Retrospective Optimization of the Hawkeye Orbital Fracture Prioritization and Evaluation Algorithms for Triaging Ophthalmic Care

Objectives

Many orbital fracture patients are transferred to tertiary care centers for immediate ophthalmology consultation, though few require urgent ophthalmic evaluation or intervention. This overutilizes limited resources and overburdens patients and the health care system with travel and emergency department (ED) expenses. A simple, easy-to-use, clinical decision-making tool is needed to aid local EDs and triage services in effectively identifying orbital fracture patients who need urgent ophthalmic evaluation.

Design

Single center, retrospective cohort study.

Subjects

Orbital fracture patients aged ≥ 18 years who presented to the study institution's emergency department and received an ophthalmology consultation.

Methods

Ocular injuries that required close monitoring or an intervention within the first few hours after presentation were termed urgent. Two Hawkeye Orbital Fracture Prioritization and Evaluation (HOPE) algorithms were developed to identify orbital fracture patients needing urgent evaluation; including 1 algorithm incorporating computerized tomography (CT) scans interpreted by ophthalmology (HOPE+CT). Algorithms were compared with 3 previously published protocols: the University of Texas Health Science Center at Houston (UTH), the South Texas Orbital Fracture Protocol (STOP), and Massachusetts Eye and Ear (MEE) algorithms.

Main Outcome Measures

Correct triage of patients with orbital fractures who have urgent ocular or orbital conditions.

Results

In the study institution's ED, 134 adult patients (145 orbits) were seen with orbital fractures in 2019. Eighteen (13.4%) had ocular or orbital conditions categorized as urgent. The HOPE tool resulted in 100% sensitivity and 78.4% specificity. The HOPE+CT tool resulted in 100.0% sensitivity and 94.0% specificity. The UTH algorithm was 91.7% sensitive and 76.5% specific. South Texas Orbital Fracture Protocol and MEE were both 100% sensitive but only 35.1% and 32.8% specific, respectively.

Conclusions

The HOPE and HOPE+CT algorithms were superior or equal to the UTH, STOP, and MEE algorithms in terms of specificity while detecting all urgent cases. Implementation of a triage protocol that uses the HOPE or HOPE+CT algorithms could improve resource utilization and reduce health care costs through identification of orbital fracture patients needing urgent evaluation. An online tool that deploys the HOPE+CT algorithm in a user-friendly interface has been developed and is undergoing prospective validation before public dissemination.

Echographic characterization of extraocular muscles in pediatric patients with thyroid dysfunction

PURPOSE

To characterize the size of extraocular muscles (EOMs) in a pediatric population with thyroid dysfunction using orbital echography.

METHODS

Patients under age 18 with thyroid dysfunction who presented to an academic ophthalmology department from 2009 to 2020 and received orbital echography were included in this IRB-approved retrospective study. Data collected included age, clinical activity score (CAS), thyroid stimulating immunoglobulin (TSI), and extraocular recti muscle thickness on echography. Patients were organized into three age cohorts, after which statistical analysis compared recti measurements to previously reported normal ranges.

RESULTS

Twenty patients with thyroid dysfunction were included. When comparing average recti muscle thicknesses of study patients to those of previously published normal children in similar age ranges, the levator-superior rectus complex was significantly increased in all age groups of children with thyroid dysfunction (p-values = <.004), and the levator-superior rectus complex was most frequently enlarged compared to published normal values (78% of eyes). CAS was not correlated with EOM size in the youngest group (5-10 years old, p-values >.315) but was significantly correlated in older groups (11-17 years old, p-values <.027). TSI was not correlated with EOM size in any group (p-values >.206).

CONCLUSIONS

Echographic reference ranges for EOMs in children with thyroid dysfunction were established. There are increased rates of levator-superior rectus complex enlargement in children with TED compared to adults with TED, and EOM size is correlated with CAS in children older than 10 years. Though limited, these findings may serve as an additional tool for ophthalmologists to ascertain disease activity in pediatric patients with thyroid dysfunction.

Orbital and Optic Nerve Sheath Involvement and Pupil-Involving Cranial Nerve 3 Palsy in Giant Cell Arteritis

Giant cell arteritis (GCA) can present with atypical presentations that are diagnostically challenging. An 84-year-old woman with a history of breast adenocarcinoma treated with lumpectomy and radiation 2 years prior presented with a seizure-like episode.

Frequency and Patterns of Hearing Dysfunction in Patients Treated with Teprotumumab

PURPOSE

To better characterize the frequency and patterns of hearing dysfunction in patients who have received teprotumumab to treat thyroid eye disease.

DESIGN

Noncomparative case series.

PARTICIPANTS

Patients who underwent audiology testing before and after completion of teprotumumab infusions.

METHODS

A review of patients who underwent audiology testing before and after completion of teprotumumab infusions was carried out. Additional audiogram testing during treatment was included when available. Hearing function was analyzed using audiogram data measuring threshold hearing levels at specific frequencies. Basic demographic data as well as information regarding otologic symptoms also were obtained and analyzed.

MAIN OUTCOME MEASURES

Hearing loss demonstrated by a significant change in decibel hearing thresholds or that meets criteria for ototoxicity.

RESULTS

Twenty-two patients (44 ears) were included in the study, with baseline and most recent audiology testing after treatment ranging from 84 days before to 496 days after treatment. Fifteen patients (30 ears) also underwent testing during treatment starting after the second infusion up until the day of, but before, the eighth infusion. Hearing loss after treatment met criteria for ototoxicity in 17 of the 44 ears (38.6%), with 11 of the 22 patients (50.0%) meeting criteria in at least 1 ear. The pure-tone average decibel hearing levels (HLs) across all 44 ears demonstrated hearing loss after treatment (P = 0.0029), specifically at high (P = 0.0008) and middle frequencies (P = 0.0042), but not at low frequencies (P = 0.8344). Patients who were older also were more likely to experience hearing loss after treatment (P = 0.0048).

CONCLUSIONS

Audiometric data demonstrate that teprotumumab influences hearing function, most significantly at higher frequencies and in older patients. Audiometric testing is critical for counseling patients regarding teprotumumab treatment. A protocol for monitoring hearing during treatment is needed to detect and manage hearing changes associated with teprotumumab use.

Quantitative Assessment of Subjective Symptoms and Corneal Sensitivity in Chronic Orbital Pain Patients

PURPOSE

To objectively evaluate the subjective symptoms and characteristics of chronic orbital pain as well as to quantify sensitization of peripheral trigeminal nerves.

METHODS

In this prospective cohort study, patients who previously showed a response to peripheral trigeminal nerve blocks for unilateral, idiopathic chronic orbital pain and healthy subjects completed validated questionnaires assessing headaches, neuropathic signs and symptoms, photophobia, and pain qualities. Corneal sensitivity was measured in both eyes for all subjects with a Cochet-Bonnet aesthesiometer. For pain patients, the full assessment protocol was repeated 2-4 weeks after the study injection, and corneal sensitivity was also measured 30 minutes postinjection. Outcomes assessed were headache, neuropathic pain, and photophobia scores; pain qualities; and corneal sensitivity.

RESULTS

Six female chronic orbital pain patients (mean age 48.2 years) and 11 female controls (mean age 47.5) were included. The mean headache, neuropathic pain, and photophobia questionnaire scores were significantly higher for pain patients than for controls (p < 0.001). On sensory testing, 5 pain patients (83.3%) endorsed allodynia, and all 6 (100%) had hyperalgesia in the ipsilateral frontal nerve dermatome. No controls had allodynia or hyperalgesia. Corneal sensitivity was similar between eyes in pain patients and between groups. Questionnaire scores and corneal sensitivity did not change significantly after the injection.

CONCLUSIONS

Chronic orbital pain patients have a measurable reduction in quality of life due to headaches and photophobia. The supraorbital and supratrochlear nerves are sensitized, resulting in cutaneous hypersensitivity in the corresponding dermatome, but corneal nerves have normal sensitivity.

Misdiagnosis of fungal infections of the orbit

OBJECTIVE

To evaluate the accuracy of the initial diagnosis in the case of fungal infections of the orbit and identify factors that may influence patient outcomes.

METHODS

An institutional review board-approved retrospective chart review was conducted across 2 large academic centres to identify cases of fungal infections involving the orbit from January 1, 1998, to November 15, 2019. Data collected included patient demographics, past medical history, examination findings, diagnosis, treatment, imaging, and outcomes.

RESULTS

Fifty cases of fungal infection involving the orbit were identified. Of these, 33 (66.0%) were initially misdiagnosed as nonfungal diagnoses. Sixteen patients (32.0%) received multiple initial diagnoses. The most common diagnoses on presentation were bacterial cellulitis (n = 12 of 50; 24.0%) and bacterial sinusitis (n = 12 of 50; 24.0%). These were followed by vascular and orbital inflammatory conditions (n = 9 of 50; 18.0%): 5 patients (10.0%) were clinically diagnosed with giant cell arteritis, 3 (6.0%) with nonspecific orbital inflammation, and 1 (2.0%) with optic neuritis. In this subset of patients, 77.8% (n = 7 of 9) were treated initially with systemic steroids. Additional initial diagnoses included neoplastic mass lesions, mucocele, dacryocystitis, cavernous sinus thrombosis, hemorrhage, tick-borne illness, allergic rhinitis, and allergic conjunctivitis. Misdiagnosis was significantly correlated with involvement of the masticator space on imaging (p = 0.04).

CONCLUSION

Fungal infections of the orbit are misdiagnosed in 2 of 3 cases. Nearly 15% of patients who are later diagnosed with fungal disease of the orbit were initially treated with systemic steroids. Misdiagnosis is more frequent when the masticator space is involved.

Elevated Intraocular Pressure in Periorbital Sweet's Syndrome

A 66-year-old immunocompromised man presented with cellulitis around the left eye that was initially concerning for necrotizing fasciitis. Exam findings were remarkable for exquisite periocular tenderness with rigid, immobile eyelids resulting from severe erythema, edema, and induration. Given the concern for orbital compartment syndrome and a necrotizing infection, the patient was taken urgently to the operating room for debridement of the eyelid skin as well as an urgent lateral canthotomy and cantholysis. His eye exam revealed 360° of hemorrhagic chemosis, no relative afferent pupillary defect, and an ipsilateral elevated intraocular pressure of 35 mm Hg. No visual acuity measurement could be obtained secondary to the patient's altered mental status. His intraocular pressure normalized after treatment with antihypertensive drops and further extension of the canthotomy. Histopathological analysis showed extensive neutrophilic infiltrate of the dermis which was compatible with a diagnosis of Sweet's syndrome.

Update on thyroid eye disease: Regional variations in prevalence, diagnosis, and management

Thyroid eye disease (TED) is a rare disease that can lead to decreased quality of life, permanent disfigurement, and vision loss. Clinically, TED presents with exophthalmos, periorbital edema, extraocular muscle dysfunction, and eyelid retraction, and can lead to vision-threatening complications such as exposure to keratopathy and dysthyroid optic neuropathy (DON). Over the last several years, significant advancements have been made in the understanding of its pathophysiology as well as optimal management. Ethnic variations in the prevalence, clinical presentation, and risk of vision-threatening complications of TED are summarized, and risk factors associated with TED are discussed. Additionally, significant advances have been made in the management of TED. The management of TED traditionally included anti-inflammatory medications, orbital radiation therapy, orbital surgical decompression, and biologic therapies. Most recently, targeted therapies such as teprotumumab, an insulin-like growth factor-1 receptor antagonist, have been studied in the context of TED, with promising initial data. In this review, updates in the understanding and management of TED are presented with a focus on the international variations in presentation and management.

Association of Age-adjusted Charlson Comorbidity Index With Orbital Fungal Disease Outcomes

PURPOSE

To determine whether the age-adjusted Charlson comorbidity index (age-CCI) in sino-orbital fungal disease patients correlates with disease-specific mortality.

METHODS

Hospital billing systems at 2 academic institutions were queried for patients with ICD-9, ICD-10, and CPT codes used in fungal disease who also had orbital disease and significant visual loss. Thirty-two patients at Institution A and 18 patients at Institution B met the inclusion criteria of microbiologic or pathologic confirmation of fungal infection and completion of inpatient ophthalmology evaluation. Patients without radiographic abnormality in the sinus or orbit were excluded. Demographic, diagnostic, treatment, and outcome variables were recorded. Our primary outcome was death due to fungal disease.

RESULTS

Of the 50 medical records examined, 44 patients met the criteria for fungal-related death outcome on multivariate analysis. The regression coefficient for age-CCI and fungal-related mortality was 0.242 (95% CI, 0.012-0.779) with a p value of 0.038.

CONCLUSIONS

Age-CCI is significantly associated with fungal-related mortality. This relationship remains significant when controlling for 5 covariates of fungal organism phylum, presence or absence of CNS disease, exenteration, local treatment use, and presence or absence of an immunosuppressive diagnosis. Age-CCI shows promise as a clinical and research tool in the evaluation of invasive fungal disease involving the orbit.

Scleral Contact Lens as Initial Management in a Neonate With a Large Upper Eyelid Coloboma

A neonate presented with a large full-thickness upper eyelid coloboma with near-complete exposure of the cornea. After failing lubrication and a moisture chamber, he was fit with a customized scleral contact lens that protected the ocular surface. It was tolerated well, and ocular surface health was maintained for 13 months to permit the growth of eyelid tissue for future oculoplastic surgery. Delaying reconstruction by using scleral contact lenses as management for large eyelid colobomas has not been previously described. A temporizing measure such as this could be considered for large eyelid colobomas in neonates.

Trends in horizontal periocular asymmetry

OBJECTIVE

To determine whether there is laterality predominance in the horizontal dimensions of the periocular region.

DESIGN

Retrospective study.

PARTICIPANTS

Patients >18 years of age who presented to a single academic ophthalmology department. Exclusion criteria included history of facial trauma or surgery, aesthetic injections, or other periocular-altering processes.

METHODS

Standardized digital photographs were obtained, and periocular structures were measured with Image J software. The midline was defined as the midpoint between the medial canthi, and the distances measured include midline to medial canthus, pupil centre, lateral canthus, and lateral zygoma. The palpebral fissure width was calculated as the distance between the lateral canthus and medial canthus. Data analysis was done for the full cohort and subsequently according to patient-identified gender.

RESULTS

Periocular structures were measured in 83 patients (50 female and 33 male) with a mean age of 57.0 ± 16.2 years (range, 22-84 years). Right-sided predominance was found to be increasingly significant for the following variables: midline to pupil centre (31.34 mm vs 31.08 mm, p < 0.01), midline to lateral canthus (42.57 mm vs 42.23 mm, p < 0.005), and midline to lateral zygoma (65.70 mm vs 64.01 mm, p < 0.001).

CONCLUSIONS

Photographic analysis of adults with no periocular-altering history demonstrates that there is a right-sided predominance in the horizontal dimension of the midline to the pupil, lateral canthus, and zygoma with increasing significance. Asymmetry of horizontal periocular measurements was more prevalent in males.

The roles of sex and gender in women's eye health disparities in the United States

BACKGROUND

In the United States, women are at a higher risk of developing vision impairment or a serious eye disease (such as age-related macular degeneration, thyroid eye disease, or chronic dry eye disease) than men. Disparities in eye diseases due to biology widen even further when considering factors such as social determinants of health; gaps in research data, literature, and policy; insufficient provider and patient education; and limitations in screening and treatment options. Sex and gender disparities in eye health are clinically under-addressed and burdensome on both patient quality of life and the health care and economic systems, resulting in a pressing population health issue that negatively impacts women.

DESIGN

The Society for Women's Health Research convened a working group of expert clinicians, researchers, and patient advocates to review the current state of science regarding sex and gender disparities in women's eye health, identify knowledge gaps and unmet needs, and explore better means to advance research, improve patient care, and raise awareness of key issues.

DISCUSSION

The SWHR Women's Eye Health Working Group identified priority areas in research, clinical care, and education to reduce disparities and improve patient care in women's eye health. The working group recommends using a systems approach that incorporates a comprehensive research framework with a sex and gender lens to guide future work and that increases health care provider and public education, as well as engagement by expanding partnerships among ophthalmologic providers, researchers, and non-vision stakeholders.

Thyroid eye disease with choroidal folds

Purpose: To determine the clinical course of patients with chorioretinal folds (CRF) in thyroid eye disease (TED).Methods: A multi-center retrospective case series of patients with TED who developed CRF.Results: Ten patients (17 eyes) with CRF related to TED were identified. The mean age of presentation was 59.3 ± 8.3 years old. The majority of patients were male (70%), hyperthyroid (70%), hyperopic (53%), had a history of radioactive iodine (60%), and currently on methimazole treatment (30%). Three patients (3 eyes) had unilateral involvement of CRF with bilateral TED. The average clinical activity score was 3.6 ± 2.1 at the time of presentation. The most commonly enlarged extraocular muscles were medial (76%), inferior (64%), superior (64%) and lateral rectus (35%). Compressive optic neuropathy was seen in 47% of eyes. Treatment included oral prednisone (70%), orbital decompression (59%), thyroidectomy (20%) and tocilizumab (10%). The CRF did not resolve over a follow up period of 24.7 ± 23.7 months in 70% of eyes. There was no significant difference in average axial length (25.7 ± 4.9 mm) and optic nerve to optic strut distance (37.8 ± 3.9 mm) between patients with CRF and the eight age-and sex-matched TED control patients without CRF (p = 0.81 and 0.65 respectively). A univariable and multivariable analysis found an enlarged inferior rectus as a factor in TED patients with persistent CRF.Conclusions: CRF are often an indicator of visually threatening situations and often do not resolve despite treatment of TED.

Challenging the current treatment of residual postoperative ptosis: safety and efficacy of repeat Müller's muscle conjunctival resection

OBJECTIVE

To determine if repeat Müller's muscle conjunctival resection (MMCR) is a viable approach in the treatment of recurrent or residual eyelid ptosis.

METHODS

A retrospective review of patients who underwent repeat MMCR was performed using external photos obtained preoperatively, postoperatively, and at last follow-up. The marginal reflex distances (MRD1 and MRD2), brow position (BP), and tarsal platform show (TPS) were evaluated with digital image analysis. The change in upper eyelid height (MRD1) and TPS following repeat ptosis repair were the outcome measures.

RESULTS

Repeat MMCR was performed on 12 eyelids of 11 patients. Mean MRD1 elevation after initial MMCR was 1.6 mm (standard deviation [SD] = 1.0mm, p < 0.00001). Mean decrease in TPS was 1.9 mm (p = 0.04). There was no significant change in MRD2 (p = 0.36) or BP (p = 0.33) with initial MMCR. Mean interval between procedures was 12.8 months (range 2.3-48.0) and follow-up after repeat MMCR was 2.3 months. Total average follow-up after initial MMCR was 15.1 months. Mean elevation in MRD1 after repeat MMCR was 1.0 mm (SD = 0.8 mm, p < 0.002). Mean decrease in TPS was 1.0 mm (p = 0.03). There was no difference in MRD2 (p = 0.90) or BP (p = 0.53). There were no complications of repeat MMCR noted clinically or spontaneously reported, including no entropion, fornix foreshortening, or development of dry eye signs or symptoms.

CONCLUSION

Repeat MMCR significantly improves recurrent or residual ptosis after initial MMCR without significant adverse consequences. The degree of elevation with repeat MMCR was diminished when compared with initial MMCR.

Detection and Referral of Orbital and Ocular Injuries Associated With Intimate Partner Violence Following an Educational and Screening Initiative in an Emergency Department

Importance

Intimate partner violence (IPV) is a substantial cause of morbidity and mortality in the US. Previous studies indicate gaps in identifying and referring female patients with IPV-associated orbital and ocular injuries to ancillary services.

Objective

To determine the number of IPV-associated orbital floor fractures, zygomaticomaxillary complex (ZMC) fractures, and ruptured globes referred to ancillary services in adult female patients following an educational and screening intervention to health care professionals.

Design, Setting, and Participants

This single-center retrospective quality improvement analysis examined electronic medical records of adult female patients seen in a single level 1 trauma center emergency department and ophthalmology clinic between January 2015 and February 2019, after the initiative began. Female adults who sustained orbital floor fractures, ZMC fractures, or ruptured globes were included. Preinitiative data were previously collected between January 1995 and January 2015 on adult female patients and published. Data analysis for this study occurred from May 2020 to September 2020.

Interventions

A 2-part, ongoing initiative began January 2015. First, enhancement of IPV screening protocols in the emergency department was conducted. Second, an educational campaign on IPV injury patterns was presented to residents and faculty in ophthalmology, emergency, otolaryngology, and trauma departments.

Main Outcomes and Measures

Comparison of ancillary service involvement preinitiative (January 1995 to January 2015) and postinitiative (January 2015 to February 2019).

Results

A total of 216 adult female patients (mean [SD] age, 55.0 [22.7] years; age range, 18-99 years) sustained orbital floor or ZMC fractures postinitiative. A total of 22 of 216 (10.2%) sustained fractures from IPV compared with 31 of 405 (7.6%) preinitiative (95% CI, -2.2% to 7.3%; P = .28). Documented social work referrals (11 of 31 preinitiative vs 20 of 22 postinitiative; difference, 55% [95% CI, 35%-76%]; P < .001), homegoing safety assessments (1 of 31 preinitiative vs 18 of 22 postinitiative; difference, 79% [95% CI, 61%-96%]; P < .001), and law enforcement involvement (7 of 21 preinitiative vs 16 of 22 postinitiative; difference, 50% [95% CI, 26%-74%]; P < .001) were higher in patients who presented after the initiative with orbital floor and ZMC fractures. A total of 51 adult female patients (mean [SD] age, 57.7 [20.8] years; age range 20-93 years) sustained ruptured globes postinitiative. A total of 5 of 51 patients (9.8%) sustained injury due to IPV postinitiative, compared with 5 of 141 (3.5%) preinitiative (95% patients, -2.5% to 15.0%; P = .08).

Conclusions and Relevance

Following the start of the initiative, referral patterns of adult female patients with IPV-associated orbital fractures improved. Targeted IPV screening of patients with orbital and ocular injuries is essential for effective intervention.

A direct transcutaneous approach to infraorbital nerve biopsy

Purpose: To describe a novel transcutaneous infraorbital nerve biopsy technique which can be performed to aid in the diagnosis of perineural invasion (PNI) of facial cutaneous squamous cell carcinoma (SCC).Methods: A single-center retrospective chart review was performed. Patients diagnosed with SCC with PNI via an infraorbital nerve biopsy between February 2019 and February 2020 were included. Data collected consisted of patient demographics, medical history, clinical presentation and exam, histologic and radiographic findings, treatment, and outcomes.Results: Four patients (3 male, 1 female) met inclusion criteria. The mean age at diagnosis was 79.5 years (range 66-85 years). Three of the four patients had a history of facial skin lesions, including actinic keratosis and SCC, involving the nose, cheek, or ear. One patient had no history of cutaneous malignancy. All patients presented with cranial neuropathies, including total V2 hypoesthesia. The most common presenting symptom was facial pain, followed by diplopia, unilateral facial weakness, and hypoesthesia in the V1 and/or V2 distribution. Transcutaneous infraorbital nerve biopsy in all patients revealed squamous cell carcinoma with no biopsy complications.Conclusion: Definitive diagnosis of PNI can be challenging but is important to minimize tumor-related morbidity. Infraorbital nerve biopsy can establish this diagnosis, especially in the context of negative or indeterminate imaging findings. This work comprises the first description of a transcutaneous approach to infraorbital nerve biopsy, which is a minimally invasive technique that can be performed in an outpatient procedure suite with limited to no sedation.

Tools for Responding to Patient-Initiated Verbal Sexual Harassment: A Workshop for Trainees and Faculty

Introduction

Patients are the most common source of gender-based harassment of resident physicians, yet residents receive little training on how to handle it. Few resources exist for residents wishing to address patient-initiated verbal sexual harassment themselves.

Methods

We developed, taught, and evaluated a 50-minute workshop to prepare residents and faculty to respond to patient-initiated verbal sexual harassment toward themselves and others. The workshop used an interactive lecture and role-play scenarios to teach a tool kit of communication strategies for responding to harassment. Participants completed retrospective pre-post surveys on their ability to meet the learning objectives and their preparedness to respond.

Results

Ninety-one participants (57 trainees, 34 faculty) completed surveys at one of five workshop sessions across multiple departments. Before the workshop, two-thirds (67%) had experienced patient-initiated sexual harassment, and only 28 out of 59 (48%) had ever addressed it. Seventy-five percent of participants had never received training on responding to patient-initiated sexual harassment. After the workshop, participants reported significant improvement in their preparedness to recognize and respond to all forms of patient-initiated verbal sexual harassment (p < .01), with the greatest improvements noted in responding to mild forms of verbal sexual harassment, such as comments on appearance or attractiveness or inappropriate jokes (p < .01).

Discussion

This workshop fills a void by preparing residents and faculty to respond to verbal sexual harassment from patients that is not directly observed. Role-play and rehearsal of an individualized response script significantly improved participants' preparedness to respond to harassment toward themselves and others.

Responding to Patient-Initiated Verbal Sexual Harassment: Outcomes of a Pilot Training for Ophthalmologists

Background

Sexual harassment of physicians by patients is highly prevalent and rarely reported. Little is known on how to prepare physicians to handle verbal sexual harassment that detracts from their ability to provide care but does not meet the threshold for reporting.

Purpose

To assess the impact of a sexual harassment workshop and toolkit for ophthalmologists and ophthalmology trainees on responding to patient-initiated verbal sexual harassment.

Methods

A survey study of ophthalmology faculty, fellows, and residents who participated in workshops on responding to patient-initiated verbal sexual harassment was performed at an academic center. A toolkit of strategies for response was distributed. Volunteer participants completed a retrospective pretest-posttest evaluation at the conclusion of the workshop and follow-up survey 3 weeks after the workshops on whether they experienced harassment and intervened. The pretest-posttest surveys assessed the workshop's effect on ophthalmologists' perceptions of and preparedness to respond to sexual harassment in the moment using a 5-point Likert scale, including bystander intervention. Participants described their responses observing and/or experiencing patient-initiated sexual harassment in the 3 weeks following the workshop and whether they had intervened toward the harassment.

Results

Ophthalmologists (n=31) felt significantly more prepared to respond to patient-initiated sexual harassment directed towards themselves or a trainee in the moment after participating in the workshop (4.5 ± 1.63,) than before (3.0 ± 1.3) with a mean change of -1.6 (95% CI -2.2 to -.98, p<0.001). After the workshop 86.3% of participants felt mostly or completely prepared to respond to comments about their age, gender, marital status, appearance, attractiveness, a specific body part, and sexual or inappropriate jokes. Most participants (83.9%) said that they had not previously received training on techniques for responding to patient-initiated sexual harassment. Two-thirds (66.7%) of participants who experienced (n=8) or observed (n=13) harassment (n=15) following the workshop intervened. All participants who intervened toward patient-initiated harassment behavior after the workshop (n=10) found the Sexual Harassment Toolkit helpful in addressing harassment in the moment.

Conclusion

Participation in a brief skills-based workshop significantly improved ophthalmologists' preparedness to respond to verbal sexual harassment by patients.

Preserving Vision: Rethinking Burn Patient Monitoring to Prevent Orbital Compartment Syndrome

Burn patients receiving aggressive fluid resuscitation are at risk of developing orbital compartment syndrome (OCS). This condition results in elevated orbital pressures and can lead to rapid permanent vision loss. Risk factors and monitoring frequency for OCS remain largely unknown. A retrospective review was therefore conducted of admitted burn patients evaluated by the ophthalmology service at an American Burn Association verified Burn Treatment Center. Demographic, burn, examination, and fluid resuscitation data were compared using two-sided t-tests, Fisher's exact tests, and linear regression. Risk factors for elevated intraocular pressures (IOPs; a surrogate for intraorbital pressure) in patients resuscitated via the Parkland formula were found to be total body surface area (% TBSA) burned, resuscitation above the Ivy Index (>250 ml/kg), and Parkland formula calculated volume. Maximum IOP and actual fluid resuscitation volume were linearly related. Analysis of all patients with elevated IOP found multiple patients with significant IOP increases after initial evaluation resulting in OCS within the first 24 hours postinjury. While %TBSA, Ivy Index, and resuscitation calculated volume are OCS risk factors in burn patients, two patients with facial burns developed OCS (25% of all patients with OCS) despite not requiring resuscitation. Orbital congestion can develop within the first 24 hours of admission when resuscitation volumes are the greatest. In addition to earlier and more frequent IOP checks in susceptible burn patients during the first day, the associated risk factors will help identify those most at risk for OCS and vision loss.

A U.S. Survey of Sexual Harassment in Ophthalmology Training Using a Novel Standardized Scale

Objective

This study aimed to assess the frequency and severity of sexual harassment toward ophthalmology trainees.

Design

Present study is an anonymous retrospective online survey.

Participants

U.S. ophthalmology residents and fellows participated in this study.

Methods

Sexual harassment comments directed toward University of Iowa ophthalmology trainees and faculty members were compiled. Statements were ranked by severity to develop the Iowa Verbal Sexual Harassment Scale. A brief, anonymous online survey incorporating the scale was sent to all United States ophthalmology residency program directors to distribute among trainees. Participants rated the prevalence, severity, and frequency of verbal and physical sexual harassment during training.

Main Outcome Measures

Response to the survey questions on the prevalence, severity, and frequency of reporting of verbal and physical sexual harassment in ophthalmology training.

Results

Among 112 respondents (59 men and 53 women), 72 (64.3%) experienced sexual harassment in the workplace from patients (86.8% of women vs. 44.1% of men; p<0.0001, 95% confidence interval [CI]: 1.48-2.74). Trainees rarely experienced harassment by colleagues (10.7%) or supervisors (8.9%). Women experienced more severe and frequent sexual harassment compared with men, with 54.7% women and 30.5% men experiencing sexual harassment weekly (p = 0.013, 95% CI: 1.29-5.71). Unwanted touching was the most common physical harassment type. The trainees' threshold for reporting sexual harassment was higher than their worst actual experience (p< 0.0001, F(2,282) = 67.59). Few trainees formally reported verbal (6.3%) or physical sexual harassment (1.8%). Trainees most commonly responded to harassment by redirecting the harasser (67.9%). Only 33.9% of trainees rated their institution's sexual harassment training as helpful preparation for addressing harassment.

Conclusion

Most ophthalmology trainees experienced sexual harassment with almost all harassment coming from patients. Female trainees reported substantially greater severity and frequency of sexual harassment. There remains an unmet need for targeted response training in ophthalmology training programs.

Teprotumumab for Thyroid-Associated Ophthalmopathy

BACKGROUND

Thyroid-associated ophthalmopathy, a condition commonly associated with Graves' disease, remains inadequately treated. Current medical therapies, which primarily consist of glucocorticoids, have limited efficacy and present safety concerns. Inhibition of the insulin-like growth factor I receptor (IGF-IR) is a new therapeutic strategy to attenuate the underlying autoimmune pathogenesis of ophthalmopathy.

METHODS

We conducted a multicenter, double-masked, randomized, placebo-controlled trial to determine the efficacy and safety of teprotumumab, a human monoclonal antibody inhibitor of IGF-IR, in patients with active, moderate-to-severe ophthalmopathy. A total of 88 patients were randomly assigned to receive placebo or active drug administered intravenously once every 3 weeks for a total of eight infusions. The primary end point was the response in the study eye. This response was defined as a reduction of 2 points or more in the Clinical Activity Score (scores range from 0 to 7, with a score of ≥3 indicating active thyroid-associated ophthalmopathy) and a reduction of 2 mm or more in proptosis at week 24. Secondary end points, measured as continuous variables, included proptosis, the Clinical Activity Score, and results on the Graves' ophthalmopathy-specific quality-of-life questionnaire. Adverse events were assessed.

RESULTS

In the intention-to-treat population, 29 of 42 patients who received teprotumumab (69%), as compared with 9 of 45 patients who received placebo (20%), had a response at week 24 (P<0.001). Therapeutic effects were rapid; at week 6, a total of 18 of 42 patients in the teprotumumab group (43%) and 2 of 45 patients in the placebo group (4%) had a response (P<0.001). Differences between the groups increased at subsequent time points. The only drug-related adverse event was hyperglycemia in patients with diabetes; this event was controlled by adjusting medication for diabetes.

CONCLUSIONS

In patients with active ophthalmopathy, teprotumumab was more effective than placebo in reducing proptosis and the Clinical Activity Score. (Funded by River Vision Development and others; ClinicalTrials.gov number, NCT01868997 .).

Dermoid cysts: clinical predictors of complex lesions and surgical complications

PURPOSE

To evaluate the clinical characteristics and role of imaging in the evaluation of dermoid cysts and to determine predictors of cyst rupture during surgical excision of dermoid cysts.

METHODS

In this single-center, consecutive, nonrandomized comparative case series, the records of consecutive patients with suspected dermoid cysts who underwent surgery between January 1, 2000, and December 31, 2014, were reviewed retrospectively for demographic information, clinical findings, preoperative imaging, surgical details, and pathology reports.

RESULTS

A total of 100 patients were included. Cyst volume was similar between superomedial and superotemporal lesions (P = 0.61) but greater in patients >10 years of age (P < 0.001). Immobility of the cyst was present in all complex dermoids (4/4), but there was no difference in the mobility of superotemporal or superomedial cysts (P = 0.69). Forty-two patients underwent imaging; superomedial lesions were more likely to be imaged than superotemporal lesions (P = 0.073). All 4 patients with complex dermoids presented with orbital signs and underwent preoperative imaging. None of the remaining 38 patients who underwent imaging had orbital signs, and the results of imaging had no effect on surgical planning. Intraoperative cyst rupture occurred in 18 patients. There was no significant difference in cyst rupture between superotemporal and superomedial cysts (P = 0.452). Smaller cyst volume was associated more often with intraoperative cyst rupture (P < 0.001).

CONCLUSIONS

Preoperative imaging of superomedial and superolateral dermoid cysts is likely unnecessary unless associated with orbital signs. Intraoperative cyst rupture is not influenced by cyst location but does appear to be more likely in smaller cysts.

Split face evaluation of long-pulsed non-ablative 1,064 nm Nd:YAG laser for treatment of direct browplasty scars

PURPOSE

To investigate 1,064 nm long-pulse Nd:YAG laser for postoperative treatment of direct browplasty scars.

METHODS

Nine patients who underwent direct browplasty were enrolled in this prospective study. Subjects were randomized to unilateral laser treatment at 2-week intervals for six total treatments, with the contralateral scar used as a control. Prior to each treatment, subjects rated treated and control scars on overall cosmesis. Post-treatment, subjects rated each for erythema, swelling, discomfort, and perceived hair loss. Finally, examiners masked to treatment side were asked to judge side-by-side photographs of first and final visits for improvement and side effects.

RESULTS

Subjects rated the overall appearance of the treated scar significantly higher at the time of treatment number 5 (mean score 5.13 ± 2.03, P = 0.008) and treatment number 6 (6.25 ± 1.98, P = 0.005) compared to treatment 1 (3.75 ± 2.12); by contrast, they failed to rate the control scar more highly. On masked examination of photographs, the treated scar was selected as most improved 50.0 ± 12.5% of the time. Both subjects and graders reported side effects as transient and mild to moderate (mean score 1-4), with no reports of hair loss from either subjects or observers.

CONCLUSIONS

The 1,064 nm Nd:YAG laser provided significant improvement in scar cosmesis after direct browplasty, as rated by subject self-report, but not by masked observers, and appears to be a useful tool for increasing satisfaction among those dissatisfied with direct browplasty scars. Side effects-including erythema, edema, and discomfort-were transient and universally rated as mild to moderate. Lasers Surg. Med. 48:742-747, 2016. © 2016 Wiley Periodicals, Inc.

Perception of patient appearance following various methods of reconstruction after orbital exenteration

This article compares the perception of health and beauty of patients after exenteration reconstruction with free flap, eyelid-sparing, split-thickness skin graft, or with a prosthesis. Cross-sectional evaluation was performed through a survey sent to all students enrolled at the University of Iowa Carver College of Medicine. The survey included inquiries about observer comfort, perceived patient health, difficulty of social interactions, and which patient appearance was least bothersome. Responses were scored from 0 to 4 for each method of reconstruction and an orbital prosthesis. A Friedman test was used to compare responses among each method of repair and the orbital prosthesis for each of the four questions, and if this was significant, then post-hoc pairwise comparison was performed with p values adjusted using Bonferroni's method. One hundred and thirty two students responded to the survey and 125 completed all four questions. Favorable response for all questions was highest for the orbital prosthesis and lowest for the split-thickness skin graft. Patient appearance with an orbital prosthesis had significantly higher scores compared to patient appearance with each of the other methods for all questions (p value < 0.0001). Second highest scores were for the free flap, which were higher than eyelid-sparing and significantly higher compared to split-thickness skin grafting (p value: Question 1: < 0.0001; Question 2: 0.0005; Question 3: 0.006; and Question 4: 0.019). The orbital prosthesis was the preferred post-operative appearance for the exenterated socket for each question. Free flap was the preferred appearance for reconstruction without an orbital prosthesis. Split-thickness skin graft was least preferred for all questions.

Tarsoconjunctival crypts: unrecognized cause of chronic mucopurulent conjunctivitis

PURPOSE

To describe 3 patients with chronic mucopurulent conjunctivitis found to have an unrecognized sequestration of bacteria within tarsoconjunctival crypts of the upper eyelid.

DESIGN

Review of 3 noncomparative cases.

METHODS

settings: Institutional. study population: Three consecutive patients with tarsoconjunctival crypts. intervention procedure: Marsupialization of the individual crypts. main outcome measures: Resolution of chronic discharge and resolution of signs and symptoms.

RESULTS

One patient with Stevens-Johnson syndrome and 2 patients with floppy eyelids had chronic mucopurulent conjunctivitis that was refractory to multiple medical and surgical interventions. Retention of a yellowish coagulum within the fistulous tracts of the tarsal conjunctiva was the site of pathologic features in all patients. The diagnosis was confirmed by squeezing out of the coagulum from the fistulous tracts by pinching the eyelid horizontally. Pseudomonas aeruginosa was isolated in 1 patient and Staphylococcus aureus was isolated in the other 2 patients. A Bowman probe could be passed through the fistulous opening to unveil the full extent of the conjunctival tunnels on the epitarsal surface. Each tract was marsupialized, and no relapse was found during a follow-up period of 12 to 96 months.

CONCLUSIONS

Patients with chronic, relapsing, purulent conjunctivitis should have their upper eyelid everted to search for tarsoconjunctival crypts as the source of bacteria-laden coagulum. The formation of the crypts is likely the result of tarsal conjunctiva trauma with lamellar de-epithelialization, followed by re-epithelialization to form an epithelialized tunnel as a potential space for harboring bacteria. Marsupialization of the crypts obliterates the potential space and is curative.

The use of titanium T-plate as platform for globe alignment in severe paralytic and restrictive strabismus

PURPOSE

To evaluate the long-term effectiveness of improved ocular alignment using a suture/T-plate anchoring platform system.

DESIGN

Retrospective, noncomparative, interventional case series.

METHODS

setting: Institutional. study population: Seven consecutive patients with large angle deviations attributable to paralytic and/or restrictive strabismus managed jointly by orbital and strabismus surgeons. intervention procedure: The T-plate base is anchored to the orbital rim with the shaft projecting toward the orbital apex to simulate the origin of the affected muscle. A nonabsorbable suture serves as the coupling element linking the muscle insertion to the tip of the T-plate such that the suture coincides with the axis of the dysfunctional muscle and yields a pull vector to simulate the passive tensile force of the muscle. Information analyzed included patient demographics, etiology of strabismus and characteristics, prior muscle surgeries, secondary interventions, subjective appraisal of diplopia, and final ocular alignment measurements. main outcome measures: Subjective appraisal of diplopia, final ocular alignment in primary gaze, and late stability.

RESULTS

All 7 patients showed marked reduction in ocular deviation with a median change of 33 prism diopters (PD) and a range of 7 to 72 PD. For the 6 patients with medial rectus dysfunction, the final ocular alignment ranged from 6 to 18 PD of residual exotropia in primary gaze. The patient with sixth nerve palsy had 5 PD of residual esotropia. There were no failures after an average of 59.4 months of follow-up.

CONCLUSIONS

A globe tethering technique using a suture/titanium T-plate anchoring platform system effectively treats refractory cases of paralytic and restrictive strabismus with large angles of deviation.

Three-day application of topical ofloxacin reduces the contamination rate of microsurgical knives in cataract surgery

PURPOSE

To determine the rate of contamination of microsurgical knives during cataract surgery and the benefit of a 3-day versus a 1-hour preoperative application of topical ofloxacin in reducing the contamination rate.

DESIGN

Prospective, randomized controlled trial.

PARTICIPANTS

Seventy-eight eyes of 75 patients were randomly assigned to control (39 eyes) or study groups (39 eyes).

METHODS

All patients from both groups received 0.3% topical ofloxacin 1 hour before surgery, 5% povidone-iodine (PVI) scrub of the periorbital area, and 2 drops of PVI onto the ocular surface preoperatively. The patients in the study group also received ofloxacin 4 times a day for 3 days before surgery.

MAIN OUTCOME MEASURES

Microsurgical knives were placed in blood culture broth media immediately after the incision had been made. The number of positive cultures and types of bacteria isolated were determined.

RESULTS

Ten of 39 knives (26%) in the control group were found to be positive for bacterial growth compared with only 2 of 39 (5%) in the study group (P = 0.028).

CONCLUSIONS

The initial paracentesis incision frequently results in contamination of the microsurgical knife and may serve as a mechanism for introducing bacteria from the ocular surface into the anterior chamber. The application of topical ofloxacin for 3 days before surgery significantly reduces the contamination rate of the microsurgical knives, compared with a preoperative application of ofloxacin given 1 hour before surgery.

Antibiotic resistance patterns of ocular bacterial flora

PURPOSE

To determine the antibiotic susceptibility patterns of conjunctival bacterial flora isolated preoperatively from patients undergoing anterior segment surgery.

DESIGN

Prospective observational study.

PARTICIPANTS

One hundred fifty-six eyes from 139 patients scheduled for anterior segment surgery were enrolled over a 6-month period from August 2001 to February 2002.

METHODS

Conjunctival cultures were obtained on the day of surgery before povidone-iodine or antibiotic application.

MAIN OUTCOME MEASURES

Bacterial isolates were identified and tested for antibiotic susceptibility using the Kirby-Bauer disc-diffusion technique.

RESULTS

Among the 156 eyes studied, 36 were from patients who had undergone either bilateral surgery or more than one surgery in the same eye. Only the first eyes of the 120 patients that underwent initial ocular surgery were included in our analysis. Of these 120 eyes, 21 (18%) showed no bacterial growth. Of the 143 bacterial strains isolated from the remaining 99 eyes, 112 (78%) were coagulase-negative staphylococci (CNS). Among the CNS, greater than 90% were susceptible to cefotaxime, levofloxacin, imipenem, meropenem, vancomycin, and each of the aminoglycosides except neomycin. Between 70% and 90% of the CNS were susceptible to cefazolin, neomycin, ciprofloxacin, ofloxacin, norfloxacin, and chloramphenicol. Less than 70% of the isolated CNS were sensitive to the penicillin analogues, ceftazidime, erythromycin, and tetracycline.

CONCLUSIONS

Preoperative conjunctival isolates of CNS seem to be most sensitive to vancomycin, the aminoglycosides (except neomycin), and levofloxacin.

Risk factors for antibiotic-resistant conjunctival bacterial flora in patients undergoing intraocular surgery

BACKGROUND

The purpose of this study was to determine if patients with certain risk factors are more likely to harbor conjunctival bacterial flora resistant to multiple antibiotics.

METHODS

In this prospective study, detailed medical history and slit-lamp examination were performed on all patients prior to intraocular surgery. Patients with local risk factors were defined as those with chronic blepharitis, conjunctivitis or discharge. Those with systemic risk factors were patients with diabetes, autoimmune, immunodeficient or skin disorders, asthma and those taking immunosuppressant medications. Conjunctival cultures were obtained prior to preoperative antibiotics and povidone-iodine. Bacteria isolated were identified and antibiotic susceptibility was determined. Bacteria resistant to five or more antibiotics were defined as multi-resistant (MR).

RESULTS

Among the 207 patients enrolled in the study, 73 patients had local risk factors. Of these patients, 32 patients (44%) carried MR organisms, compared to 32 of the 134 patients (24%) without local risk factors (P=0.0049). Thirty-two of 71 patients (45%) with systemic risk factors harbored MR organisms, compared to 32 of 136 patients (24%) without systemic risk factors (P=0.0025). Seventeen of 93 patients (18%) who had neither local nor systemic risk factors had MR organisms on their conjunctiva. In contrast, 17 of the 30 patients (57%) with both local and systemic risk factors (57%) carried MR bacteria (P=0.0001).

CONCLUSION

Patients with local and/or systemic risk factors are more likely to harbor MR organisms. This may be one mechanism for the reported increased risk of postoperative endophthalmitis in this group of patients.

Prospective randomized comparison of 3-day versus 1-hour preoperative ofloxacin prophylaxis for cataract surgery

PURPOSE

To determine the efficacy of reducing conjunctival bacterial flora with topical ofloxacin when given for 3 days compared with 1 hour before surgery.

DESIGN

Prospective, randomized, controlled trial.

PARTICIPANTS

Ninety-two eyes from 89 patients were randomized to a control group (48 eyes) or study group (44 eyes).

METHODS

All patients from both groups received topical ofloxacin 0.3% 1 hour before surgery and a 5% povidone iodine scrub of the periorbital area before surgery. The patients in the study group received additional ofloxacin four times daily for 3 days before surgery.

MAIN OUTCOME MEASURES

Conjunctival cultures were obtained at five separate time points and were inoculated in solid and liquid culture media. The presence of bacteria was determined, quantified, and identified.

RESULTS

Forty-two percent of eyes in the control group had positive conjunctival culture immediately before surgery, compared with 19% of eyes in the study group (P < 0.05). Immediately after surgery, 34% and 14% of eyes had positive cultures in the control and study groups, respectively (P < 0.05). Quantitatively, fewer bacteria were isolated from eyes in the study group compared with those in the control group for culture samples that were obtained both before povidone iodine scrub and at the conclusion of surgery (P </= 0.05).

CONCLUSIONS

The application of topical ofloxacin for 3 days before surgery appears to be more effective in eliminating bacteria from the conjunctiva than an application of ofloxacin 1 hour before surgery.
