Ten-Year Outcome of Boston Type I Keratoprosthesis Surgery at a Tertiary Care Center.

PURPOSE: The aim of this study was to report long-term outcomes of patients who have undergone Boston type I keratoprosthesis (KPro) surgery. METHODS: This study was a retrospective review. Inclusion criteria were KPro surgery between 2006 and 2012 and at least 10 years of follow-up. Demographics, ocular history, surgery indication, clinical variables, and postsurgical outcomes were recorded. Descriptive statistical analysis was performed. RESULTS: We identified 75 patients with KPro implantation, and 17 patients with at least 10 years of follow-up (median = 11.1 years; range, 10.0-12.8 years) were included. Of 17 eyes, 11 (64.8%) had their original device in situ, 3 (17.6%) had their second device in situ, 1 (5.9%) had the device removed and replaced with a donor keratoplasty, and 2 (11.8%) were enucleated. At the last follow-up, 11 eyes (64.7%) were able to maintain improvement in vision, 5 (29.4%) had worsened vision, 1 (5.9%) had stable vision, and 9 (52.9%) had visual acuity

Perspectives of Resident and Attending Ophthalmologists on Common Ethical Dilemmas in Research.

Purpose To assess how resident and attending ophthalmologists perceive and evaluate ethically controversial scenarios regarding mentorship, authorship, and ethics compliance that may occur during research involving residents. Methods An online survey was developed and contained 14 controversial vignettes based on common research scenarios that can occur when conducting research with trainees. The scenarios were designed to capture issues regarding three themes: mentorship, authorship, and compliance with ethical guidelines. Resident and attending ophthalmologists at eight military and civilian academic residency programs in the United States were invited to participate. Respondents used a Likert scale to assess the ethicality of the situations in addition to self-reported demographic characteristics. Results The response rate was 35.6% (77/216), consisting of 37.7% ( n = 29) residents and 62.3% ( n = 48) attendings. More attending ophthalmologists responded than residents ( p = 0.004). Many respondents identified controversies around compliance (67.3%) and authorship (57.1%) as unethical, whereas situations regarding mentorship were largely viewed as neutral to ethical (68.0%). Responses to two scenarios, one regarding mentorship and one regarding authorship, significantly differed between residents and attendings ( p = 0.001 and p = 0.022, respectively). Conclusion Academic ophthalmologists' perceptions of the ethicality of common research scenarios varied. There is a need for more prescriptive guidelines for authorship and mentorship ethics at all training levels to ensure consistency, fairness, and integrity of research.

Rates of Internal Hiring of Ophthalmology Faculty from their Institution of Training at Top Academic Medical Centers: A Cross-Sectional Study.

Background Throughout graduate and postgraduate education, trainees need to gauge the impact of training location on future institutions of practice. Objective We assessed rates of internal hiring of ophthalmology faculty at academic institutions from their same institution of training. Methods This was a cross-sectional study. We included 1,246 clinical ophthalmology faculty at the 13 top-ranked institutions listed in the 2021 U.S. News and World Report. Primary, emeritus, adjunct, and affiliate faculty were included. Publicly available information was collected from institutional websites and other online sources. Statistical analyses were conducted using t -tests or Mann-Whitney tests, chi-squared or Fisher's exact tests, and multivariate logistic regression. The main outcome measured was internal hires, defined as faculty who had completed residency and/or fellowship training at their current institution. Results In total, 47.3% of faculty were internal hires who completed residency or fellowship at the same institution. Among externally trained faculty, 27.7% completed residency and 56.0% completed fellowship at another top 13 programs. Internal hires were more frequently fellowship-trained, had a greater number of publications, and practiced in smaller departments ( p < 0.001, p < 0.001, and p = 0.002, respectively). A greater proportion of internal hires held leadership positions ( p = 0.012). Faculty practicing in the Midwest or West and with more years since residency graduation were less likely (odds ratio [OR], 0.29, 95% confidence interval [CI], 0.18-0.48; OR, 0.49, 95% CI, 0.31-0.78; OR, 0.98, 95% CI, 0.97-0.99, respectively) to be internal hires. Faculty with non-R01 National Institutes of Health funding were more likely to be internal hires (OR, 1.82, 95% CI: 1.12-2.96). Conclusions Training institution is key to determining the institution of practice. These results may be beneficial for trainees to consider when selecting a training program.

Barriers in Ophthalmology Residency Applications for Students Identifying as Underrepresented in Medicine: A San Francisco Match Analysis.

OBJECTIVE: There is a significant lack of ophthalmologists who self-identify as underrepresented in medicine (URiM) in the physician workforce. Prior literature has revealed bias in traditional metrics for selection relied on by resident programs such as United States Medical Licensing Examination (USMLE) scores, letters of recommendation (LOR), and induction into medical honors societies such as Alpha Omega Alpha (AOA). The purpose of this study was to elucidate race-based differences in word usage within ophthalmology residency letters of recommendation that may disproportionately affect URiM applicants. DESIGN: This was a retrospective, cohort study. SETTING: This was a multicenter study across the Wilmer Eye Institute at Johns Hopkins, the University of California San Francisco, and the University of North Carolina at Chapel Hill. PARTICIPANTS: San Francisco (SF) Match applications submitted to three ophthalmology residency programs between 2018 and 2020 were reviewed. URiM status, USMLE Step 1 score, and AOA membership were recorded. Letters of recommendation were analyzed using text analysis software. T-tests and chi-squared or Fisher's exact tests were used to compare continuous and categorical variables, respectively. Frequency of word/summary term usage in letters of recommendation were the main outcome measures. RESULTS: Relative to non-URiM applicants, URiM applicants had lower USMLE Step 1 scores (mean difference=7.0; p<0.001). Non-URiM letters of recommendation were more likely to describe applicants as "dependable" (p=0.009) and highlight "research" (p=0.046). URiM letters were more likely to describe applicants as "warm" (p=0.02) and "caring" (p=0.02). CONCLUSIONS: This study identified potential barriers for URiM ophthalmology residency applicants which can help guide future interventions to increase workforce diversity.

Opportunity Cost to Attending Surgeons of Intraoperative Training for Residents in Cataract Surgery.

Purpose: To estimate the opportunity cost to attending surgeons of teaching residents cataract surgery in the operating room. Patients and methods: Operating room records at an academic teaching hospital from July 2016 to July 2020 were analyzed in this retrospective review of cases. Cases were identified using Current Procedural Terminology (CPT) codes 66982 and 66984 for cataract surgery. Outcomes measured include operative time and work relative value units (wRVUs). Cost analysis was performed using the generic 2021 Medicare Conversion Factor. Results: Of 8813 cases, 2906 (33.0%) included resident involvement. For CPT 66982 cases, median (interquartile range (IQR)) operative time was 47 (22) minutes with resident involvement and 28 (18) minutes without (p<0.001). For CPT 66984 cases, median (IQR) operative time was 34 (15) minutes with resident involvement and 20 (11) minutes without (p<0.001). Median wRVUs was 78.5 (20.9) with resident involvement and 61.0 (14.4) without (p<0.001) which converted to an opportunity cost (IQR) per case of $1393.72 ($1055.63). Among cases involving residents, median operative time was significantly higher during the first and second quarters (p<0.001) and for every quarter when compared to cases performed by attendings only (p<0.001). Conclusion: Teaching cataract surgery in the operating room is associated with a considerable opportunity cost for attending surgeons.

Fate of Research Articles Reported by Ophthalmology Residency Applicants: What Happens to "Submitted" and "In Preparation" Articles?

OBJECTIVE: As coronavirus disease 2019 affects clinical training opportunities and with the transition of U.S. Medical Licensing Examination Step 1 to pass-fail, research may become increasingly important for evaluating ophthalmology residency applicants. Though publication misrepresentation has been studied among ophthalmology residency applicants, eventual publication rates of incomplete articles remain unknown. We aimed to determine publication rates for manuscripts listed as "submitted" or "in preparation" on ophthalmology residency applications and identify factors associated with unpublished manuscripts. DESIGN: San Francisco Match applications to the Wilmer Eye Institute for the 2019 ophthalmology residency cycle were retrospectively reviewed. Each applicant's number of "published," "submitted," and "in preparation" manuscripts was recorded, then verified 1.5 years later through PubMed, Google Scholar, or journal websites. Unverifiable manuscripts were deemed "unpublished." SETTING: Single academic institution (Wilmer Eye Institute, Baltimore, MD, USA) PARTICIPANTS: All 458 medical students who applied to the Wilmer Eye Institute for the 2019 ophthalmology residency cycle through the San Francisco Match. RESULTS: A total of 458 applications were reviewed. Of 428 "submitted" publications, 126 (29.4%) remained unpublished after 1.5 years. Of 324 manuscripts "in preparation," 215 (66.4%) remained unpublished. In a multivariate model, AOA was associated with not having an unpublished manuscript compared to applicants without AOA (OR: 0.423, p = 0.0163). Gender, Step 1 score, additional degrees, and a research year had no association. CONCLUSIONS: Nearly two-thirds of manuscripts listed as "in preparation" remained unpublished. Specific guidance from research mentors may help applicants better represent their publications in residency applications.

Ghost and Honorary Authorship in Ophthalmology: A Cross-Sectional Survey.

PURPOSE: To evaluate the rates of ghost and honorary authorship in ophthalmology and to determine risk factors associated with ghost and honorary authorship. DESIGN: Cross-sectional survey. METHODS: Corresponding authors of articles published in Ophthalmology, JAMA Ophthalmology, and the American Journal of Ophthalmology from June 2019 to December 2020 were emailed an electronic survey. The rates of ghost and honorary authorship, demographic characteristics of the corresponding authors with and without ghost and honorary authorship, and risk factors for ghost and honorary authorship were evaluated. RESULTS: Corresponding authors (n = 830) were emailed a survey and 278 total responses (34.1%) were received; 227 responses (27.9%) were complete and included for analysis. Most respondents (n = 206, 90.7%) believed that the International Committee of Medical Journal Editors (ICMJE) guidelines for authorship adequately address criteria for authorship. Twenty-seven corresponding authors (11.9%) reported characteristics of their articles that indicated the presence of both ghost and honorary authorship (95% CI, 7.7%-16.1%). One hundred fifteen (50.7%) reported honorary authorship (44.2%-57.2%), and 37 (16.3%) indicated ghost authorship (11.5%-21.1%). Being a resident or fellow corresponding author increased the risk of honorary authorship (OR 11.75; 1.91-231.57; P = .03). There were no factors that predicted articles having ghost authors. CONCLUSIONS: While many authors believe the ICMJE guidelines for authorship comprehensively delineate fair authorship practices, listing authors on scientific publications honorarily and excluding authors who qualify for authorship are relatively common practices in ophthalmological research. Further investigation into the drivers of honorary and ghost authorship practices in ophthalmology, and the effectiveness of preventive measures are needed to ensure fair authorship attributions.

Exposure of Ophthalmology Residents to Cornea and Keratorefractive Surgeries in the United States.

Purpose To describe the cornea and keratorefractive surgeries experience of U.S. ophthalmology residents. Methods Deidentified case logs of residents graduating in 2018 were collected from ophthalmology residency program directors in the United States. Using Current Procedure Terminology codes, case logs were reviewed in the categories of cornea and keratorefractive surgeries. Accreditation Council for Graduate Medical Education national graduating resident surgical case logs on cornea procedures published from 2010 to 2020 were also analyzed. Results Case logs were received for 152/488 (31.1%) residents from 36/115 (31.3%) ophthalmology residency programs. The most common procedures logged by residents as primary surgeons were pterygium removal (4.3 ± 4.2) and keratorefractive surgeries (3.6 ± 6.2). Residents logged an average of 2.4 keratoplasties as primary surgeon, performing an average of 1.4 penetrating keratoplasties (PKs) and 0.8 endothelial keratoplasties (EKs). As assistants, the most common procedures logged were keratorefractive surgeries (6.1 ± 4.9), EKs (3.8 ± 3.3), and PKs (3.5 ± 2.3). Medium or large residency class size was associated with higher cornea procedural volumes (odds ratio: 8.9; 95% confidence interval: 1.1-75.6; p < 0.05). Conclusion The most common cornea surgeries performed by residents include keratoplasty, keratorefractive, and pterygium procedures. Larger program size was associated with greater relative cornea surgery volume. More specific guidelines for logging of procedures could provide a more accurate assessment of resident exposure to critical techniques such as suturing as well as reflect trends in current practice such as the overall increase in EKs.

Trends in Cornea Fellowship Applications and Applicant Characteristics: A San Francisco Match Analysis.

Purpose We investigate trends in cornea fellowship positions filled over time and applicant characteristics associated with matching into cornea fellowship. Methods Characteristics of cornea fellowship applicants were assessed using deidentified 2010 to 2017 San Francisco (SF) Match data. Publicly available SF Match cornea fellowship data including the number of participating programs, number of positions offered, number of positions filled, percentage of positions filled, and number of vacancies from 2014 to 2019 were also analyzed as data from 2010 to 2013 were unavailable. Results From 2014 to 2019, the number of cornea fellowship programs increased by 11.3% (mean 2.3% per year, p = 0.006) and the number of positions offered increased by 7.7% (mean 1.4% per year, p = 0.065). Of 1,390 applicants from 2010 to 2017, 589 (42.4%) matched into cornea. After controlling for potential covariates, graduation from a U.S residency program (odds ratio [OR]: 6.15, 95% confidence interval [CI]: 4.05-9.35, p < 0.001) and a greater number of interviews completed (OR: 1.35, 95% CI: 1.29-1.42, p < 0.001) were associated with increased odds of cornea fellowship match. A greater number of applied programs (OR: 0.97, 95% CI: 0.95-0.98, p < 0.001) was associated with decreased odds of matching into cornea fellowship. The proportion of applicants matching into cornea fellowship increased until 30 applications. Conclusions The number of cornea fellowship programs and positions increased from 2014 to 2019. Graduation from a U.S residency program and a greater number of interviews completed were associated with an increased likelihood of cornea fellowship match. Unlike applying to any ophthalmology subspecialty fellowship, applying to greater than 30 cornea fellowship programs was associated with decreased odds of matching.

Cataract Surgery Numbers in U.S. Ophthalmology Residency Programs: An ACGME Case Log Analysis.

PURPOSE: To describe and assess the cataract experience of ophthalmology residents throughout the United States (U.S.). METHODS: Cataract procedures logged by graduating ophthalmology residents nationwide and published by the Accreditation Council for Graduate Medical Education (ACGME) from 2009 to 2020 were analyzed using linear regression on log-transformed response variables with robust variance. RESULTS: As primary surgeon, average numbers logged for phacoemulsification increased yearly by an average of 4.1% prior to 2019 and then decreased by 22.1% in 2019 for an overall average yearly increase of 2.9% (95% CI: 0.5, 5.4%, p = .03), non-phacoemulsification extracapsular extraction decreased yearly by an average of 4.6% (95% CI: -7.7, -1.5%, p = .01), other cataract/intraocular lens surgeries decreased yearly by an average of 8.4% (95% CI: -10.1, -6.6%, p < .001), anterior vitrectomies decreased yearly by an average of 12.5% (95% CI: -14.9, -10.1%, p < .001), and laser capsulotomies increased yearly by an average of 6.0% prior to 2019 and then decreased by 3.0% for an overall average yearly increase of 5.3% (95% CI: 4.5, 6.2%, p < .001). As assistant, average numbers logged in all ACGME minimum categories showed decreasing trends. CONCLUSIONS: Over the last decade, the average numbers of phacoemulsification and laser capsulotomies logged by residents as primary surgeon increased while other ACGME cataract minimum procedures decreased. Surgical volume in 2019-20 was lower due to the coronavirus disease-19 pandemic but higher than from 2009 to 2013.

Keratoplasty in the United States: Trends and Indications From 2015 to 2020.

PURPOSE: The aim of this study was to report trends in keratoplasty techniques and indications in the United States from 2015 to 2020. METHODS: This retrospective review of annual reports from the Eye Bank Association of America assessed domestic corneal graft distribution and surgical indication data for various types of keratoplasty. Trends in procedure volume and indications from 2015 to 2020 were analyzed using the Cochran-Armitage test. RESULTS: The total number of corneal transplants increased from 47,903 in 2015 to 49,143 in 2019, with a decline to 42,257 in 2020, most likely due to COVID-19. Penetrating keratoplasty (PK) volume decreased from 2015 to 2020 (19,160-15,402, 40% to 36.4%, P < 0.001), continuing a trend from the previous decade. Descemet membrane endothelial keratoplasty as a percentage of all keratoplasty procedures increased (9.8%-27.8%, P < 0.001), whereas Descemet stripping automated endothelial keratoplasty (47%-33.9%, P < 0.001) and anterior lamellar keratoplasty (ALK) decreased (2.3%-1.2%, P < 0.001).From 2017 to 2020, repeat corneal transplant was the most common specific indication for PK while ectasias/thinnings decreased in prevalence (15.6%-11.5%, P < 0.001). Ectasias/thinnings and endothelial dystrophy remained the leading indications for ALK and endothelial keratoplasty, respectively. CONCLUSIONS: From 2015 to 2020, keratoplasty trends in the United States showed a continuation of the decrease in PK and increase in Descemet membrane endothelial keratoplasty observed in the previous decade. The most common domestic indications from 2017 to 2020 have been repeat corneal graft, endothelial dystrophy, and ectasias/thinnings for PK, EK, and ALK, respectively.

Patient Use of Dietary Supplements, Home Monitoring, or Genetic Testing for Nonneovascular Age-Related Macular Degeneration.

Purpose: This work evaluated the use and type of dietary supplements and home monitoring for nonneovascular age-related macular degeneration (AMD), as well as the prevalence of genetic testing among patients with AMD. Methods: A cross-sectional study was conducted of 129 participants older than 50 years who completed self-administered questionnaires regarding usage and type of dietary supplements and home monitoring, as well as the participants' use of genetic testing for AMD. Results: Of 91 participants with AMD, 83 (91.2%) took vitamins, including 55 (60.4%) who used an Age-Related Eye Disease Study (AREDS) or AREDS2 formulation. Of 38 without AMD, 31 (81.6%) took vitamins (difference from participants with AMD = 9.6% [95% CI, 0%-23.2%]), including 2 on an AREDS formulation. Among 82 participants with AMD who were AREDS candidates (intermediate or advanced AMD in 1 or both eyes), 51 (62.2%; 95% CI, 51.7%-72.7%) took an AREDS or AREDS2 formulation, and 31 (37.8%) did not (5 were unsure). Additionally, 50 (61.0%; 95% CI, 50.4%-71.6%) AREDS candidates did some type of home monitoring. Only 1 (1.2%; 95% CI, 0%-3.6%) underwent genetic testing for AMD. Among 9 with AMD who were not AREDS candidates, 4 (44.4%) used an AREDS formulation, 4 (44.4%) did not, and 1 (11.1%) was unsure; only 1 (11.1%) of these 9 performed home monitoring. Conclusions: Despite similar results from past surveys and AREDS2 data supporting supplement use in 2013 and home monitoring in 2014, these findings suggest about one-third of AREDS candidates do not do so, providing further support for improving education regarding appropriate supplement and home monitoring usage. Genetic testing for AMD also appears infrequent.

Visual Acuity Reporting in Clinical Research Publications.

Importance: Visual acuity results in publications typically are reported in Snellen or non-Snellen formats or both. A study in 2011 suggested that many ophthalmologists do not understand non-Snellen formats, such as logarithm of the Minimum Angle of Resolution (logMAR) or Early Treatment Diabetic Retinopathy Study (ETDRS) letter scores. As a result, some journals, since at least 2013, have instructed authors to provide approximate Snellen equivalents next to non-Snellen visual acuity values. Objective: To evaluate how authors currently report visual acuity and whether they provide Snellen equivalents when their reports include non-Snellen formats. Design: From November 21, 2016, through December 14, 2016, one reviewer evaluated visual acuity reporting among all articles published in 4 ophthalmology clinical journals from November 2015 through October 2016, including 3 of 4 journals that instructed authors to provide Snellen equivalents for visual acuity reported in non-Snellen formats. Main Outcomes and Measures: Frequency of formats of visual acuity reporting and frequency of providing Snellen equivalents when non-Snellen formats are given. Results: The 4 journals reviewed had the second, fourth, fifth, and ninth highest impact factors for ophthalmology journals in 2015. Of 1881 articles reviewed, 807 (42.9%) provided a visual acuity measurement. Of these, 396 (49.1%) used only a Snellen format; 411 (50.9%) used a non-Snellen format. Among those using a non-Snellen format, 145 (35.3%) provided a Snellen equivalent while 266 (64.7%) provided only a non-Snellen format. Conclusions and Relevance: More than half of all articles in 4 ophthalmology clinical journals fail to provide a Snellen equivalent when visual acuity is not in a Snellen format. Since many US ophthalmologists may not comprehend non-Snellen formats easily, these data suggest that editors and publishing staff should encourage authors to provide Snellen equivalents whenever visual acuity data are reported in a non-Snellen format to improve ease of understanding visual acuity measurements.

Autophagy induction causes a synthetic lethal sensitization to ribonucleotide reductase inhibition in breast cancer cells.

Macroautophagy can promote cellular survival or death depending on the cellular context and its extent. We hypothesized that autophagy induction would synergize with a therapeutic agent targeting the autophagic cargo. To test this hypothesis, we treated breast cancer MDA-MB-231 cells with tamoxifen (TMX), which induces autophagy through an estrogen receptor-independent pathway. Induction of autophagy reduced cellular levels of RRM2, a subunit of ribonucleotide reductase (RR), the rate limiting enzyme in the production of deoxyribonucleotide triphosphates (dNTPs). This autophagy inducer was combined with COH29, an inhibitor developed in our laboratory that targets RR through a novel mechanism. The combination therapy showed synergistic effects on cytotoxicity in vitro and in an in vivo xenograft model. This cytotoxicity was blocked by knockdown of the autophagy protein ATG5 or addition of chloroquine, an autophagy inhibitor. The combined therapy also induced dNTP depletion and massive genomic instability, leading us to hypothesize that combining autophagy induction with RR inhibition can lead to mitotic catastrophe in rapidly dividing cells. We propose that this TMX + COH29 combined therapy may have clinical benefit. Furthermore, autophagy induction may be a general mechanism for augmenting the effects of chemotherapeutic agents.
