last follow-up (P < 0.001). Overall, 384 eyes (78.7%) met their desired refractive outcome within ±1.0 diopter (D). The most frequent complication was cystoid macular edema (CME) (n=39, 7.6%). Iris-sutured technique was associated with significantly greater frequency of subsequent IOL dislocation (10.3%) than 4-point scleral sutured (0%, P = 0.002), anterior chamber IOL (ACIOL, 1.5%, P = 0.01), and 2-point scleral sutured (0%, P = 0.03) techniques. Yamane scleral-fixation technique was associated with significantly greater frequency of developing IOL tilt (11.8%) than ACIOL (0%, P = 0.002), 4-point scleral sutured (1.1%, P = 0.01), 2-point scleral sutured (0%, P = 0.04), and iris-sutured (0%, P = 0.04) techniques. Conclusion: IOL exchange significantly improved uncorrected visual acuity and more than three-quarters of eyes met the refractive goal. Certain techniques were associated with complications, including subsequent dislocation associated with iris-sutured technique and IOL tilt associated with Yamane scleral-fixation technique. This information may help guide surgeons in deciding between procedural techniques for individual patients during IOL exchange preoperative planning.
RESUMEN
Introduction: Like all United States physicians, ophthalmologists may be implicated in lawsuits claiming fraudulent medical practice. In order to educate, raise awareness, and mitigate fraudulent practice, we reviewed a legal database and analyzed fraud claims in ophthalmology lawsuits. Methods: A retrospective legal literature review was performed on jury verdicts and settlements from the online legal database LexisNexis Academic from 1985 through 2020 that were filed by or against an ophthalmologist, involved a fraud claim, and included a final decision or settlement. Cases were evaluated for factors including demographics of plaintiffs and defendants, type of fraud claim, ophthalmologist party status (plaintiff or defendant), decision outcome, and amount awarded (when applicable). Results: Of the 27 cases analyzed, all ophthalmologist defendants involved were male and the most common sub-specialty for an ophthalmologist defendant was refractive surgery. The most common fraud type was a fraud claim involving a malpractice lawsuit (12 of 27), followed by contract fraud and billing fraud. While the ophthalmologists in malpractice-related fraud cases experienced more rulings in favor of the defendant on the fraud claims (8 of 12), ophthalmologists in billing fraud cases experienced fewer rulings in their favor (0 of 5). Discussion: Ophthalmology lawsuits involving fraud claims occurred in various settings, including malpractice lawsuits, contract cases, and Medicare and Medicaid billing. Defendants were all male and most commonly refractive surgeons.
RESUMEN
Trainees may be implicated in malpractice lawsuits. Our study examines malpractice cases involving plastic surgery trainees. Methods: Using the LexisNexis database, verdicts and settlements from appellate state and federal cases between February 1988 and 2020 were queried. A nonrepresentative sample of 300 cases was compiled. Results: During a 32-year period, 21 lawsuits involving plastic surgery trainees were identified. Of these, 14 (66.67%) involved claims when a trainee was directly named as a defendant. Eighteen (85.7%) cases were due to procedural-related adverse outcomes, while three (14.3%) cases were associated with clinical or diagnostic-related adverse outcomes. Of the procedure-related cases, five (27.8%) occurred when the trainee was the lead surgeon. Allegations included lack of informed consent of procedure complications (11, 52.4%), procedural error (11, 52.4%), failure to supervise trainee (11, 52.4%), inexperience of trainee (eight, 38.1%), incorrect diagnosis or treatment (five, 23.8%), delay in evaluation (three, 14.3%), lack of awareness of resident involvement (three, 14.3%), lack of follow-up (three, 14.3%), and prolonged operative time (one, 4.8%). Median time from injury to lawsuit resolution was 3.8 years [interquartile range (IQR), 3-5 years]. Verdicts were ruled in favor of the defense in eight (38.1%) cases and for plaintiff in six (28.6%) cases. A settlement was made in seven (33.3%) cases. Median payout for plaintiff-won cases was $5,100,000 (IQR, $1,530,000-$17,500,000); the median settlement was $2,500,000 (IQR, $262,500-$4,410,000). Conclusions: Procedural error, improper informed consent, improper trainee supervision, and resident inexperience were the most common allegations. These factors can lead to financial and psychological burdens early in a physician's career.
RESUMEN
Importance: Ophthalmology-residency selection committees require robust metrics to review applicants. Participation in research activities is a core component of the application process for its perceived association with future academic productivity. Objective: To evaluate the correlation between the number of preresidency peer-reviewed publications (PPPs) and subsequent peer-reviewed publications or career choices of ophthalmology residency graduates. Design, Setting, and Participants: In this cross-sectional study, names of ophthalmology residency graduates were obtained. PubMed-indexed publication records were generated and publications were categorized as preresidency, intraresidency, and postresidency. First author and journal publications with an impact factor (IF) score of 3 or more were recorded. Current academic and community-based career statuses were designated. Names were obtained from cohort and alumni lists on residency program websites or by emailing program directors. Participants included US Accreditation Council for Graduate Medical Education-accredited ophthalmology residency graduates from 2013 to 2016. Main Outcomes and Measures: The primary outcome measure was association of PPPs with later publications, first authorship, and journal publications with an IF score of 3 or more. The secondary outcome measure was difference in characteristics associated with academic vs community-based ophthalmologist. Results: A total of 964 ophthalmologists (52% of graduates) were studied and most (85.5%) had PubMed-indexed publications. First authorship (ρ = 0.71; 95% CI, 0.67-0.74; P < .001) had a strong positive correlation with intraresidency publications, while journal publications with an IF score of 3 or more (ρ = 0.56; 95% CI, 0.51-0.60; P < .001) and PPPs (ρ = 0.38; 95% CI, 0.32-0.43; P < .001) had moderate and weak positive correlations, respectively. For postresidency publications, journal publications with an IF score of 3 or more (ρ = 0.86; 95% CI, 0.84-0.87; P < .001) had the strongest positive correlation followed by first authorship (ρ = 0.77; 95% CI, 0.74-0.79; P < .001) and PPPs (ρ = 0.26; 95% CI, 0.20-0.31; P < .001). Preresidency (t = 3.3; P = .001), intraresidency (t = 4.1; P < .001), postresidency (t = 7.5; P < .001), first author (t = 6.6; P < .001), and journal publications with an IF score of 3 or more (t = 5.9; P < .001) were greater for academic ophthalmologists compared with community-based ophthalmologists. Conclusions and Relevance: Preresidency publication history is at least weakly correlated with future publications or work in an academic setting among ophthalmologists. Multiple factors associated with academic productivity were evaluated; however, adjustment for multiple analyses was not done and further testing is required to prove whether these factors are predictive.

IMPORTANCE: Traumatic eye injury is one of the leading causes of visual impairment in the United States, but there is limited information available in the literature about ocular trauma related to sports. OBJECTIVE: To evaluate the primary ocular diagnosis, type of sport, seasonal prevalence, and injury severity following ocular sports-related trauma. DESIGN: Cross-sectional study. SETTING: United States (US) hospital emergency departments (ED). PARTICIPANTS: Patients with sports-related ocular injuries in the National Electronic Injury Surveillance System All Injury Program (NEISS-AIP) database from January 1, 2010 to December 31, 2019. MAIN OUTCOME AND MEASURE: To identify and compare the type of sport, primary diagnosis of ocular injury, and injury severity. RESULTS: For 4,671 sports-related ocular injuries identified, the mean age of injury was 19.4±15.2 years (median: 15.0 years, 79% male). The largest proportion of injuries occurred in the 12-17 years of age cohort (38.6%), occurring during summer months (P< .001). The most common sports associated with eye injury were basketball (37.8%), baseball (13.8%),, and football (12.3%). There were 3,214 injuries (68.8%) deemed 'minor' anterior segment injuries, 359 injuries (7.7%) deemed 'major' anterior segment injuries, 31 injuries (0.7%) deemed 'minor' posterior segment injuries, 77 injuries (1.7%) deemed 'major' posterior segment injuries, and 990 injuries (21.2%) of unknown severity. Basketball-related ocular trauma had a greater frequency of corneal/scleral abrasions than baseball (P < .001), soccer (P < .001), tennis (P = .03), softball (P = .001), and paintball (P = .02). Baseball-related ocular trauma had a greater frequency of contusions than basketball (P < .001), football (P < .001), soccer (P < .001), volleyball (P< .001). Paintball and soccer were more associated with 'major' anterior and posterior ocular injuries than basketball (P < .001, for both). CONCLUSION AND RELEVANCE: Sports-related trauma remains a highly prevalent cause of eye-related visits to the emergency room, particularly in young male adolescents in the spring and summertime. While most diagnoses were deemed 'minor' injuries with basketball associated with corneal/scleral abrasions and baseball with contusions, paintball, and soccer were more significantly associated with 'major' anterior and posterior ocular injuries.

Introduction In recent decades, ophthalmology exposure in medical school has been increasingly reduced. In turn, medical students have expressed concern over their ophthalmic skills. Research investigating the status of ophthalmology education in U.S. undergraduate medical curricula is limited to institutional data devoid of the student or resident perspective. This study seeks to gain a better understanding of current ophthalmology education for U.S. medical students from the trainee point of view. Methods A cross-sectional survey was distributed to current U.S. medical students interested in ophthalmology and U.S. ophthalmology residents. Demographic data, ophthalmology curriculum information, respondent learning preferences, and personal reflections were recorded. Thematic analysis and chi-square tests were utilized. Results In total, 387/4,482 (8.6%) surveys were completed by respondents from 75 U.S. medical institutions. Most respondents were exposed to formal ophthalmology curriculum (63%), research (89%), mentorship (84%), and clinical experiences (87%) during medical school, and medical school curriculum was ranked the third most helpful resource for students to learn about ophthalmology. Yet, 29% of residents ( n = 55) did not feel confident in their diagnostic ophthalmology skills based on their medical school exposure. Student and resident recommendations for improving ophthalmology education delivery commonly referenced nontraditional ophthalmology resources such as online videos ( n = 83) to supplement traditional learning materials such as lectures ( n = 56). Discussion These findings suggest that primary ophthalmology exposure in medical school has shifted toward extracurricular activities such as research and clinical observation. Considering the increasing time demands placed on the medical education system, utilizing nontraditional educational materials to supplement current undergraduate medical education in ophthalmology may provide educators with a resource to improve learner confidence and resident preparedness.
RESUMEN
Background Studies in several fields of medicine have found that women published less during the COVID-19 pandemic, potentially due to an increase in domestic responsibilities. This study examines whether a similar pattern exists for female authorship in ophthalmology. Purpose To compare the proportions of female authorship published in high-impact ophthalmology journals before and during the COVID-19 pandemic. Methods A cross-sectional study analyzing authorship gender of articles published during the COVID-19 pandemic (between July and September 2020) compared with matched articles published in the same journals before the COVID-19 pandemic (between July and September 2019). Gender of the first and last authors was analyzed using an online gender determination tool. Results A total of 577 articles and 1,113 authors were analyzed. There was no significant difference in the average number of publications by male and female authors before and during the COVID-19 pandemic. There was a significant increase in the percentage of female first authorship from the prepandemic period (32%) to during the COVID-19 pandemic (40%; p = 0.01), but no significant increase in the last authorship ( p > 0.05). When analyzing only research articles, a similar increase in female first authorship was noted when comparing the publications before (31%) and during the COVID-19 pandemic (43%; p = 0.02). No significant differences were noted when analyzing the editorials ( p > 0.05). Conclusion While disparities continue to exist between male and female authorship, an increase in female first authorship was noted during the COVID-19 pandemic for overall articles as well as research articles. Precis During the COVID-19 pandemic, female authorship as first and last authors of peer-reviewed articles in high-impact ophthalmology journals was below 50%. However, while the overall rates of female authorship were unchanged, female first authorship significantly increased during the pandemic. These results differ from studies published in other medical fields that demonstrated a decrease in female authorship during the COVID-19 pandemic.
RESUMEN
Patients are becoming increasingly reliant on online platforms for obtaining health information. Previous research has shown that the quality of information available on the internet regarding novel medical therapies is generally poor and frequently misleading. Shock wave therapy represents a novel restorative therapy for erectile dysfunction (ED) that has recently gained attention. We hypothesised that online sources regarding shock wave therapy for ED would be fraught with misleading claims and unreliable health information. Our objective was to evaluate the quality and readability of online medical information on shock wave therapy as a treatment for ED. Websites were generated using a Google search of 'shock wave therapy for erectile dysfunction' with location filters disabled. Readability was analysed using the Readable software (Readable.com, Horsham, United Kingdom). Quality was assessed independently by three reviewers using the DISCERN tool. Articles were subdivided into those from private clinic websites and those from universities or news media websites. Statistical analysis was conducted using the Student's t test. Nine articles that resulted from the Google search had mean readability scores as follows: Flesch-Kincaid grade level (10.8), Gunning-Fog Index (13.67), Coleman-Liau Index (12.74), Simple Measure of Gobbledygook (SMOG) Index (13.33), FORCAST Grade Level (11.33), and Automated Readability Index (11.08). The mean Flesch Reading Ease score was 46.4. The articles had a mean DISCERN score of 3.1, suggesting 'moderate quality' content. Articles from universities (n = 2) or news sources (n = 3) had significantly higher DISCERN scores than articles from private medical practices (n = 4). There was no difference in readability scores between the groups. Articles from private clinics are just as readable as those from universities or news media, but they are significantly more biased and misleading. The current online material relating to shock wave therapy for ED may not adequately inform patients in their medical decisions making, thereby necessitating closer collaboration between the sources disseminating information and urologists.

In this review, we aim to summarise key articles that explore relationships between the gut and ocular surface microbiomes (OSMs) and immune-mediated dry eye. The gut microbiome has been linked to the immune system by way of stimulating or mitigating a proinflammatory or anti-inflammatory lymphocyte response, which may play a role in the severity of autoimmune diseases. Although the 'normal' gut microbiome varies among individuals and demographics, certain autoimmune diseases have been associated with characteristic gut microbiome changes. Less information is available on relationships between the OSM and dry eye. However, microbiome manipulation in multiple compartments has emerged as a therapeutic strategy, via diet, prebiotics and probiotics and faecal microbial transplant, in individuals with various autoimmune diseases, including immune-mediated dry eye.

Importance: The study team investigated costs associated with the ranibizumab port delivery system (PDS) for neovascular age-related macular (nAMD), an alternative to conventional intravitreal anti-vascular endothelial growth factor (VEGF) injections. Objective: To investigate costs of intravitreal anti-VEGF injections vs ranibizumab PDS for patients with neovascular AMD (nAMD). Design, Setting, and Participants: This cost analysis used trial data and Medicare reimbursement rates and included patients with nAMD who were receiving ranibizumab, aflibercept, bevacizumab injections, or ranibizumab PDS. Main Outcomes and Measures: The number of intravitreal ranibizumab, aflibercept, and bevacizumab injections to break even with costs of ranibizumab PDS. Total direct medical costs over 1 year and 5 years for the ranibizumab PDS arm with refills at fixed 6-month intervals compared with monthly or bimonthly injections were calculated using Medicare rates. Scenario and sensitivity analyses accounted for uncertainty and variation. Results: The mean (SD) number of ranibizumab, aflibercept, and bevacizumab injections to break even with the cost of ranibizumab PDS with 1 refill was 10.8 (1.3), 9.3 (1.1), and 34.5 (4.2), respectively. Ranibizumab PDS with fixed 6-month refills over 1 year cost $21â¯016 ($2102). Comparatively, monthly intravitreal ranibizumab cost $1943 (95% CI, -$3047 to $6932; P = .34) more, aflibercept cost $5702 (95% CI, $253-$11â¯151; P = .04) more, and bevacizumab cost $16â¯732 (95% CI, -$20â¯170 to -$13â¯294, P < .001) less. For bimonthly injections, aflibercept cost $7658 (95% CI, -$11â¯649.52 to -$3665.61; P = .006) less. Over 5 years, monthly intravitreal ranibizumab projected to cost $25â¯581 (95% CI, $2275-$48â¯887; P = .04) more, aflibercept cost $44â¯374 (95% CI, $18â¯623-$70â¯125; P = .008) more, and bevacizumab cost $67â¯793 (95% CI, -$82â¯501 to -$53â¯085; P < .001) less than PDS with fixed refills (mean [SD] cost, $89 218 [$8921]). For bimonthly injections, aflibercept cost $22â¯422 (95% CI, -$40â¯287 to -$45,56; P = .03) less. In scenario analyses, ranibizumab PDS with refills as needed offered cost savings compared with real-world intravitreal ranibizumab or aflibercept use at 5 years but not at 1 year. Conclusions and Relevance: In this cost analysis, ranibizumab PDS with 1 refill cost more than intravitreal ranibizumab or aflibercept injections if less than or equal to approximately 11 or 10 injections, respectively, are required within the first year. Long term, if less than 4.4 and 3.8 injections are needed per refill, intravitreal ranibizumab and aflibercept is lower cost. Ranibizumab PDS costs more than intravitreal bevacizumab injections throughout scenarios.

OBJECTIVE: To investigate the mechanical properties of 23-, 25-, and 27-gauge vitrectomy vitrectors across 3 different vitrectomy systems to inform surgical techniques. DESIGN: An experimental study that did not involve any human subjects. METHODS: Nine vitrectors (3 each of 23-, 25-, and 27 gauge) from Alcon, Dutch Ophthalmic Research Center (DORC), and Bausch & Lomb (B/L) were measured. Measurements were performed using electroforce displacement at the tip and 15 mm from the tip. Five measurements were performed at each location, and fully elastic deformation was ensured. MAIN OUTCOME MEASURES: The main parameter being measured was the force in grams (gf) necessary to deflect the vitrectors vertically downward by 1 mm, either at the tip of the vitrector or 15 mm from the tip. RESULTS: A total of 90 measurements were performed. Across brands, B/L demonstrated the least stiffness at both the tip and at the 15-mm point for 23-gauge (8.0±0.3gf, 67.3±1.0gf), 25-gauge (6.8±0.3gf, 60.5±0.4gf), and 27-gauge (3.3±0.1gf, 33.9±0.5gf) vitrectors. Although there was only a small decrease in the stiffness in the 25-gauge vitrector compared with the 23-gauge vitrector at the 15-mm point, this difference was statistically significant for Alcon (P < 0.001), DORC (P < 0.001), and B/L (P < 0.001). CONCLUSIONS: Based on this study, 25-gauge vitrectors, although larger than the 27-gauge vitrectors and less stiff than the 23-gauge vitrectors, may offer favorable compromise between stiffness and gauge size. However, surgeon experience, preference, and the type of surgery being performed should be paramount when making the final vitrector selection. Knowledge of these mechanical properties may aid surgeons in choosing between gauge size and vitrectomy system to optimize their comfort and efficiency.

Importance: The Altmetric attention score (AAS) provides new information to gauge the impact of a research article not found through typical metrics, such as impact factor or citation counts. Objective: To explore the association between AAS and common impact markers among high-impact ophthalmology journals from 2018 to 2019. Design, Setting, and Participants: All articles published in the American Journal of Ophthalmology (AJO), JAMA Ophthalmology (JAMAO), and Ophthalmology (OPH) from January 1, 2018, to December 31, 2019, were collected for this cross-sectional study. Excluded articles were those missing Altmetric data at the time of data collection. The AAS and associated social media impact for each article were collected with the AAS calculator bookmarklet. Spearman rank correlation analyses and analysis of variance tests were conducted to assess differences in various metrics between AJO, JAMAO, and OPH. The study included articles published of all document types (article, conference paper, editorial, erratum, letter, note, retracted, review, and short survey) and access status (open access and not open access). Main Outcomes and Measures: The correlation between citation counts and Altmetric variables including AAS. Results: A total of 2467 articles were published in the study period. There were 351 articles excluded owing to missing Altmetric data. Of the 2116 articles included in the analysis, 1039 (49.1%) were published in 2018, and 1077 (50.9%) were published in 2019; the mean number of citations was 8.8 (95% CI, 7.9-9.6) for AJO, 6.2 (95% CI, 5.3-7.1) for JAMAO, and 15.1 (95% CI, 13.3-17.0) for OPH. The mean AAS was 4.5 (95% CI, 3.3-5.6) for AJO (723 publications), 27.4 (95% CI, 22.1-32.8) for JAMAO (758 publications), and 15.1 (95% CI, 10.9-19.3) for OPH (635 publications). Citation rate was moderately correlated with AAS across the 3 journals (AJO, ρ = 0.39; P < .001; JAMAO, ρ = 0.41; P < .001; OPH, ρ = 0.40; P < .001), as well as minimally or moderately correlated with engagement or mention by Facebook posts (AJO, ρ = 0.38; P < .001; JAMAO, ρ = 0.24; P < .001; OPH, ρ = 0.20; P < .001), news outlet reporting (AJO, ρ = 0.12; P < .001; JAMAO, ρ = 0.38; P < .001; OPH, ρ = 0.19; P < .001), and Twitter posts (AJO, ρ = 0.40; P < .001; JAMAO, ρ = 0.38; P < .001; OPH, ρ = 0.42; P < .001). Conclusions and Relevance: Results of this cross-sectional study suggest that citation rate has a moderate positive correlation with online and social media sharing of research in ophthalmology literature. Peer-reviewed journals may increase their reach and impact by sharing their literature through social media and online platforms.
