Abstract
Introduction In 2020, teprotumumab became the first FDA-approved treatment for thyroid eye disease (TED). In clinical trials, hyperglycemia had been described as mild and controlled with medication. We present a case that occurred in 2020 of a 67-year-old male with TED and pre-existing glucose intolerance, who was hospitalized with severe hyperglycemia (1,059 mg/dL) after three doses of teprotumumab. Case Presentation This patient's HbA1c was in the pre-diabetic range (6.3%) 6 months prior to initiating teprotumumab. After three doses, the patient was hospitalized with hyperosmolar hyperglycemic nonketotic syndrome and an HbA1c of 11.7%. He was diagnosed with type 2 diabetes mellitus and treated with insulin aspart mixed 70/30. He remained on this regimen for 14 months with an A1c of 6.0%. He then self-discontinued the insulin, with an A1c 4 months later measuring 5.5%. The patient's latest HbA1c approximately two and a half years after hospitalization was 6.1% on no medications. Conclusion It appears that teprotumumab was a trigger for this transient case of diabetes, and detecting those that have underlying glucose intolerance ahead of time is important. We recommend blood glucose levels for patients with pre-diabetes prior to and ideally in the first few days after each infusion, to help determine patients at a greater risk for adverse hyperglycemic outcomes. A glucometer may be valuable for patients to self-monitor while on teprotumumab. If fasting blood glucose is ≥126 mg/dL or non-fasting glucose is >200 mg/dL, patients should be referred for further diabetes assessment and possible treatment initiation.

Abstract
PURPOSE Using optical coherence tomography angiography (OCTA), this study compared intrasession repeatability versus intersession reproducibility of macular vessel parameters in glaucoma and non-glaucoma subjects. METHODS 6x6 mm2 macular OCTA scans (Cirrus HD-OCT 5000) were acquired from glaucomatous and non-glaucomatous subjects as part of an observational, longitudinal study. Vessel area density (VAD) and vessel skeleton density (VSD) were calculated using research-based quantification software while perfusion density (PDZ) and vessel density (VDZ) were calculated using commercially developed software (Cirrus 11.0, Carl Zeiss Meditec). Intrasession repeatability and intersession reproducibility were determined using within-eye standard deviation (SW), within-eye coefficient of repeatability (CRW), within-eye coefficient of variation (CVW), and intraclass correlation coefficients (ICC). RESULTS The intrasession repeatability and intersession reproducibility for macular OCTA parameters were similar to one another for both non-glaucomatous and glaucomatous eyes. Intrasession CVW from the non-glaucoma group (n = 73) was 1.097% for VAD, 1.007% for VSD, 2.980% for PDZ, and 2.714% for VDZ. Intersession CVW from the non-glaucoma group (n = 55) was 1.389% for VAD, 1.279% for VSD, 2.935% for PDZ, and 2.695% for VDZ. Intrasession CVW from the glaucoma group (n = 59) was 1.189% for VAD, 0.970% for VSD, 3.827% for PDZ, and 3.542% for VDZ. Intersession CVW from the glaucoma group (n = 45) was 1.412% for VAD, 1.132% for VSD, 3.915% for PDZ, and 3.654% for VDZ. Non-glaucomatous intrasession ICC ranged from 0.711 to 0.824, non-glaucomatous intersession ICC ranged from 0.649 to 0.762, glaucomatous intrasession ICC ranged from 0.710 to 0.853, and glaucomatous intersession ICC ranged from 0.661 to 0.827. CONCLUSIONS Macular OCTA scans can be a useful tool in monitoring the longitudinal progression of glaucoma due to its high repeatability and reproducibility.

Abstract
Purpose The purpose of this study was to investigate how axial length (AL) changes the relationship of intraocular pressure (IOP) with peripapillary vessel density (pVD) in glaucoma versus non-glaucomatous eyes. Methods A population-based, cross-sectional study of 2127 African Americans aged 40 years and older in Inglewood, California, were imaged with 6 × 6-mm optic disc optical coherence tomography angiography scans. There were 1028 healthy subjects (1539 eyes) and 65 subjects with glaucoma (86 eyes) who met inclusion criteria. A multivariable linear mixed effects regression model investigated the relationship of IOP on pVD after controlling for signal strength, retinal nerve fiber layer thickness, and age. These results were stratified by AL groups. Results Higher IOP was a significant predictor of lower pVD among subjects with glaucoma (P = 0.009), but not among healthy subjects (P = 0.26). After stratifying by the sample median AL (23.46 mm), higher IOP was associated with lower pVD among subjects with glaucoma with longer AL (≥ 23.46 mm, P = 0.005), but not among those in the shorter AL (< 23.46 mm, P = 0.45). IOP was not significantly associated with pVD among healthy subjects in either AL stratum. Conclusions Among subjects with glaucoma with longer AL, IOP was significantly associated with pVD. This relationship was not seen among subjects with glaucoma with shorter AL or non-glaucomatous subjects in either AL group. These findings support the hypothesis that disturbed retinal autoregulation may be present in subjects with glaucoma with longer AL. Longitudinal studies are needed to further investigate whether axial elongation increases glaucoma risk by compromising retinal autoregulation.

Abstract
PURPOSE To determine the relationship between systemic factors and radial peripapillary capillary (RPC) vessel density (VD) in healthy African American (AA) participants of the African American Eye Disease Study. DESIGN A population-based, cross-sectional study. METHODS A total of 4135 eyes from 2127 AA participants aged 40 years and older in Inglewood, California, were imaged for 6×6-mm optic disc scans on a spectral-domain optical coherence tomography angiography (OCTA) device. Of these, 1029 eyes from 1029 participants who met the inclusion and exclusion criteria were analyzed, including only 1 eye per participant. Custom software was used to quantify RPC VD. Multivariate linear regression was used to identify systemic factors associated with RPC VD with a significance level set at 0.05. The contribution of each variable to the final model was estimated with the magnitude of standardized regression coefficients (SRCs). The fit of the final model was measured by R2. RESULTS The average RPC VD was 0.346±0.045. Controlling for signal strength, the systemic variables in the final multivariate model associated with reduced RPC VD were older age (β = -0.0123 per decade; SRC = -0.2733; P < .0001), male sex (β = -0.0067; SRC = -0.0716; P = .0060), and longer diabetes duration (β = -0.0022 per 5 years; SRC = -0.0527; P = .0427). The model R2 was 0.3689. CONCLUSIONS Age, sex, and systemic influences, such as diabetes duration, need to be considered when assessing changes in RPC VD in glaucoma and other ocular diseases. Longitudinal studies are needed to investigate whether reduced RPC VD and the factors that affect it are associated with an increased risk of developing glaucomatous nerve damage.

Abstract
INTRODUCTION Ankyloglossia is an oral anomaly characterized by a shortened, thickened lingual frenulum that may cause reduced tongue mobility. However, the diagnosis and management of this condition has long been a debated topic. Given the paucity of high level evidence, management can be frustrating for both families and clinicians. Our study aims to examine differences in the management of ankyloglossia and investigate influencing factors at a single tertiary pediatric referral center. METHODS A retrospective chart review was completed of children less than one year of age seen in the outpatient otolaryngology clinic. Billing records were searched for ICD-9 code 750.0 (ankyloglossia) between January 2, 2015 and October 9, 2017 and data extracted from the charts of those meeting inclusion criteria. RESULTS A total of 266 charts were reviewed that met the inclusion criteria during the study period. 100 (38%) were female with a mean age of 2.9 months. In the final multivariate regression model, children seen by providers in Group 1 (providers with high rates of frenotomies) had 4.4 times the odds of having a frenotomy as those seen by a provider in Group 2 (providers with low rates of frenotomies) (p < 0.001, 95%CI: 2.2, 8.9), and male children had 2.5 times the odds of having a frenotomy as female children (p = 0.002, 95%CI: 1.4, 4.5). CONCLUSION In this study we identify additional variables that may influence the decision to perform a frenotomy in children with ankyloglossia. The significant impact of clinician biases in the management of ankyloglossia suggests arbitrary differences in the way these patients are managed, highlighting the lack of consensus amongst otolaryngologists and the need for clear indications and diagnostic criteria.

Abstract
Purpose The African American (AA) population has unique ocular anatomic characteristics and a disproportionately high incidence of glaucoma, which is associated with lower peripapillary vessel density (VD). This study aimed to identify ocular determinants of peripapillary VD in healthy AAs. Methods This was a cross-sectional, population-based study of 1029 AAs, ages 40 and older. Participants underwent examination to obtain axial length (AL), IOP, central corneal thickness (CCT), mean retinal nerve fiber layer (RNFL) thickness, visual field mean deviation (MD), and 6 × 6-mm optical coherence tomography angiography scans of the optic nerve. Participants with glaucoma, vision-threatening diabetic retinopathy, or other relevant ocular disease were excluded. Prototype software was used to quantify VD. A multivariable regression model, controlling for age and signal strength, identified the ocular variables that predicted peripapillary VD. The contribution of each variable was assessed with the magnitude of standardized regression coefficients (SRC). Results Based on univariate regressions, AL, RNFL thickness, and MD had significant associations with peripapillary VD (all P < 0.001). In the final multivariate model, lower mean RNFL thickness (β = 0.0022, P < 0.001, SRC = 0.542) and longer AL (β = -0.0055, P < 0.001, SRC = -0.118) were associated with lower peripapillary VD, controlling for age and signal strength, with model R2 of 0.69. Conclusions Thinner RNFL and longer AL were the most influential ocular determinants of lower peripapillary perfusion in healthy AA eyes. Additional research is needed to clarify whether longer AL increases risk of glaucoma by affecting capillary perfusion.
