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.

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.

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.

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.

Neovascularization of the optic disc and peripheral retinal ischemia in a child with a novel variant in ALMS1 (Alström syndrome).

Purpose: The ophthalmologic findings in Alström syndrome include cone-rod dystrophy, optic atrophy, optic disc drusen, and retinal telangiectasias with exudative retinopathy. Here we describe peripheral retinal non-perfusion with neovascularization of the disc (NVD) in a child with Alström syndrome-related cone-rod dystrophy. Observations: A six-year-old girl with a diagnosis of Alström syndrome based on a homozygous nonsense likely pathogenic variant in ALMS1 (NM_015120.4:c.4746C > G; p.Tyr1582Ter) was seen in the ophthalmology clinic for nystagmus, photophobia, and poor vision with non-recordable scotopic and photopic electroretinography (ERG) responses. On routine follow-up exam, she was found to have optic disc hyperermia and apparent swelling. Brain and orbital magnetic resonance imaging (MRI) and lumbar puncture with opening pressure measurement were unremarkable. Because the optic disc findings were persistent, she underwent examination under anesthesia with fluorescein angiography, which revealed bilateral neovascularization of the optic disc (NVD) with peripheral retinal non-perfusion. Systemic workup including hemoglobin A1C measurement was normal. She underwent four sessions of bilateral panretinal photocoagulation and three intravitreal injections of anti-vascular endothelial growth factor (VEGF) with subsequent improvement of the NVD in both eyes. Conclusions and importance: Neovascularization of the optic disc may arise in Alström syndrome as a sequela of peripheral retinal ischemia. This finding may be partially responsive to panretinal photocoagulation and intravitreal anti-VEGF therapy.

Characteristics and Outcomes of Idiopathic and Non-idiopathic Ocular Motor Apraxia in Children.

PURPOSE: To systematically compare idiopathic and non-idiopathic ocular motor apraxia (OMA) in children. METHODS: A retrospective chart review was conducted of all children (< 18 years) diagnosed as having OMA from 2010 to 2020. Demographics, clinical characteristics, and oculomotor outcomes were compared for children with idiopathic and non-idiopathic OMA. RESULTS: Thirty-seven children were included, 17 (46%) with idiopathic OMA and 20 (54%) with non-idiopathic OMA. Among patients with non-idiopathic OMA, Joubert syndrome was the most frequent underlying diagnosis (30%). Strabismus (45% vs 12%, P = .04), nystagmus (30% vs 0%, P = .02), and vertical saccade involvement (25% vs 0%, P = .049) were significantly more common in non-idiopathic than idiopathic OMA, respectively. Neuroimaging abnormalities (90% vs 18%, P < .0001) and developmental delays (100% vs 59%, P = .002) were also more frequent in non-idiopathic than idiopathic OMA, respectively. Endocrine disorders (most commonly growth hormone deficiency) were diagnosed in 12% and 20% of children with idiopathic and non-idiopathic OMA, respectively (P = .67). On survival curve analysis, improvement in OMA occurred faster and more frequently in children with idiopathic than non-idiopathic OMA (median time to improvement 56 vs 139 months, respectively, P = .034). CONCLUSIONS: Non-idiopathic OMA is associated with a higher rate of vertical saccade involvement, nystagmus, and developmental delays. These findings should prompt neuroimaging in children with OMA. Additionally, endocrine disorders may be more frequent in children with OMA than the general pediatric population. [J Pediatr Ophthalmol Strabismus. 2022;59(5):326-331.].

Etiology and Outcomes of Acquired Pediatric Sixth Nerve Palsies.

BACKGROUND: Acquired sixth nerve (CN6) palsies in children may be benign or associated with an underlying neurologic condition. In children who presented with isolated (no associated neurologic or ophthalmic symptoms or signs) CN6 palsies, the rate of newly diagnosed neurologic disorders (such as tumors) is unclear. Moreover, the factors associated with spontaneous resolution and amblyopia in children with acquired CN6 palsies are unknown. METHODS: We retrospectively reviewed the charts of all children younger than 18 years diagnosed with CN6 palsy at our institution from 2010 to 2020. We recorded ophthalmologic and neurologic history and examination findings, neuroimaging results, etiology of CN6 palsy, and outcomes including spontaneous resolution and amblyopia. We assessed etiologies of isolated and nonisolated CN6 palsies as well as frequency and factors associated with spontaneous resolution and amblyopia (in children ≤7 years). RESULTS: One hundred seventy-two children met inclusion criteria. Twenty CN6 palsies (12%) were isolated at presentation. Most isolated cases were presumed postviral or postvaccination (50%) or idiopathic (30%), but 2 cases (10%) were associated with newly diagnosed tumors. Spontaneous resolution occurred in 59% of CN6 palsies at a median of 12.3 weeks and was associated with older age (P = 0.03) and nontumor etiology (P = 0.006). Amblyopia developed in 18% of children at risk, exclusively in those with anisometropia, pre-existing strabismus, or younger than 12 months. CONCLUSIONS: Our findings and chart reviews suggest that approximately 10% of isolated acquired pediatric CN6 palsies are associated with a newly diagnosed brain tumor. This risk must be discussed with parents when considering immediate vs delayed neuroimaging. In addition, infants and children ≤7 years with secondary amblyogenic risk factors (anisometropia or pre-existing strabismus) require close follow-up to monitor and treat amblyopia.

Prospective Cross-Sectional Study of Repeatability of Peripapillary Capillary Density Measurement Using Optical Coherence Tomography Angiography in Eyes With Optic Nerve and Retinal Vascular Pathology.

BACKGROUND: Optical coherence tomography angiography (OCTA) is a new noninvasive imaging modality that provides high resolution images of the optic nerve head and peripapillary retinal capillary vasculature which can be affected by optic nerve or retinal pathologies. High repeatability of peripapillary capillary density measurement using OCTA has been demonstrated in normal eyes and eyes with glaucoma. The purpose of our study was to quantify the repeatability of peripapillary capillary density measurement using OCTA in both normal eyes and eyes with optic atrophy, optic disc edema, and retinal vasculopathy. METHODS: This prospective cross-sectional study enrolled 31 patients (59 eyes) including 16 eyes with optic nerve pathology (7 with disc edema from papilledema and 9 with optic atrophy), 35 eyes with retinal vascular disease, and 8 normal eyes. All eyes were imaged twice (30 minutes apart) with the Optovue AngioVue OCTA instrument to obtain 4.5 × 4.5 mm peripapillary scans. Scans were considered good quality if signal strength was 6 or greater. The OCTA parameters obtained include the radial peripapillary capillary (RPC) density of the whole disc, inside the disc, peripapillary region, and the 4 quadrants of the disc (superior, nasal, inferior, and temporal). A Student's t test was used to compare means. Intraclass correlation coefficient (ICC) was calculated to measure repeatability. RESULTS: Repeatability of RPC density measurements for all regions analyzed demonstrated good to excellent repeatability for the whole cohort {ICC for the whole image was 0.915 (95% confidence interval [CI] = 0.855-0.951)}; ICC for the peripapillary region was 0.945 (95% CI = 0.905-0.969). In the subset of eyes with good image quality (i.e., signal strength ≥ 6), ICC was slightly higher for all regions, with excellent repeatability of the peripapillary region (ICC was 0.971 [95% CI = 0.943-0.986]). Conversely, for eyes with poor image quality scans (i.e., signal strength < 6), ICC was lower, corresponding to moderate to good repeatability for most parameters. For the subset of eyes with optic atrophy, disc edema from papilledema or retinal vasculopathy, all had good to excellent repeatability of the vessel density of the entire disc (ICC values were 0.954 [95% CI = 0.804-0.990], 0.921 [95% CI = 0.711-0.982], and 0.895 [95% CI = 0.788-0.951, respectively]) and of the peripapillary region (ICC values were 0.980 [95% CI = 0.904-0.996], 0.966 [95% CI = 0.854-0.993], and 0.916 [95% CI = 0.827-0.961], respectively). CONCLUSIONS: The peripapillary capillary density measurement obtained using a commercial OCTA instrument is highly repeatable in eyes with optic nerve atrophy, disc edema from papilledema, or retinal vasculopathy.

Adjustable Sutures in the Treatment of Strabismus: A Report by the American Academy of Ophthalmology.

PURPOSE: To review the scientific literature that evaluates the effectiveness of adjustable sutures in the management of strabismus for adult and pediatric patients. METHODS: Literature searches were performed in the PubMed database through April 2021 with no date limitations and were restricted to publications in English. The searches identified 551 relevant citations, of which 55 were reviewed in full text. Of these, 17 articles met the inclusion criteria and were assigned a level of evidence rating by the panel methodologist. The search included all randomized controlled studies regardless of study size and cohort studies of 100 or more patients comparing the adjustable versus nonadjustable suture technique, with a focus on motor alignment outcomes or reoperation rates. RESULTS: The literature search yielded no level I studies. Of the 17 articles that met the inclusion criteria, 11 were rated level II and 6 were rated level III. Among the 12 studies that focused on motor alignment outcomes, 4 small randomized clinical trials (RCTs) did not find a statistically significant difference between groups, although they were powered to detect only very large differences. Seven of 8 nonrandomized studies found a statistically significant difference in motor alignment success in favor of the adjustable suture technique, both overall and in certain subgroups of patients. Successful motor alignment was seen in both exotropia (in 3 studies that were not limited to children) and esotropia (in 1 study of adults and 2 of children). The majority of included studies that reported on reoperation rates found the rates to be lower in patients who underwent strabismus surgery with adjustable sutures, but this finding was not uniformly demonstrated. CONCLUSIONS: Although there are no level I studies evaluating the effectiveness of adjustable sutures for strabismus surgery, the majority of nonrandomized studies that met the inclusion criteria for this assessment reported an advantage of the adjustable suture technique over the nonadjustable technique with respect to motor alignment outcomes. This finding was not uniformly demonstrated among all studies reviewed and warrants further investigation in the development and analysis of adjustable suture techniques.

Increase in Pediatric Pseudotumor Cerebri Syndrome Emergency Department Visits, Inpatient Admissions, and Surgeries During the COVID-19 Pandemic.

BACKGROUND: Pediatric pseudotumor cerebri syndrome (PTCS) is a vision-threatening condition that is associated with female sex and obesity in pubertal and postpubertal children. It is unknown whether the increase in childhood obesity during the COVID-19 pandemic has affected the rates and characteristics of pediatric PTCS. METHODS: We conducted a retrospective study of children evaluated for PTCS (inpatient or emergency department) at our children's hospital before (March 19, 2015 to March 19, 2020) and during (March 20, 2020 to February 20, 2021) the pandemic. We compared the monthly number of inpatient and emergency department encounters for pediatric PTCS before and during the pandemic. In addition, anthropometric and ophthalmologic characteristics of children evaluated for pediatric PTCS before and during the pandemic were compared. RESULTS: A total of 36 encounters in the 5 years before the pandemic and 26 encounters in the 11 months during the pandemic were identified. The median monthly number of encounters for pediatric PTCS was significantly higher during the pandemic compared with the 5 years before the pandemic (2 vs 0, P = 0.0021). Compared with prepandemic patients, children evaluated during the pandemic were older (median age 16 vs 14 years, P = 0.02), with higher rates of obesity (85% vs 66%, P = 0.05) and lower likelihood of reporting Caucasian race (4% vs 31%, P = 0.02). Pandemic patients had worse presenting visual acuity (median logMAR 0.14 vs 0.05, P = 0.05) and were more likely to have fulminant presentation (23% vs 6%, P = 0.04) and require surgical intervention (23% vs 6%, P = 0.04). CONCLUSIONS: At our children's hospital, the rate of inpatient admissions and emergency department visits for pediatric PTCS increased during the pandemic. The severity of disease and frequency of surgical treatment also increased. Racial and ethnic minorities seem to be disproportionately affected. These changes may be related to increasing rates of childhood obesity during the pandemic.
