Gender Disparities in Mentorship and Career Outcomes in Ophthalmology.

Background: Gender disparities in the field of ophthalmology have been increasingly recognized. Although mentorship has been proposed as a contributing factor, there are limited data on the differences in mentorship experiences by gender among ophthalmologists. Objective: The purpose of this study was to evaluate gender disparities in mentorship experiences among ophthalmologists, and the impact of mentorship disparities on career outcomes. Design: Prospective, cross-sectional study. Setting: Web-based survey distributed through ophthalmology listservs. Participants: Ophthalmologists and ophthalmologists-in-training who completed the survey. Exposure: Training and practicing in the field of ophthalmology. Main Outcome Measures: Mentorship score based on 10 items from a previously published scale of mentorship quality and self-reported career outcomes (income, job satisfaction, achievement of career goals, and support to achieve future career goals). Results: We received survey responses from 202 male and 245 female ophthalmologists. Female ophthalmologists reported significantly lower mentorship satisfaction and worse quality of mentorship (p < 0.03). Female ophthalmologists also reported significantly lower income, worse job satisfaction, and lower rates of goal achievement and support to achieve future goals; all of these career outcomes, except income level, were partly mediated by mentorship score (mediation effect ranged from 29% to 68%, p < 0.014). Conclusions and Relevance: Gender-based inequities in achievement of career goals and job satisfaction are partly mediated by disparities in mentorship. Therefore, focused mentorship of women in ophthalmology at all career stages is imperative to reduce these inequities.

Artificial Intelligence to Differentiate Pediatric Pseudopapilledema and True Papilledema on Fundus Photographs.

Purpose: To develop and test an artificial intelligence (AI) model to aid in differentiating pediatric pseudopapilledema from true papilledema on fundus photographs. Design: Multicenter retrospective study. Subjects: A total of 851 fundus photographs from 235 children (age < 18 years) with pseudopapilledema and true papilledema. Methods: Four pediatric neuro-ophthalmologists at 4 different institutions contributed fundus photographs of children with confirmed diagnoses of papilledema or pseudopapilledema. An AI model to classify fundus photographs as papilledema or pseudopapilledema was developed using a DenseNet backbone and a tribranch convolutional neural network. We performed 10-fold cross-validation and separately analyzed an external test set. The AI model's performance was compared with 2 masked human expert pediatric neuro-ophthalmologists, who performed the same classification task. Main Outcome Measures: Accuracy, sensitivity, and specificity of the AI model compared with human experts. Results: The area under receiver operating curve of the AI model was 0.77 for the cross-validation set and 0.81 for the external test set. The accuracy of the AI model was 70.0% for the cross-validation set and 73.9% for the external test set. The sensitivity of the AI model was 73.4% for the cross-validation set and 90.4% for the external test set. The AI model's accuracy was significantly higher than human experts on the cross validation set (P < 0.002), and the model's sensitivity was significantly higher on the external test set (P = 0.0002). The specificity of the AI model and human experts was similar (56.4%-67.3%). Moreover, the AI model was significantly more sensitive at detecting mild papilledema than human experts, whereas AI and humans performed similarly on photographs of moderate-to-severe papilledema. On review of the external test set, only 1 child (with nearly resolved pseudotumor cerebri) had both eyes with papilledema incorrectly classified as pseudopapilledema. Conclusions: When classifying fundus photographs of pediatric papilledema and pseudopapilledema, our AI model achieved > 90% sensitivity at detecting papilledema, superior to human experts. Due to the high sensitivity and low false negative rate, AI may be useful to triage children with suspected papilledema requiring work-up to evaluate for serious underlying neurologic conditions.

The relationship of shift work disorder with symptoms of depression, anxiety, and stress.

Shift workers commonly suffer from disturbed sleep, which is known to affect mental health in other populations. Shift work disorder (SWD) is characterized by complaints of insomnia and/or excessive daytime sleepiness temporally associated with working non-standard schedules that occur during the usual time for sleep. Few studies have explored the extent to which workers with vs. without SWD experience worse mental health. We administered the Shift Work Disorder Screening Questionnaire to 60 adults engaged in various shift work schedules to categorize workers as being at high or low risk for SWD. Mental health outcomes were measured using the Depression Anxiety Stress Scale-21 (DASS-21). Linear regression was performed for each DASS-21 subscale, adjusting for age, sex, shift type, sleep duration, and frequency of alcohol use. Most participants (55 %) were at high risk for SWD. High-risk participants had higher depressive symptoms than low-risk participants, B = 3.59, 95 % CI [0.54, 6.65], p = .02. The estimated value for those at high risk for SWD corresponded to clinically significant mild depressive symptoms, (M = 13.43), compared to those at low risk, (M = 9.84). High risk for SWD was marginally associated with increased stress symptoms, B = 2.48, 95 % CI [-0.06,5.02], p = .06. Our findings add to the body of evidence that SWD is associated with poor mental health outcomes. Providing interventions specific to the sleep impacts of SWD, including tailored cognitive behavioral therapy for insomnia, may improve shift workers' mental health.

Comparison of Eye Tracking and Teller Acuity Cards for Visual Acuity Assessment in Pediatric Cortical/Cerebral Visual Impairment.

PURPOSE: To compare eye tracking and Teller acuity cards (TAC) for assessment of visual acuity in children with cortical, or cerebral, visual impairment (CVI). DESIGN: Reliability and validity study. METHODS: We recruited 41 children with CVI from a single academic pediatric neuro-ophthalmology clinic. All children performed eye tracking to measure visual acuity, and 26 children completed TAC assessment by a masked examiner. Additionally, 2 pediatric neuro-ophthalmologists graded visual behavior using the 6-level Visual Behavior Scale (VBS). Eye tracking and TAC were performed at baseline and at 1 month. Test-retest reliability of eye tracking and TAC were assessed using the intraclass correlation coefficient (ICC). Eye tracking and TAC visual acuities were correlated with one another and VBS scores using the Spearman correlation coefficient. RESULTS: Test-retest reliability was excellent for eye tracking measurement of visual acuity (ICC = 0.81, P < .0001). For pediatric CVI, TAC test-retest reliability was fair (ICC = 0.42, P = .04). There was a moderate correlation between eye tracking and TAC (r = 0.43, P = .03) and between TAC and VBS score (r = 0.50, P = .009), and a strong correlation between eye tracking grating acuity and VBS score (r = 0.72, P < .0001). CONCLUSIONS: In our cohort of children with CVI, grating acuity measured by eye tracking demonstrated higher test-retest reliability and stronger correlation with pediatric neuro-ophthalmologic assessment of visual behavior than Teller acuity. Objective determination of gaze direction by an eye tracking camera may be more accurate than human assessment in this population. Future research is needed to determine the optimal methods of longitudinal assessment of visual function and functional vision in children with CVI.

Supracerebellar infratentorial resection of a torcular lesion causing fulminant intracranial hypertension: illustrative case.

BACKGROUND: Venous sinus stenosis has been implicated in intracranial hypertension and can lead to papilledema and blindness. The authors report the unique case of a cerebellar transtentorial lesion resulting in venous sinus stenosis in the torcula and bilateral transverse sinuses that underwent resection. OBSERVATIONS: A 5-year-old male presented with subacute vision loss and bilateral papilledema. Imaging demonstrated a lesion causing mass effect on the torcula/transverse sinuses and findings of increased intracranial pressure (ICP). A lumbar puncture confirmed elevated pressure, and the patient underwent bilateral optic nerve sheath fenestration. Cerebral angiography and venous manometry showed elevated venous sinus pressures suggestive of venous hypertension. The patient underwent a craniotomy and supracerebellar/infratentorial approach. A stalk emanating from the cerebellum through the tentorium was identified and divided. Postoperative magnetic resonance imaging showed decreased lesion size and improved sinus patency. Papilledema resolved and other findings of elevated ICP improved. Pathology was consistent with atrophic cerebellar cortex. Serial imaging over 6 months demonstrated progressive decrease in the lesion with concurrent improvements in sinus patency. LESSONS: Although uncommon, symptoms of intracranial hypertension in patients with venous sinus lesions should prompt additional workup ranging from dedicated venous imaging to assessments of ICP and venous manometry.

A Multifaceted Implementation Strategy to Increase Out-of-Office Blood Pressure Monitoring: The EMBRACE Cluster Randomized Clinical Trial.

Importance: Few primary care patients complete guideline-recommended out-of-office blood pressure (BP) monitoring prior to having hypertension diagnosed. Objective: To evaluate the effectiveness of a behavioral theory-informed, multifaceted implementation strategy on out-of-office BP monitoring (ambulatory BP monitoring [ABPM] or home BP monitoring [HBPM]) among patients with new hypertension. Design, Setting, and Participants: This 2-group, pre-post cluster randomized trial was conducted within a primary care network of 8 practices (4 intervention practices with 99 clinicians; 4 control practices with 55 clinicians) and 1186 patients (857 intervention; 329 control) with at least 1 visit with elevated office BP and no prior hypertension diagnosis between October 2016 and September 2017 (preimplementation period) or between April 2018 and March 2019 (postimplementation period). Data were analyzed from February to July 2023. Interventions: Usual care (control group) or a multifaceted implementation strategy consisting of an accessible ABPM service; electronic health record (EHR) tools to facilitate test ordering; clinician education, reminders, and feedback relevant to out-of-office BP monitoring; nurse training on HBPM; and patient information handouts. Main Outcomes and Measures: The primary outcome was patient completion of out-of-office BP monitoring within 6 months of an eligible visit. Secondary outcomes included clinician ordering of out-of-office BP monitoring. Blinded assessors extracted outcomes from the EHR. Results: A total of 1186 patients (857 intervention; 329 control) were included, with a mean (SD) age of 54 (16) years; 808 (68%) were female, and 549 (48%) were Spanish speaking; among those with race and ethnicity documented, 123 (10%) were Black or African American, and 368 (31%) were Hispanic. Among intervention practices, the percentage of visits resulting in completed out-of-office BP monitoring increased from 0.6% (0% ABPM; 0.6% HBPM) to 5.7% (3.7% ABPM; 2.0% HBPM) between the preimplementation and postimplementation periods (P = .009). Among control practices, the percentage of visits resulting in completed out-of-office BP monitoring changed from 5.4% (0% ABPM; 5.4% HBPM) to 4.3% (0% ABPM; 4.3% HBPM) during the corresponding period (P = .94). The ratio of relative risks (RRs) of out-of-office BP monitoring in the postimplementation vs preimplementation periods for intervention vs control practices was 10.5 (95% CI, 1.9-58.0; P = .01). The ratio of RRs of out-of-office BP monitoring being ordered was 2.2 (95% CI, 0.8-6.3; P = .12). Conclusions and Relevance: This study found that a theory-informed implementation strategy that included access to ABPM modestly increased out-of-office BP monitoring among patients with elevated office BP but no hypertension diagnosis. Trial Registration: ClinicalTrials.gov Identifier: NCT03480217.

Genetic testing for infantile nystagmus syndrome with or without associated findings.

PURPOSE: To review the published literature assessing the clinical utility of genetic testing in individuals with infantile nystagmus syndrome (INS), defined as binocular conjugate nystagmus and onset prior to 6 months of age, with or without associated findings. METHODS: A literature search was last conducted in October 2022. The results were limited to articles published in English. The search yielded 517 abstracts, of which 72 papers were reviewed in full text. Of these papers, 4 met the criteria for inclusion and were graded by a study methodologist. RESULTS: The 4 studies that met inclusion criteria used next-generation sequencing with gene panels ranging from 31 to 336 genes. The overall molecular diagnostic rate ranged from 35% to 60% in the included studies, although the yield was higher when genetic testing was guided by clinical phenotyping (approximately 80%) and in the subsets of patients with a family history (up to 88%). As many as 30% of patients tested had a reclassification of the diagnosis based on the genetic testing results. CONCLUSIONS: Genetic testing has the potential to provide a definitive diagnosis and identify treatable conditions in patients presenting with INS, especially when considered in conjunction with clinical phenotyping and family history.

Levodopa/Carbidopa to Augment the Treatment of Amblyopia: A Report by the American Academy of Ophthalmology.

PURPOSE: To review the published literature on the use of levodopa/carbidopa to augment the treatment of amblyopia. METHODS: Literature searches for English language studies were last conducted in October 2022 in the PubMed database with no date restrictions. The combined searches yielded 55 articles, of which 23 were reviewed in full text. Twelve of these were considered appropriate for inclusion in this assessment and were assigned a level of evidence rating by the panel methodologist. Nine studies were rated level I, and 3 studies were rated level II; there were no level III studies. RESULTS: The duration of treatment was limited to 3 to 16 weeks because of concern about long-term adverse effects such as tardive dyskinesia. This complication was not reported in any of the study participants. The dose of levodopa ranged from 1.5 to 8.3 mg/kg/day, generally divided into 3 daily doses. The carbidopa dose was approximately 25% of the levodopa dose in all treatments. Evidence from these studies indicates that augmenting traditional patch occlusion therapy with the oral administration of levodopa/carbidopa can improve the vision of amblyopic children, but the effect was small (0.17-0.3 logarithm of the minimum angle of resolution [logMAR] units) and only statistically significant when compared with patching alone in 2 of the 12 studies cited. Regression of vision was reported in the majority of studies (9 of 12 reported; range, 0-0.17 logMAR unit regression) after discontinuation of therapy. Short-term side effects of the medications were not consistently reported but were most frequently mild and included headache and nausea. CONCLUSIONS: The best available evidence is currently insufficient to show that augmenting amblyopia therapy using up to 16 weeks of levodopa/carbidopa will result in meaningful improvement in visual acuity. Given the potential for significant side effects such as tardive dyskinesia with long-term therapy, levodopa/carbidopa does not appear to be a viable option for amblyopia therapy FINANCIAL DISCLOSURE(S): The author(s) have no proprietary or commercial interest in any materials discussed in this article.

The Nictavi Tarsus Patch: A New Device for Achieving Temporary Eyelid Closure in Lagophthalmos.

Purpose: To evaluate the effectiveness, tolerability, and safety of the Nictavi Tarsus Patch™ (NTP) in inducing temporary eyelid closure for the management of lagophthalmos in the pediatric and young adult population. Methods: We prospectively enrolled 20 patients <21 years of age who had previously been managed for lagophthalmos to trial the NTP in clinic. Inter-palpebral fissure distance (IPFD) was compared before and after the placement of the NTP in the eyes-closed position using paired t-tests. Subjects then underwent a 3-night home trial with the NTP, and parent and subject perceptions of effectiveness, comfort, and complications with the patch were analyzed using Likert scale survey questions. Results: Twenty subjects ages 2-20 years with paralytic (65%) and non-paralytic (35%) lagophthalmos were enrolled. The NTP improved lagophthalmos from a mean pre-placement IPFD of 3.3 mm to post-placement IPFD of 0.4 mm (p < 0.01). Overall, 80% of subjects achieved successful eyelid closure defined as ≤1 mm of post-placement IPFD. When stratified by subtype, 100% of subjects with paralytic lagophthalmos achieved successful eyelid closure compared to 71% of subjects with non-paralytic lagophthalmos. On a scale of 1 (worst) to 5 (best), parents rated the NTP at 4.3±0.7 for comfort while wearing, 4.3±1.0 for comfort in removing, 4.6±0.7 for ease of use, and 4.3±0.9 for effectiveness. Ninety-three percent of parents reported preferring NTP to other eyelid closure methods previously tried and indicated that they would use it again. Conclusion: The NTP is an effective, tolerable, and safe method of eyelid closure for children and young adults.

Age-dependent associations of human milk oligosaccharides with body size and composition up to 4 years of age.

BACKGROUND: Human milk oligosaccharides (HMOs) are major components of human milk that may mediate its beneficial effects on infant growth. OBJECTIVES: To investigate relationships between HMO concentrations in milk at 6 wk postpartum and anthropometry to 4 y of age in human milk-fed infants. METHODS: Milk samples were collected from 292 mothers at 6 wk (median 6.0 wk; range 3.3, 11.1] postpartum in a longitudinal, population-derived cohort. Of the infants, 171 were exclusively human milk-fed to 3 mo of age and 127 to 6 mo. Concentrations of 19 HMOs were quantified using high-performance liquid chromatography. Maternal secretor status (n = 221 secretors) was determined from 2'-fucosyllactose (2'FL) concentration. We calculated z-scores for child weight, length, head circumference, summed triceps and subscapular skinfold thicknesses, and weight-for-length at 6 wk, 6 mo, 12 mo, and 4 y. We investigated associations of secretor status and each HMO measure with change from birth for each z-score using linear mixed-effects models. RESULTS: Maternal secretor status was not associated with anthropometric z-scores up to 4 y of age. Several HMOs were associated with z-scores at 6 wk and 6 mo, predominantly within secretor status subgroups. Higher levels of 2'FL were associated with greater weight [ß = 0.91 increase in z-score per SD increase log-2'FL, 95% CI (0.17, 1.65)] and length [ß = 1.22, (0.25, 2.20)] in children born to secretor mothers, but not body composition measures. Higher lacto-N-tetraose was associated with greater weight [ß = 0.22, (0.02, 0.41)] and length (ß = 0.30, (0.07, 0.53)] among children born to nonsecretor mothers. Several HMOs were associated with anthropometric measures at 12 mo and 4 y of age. CONCLUSIONS: Milk HMO composition at 6 wk postpartum is associated with several anthropometry measures up to 6 mo of age in a potential secretor status-specific manner, with largely different HMOs associating with anthropometry from 12 mo to 4 y of age.

Surgical Treatments to Improve Visual Acuity in Infantile Nystagmus Syndrome: A Report by the American Academy of Ophthalmology.

PURPOSE: To review the literature on the efficacy of surgical procedures to improve visual acuity (VA) in patients with infantile nystagmus syndrome (INS). METHODS: Literature searches were last conducted in January 2022 in the PubMed database for English-language studies with no date restrictions. The combined searches yielded 354 abstracts, of which 46 were reviewed in full text. Twenty-three of these were considered appropriate for inclusion in this assessment and were assigned a level of evidence rating by the panel methodologist. RESULTS: One included study was a randomized trial; the remaining 22 were case series. The 23 studies included children and adults with INS and a variable proportion with anomalous head position (AHP), strabismus, and sensory diagnoses. The surgical interventions evaluated included large recessions, tenotomy and reattachment (TAR), myectomy with or without pulley fixation, and anterior extirpation of the 4 horizontal rectus muscles, as well as various procedures to correct an AHP in which VA was reported as a secondary outcome. The data were mixed, with improvements in binocular best-corrected visual acuity (BCVA) ranging from no improvement to 0.3 logarithm of the minimum angle of resolution (logMAR), or 3 lines. (Most studies were in the range of 0.05-0.2 logMAR.) Statistically significant improvement in VA was noted in 12 of 16 studies (75%) that performed statistical analyses, with no clear advantage of any single procedure. Complications and reoperations were lowest in patients who underwent TAR and highest in those who underwent myectomy or anterior extirpation. CONCLUSIONS: The best available evidence suggests that eye muscle surgery in patients with INS results in a modest improvement in VA.

Evaluation of Streamed Hardware-to-Software Telemedicine Strabismus Consultations Utilizing Video Glasses.

Background: While video glasses have been shown to be an effective tool for real-time pediatric strabismus telemedicine consultations, the high cost of the hardware-to-hardware conferencing system and bandwidth limitations may present barriers to accessibility and widespread adoption. This study evaluates the use of video glasses with a more affordable hardware-to-software video conferencing system for real-time strabismus consultations across multiple graders. Methods: A pediatric ophthalmologist (Grader 1) wearing video glasses simultaneously performed and recorded strabismus examinations in primary gaze, with and without correction, both at distance and near. Recorded parameters included strabismus category, angle measurements, and ocular motility. Three years later, four pediatric ophthalmologists (Graders 1-4) reviewed and graded streamed video feed transmitted at 1 megabit per second (Mbps) from a hard-wired codec to software. Agreement between streamed and gold standard in-person findings was determined by weighted kappa (κ) for categorical variables, intraclass correlation coefficient (ICC) for continuous variables, and percent agreement. Results: Eighteen patients aged 4-11 years (median, 7 years) were included. Agreement in strabismus category between in-person and streamed examinations was perfect for both horizontal and vertical deviations (κ=1.0). Almost perfect agreement was found for degree manifest (tropia vs intermittent tropia vs phoria) across graders (κ=0.91, range 0.86-0.97). Agreement for angle measurements was excellent across graders (ICC = 0.97, range 0.97-0.98). Extraocular motility agreement was 90% for all graders combined, with Grader 1 having 100% agreement between her in-person and streamed examinations. Conclusion: Feed obtained from video glasses streamed through a hardware-to-software video conferencing system at 1 Mbps is a reliable tool for pediatric strabismus telemedicine evaluations.

Effectiveness of Laser Refractive Surgery to Address Anisometropic Amblyogenic Refractive Error in Children: A Report by the American Academy of Ophthalmology.

PURPOSE: To review the published literature assessing the safety and effectiveness of laser refractive surgery to treat anisometropic amblyogenic refractive error in children aged ≤ 18 years. METHODS: A literature search of the PubMed database was conducted in October 2021 with no date limitations and restricted to publications in English. The search yielded 137 articles, 69 of which were reviewed in full text. Eleven articles met the criteria for inclusion and were assigned a level of evidence rating. RESULTS: The 11 included articles were all level III evidence and consisted of 1 case-control study and 10 case series. Six studies used laser-assisted in situ keratomileusis (LASIK), 1 used photorefractive keratectomy (PRK), 1 used refractive lenticule extraction/small incision lenticule extraction, and the rest used a combination of LASIK, PRK, laser epithelial keratomileusis (LASEK), or refractive lenticule extraction/small incision lenticule extraction. Five studies enrolled patients with anisometropic myopia, 2 studies enrolled patients with anisometropic hyperopia, and the remainder were mixed. Although all studies demonstrated an improvement in best-corrected visual acuity (BCVA), the magnitude of improvement varied widely. As study parameters varied, a successful outcome was defined as residual refractive error of 1 diopter (D) or less of the target refraction because this was the most commonly used metric. Successful outcomes ranged between 38% and 87%, with a mean follow-up ranging from 4 months to 7 years. Despite this wide range, all studies demonstrated an improvement in the magnitude of anisometropia. Regression in refractive error occurred more frequently and to a greater degree in myopic eyes and eyes with longer follow-up, and in younger patients. Although one study reported 2 free flaps, most studies reported no serious adverse events. The most common complications were corneal haze and striae. CONCLUSIONS: Findings from included studies suggest that laser refractive surgery may address amblyogenic refractive error in children and that it appears to decrease anisometropia. However, the evidence for improvement in amblyopia is unclear and long-term safety data are lacking. Long-term data and well-designed clinical studies that use newer refractive technologies in standardized patient populations would help address the role of refractive surgery in children and its potential impact on amblyopia.

Maternal Diet Is Associated with Human Milk Oligosaccharide Profile.

SCOPE: Human milk oligosaccharides (HMOs) are complex glycans that are abundant in human milk. The potential impact of a maternal diet on individual HMOs and the association with secretor status is unknown. Thus, this study is aimed to examine the association between maternal diet and HMO profiles. METHODS AND RESULTS: This is a cross-sectional study of the MAMI cohort with 101 human milk samples from healthy mothers. HMO profiling is assessed by quantitative HPLC. Maternal dietary information is recorded through an FFQ, and perinatal factors including the mode of delivery, antibiotic exposure, and breastfeeding practices, are collected. A more significant effect of diet on HMO profiles is observed in secretor mothers than in non-secretor mothers. (Poly)phenols and fibers, both soluble and insoluble, and several insoluble polysaccharides, pectin, and MUFA are associated with the secretor HMO profiles. CONCLUSIONS: Maternal diet is associated with the composition and diversity of HMO in a secretor status-dependent manner. The relationship between maternal diet and bioactive compounds, including HMOs, which are present in human milk, needs further research due its potential impact on infant development and health outcomes.
