RESUMEN

OBJECTIVE: This study aimed to assess whether the research output of medical students who matched into a Canadian ophthalmology residency program influences their subsequent research productivity during residency, decision to pursue a fellowship, or engagement in academic practice. DESIGN: Retrospective database review. PARTICIPANTS: A total of 369 trainees commencing ophthalmology residency from 2004 to 2015 at 15 residency programs. METHODS: Each trainee's publication record was queried in Scopus before and after the date they started residency. Multiple public sources were searched to identify fellowship placement and the type of subsequent practice (i.e., academic or community). Predictors of research productivity during residency, fellowship, and practice setting were assessed using multivariable regression analyses. RESULTS: Trainees with pre-residency publications (n = 187) demonstrated significantly higher research productivity during residency than those without pre-residency publications (n = 182), with a mean of 5.17 ± 5.97 versus 1.60 ± 2.38 publications on any topic (p < 0.001). Pre-residency research output was a predictor of research productivity during residency (relative risk = 1.17; 95% CI, 1.09-1.27; p < 0.001), pursuing fellowship (odds ratio, 2.9; 95% CI, 1.74-4.83), and an academic career (odds ratio = 1.85; 95% CI, 1.07-3.2). CONCLUSION: Pre-residency research output is a significant predictor of research productivity during residency and subsequent career choices, suggesting that pre-residency publishing reflects a propensity toward an academic trajectory. Residency publication count moderates this association, underscoring the role of the residency program environment in fostering research productivity. Addressing barriers such as mentorship, funding, and curriculum may be key to incentivizing trainees to pursue academic medicine.

RESUMEN

PURPOSE: Morvan syndrome (MoS) is a neurologic disorder belonging to a spectrum of autoimmune encephalitis, Contactin-associated protein-like 2 (Caspr2) antibody syndrome. We report a case of bilateral panuveitis associated with MoS. METHODS: Case report and review of the literature. RESULTS: A 57-year-old male with Morvan syndrome presented with painless vision loss and floaters. Initial visual acuities were 20/50 and 20/60. Hallmarks of this uveitis included persistently active vitritis, and nonhemorrhagic retinitis with nonperfusion and neovascularization. Uveitis consistently flared with attempted immunosuppressive tapers. Vision deteriorated to count fingers (2 ft) OU over 2.5 years despite corticosteroids, mycophenolate mofetil, intravenous immunoglobulin, adalimumab, and rituximab. Explanations for reduced final visual acuity included macular atrophy, disruption of retinal architecture, epiretinal membrane, vitritis, and cataract. CONCLUSIONS: This case constitutes the first report of uveitis associated with MoS and Caspr2 antibody syndrome, raising the question of autoimmunity targeting the retinal inner and/or outer plexiform layers.

RESUMEN

OBJECTIVE: To assess the impact of ophthalmology resident research and its relationship to subsequent practice. DESIGN: Cross-sectional study. PARTICIPANTS: Three hundred and twenty residents of Canadian ophthalmology programs graduating between 2009 and 2020. METHODS: Bibliometric data were obtained for each resident from Scopus. Indices of scholarly productivity included number of publications, h-index, m-quotient, and total citations. Demographic and career data were obtained from faculty listings and professional and regulatory web sites. Career outcomes included location and subspecialty of fellowship training and type of ultimate practice (academic vs community). RESULTS: In total, 208 of 320 graduates (65%) published at least 1 peer-reviewed article during residency. Bibliometric indices, including numbers of papers, h-index, and total citations, were significantly higher for male residents and residents who pursued academic and subspecialized practices. No significant trends were seen regarding scholarly productivity and fellowship match outcomes (e.g., location and subspecialty of fellowship). The bulk of resident research projects was of lower tiers of evidence, including retrospective studies (n = 111) and case reports (n = 108). Five-year scholarly impact of resident research decreased over time (h-index, m = -0.14; p < 0.01) despite stable publication volumes. CONCLUSIONS: Greater scholarly activity in residency corresponds to more academic and subspecialized practices but is not associated with type of fellowship. The impact of resident research declined between 2009 and 2020. Sex-based disparities exist.

RESUMEN

PURPOSE: To validate the Iris Glare, Appearance, and Photophobia (Iris GAP) questionnaire, a new symptom-based and appearance-based quality-of-life measure for patients with iris defects. SETTING: Single tertiary glaucoma clinic in Toronto, Ontario, Canada. DESIGN: Prospective cohort study. METHODS: Patients with varying degrees of iris defects were enrolled. Patients completed the Iris GAP questionnaire and the glare and driving subscales of the Refractive Status and Vision Profile (RSVP) questionnaire. Test-retest reliability, defined by Cronbach α and intraclass correlation coefficients (ICCs), was evaluated with repeat testing 2 weeks later. RESULTS: The study included 73 patients with iris defects, 68 controls with no iris defects, 77 patients with peripheral iridotomies (PIs) or transillumination defects (TIDs), and 22 patientswith surgically repaired irides (n = 22). Iris GAP scores ranged from 0 to 32 with a 97% completion rate. Iris GAP had high test-retest reliability (Cronbach α = 0.866, ICC = 0.953, P < .0005). Iris GAP scores were reliably distinguishable between patients with iris defects, repaired iris defects, and PIs and TIDs and controls (1-way analysis of variance, P < .0005). In pairwise comparisons, the major defect group had statistically significant higher scores than any of the other groups ( P < .005 for each). The control and repaired groups had the lowest scores, whereas the PI/TID group had intermediate scores. 9 patients underwent iris repair between tests and had a mean difference of 8.2 ± 6.2 points between their preoperative and postoperative scores ( P = .004). Iris GAP scores positively correlated with RSVP scores ( R2 = 0.73). CONCLUSIONS: Iris GAP can reliably evaluate symptomatology and patient-reported appearance in patients with iris defects.

RESUMEN

STUDY DESIGN: Systematic review. Surgical decompression for degenerative cervical myelopathy (DCM) is associated with perioperative complications, including difficulty or discomfort with swallowing (dysphagia) as well as changes in sound production (dysphonia). This systematic review aims to (1) outline how dysphagia and dysphonia are defined in the literature and (2) assess the quality of definitions using a novel 4-point rating system. METHODS: An electronic database search was conducted for studies that reported on dysphagia, dysphonia or other related complications of DCM surgery. Data extracted included study design, surgical details, as well as definitions and rates of surgical complications. A 4-point rating scale was developed to assess the quality of definitions for each complication. RESULTS: Our search yielded 2,673 unique citations, 11 of which met eligibility criteria and were summarized in this review. Defined complications included odynophagia (n = 1), dysphagia (n = 11), dysphonia (n = 2), perioperative swelling complications (n = 2), and soft tissue swelling (n = 3). Rates of dysphagia varied substantially (0.0%-50.0%) depending on whether this complication was patient-reported (4.4%); patient-reported using a modified Swallowing Quality of Life questionnaire (43.1%) or the Bazaz criteria (8.8%-50.0%); or diagnosed using an extensive protocol consisting of clinical assessment, a bedside swallowing test, evaluation by a speech and language pathologist and a modified barium swallowing test/fiberoptic endoscopy (42.9%). The reported incidences of dysphonia also ranged significantly from 0.6% to 38.0%. CONCLUSION: There is substantial variability in reported rates of dysphagia and dysphonia due to differences in data collection methods, diagnostic strategies, and definitions. Consolidation of nomenclature will improve evaluation of the overall safety of surgery.

RESUMEN

PURPOSE: To characterize presentations, characteristics and outcomes of uveitis in Vogt-Koyanagi-Harada (VKH) syndrome in a North American First Nations (FN) population. METHODS: Charts of 27 Canadian FN patients with VKH uveitis were retrospectively reviewed to characterize demographics, disease characteristics, management, complications and visual outcomes. RESULTS: Average age at uveitis onset was 30.9 ± 13.8 years. Twenty-six patients 10 (96.3%) were female. Nine patients (33.3%) demonstrated complete VKH, 8 (29.6%) incomplete, and 10 (37%) probable VKH. Systemic associations included integumentary (19 patients, 70%), neurologic (17 patients, 63%), and auditory (13 patients, 48%) findings. Initial rates of mild, moderate and severe vision loss were 19 eyes (35.2%), 12 eyes (22.2%), and 23 eyes (42.6%), respectively, compared with final rates of 19 eyes (35.2%), 14 eyes (25.6%) and 21 eyes (38.9%), respectively. Average change in visual acuity was 15 0.1 ± 6.3 Snellen lines. Rates of immunomodulatory therapy (IMT) use (10 patients, 37%) fell short of targets. CONCLUSIONS: VKH may cause potentially severe uveitis in this population. Comorbidities including tuberculosis and diabetes, in addition to unique cultural, linguistic and geographic factors, may necessitate complex, individualized management strategies.

RESUMEN

OBJECTIVE: To outline the current impact of Canadian ophthalmology and vision science research as measured by novel research metrics. DESIGN: Cross-sectional survey. PARTICIPANTS: All Canadian ophthalmologists (n = 687) and vision scientists (n = 119) with an online bibliometric profile and academic appointment at a major ophthalmology training centre were included. METHODS: Faculty lists of Canada's 15 major academic ophthalmology departments were obtained. Faculty names, appointments, sex, and educational background were recorded. Elsevier's Scopus database was used to calculate H-index, m-quotient, and total citations for each faculty member. Details around grant funding were obtained through the Canadian Institutes of Health Research (CIHR) Funding Decisions Database. RESULTS: Average H-indices were 7.42 ± 7.98 for ophthalmologists and 23.78 ± 15.25 for vision scientists. Higher academic appointment was correlated with higher h-indices and m-quotients (p <0.0001 for both). Most academic departments had significantly more males than females (avg. 71% male, 29% female); however, more equal ratios were seen in faculties in Quebec. No significant differences in research impact were identified between male and female ophthalmologists when controlled for academic appointment and career stage (p > 0.05). In clinical ophthalmology research, the top three departments with the highest average H-indices were Western University, the University of Toronto, and Dalhousie University. The University of British Columbia, Université de Montréal, and McGill University received the most funding from the CIHR in the last 10 years. CONCLUSION: This study highlights the current scope of ophthalmology and vision science research in Canada. Important trends were identified in research productivity across academic rank, sex, and clinical subspecialty.

RESUMEN

STUDY DESIGN: Systematic review. OBJECTIVE: This review aims to (1) outline how neurological complications and disease progression are defined in the literature and (2) evaluate the quality of definitions using a novel four-point rating system. SUMMARY OF BACKGROUND DATA: Degenerative cervical myelopathy (DCM) is a progressive, degenerative spine disease that is often treated surgically. Although uncommon, surgical decompression can be associated with neurological complications, such as C5 nerve root palsy, perioperative worsening of myelopathy, and longer-term deterioration. Unfortunately, important questions surrounding these complications cannot be fully addressed due to the heterogeneity in definitions used across studies. Given this variability, there is a pressing need to develop guidelines for the reporting of surgical complications in order to accurately evaluate the safety of surgical procedures. METHODS: An electronic database search was conducted in MEDLINE, MEDLINE in Process, EMBASE and Cochrane Central Register of Controlled Trials for studies that reported on complications related to DCM surgery and included at least 10 surgically treated patients. Data extracted included study design, surgical details, as well as definitions and rates of surgical complications. A four-point rating scale was developed to assess definition quality for each complication. RESULTS: Our search yielded 2673 unique citations, 42 of which met eligibility criteria and were summarized in this review. Defined complications included neurological deterioration, late onset deterioration, perioperative worsening of myelopathy, C5 palsy, nerve root or upper limb palsy or radiculopathy, surgery failure, inadequate decompression and progression of ossified lesions. Reported rates of these complications varied substantially, especially those for neurological deterioration (0.2%-33.3%) and progression of ossified lesions (0.0%-86.7%). CONCLUSION: Reported incidences of various complications vary widely in DCM surgery, especially for neurological deterioration and progression of ossified lesions. This summary serves as a first step for standardizing definitions and developing guidelines for accurately reporting surgical complications. LEVEL OF EVIDENCE: 2.

RESUMEN

BACKGROUND: Ossification of the posterior longitudinal ligament (OPLL) is defined as ectopic bone formation within the posterior longitudinal ligament. Although various OPLL features (including the extent, shape, and thickness of the OPLL as well as the presence of dural ossification) have been defined in the literature, we are not aware of any systematic reviews that have summarized the associations between these features and clinical outcomes following surgery. The objective of the present study was to conduct a systematic review of the literature to determine whether OPLL characteristics are predictive of outcome in patients undergoing surgery for the treatment of cervical myelopathy. METHODS: An extensive search was performed using 4 electronic databases: MEDLINE, MEDLINE In-Process, Embase, and the Cochrane Central Register of Controlled Trials. Our search terms were OPLL and cervical. We identified studies in English or Japanese that evaluated the association between cervical OPLL features and surgical outcome. The overall body of evidence was assessed with use of a scoring system developed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group with recommendations from the Agency for Healthcare Research and Quality (AHQR). The present systematic literature review is formatted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS: The search yielded a total of 2,318 citations. A total of 28 prognostic cohort studies were deemed relevant following a rigorous review process. Among them, only 7 retrospective studies involved a multivariate analysis that controlled for potential confounding variables. Sample sizes ranged from 47 to 133 patients. The main outcome was the postoperative Japanese Orthopaedic Association (JOA) score and/or recovery rate in 6 studies and the Nurick grade in 1. Of these, 2 were rated as Level-II evidence and 5 were rated as Level-III evidence. On the basis of our results, there was low evidence that patients with a hill-shaped ossification have a worse postoperative JOA score following laminoplasty than those with a plateau-shaped lesion; low evidence that the space available for the spinal cord cannot predict postoperative JOA scores; moderate evidence that there is no association between the occupying ratio and improvement on the Nurick scale; and insufficient evidence to determine the association between JOA outcomes and the type of OPLL, the presence of dural ossification, and the occupying ratio. CONCLUSIONS: Patients with hill-shaped OPLL have a worse postoperative JOA score than those with plateau-shaped ossification after laminoplasty. Because of limited evidence, it is unclear whether the occupying ratio, the type of OPLL, and the presence of dural ossification are predictive of surgical outcomes following either anterior or posterior decompression. A limited number of studies have used a multivariate analysis to evaluate the association between clinical outcomes and OPLL features. Additional studies representing high-quality evidence are needed. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
