RESUMEN

PURPOSE: To provide relative citation ratio (RCR) benchmark data for the field of glaucoma. DESIGN: Cross-sectional bibliometric analysis. SUBJECTS: Fellowship-trained glaucoma faculty at Accreditation Council for Graduate Medical Education-accredited institutions. METHODS: Glaucoma faculty were individually indexed using the National Institutes of Health (NIH) iCite website. Publication count, mean RCR score, and weighted RCR score were collected for each author between May and August 2023 and included PubMed-listed articles from 1980 to 2023. Data were compared by sex, career duration, academic rank, and acquisition of a Doctor of Philosophy (PhD). MAIN OUTCOME MEASURES: Total number of publications, mean RCR value, and weighted RCR value. RESULTS: Five hundred twenty-six academic glaucoma specialists from 113 institutions were indexed. These physicians produced highly impactful research with a median publication count of 13 (interquartile range [IQR] 4-38), median RCR of 1.41 (IQR 0.97-1.98), and median weighted RCR of 16.89 (4.80-63.39). Academic rank, career duration, and having a PhD were associated with increased publication count, mean RCR, and weighted RCR. Publication count and weighted RCR differed significantly by sex; however, no difference was observed with mean RCR. CONCLUSIONS: Current academic glaucoma specialists have high mean RCR values relative to the NIH standard RCR value of 1. This benchmark data serve as a more accurate gauge of research impact within the glaucoma community and can be used to inform self, institutional, and departmental evaluations. Additionally, the mean RCR may provide an accurate metric for quantifying research productivity among historically underrepresented groups that are disadvantaged by time-dependent factors such as number of publications.

RESUMEN

IMPORTANCE: Ocular surface squamous neoplasia (OSSN) is a spectrum of malignancies that generally includes conjunctival intraepithelial neoplasia (CIN) and squamous cell carcinoma (SCC). OSSN can be treated with topical therapies including interferon α-2b (IFN), mitomycin C (MMC), or 5-fluorouracil 1% (5FU). Recently, due to unavailability of IFN and toxicity associated with MMC, therapy has shifted towards 5FU. OBJECTIVE: Herein, we compare the use of 5FU 1% as a primary versus (vs) secondary treatment regimen in eyes with moderate to extensive OSSN. DESIGN SETTING AND PARTICIPANTS: Retrospective cohort study of 73 consecutive patients with unilateral moderate to extensive OSSN treated at a single tertiary ocular oncology center from 2016 to 2023. Mean follow up time was 478.2 days overall, with 283.0 days for primary 5FU group and 860.3 days for secondary 5FU group. INTERVENTION: Topical 5FU 1% 4 times daily for 2 weeks with option for 2-weekly extension until tumor control, either as primary treatment or as secondary treatment to surgical resection, topical IFN or topical MMC, or cryotherapy. MAIN OUTCOMES: Outcome measures included tumor response, need for additional surgery, complications, and visual outcomes. RESULTS: A comparison (primary vs secondary treatment) revealed no difference in mean tumor basal dimension (19.6 vs 17.2 mm, P = 0.46), thickness (3.7 vs 3.4 mm, P = 0.64), or tumor extent (4.4 vs 4.5 clock hours, P = 0.92). The primary treatment group showed greater complete tumor control (77% vs 38%, P = 0.04). Multivariable analysis comparison (primary vs secondary treatment) showed primary treatment more likely to achieve complete tumor control (P = 0.01). There was no difference in the complication rate from 5FU treatment between the groups. There was no difference in visual outcome, and no tumor-related metastasis (0%) or death (0%). CONCLUSION AND RELEVANCE: Topical 5FU 1% is efficacious and safe as a primary or secondary treatment for moderate to extensive OSSN. Tumors treated with primary 5FU 1% demonstrated more complete resolution. In patients with moderate to extensive OSSN, primary treatment with topical 5FU 1% may be warranted.

RESUMEN

PURPOSE: The purpose of this study was to provide relative citation ratio (RCR) benchmark data for cornea and external diseases specialists. DESIGN: This is a cross-sectional bibliometric analysis. SUBJECTS: Subjects included were fellowship-trained cornea and external diseases faculty at Accreditation Council for Graduate Medical Education-accredited institutions in the United States. METHODS: Academic specialists were indexed using the National Institutes of Health iCite Web site. Publication count, mean RCR score, and weighted RCR score were obtained between October 2022 and January 2023 by examining PubMed-listed publications from 1980 to 2022. Data were compared by sex, career duration, academic rank, and acquisition of a Doctor of Philosophy. MAIN OUTCOME MEASURES: The main outcome measures were publication count, mean RCR value, and weighted RCR value. RESULTS: The cohort included 602 specialists from 112 Accreditation Council for Graduate Medical Education-accredited institutions. These clinician-scientists produced highly impactful research with a median publication count of 15 (interquartile ranges 4-41), median RCR of 1.4 (interquartile ranges 0.91-1.88), and median-weighted RCR of 20.28 (5.3-66.69). Both academic rank and career length were associated with greater publication count and RCR values. Male sex was also associated with greater publications counts and RCR scores compared with female faculty. Acquisition of a Doctor of Philosophy was associated with greater publication counts and weighted RCR scores but no difference in mean RCR scores. CONCLUSIONS: Academic cornea and external diseases specialists conduct high-impact research, with a median RCR of 1.4, exceeding the NIH standard value of 1. These data provide RCR benchmark data for the field to inform self, institutional, and departmental evaluations. These results also highlight a significant gender disparity in the field necessitating efforts to increase female representation and ensure equal opportunities.

RESUMEN

Purpose: To present a patient with cystoid macular edema (CME) associated with ponesimod use and offer suggestions for the management of this condition. Methods: A case report is presented. Results: A 75-year-old woman with relapsing-remitting multiple sclerosis had an unremarkable baseline ophthalmic examination prior to starting ponesimod. At her 9-month follow-up, an examination showed the development of CME in the left eye. The patient's macular edema fully resolved after transitioning off ponesimod to an alternative systemic medication and starting treatment with a topical corticosteroid and nonsteroidal anti-inflammatory drug. Conclusions: To our knowledge, this is the first case report discussing the entity and management of ponesimod-associated macular edema. Ponesimod cessation and concomitant topical therapy can result in successful resolution of macular edema.

RESUMEN

PURPOSE: The aim of this study is to evaluate 90-day outcomes and complications following radial head arthroplasty (RHA) for Mason Type III and IV radial head fractures (RHFs) and determine factors predisposing patients to early complications and revision surgery. METHODS: Patients undergoing RHA for Mason Type III and IV RHFs were identified retrospectively from an institutional database. Postoperative complications, reoperations, elbow range of motion, radiographs and concomitant injuries on the ipsilateral upper extremity were reviewed. Additionally, injuries were sub-classified as low-energy trauma (LET) or high-energy trauma (HET). Univariate logistic regression was performed to evaluate the risk for complications using patient factors not limited to the presence of concomitant ligamentous or bony injuries. P values < 0.05 were considered statistically significant. RESULTS: Seventy four patients were included in our study with an average follow-up time of 12.7 months. Complications within 90-days of operation occurred in 8.1% of patients: heterotopic ossification (4.1%), superficial wound dehiscence (2.7%), and posterior interosseous nerve palsy (1.4%). No patients required readmission or revision surgery in the 90-day postoperative period. Univariate regression analysis did not demonstrate a significant association between diabetes, ASA status, HET versus LET, or the presence of concomitant injury. Concomitant injuries were found in 92% of patients. CONCLUSION: Radial head arthroplasty for RHFs demonstrates a low complication rate in the short-term. Diabetes, ASA class, high versus low energy trauma, and presence of concomitant injury were not found to be associated with higher complication rates in the 90-day postoperative period. LEVEL OF EVIDENCE: Level of evidence IV, retrospective case series.

RESUMEN

Propranolol is a widely used beta blocker that consists of a racemic mixture of R and S stereoisomers. Only the S stereoisomer has significant activity against the beta-adrenergic receptor. A fortuitous clinical observation was made in an infant who received propranolol for cardiac disease, and regression of a hemangioma of infancy was noted. This has led to the widespread use of propranolol for the treatment of large and life-threatening hemangiomas of infancy. Infants receiving propranolol require monitoring to ensure that they do not suffer from side effects related to beta blockade. The exact mechanism of activity of propranolol in hemangioma of infancy is unknown. In this study, we treated hemangioma stem cells with both beta blockade active S- and inactive R-propranolol and looked for genes that were coordinately regulated by this treatment. Among the genes commonly downregulated, Angiopoietin-like 4 (ANGPTL4) was among the most regulated. We confirmed that propranolol isomers downregulated ANGPTL4 in endothelial cells, with greater downregulation of ANGPTL4 using the beta blockade inactive R-propranolol. ANGPTL4 is present in human hemangiomas of infancy. Finally, R-propranolol inhibited the growth of bEnd.3 hemangioma cells in vivo. The implication of this is that hemangioma growth can be blocked without the side effects of beta blockade. Given that humans have been exposed to racemic propranolol for decades and thus to R-propranolol, clinical development of R-propranolol for hemangiomas of infancy and other angiogenic diseases is warranted.
