Background

To prospectively investigate the safety, tolerability and 24-h intraocular pressure (IOP) patterns in patients with thyroid eye disease (TED) using a contact lens sensor (CLS).

Design

Prospective study.

Participants

Ten patients with established TED.

Methods

Ten eyes of 10 patients were prospectively evaluated in an ambulatory 24-h IOP monitoring session using the CLS (Sensimed AG, Lausanne, Switzerland). Patients pursued daily activities, and sleep behaviour was uncontrolled.

Main outcome measures

Incidence of adverse events (AEs) and tolerability (scale of 0-10, increasing intolerance) were assessed. IOP patterns were evaluated using a cosinor rhythmometry model, and linear regression slopes were constructed for the transition from wake/sitting (W/S) to sleep/supine (S/S) and vice versa.

Results

Mean age was 61.8 ± 21.6 years, and 90% of patients were female. Main AEs were blurred vision (50%), conjunctival hyperaemia (100%) and superficial punctate keratitis (20%). Tolerability of the lens was found to be 1.5 ± 0.7. Positive linear slopes of the CLS signal from wake to sleep were detected (18.0 ± 43.8 arbitrary units [a.u.]; P = 0.254), whereas at the transition from S/S to W/S a significant decrease (-62.9 ± 56.8 a.u.; P = 0.010) was found. Five patients (50%) had a significant nocturnal/sleep acrophase with the peak occurring at 6:30 a.m. The mean amplitude of the 24-h curves was 102.2 ± 52.6 a.u.

Conclusions

In patients with TED, the CLS provides a safe and well-tolerated approach to 24-h IOP monitoring. After modelling the 24-h IOP curves, TED patients were found to have a morning acrophase.

Purpose

To report the characteristics of patients with restrictive diplopia following pterygium excision and a successful treatment approach for the strabismus.

Design

Retrospective interventional case series.

Methods

This study was set in a single academic institution and included 15 patients with restrictive diplopia after pterygium excision. Patients with any other reason for strabismus were excluded. Patients were evaluated for deficits with special attention to diplopic measures. The intervention was a combined procedure by a strabismologist and oculoplastic surgeon to correct the diplopia. The primary outcome measurements were subjective and objective improvement of diplopia.

Results

Fifteen patients (mean age = 49 years) who developed diplopia after pterygium excision were included. Mean time to diplopia was 6 months. All patients had limited abduction in the previously operated eye causing esotropia in the abductive field (mean deviation = 18 prism diopters). After intervention, all patients were no longer diplopic in primary gaze. In the abductive field, 11 (73%) patients had residual small angle esotropia (mean = 7 prism diopters) in ipsilateral extreme end-gaze only. Only 2 patients required additional surgical intervention for scar tissue removal. No patients underwent medial rectus recession.

Conclusions

Restrictive diplopia is a potential complication after pterygium excision, particularly for patients with a history of recurrent pterygia requiring multiple excisions and previous amniotic membrane graft placement with fibrin glue. However, diplopia after pterygium excision in primary position is surgically correctable with scar tissue removal and ocular surface reconstruction, without needing medial rectus recession. Given the high volume of pterygium excision, awareness of postoperative restrictive strabismus and the potential for correction is critical.

Purpose

Despite increasing electronic health record (EHR) adoption, perceptions of EHRs are negative among ophthalmologists due to concerns about productivity, costs, and documentation. The authors evaluated the effects of EHR adoption in an oculoplastics practice, which had not been previously studied.

Methods

Clinical volume, documentation time, time spent with patients, reimbursement, relative value units, and patient satisfaction were examined for 2 academic oculoplastics attendings between April 2018 and April 2019, with EHR implementation in September 2018.

Results

The mean number of patients seen in a half-day clinic was 31.8 versus 27.7 (p = 0.018) pre- and post-EHR implementation, respectively. EHR implementation had no effect on total monthly reimbursement (p = 0.88) or total monthly relative value units (p = 0.54). Average reimbursement (p = 0.004) and relative value units (p = 0.001) per patient encounter were significantly greater with EHR use. Patient satisfaction scores improved (p = 0.018). Mean physician time per patient increased from 6.4 to 9.0 minutes (p < 0.001). Mean documentation time per patient increased from 1.7 to 3.6 minutes (p < 0.001). Average patient wait times decreased by 9 minutes (p = 0.03) with EHR use. No scribes were used.

Conclusions

EHR implementation was associated with decreased patient volume without significant differences in total reimbursement. Although EHR adoption was associated with increased physician time devoted to patients and greater time expenditure on documentation, patients experienced decreased wait times. This suggests that EHR use streamlined the overall clinic flow without sacrificing physicians' time with the patient. The author's findings suggest that EHR implementation can be accomplished in an academic oculoplastics setting without negative impact on patient experience or reimbursement considerations.

Purpose

To identify common factors associated with the loss of an eye using the NIH All of Us database.

Methods

In this case-controlled study, we extracted electronic health record and socio-demographic data for 231 cases of eye loss from All of Us enrollment sites. Controls (N = 924) matched the demographic characteristics of the 2020 United States Census. Bivariate analyses and multivariable logistic regression identified variables significantly associated with increased odds of eye loss.

Outcome measures

Medical and social determinants associated with increased odds of losing an eye.

Results

Among cases, the average age (standard deviation) was 60.1 (14.4) years. The majority (125, 54.1%) were male. 87 (37.7%) identified as African American, and 49 (21.2%) identified as Hispanic or Latino. Loss of eye was more likely in those with ocular tumor (odds ratio [OR] 421.73, 25 95% confidence interval [CI] 129.81-1959.80, p < .001), trauma (OR 13.38, 95% CI 6.64-27.43, p < .001), infection (OR 11.46, 95% CI 4.11-32.26, p = .001) or glaucoma (OR 8.33, 95% CI 4.43- 15.81, p < .001). African American (OR 2.39, 95% CI 1.39-4.09, p = .002) and Hispanic or Latino (OR 1.80, 95% CI 1.01-3.15, p = .04) participants were disproportionately affected.

Conclusions

Racial and ethnic disparities exist among those with loss of an eye from underlying conditions. Addressing health inequities may mitigate the risk of this morbid outcome.

Objective

This study utilized Next Generation Sequencing (NGS) to identify differentially expressed transcripts in orbital adipose tissue from patients with active Thyroid Eye Disease (TED) versus healthy controls.

Method

This prospective, case-control study enrolled three patients with severe, active thyroid eye disease undergoing orbital decompression, and three healthy controls undergoing routine eyelid surgery with removal of orbital fat. RNA Sequencing (RNA-Seq) was performed on freshly obtained orbital adipose tissue from study patients to analyze the transcriptome. Bioinformatics analysis was performed to determine pathways and processes enriched for the differential expression profile. Quantitative Reverse Transcriptase-Polymerase Chain Reaction (qRT-PCR) was performed to validate the differential expression of selected genes identified by RNA-Seq.

Results

RNA-Seq identified 328 differentially expressed genes associated with active thyroid eye disease, many of which were responsible for mediating inflammation, cytokine signaling, adipogenesis, IGF-1 signaling, and glycosaminoglycan binding. The IL-5 and chemokine signaling pathways were highly enriched, and very-low-density-lipoprotein receptor activity and statin medications were implicated as having a potential role in TED.

Conclusion

This study is the first to use RNA-Seq technology to elucidate differential gene expression associated with active, severe TED. This study suggests a transcriptional basis for the role of statins in modulating differentially expressed genes that mediate the pathogenesis of thyroid eye disease. Furthermore, the identification of genes with altered levels of expression in active, severe TED may inform the molecular pathways central to this clinical phenotype and guide the development of novel therapeutic agents.

Background

p16 expression is a well established biomarker of cervical dysplasia and carcinoma arising from high risk human papilloma virus infection. Increased p16 expression is also seen in squamous neoplasms arising at other sites, including head, neck, and oropharyngeal tract. Squamous lesions are also frequently encountered at ocular surface and peri-orbital skin sites, but the prevalence of increased p16 expression in these lesions has been poorly studied.

Methods

We retrospectively surveyed 13 ocular surface and 16 orbital squamous lesions biopsied at UC San Diego Healthcare System and VA San Diego Healthcare System for p16 expression by immunohistochemistry. These cases included ocular surface lesions with diagnoses of conjunctival intraepithelial neoplasm (CIN) and squamous cell carcinoma in situ. Peri-orbital eyelid biopsies included lesions with diagnoses of SCCis and invasive squamous cell carcinoma. We performed multivariate logistic regression, followed by student's T-test or Fisher's exact test to determine if there were statistically significant associations between p16 immunoreactivity and patient age, gender, diagnosis, and ethnicity. Statistical significance was defined as p < 0.05.

Results

We found an unexpectedly large prevalence of strong nuclear and cytoplasmic p16 immunoreactivity in our cases. Almost all of the ocular surface squamous lesions were diffusely positive for p16 expression (12/13). All of the periorbital lesions showed diffuse p16 immunoreactivity (16/16). Altogether, 28/29 lesions tested showed strong and diffuse p16 expression. We found no statistically significant correlation between p16 expression and patient age, gender, ethnicity, or diagnosis. In 6 of the peri-orbital biopsies, we had sufficient tissue to assess high-risk HPV expression by in situ hybridization. Interestingly, all of these cases were negative for HPV, despite strong p16 expression.

Conclusion

Strong p16 expression was observed in virtually all of the ocular surface and peri-orbital squamous neoplasms in our study. The relationship between p16 expression and HPV infection in ocular surface and peri-orbital sites requires further investigation.

Purpose

To explore if orbital fat-to-muscle ratio (FMR) is predictive of whether surgical decompression or teprotumumab leads to greater proptosis reduction in thyroid eye disease (TED).

Methods

A single-center retrospective cohort study comparing surgical decompression with teprotumumab according to FMR. All TED patients completing an 8-dose course of teprotumumab between January 2020 and September 2022 and all patients undergoing bony orbital decompression from January 2017 to December 2019 were included. Subjects were excluded if they were <18 years, received both surgical decompression and teprotumumab, or lacked orbital imaging. The primary exposure variable was teprotumumab or surgical decompression. The secondary exposure variable was baseline FMR. The primary outcome measure was change in proptosis (mm).

Results

Thirty-eight patients, mean age 53.5 years (±11.4), were included in the teprotumumab group and 160 patients, mean age 48 years (±11.1), in the surgical group. Average proptosis reduction after teprotumumab and surgical decompression was 3 mm (±1.44) and 5 mm (±1.75), respectively. The FMR was stratified at the median of 1.80. In subjects with FMR < 1.80, teprotumumab showed equivalent proptosis reduction compared to surgical decompression, -0.33 mm (SE 1.32) p = .802. In subjects with FMR ≥ 1.80, surgical decompression led to significantly more proptosis reduction than teprotumumab, 3.01 mm (SE 0.54), p < .001.

Conclusions

Baseline FMR can be used to counsel patients as to proptosis reduction with teprotumumab versus surgery. Subjects with low FMR obtain comparable proptosis reduction with teprotumumab or surgery, whereas high FMR is associated with more significant proptosis reduction following surgery over teprotumumab.

Purpose

To assess the association between thyroid eye disease (TED) and glaucoma.

Methods

Patients 18 years of age and over enrolled in the NIH All of Us Research Program, a nationwide cohort, were extracted. Those with conditions relating to TED were identified and compared with 2020 US Census-matched controls without a diagnosis of TED in a 1:4 ratio. The authors used Pearson's χ 2 tests to study demographics by TED status, and logistic regression to generate odds ratios and 95% confidence intervals to evaluate the association between TED and glaucoma (any type, including glaucoma suspect), using those without TED as the reference group. Multivariable models were adjusted for age, gender, race/ethnicity, eye doctor visits, and smoking status.

Results

A total of 393 cases of TED and 1,572 US Census-matched controls were identified. The median age of the cohort was 63 years (interquartile range: 48-73 years). Age, gender, and race/ethnicity varied by TED status ( p < 0.001). Overall, 114 (29.0%) of TED cases had a diagnosis of glaucoma, compared with 94 (6.0%) of non-TED controls. On bivariate logistic regression models, those diagnosed with TED were significantly more likely to be diagnosed with glaucoma compared with controls (odds ratio: 6.42; 95% confidence interval: 4.76-8.70; p < 0.001). This trend persisted on multivariable logistic regression controlling for confounding factors (odds ratio: 3.37; 95% confidence interval: 1.85-6.20 p < 0.001).

Conclusions

Individuals with TED were significantly more likely to be diagnosed with glaucoma. Clinicians caring for patients with TED should be aware of this elevated risk and arrange glaucoma evaluation, accordingly.

Two fraternal twin sisters developed cysticercosis localizing to the right lateral orbit over the same period after a presumed common-source exposure in China. This case demonstrates that cysticercosis can be related to travel. Similar temporal and spatial occurrences of these infections suggest a genetic tropism of the infecting organism in these twins.

Objective

To evaluate informatics-enabled quality improvement (QI) strategies for promoting time spent on face-to-face communication between ophthalmologists and patients.

Methods

This prospective study involved deploying QI strategies during implementation of an enterprise-wide vendor electronic health record (EHR) in an outpatient academic ophthalmology department. Strategies included developing single sign-on capabilities, activating mobile- and tablet-based applications, EHR personalization training, creating novel workflows for team-based orders, and promoting problem-based charting to reduce documentation burden. Timing data were collected during 648 outpatient encounters. Outcomes included total time spent by the attending ophthalmologist on the patient, time spent on documentation, time spent on examination, and time spent talking with the patient. Metrics related to documentation efficiency, use of personalization features, use of team-based orders, and note length were also measured from the EHR efficiency portal and compared with averages for ophthalmologists nationwide using the same EHR.

Results

Time spent on exclusive face-to-face communication with patients initially decreased with EHR implementation (2.9 to 2.3 minutes, p = 0.005) but returned to the paper baseline by 6 months (2.8 minutes, p = 0.99). Observed participants outperformed national averages of ophthalmologists using the same vendor system on documentation time per appointment, number of customized note templates, number of customized order lists, utilization of team-based orders, note length, and time spent after-hours on EHR use.

Conclusion

Informatics-enabled QI interventions can promote patient-centeredness and face-to-face communication in high-volume outpatient ophthalmology encounters. By employing an array of interventions, time spent exclusively talking with the patient returned to levels equivalent to paper charts by 6 months after EHR implementation. This was achieved without requiring EHR redesign, use of scribes, or excessive after-hours work. Documentation efficiency can be achieved using interventions promoting personalization and team-based workflows. Given their efficacy in preserving face-to-face physician-patient interactions, these strategies may help alleviate risk of physician burnout.
