RESUMEN

BACKGROUND/PURPOSE: To describe several modified approaches to remove retained silicone oil droplets on intraocular lens (IOLs). METHODS: Four novel techniques for removing retained silicone oil droplets on IOLs were described. RESULTS: All four techniques led to an improved IOL with a good view to the posterior segment. No intraoperative or long-term postoperative complications have been seen in any of these eyes. These modified approaches are safe, efficient, low cost, and use existing vitreoretinal operating room supplies to add to the vitreoretinal surgeon's armamentarium to clear retained IOL silicone droplets. CONCLUSION: It is advocated for having multiple techniques at the disposal of the vitreoretinal surgeon to address retained silicone oil on IOLs. Being able to use multiple techniques may not be superior than a single approach but is often necessary to accomplish the surgical goal of removing these adherent droplets.

RESUMEN

BACKGROUND: Recently, histologic grade was removed from salivary tumor nomenclature by the WHO to include disease of higher grade. One such entity, cribriform adenocarcinoma (CAC), is an aggressive group of polymorphous adenocarcinoma (PAC), with frequent nodal metastasis and locoregional recurrence. We aim to examine the biologic behavior of this disease as compared with the PAC general cohort inclusive of all subtypes. METHODS: A systematic review of the literature on polymorphous adenocarcinoma and cribriform adenocarcinoma was completed. A descriptive analysis was performed for the following predictor variables: nodal and distant metastasis, in addition to recurrence. The outcome variables, disease free recurrence, and disease specific survival, where plotted using Kaplan-Meier curves. RESULTS: PAC and CAC both show median age of diagnosis in the sixth decade of life and a female predominance. CAC occurs most frequently in the tongue and PAC in the palate. The 2 groups show a similar biologic behavior in regards to incidence of distant metastasis (4.1 vs 5.5%), recurrence (12.5 vs 17.8%), and death from disease (3 vs 2.7%). However, there was an increased incidence of nodal metastasis in CAC (53%) as compared with that in PAC of all subtypes (14%). CONCLUSIONS: CAC exhibits more aggressive biologic behavior as compared with the PAC cohort. Although CAC is not an officially recognized entity, these tumors likely comprise a significant portion of the cases of PAC with poor outcomes and are deserving of attention and consideration for escalation in oncologic treatment.

RESUMEN

Primary uveal melanoma is rare and affects approximately 8,000 persons per year worldwide. This malignancy can involve the iris, ciliary body, and choroid. Of these three structures, the iris is the least commonly affected site, representing only 4% of all uveal melanomas. Iris melanoma can arise from iris melanocytic nevus, iris melanocytosis, or de novo. In a longitudinal study of 1,611 patients with iris nevus, transformation into melanoma, using Kaplan-Meier estimates, was found in 2.6% by five years and in 4.1% by 10 years. The factors that predicted growth of iris melanocytic nevus into melanoma are denoted by a letter (ABCDEF) guide: A for age ≤40 years old at presentation (hazard ratio [HR] = 3, P = .01), B for blood (hyphema) (HR = 9, P < .0004), C for clock hour of tumor inferiorly (tumor location) (HR = 9, P = .03), D for diffuse flat tumor configuration (HR = 14, P = .02), E for ectropion uveae (HR = 4, P = .002), and F for feathery ill-defined margins (HR = 3, P = .02). At diagnosis, iris melanoma has a mean cross-sectional diameter of 5.5 mm and thickness of 2.1 mm, often with tumor seeding (28%) and secondary glaucoma (35%). We provide a comprehensive review of iris nevus and melanoma to explore relevant demographic and clinical data, risk factors for tumor growth, management, and prognosis, with the hope that clinicians will be more comfortable in understanding this rare malignant condition.

RESUMEN

OBJECTIVES: To determine clinical features and outcomes of posterior scleritis masquerading as uveal melanoma following vaccination against COVID-19 and/or COVID-19 infection. SUBJECTS/METHODS: All patients with posterior scleritis referred to our service to rule out intraocular tumour between February 2021 and June 2022, who previously had COVID-19 vaccination and/or infection (n = 8). A retrospective detailed review of patient charts and imaging was carried out. RESULTS: Previous COVID-19 vaccination was documented in 6 patients (75%) and previous COVID-19 infection and vaccination in 2 patients (25%). Demographic features included mean age of 59 years (median 68, range 5-86 years), white race (n = 7, 87%), and male sex (n = 5, 63%). Mean visual acuity at presentation was 0.24 LogMAR (median 0.18, range 0.0-0.70). The main presenting symptom was blurred vision with pain (n = 5, 63%). Features that suggested scleritis and not uveal melanoma included pain (n = 6, 75%), anterior scleritis (n = 3, 38%), disc oedema (n = 1, 13%), choroidal detachment (n = 3, 38%), choroidal folds (n = 3, 38%), diffusely thickened scleral wall on ultrasonography (n = 2, 25%), Tenon's oedema (n = 5, 63%), and scleral nodule with medium/high internal reflectivity on ultrasonography (n = 4, 50%). Follow-up information at mean of 2 months (range 0.25-7 months) revealed visual acuity at date last seen was mean 0.30 LogMAR (median 0.29, range 0.0-0.54). By 2 months, resolution of "tumour" was noted in 5/6 (83%) patients with follow-up. CONCLUSIONS: Posterior scleritis following COVID-19 vaccination and/or infection can masquerade as choroidal melanoma. At 2 months duration, partial or complete resolution of features with minimal visual consequence was noted.

RESUMEN

BACKGROUND: Ameloblastoma may present a significant treatment challenge in the locally advanced, recurrent and metastatic setting. Comprehensive genomic profiling (CGP) can identify targetable genomic alterations to aid in treatment. METHODS: Ameloblastoma samples were sequenced using hybrid-capture based sequencing. A systematic literature review was performed to examine outcomes in studies employing targeted treatment in ameloblastoma. RESULTS: We reviewed 14 cases of Ameloblastoma using CGP. There were six patients with activating BRAF mutations, five with PIK3CA, five with SMO, four with FGFR2, one with EGFR, and one with ROS1. All cases were MSI stable and the median TMB was 2.5 mutations/Mb. A separate literature review of clinical outcomes in ameloblastoma showed a predominance of at least partial response to targeted treatment (7/12 cases). CONCLUSION: CGP is helpful in identifying specific driver mutations in patients with complex ameloblastoma. Targeted treatment has been employed with success in achieving treatment response.

RESUMEN

BACKGROUND/PURPOSE: The purpose of this study was to analyze Descemet stripping endothelial keratoplasty (DSEK) outcomes and develop a nomogram to compute the probability of 3- and 5-year DSEK graft survival based on risk factors. STUDY DESIGN/METHODS: The medical records of 794 DSEK procedures between January 1, 2008, and August 1, 2019, were retrospectively reviewed to identify 37 variables. We also evaluated for the presence of corneal graft failure, defined as irreversible and visually significant graft edema, haze, or scarring. Variables were assessed by multivariable Cox models, and a nomogram was created to predict the probability of 3- and 5-year graft survival. RESULTS: Graft failure occurred in 80 transplants (10.1%). The strongest risk factors for graft failure included graft detachment [hazard ratio (HR) = 4.46; P < 0.001], prior glaucoma surgery (HR = 3.14; P = 0.001), and glaucoma (HR = 2.23; P = 0.018). A preoperative diagnosis of Fuchs dystrophy was associated with a decreased risk of graft failure (HR = 0.47; P = 0.005) compared with secondary corneal edema. Our nomogram has a concordance index of 0.75 (95% confidence interval, 0.69 to 0.81), which indicates that it may predict the probability of graft survival at 3 and 5 years with reasonable accuracy. We also analyzed graft rejection, which occurred in 39 cases (4.9%). The single risk factor found to be significantly associated with graft rejection was prior glaucoma surgery (HR = 2.87; P = 0.008). CONCLUSIONS: Our nomogram may accurately predict DSEK graft survival after 3 and 5 years based on 4 variables. This nomogram will empower surgeons to share useful data with patients and improve collective clinical decision-making.

RESUMEN

Purpose Despite easing restrictions on social distancing and travel since the beginning of coronavirus disease 2019 pandemic, virtual interviews remain a widely used format for ophthalmology fellowship interviews. This study aims to evaluate the relative benefits and drawbacks of in-person versus virtual interviews during a cycle where both formats were prevalent. Methods A prospective cross-sectional study surveyed all fellowship applicants ( N = 311) who applied to Wills Eye Hospital and Bascom Palmer Eye Institute during the 2022 to 2023 application cycle. Results A total of 59 (19%) applicants responded to the survey, with the majority being male (53.0%) and between the ages of 20 and 35 (91.3%). There was no statistically significant difference between the number of virtual and in-person interviews attended or the total number of interviews attended. The highest ranked limitations of the virtual interview process were limited exposure to details of the program structure, limited opportunity to exhibit applicants' strengths to the program, and limited exposure to the fellows. The highest ranked strengths were less pressure during interviews, greater scheduling flexibility, and ability to interview at more fellowship programs. The highest ranked limitations of the in-person interview process were more pressure during interviews, inability to interview at all desired fellowship programs, and decreased scheduling flexibility. The highest ranked strengths based on median rankings were greater exposure to details of the program structure, greater ability to exhibit an applicant's strengths to the program, and greater exposure to the geographic location/city. Conclusion While both in-person and virtual interviews have their own benefits and limitations, virtual interviews appear to be more cost-effective and time-efficient while in-person interviews provide better opportunities to assess program fit and culture. A hybrid format that combines the ideal aspects of both formats may be an optimal solution.

RESUMEN

BACKGROUND: The Cancer Genome Atlas (TCGA) classification of genetic alterations in uveal melanoma is widely used for prognostication. We present novel observations on the impact of TCGA Group specifically for iris melanoma. METHODS: This was a retrospective cohort study at a tertiary referral ocular oncology center. All patients with a diagnosis of iris melanoma who underwent genetic evaluation and assessment for TCGA classification between 20 November 1995 and 5 April 2021 were included. The main outcome measures were visual acuity, secondary glaucoma, tumor recurrence, melanoma-related metastasis and death per TCGA group. RESULTS: There were a total of 78 patients included. The mean patient age was 49.6 years (median 53.0, range 3.0-85.0), mean tumor basal diameter was 6.7 mm (median 6.0, range 1.5-22.0), and mean tumor thickness was 2.6 mm (median 2.5, range 0.5-8.5). Cytology results confirmed iris melanoma (93%) or were inconclusive (7%). The TCGA groups included Group A (n = 36, 46%), Group B (n = 7, 9%), Group C (n = 34, 44%), and Group D (n = 1, 1%). There was no statistically significant difference in outcomes of visual acuity, tumor thickness reduction, secondary glaucoma, tumor recurrence, melanoma-related metastasis or death per individual TCGA group (A vs. B vs. C vs. D) and per bimodal comparison (A/B vs. C/D). CONCLUSIONS: In this analysis, iris melanoma was classified as TCGA group A or B in 55% and as C or D in 45%. The TCGA classification was not predictive of melanoma-related metastasis or death.

RESUMEN

IMPORTANCE: Individuals with perceived experience and expertise are invited by editorial boards to provide commentary through editorials. Female representation among editorialists is not yet defined. OBJECTIVE: To determine female representation as editorial authors in 3 high-impact general ophthalmology journals. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study investigates the proportion of female authorship in editorials published between 2005 to 2009 and 2015 to 2019 in 3 journals: Ophthalmology, JAMA Ophthalmology, and American Journal of Ophthalmology. Data were collected from April to June 2020. MAIN OUTCOMES AND MEASURES: Proportions of female first and senior (last or solo) authors between 2005 to 2009 compared with 2015 to 2019. Secondary outcome measures include representation by sex across degree types and subspecialties. Comparisons were made for all editorialists and ophthalmologist editorialists. RESULTS: Of 814 editorial articles, there were 1179 (first and senior) authors identified. Women held 301 (25.5%) of these authorships, including 116 of 365 first authorships (32.9%) and 185 of 814 senior authorships (23.9%). Overall, female first and senior authorships grew by 68.0% between 2005 to 2009 and 2015 to 2019 (85 of 469 [18.1%] vs 216 of 710 [30.4%]; difference, 12.3%; 95% CI, 7.4-317.2; P < .001). Between 2005 to 2009 and 2015 to 2019, first and senior authorships by women increased (first: 33 of 133 [24.8%] vs 83 of 232 [35.8%]; difference, 11.0%; 95% CI, 1.4-320.6; P = .03; senior: 52 of 336 [15.5%] vs 133 of 478 [27.8%]; difference, 12.3%; 95% CI, 6.8-317.9; P < .001). JAMA Ophthalmology most substantially contributed to the increase in female first and senior authorships (13.8% and 16%), although the test for homogeneity among the 3 journals was not significant. The proportion of female ophthalmologist first authors was greater than the proportion of American Board of Ophthalmology-certified female ophthalmologists (81 of 281 [28.9%] vs 123 of 672 [18.3%]; difference, 10.6%; 95% CI, 5.3-315.9; P < .001). CONCLUSIONS AND RELEVANCE: The proportion of female senior authors increased by 68.0% between 2005 to 2009 and 2015 to 2019, but female authors represented only 25.5% of editorialists. Compared with male ophthalmologists, female ophthalmologists were more commonly first than senior authors. Additionally, female authors were more likely to be nonophthalmologists or to hold nonmedical, non-PhD degrees. While the swelling rank of female editorialists has paralleled the rising proportion of female ophthalmologists over time, parity by sex has yet to be attained. Greater awareness of disparities and strategies to mitigate them may help equalize representation.

RESUMEN

BACKGROUND AND OBJECTIVE: To characterize patient-identified barriers to care in those non-compliant with retina appointments during the coronavirus disease 2019 (COVID-19) pandemic. PATIENTS AND METHODS: Inclusion criteria included non-compliant patients from March 1, 2020 to May 1, 2020. Ultimately, 1,345 patients were invited to complete a 14-question survey. A retrospective chart review correlated clinical and demographic information. Univariate logistic regression, independent-samples t-test, and Pearson correlation coefficient identified differences among subgroups. RESULTS: Of the 1,345 patients, 181 (13.5%) completed the survey. The most significant barriers to care included fear of COVID (76/181; 42.0%), wait times (21/181; 11.6%), and costs (11/181; 6.1%). Patients who got their COVID information from the Centers for Disease Control and Prevention (7.8 ± 2.4) and televised news (8.0 ± 2.0) had higher levels of fear. Finally, patients with diabetic retinopathy and higher Charlson Comorbidity Index scores had greater concerns of COVID (P = .034 and P = .047, respectively). CONCLUSION: This survey study suggests fear of COVID-19 is a prominent new barrier to retinal care. Identifying those at risk for loss to follow-up can guide practices as the pandemic continues.

RESUMEN

Objective This study aimed to evaluate the experiences and preferences of ophthalmology fellowship applicants utilizing a virtual interview format. Design Present study is a cross-sectional study. Subjects All fellowship applicants to Wills Eye Hospital during 2020 to 2021 application cycle were included. Methods A nonvalidated, online survey was conducted, and surveys were distributed at the conclusion of the interview process after rank list submission. Main Outcome Measures Applicant demographics, application submissions, interview experiences, financial considerations, and suggestions for improvement of the virtual interview process were the primary outcomes of this cross-sectional study. Results Survey responses were received from 68 fellowship applicants (34% response rate). Thirty (44%) applicants preferred in-person interviews, 25 (36%) preferred virtual interviews, and 13 (19%) would like to prefer the option to choose either. Fifty-five of 68 (80%) applicants attended the same range of interviews for which they received interview invitations. Reduced costs were reported as the highest ranked strength of virtual interviews in 44 (65%) applicants, with a majority of respondents (68%) spending less than U.S. $250 throughout the entire process. The highest ranked limitation for virtual interviews was limited exposure to the culture/environment of the program in 20 (29%) respondents. On a scale of 0 to 100, the mean (standard deviation [SD]) satisfaction level with the fellowship application process was 74.6 (18.3) and mean (SD) perceived effectiveness levels of virtual interviews was 67.4 (20.4). Conclusion Respondents were generally satisfied with virtual interviews and noted reduced costs and increased ability to attend more fellowship interviews as the strengths of the virtual interview format. Limited exposure to the culture/environment of the program was cited as the most important limitation.

RESUMEN

Cowden syndrome is an autosomal dominant disorder characterized by hamartomas, as well as benign and malignant neoplasms that may present in organ systems throughout the body. It also poses an increased lifetime cancer risk in those with the disorder. Its clinical presentation is often variable, and diagnosis can be challenging. In the head and neck region, it can present as thyroid enlargement or mass formation, cutaneous and mucocutaneous lesions of the skin and the oral cavity. The most typical oral manifestations of Cowden syndrome are oral papillomatosis and a cobblestone appearance of the mucosa. We present a case of vascular malformation of the tongue in a patient with Cowden syndrome. This lesion was similar in appearance to a cutaneous hamartoma on the patient's upper extremity. He had received prior surgical intervention for this tongue mass, and complete resection was recommended subsequently. However, in search of a less invasive treatment to minimize impact on speech and oral function, sclerotherapy was performed, resulting in resolution of the lesion. Sclerotherapy is a well-documented treatment for head and neck vascular malformations, but it is not universally employed. In our patient with atypical oral manifestation of Cowden syndrome, bleomycin sclerotherapy was employed, resulting in resolution of the lesion, as well as preservation of speech articulation and oral function.
