Publication rates of registered strabismus trials from ClinicalTrials.gov.

Presently, little is known regarding the characteristics and publication rates of registered strabismus trials from ClinicalTrials.gov. We queried registered strabismus trials that were completed prior to January 1, 2021, from ClinicalTrials.gov. Publication of trials in peer-reviewed journals was confirmed using PubMed.gov, ClinicalTrials.gov, and Google Scholar. Of the 117 trials found, only 69 (59%) were published with a publication delay of nearly 2.5 years. Interventional trials were associated with publication status compared with observational trials. The low publication rates and significant publication delay indicate potential bias in information dissemination of completed strabismus trials.

Teprotumumab for Thyroid Eye Disease-related Strabismus.

PURPOSE: To assess and quantify teprotumumab's effect on thyroid eye disease-related strabismus by change in measured horizontal and vertical deviations and change in extraocular motility. METHODS: We reviewed a series of patients with thyroid eye disease-related strabismus treated with teprotumumab. Exclusion criteria included age under 18 years, strabismus of alternate etiology, or thyroid eye disease-related reconstructive surgery during the treatment course. Primary outcomes were absolute (prism diopters) and relative (%) differences in horizontal and vertical deviations in primary position at distance, as well as change in ductions of the more affected eye. Secondary outcomes included incidence and timing of strabismus surgery postteprotumumab. RESULTS: Thirty-one patients were included, with mean age 63 years and thyroid eye disease duration 10 months. After teprotumumab, there was 6 prism diopters (39%) mean reduction in vertical deviation (p < 0.001), without significant change in mean horizontal deviation (p = 0.75). Supraduction, abduction, adduction, and infraduction significantly improved in the more restricted eye (p < 0.01, p < 0.01, p = 0.04, and p = 0.01, respectively). Thirty-five percent of patients underwent strabismus surgery posttreatment, at an average 10 months after last infusion. CONCLUSIONS: Teprotumumab produced a statistically significant reduction in vertical but not horizontal strabismus angles in primary position at distance. Extraocular motility in all 4 ductions also improved. A substantial minority of patients still required strabismus surgery following teprotumumab.

The influence of orbital architecture on strabismus in craniosynostosis.

PURPOSE: To better characterize the correlation of bony orbital dysmorphology with strabismus in craniosynostosis. METHODS: The medical records of patients with craniosynostosis with and without strabismus seen at Rady Children's Hospital (San Diego, CA) from March 2020 to January 2022 were reviewed retrospectively in this masked, case-control study. Computed tomography scans of the orbits were analyzed to obtain dimensions of the orbital entrance and orbital cone. Primary outcome was correlation of strabismus with orbital measurements. RESULTS: A total of 30 orbits from 15 patients with strabismus and 15 controls were included. Craniofacial disorders included in the study were nonsyndromic craniosynostosis (63%), Crouzon syndrome (13%), Apert syndrome (13%), and Pfeiffer syndrome (10%). Orbital index (height:width ratio) (P = 0.01) and medial orbital wall angle (P = 0.04) were found to differ significantly between the strabismus and control groups. CONCLUSIONS: In our small cohort, bony orbital dimensions, including the ratio of orbital height to width and bowing of the medial orbital wall, were associated with strabismus in craniosynostosis.

Teprotumumab-related Cutaneous Hypersensitivity Reactions.

The authors report 4 cases of cutaneous hypersensitivity reactions developing in the course of teprotumumab treatment for thyroid eye disease. The onset of the cutaneous hypersensitivity reaction was also observed during the treatment course in all cases, between the second and fifth infusions. Teprotumumab-related cutaneous reactions suggest a possible immunogenic component of the monoclonal antibody and highlight the importance of close monitoring during treatment.

Surgical and anesthetic influences of the oculocardiac reflex in adults and children during strabismus surgery.

One of the most common untoward occurrences during strabismus surgery at all ages is the oculocardiac reflex. Although typically easily treated, the sudden bradycardia or cardiac arrest may add a few gray hairs to ophthalmologists and anesthesiologists alike as it can be potentially fatal. This updated review of the literature and novel detailed treatment algorithm may prevent patient morbidity and mortality through proper recognition of at-risk patients and rapid treatment through proper communication between surgical and anesthesia physicians/providers.

The socioeconomic effect of COVID-19 on pediatric ophthalmologists: data from the first 12 months.

PURPOSE: To investigate the socioeconomic effect on pediatric ophthalmologists (POs) of the first year of the COVID-19 pandemic and to assess the association of practice type with financial impact. METHODS: An email follow-up survey of all AAPOS active members (POs) in April 2021, was used in conjunction with two prior surveys. The majority of US states were represented, and respondents were categorized as academic/university (AU), hospital employee (H), or one of three types of private practice: multispecialty ophthalmology practice (MSP), pediatric ophthalmology/strabismus group (PG), or solo practice (SP). RESULTS: The cumulative results during this one-year period revealed 1,533,203 examinations not performed, of which 498,291 were Medicaid. Over 65,000 surgeries were not performed. The average salary loss per PO was $57,188. The total loss of revenue for the pediatric ophthalmology sector was over $303,788,000. Practice groups making at least 75% of their prior year revenue were as follows: H, 81%; AU, 64%; MSP, 52%; PG, 50%; SP, 40%. Salary reduction in each group was as follows: H, 4.2%; AU, 15.4%; MSP, 17.2%; PG, 23.1%; SP, 40.9%. The average loss per practice was $290,151. More than 95% of private practice POs received funds from the Paycheck Protection Program. CONCLUSIONS: At the one-year mark of the pandemic, patient care had been severely disrupted, with subsequent financial consequences. Private practice providers (and especially solo practices) were disproportionally negatively affected.

As the worm turns: An infant with exotropia.

A two-year-old full-term boy with a history of an intermittent exotropia presented to the pediatric ophthalmology clinic for routine follow-up. He was found to have a stable sensorimotor examination however dilated funduscopic examination of the right eye was significant for a dim foveal reflex with a new discrete, white, elevated retinal lesion superotemporal to the fovea with surrounding subretinal exudates. An examination under anesthesia (EUA) was performed two days later that revealed a subretinal posterior pole granuloma with hyperfluorescence and late leakage from the lesion without telangiectatic vessels on fluorescein angiography. A repeat EUA one month later demonstrated an increase in surrounding subretinal and overlying intraretinal fluid. The patient was started on topical 1% prednisolone with a presumed diagnosis of Toxocara granuloma. At EUA, three months later, the subretinal and intraretinal fluid had resolved. The topical steroids were tapered, and the patient continues to be followed closely.

Socioeconomics of retinopathy of prematurity screening and treatment in the United States.

BACKGROUND: Retinopathy of prematurity (ROP) screening, an integral part of pediatric ophthalmology, can be time consuming and resource intensive. The purpose of this study was to evaluate the economic landscape of ROP screening and treatment among pediatric ophthalmologists in the United States. METHODS: An online survey was distributed to US pediatric ophthalmologists through a pediatric ophthalmology email listserv. Survey results were compiled, and responses were deidentified and analyzed, with particular focus on factors affecting financial compensation. RESULTS: A total of 97 responses were collected. Almost half of respondents worked in private practice settings. Over 80% of respondents had a formal contract to perform ROP care, but only 26% enlisted the assistance of an attorney to negotiate their contract. Just over half of respondents believed themselves adequately compensated for their services. Respondents that had retained an attorney for contractual negotiations were more likely to have a higher mean annual compensation rate ($126,545 ± $145,133 vs $70,214 ± $50,671; P = 0.05). Physicians who believed themselves adequately compensated were more likely to be in academic practice settings (78% academic vs 55% combo/other vs 24% private; P < 0.001) and were more likely to have contracts to perform ROP care (68% with contracts vs 15% without; P = 0.001). Average annual compensation was $82,968 ± $84,132, approximately $24,000 higher than reported in 2013. CONCLUSIONS: More pediatric ophthalmologists among our respondents obtained contracts for their services, and compensation rates have increased since 2013. Nevertheless, concerns regarding under-compensation and time commitment persist, raising concerns about the long-term sustainability of current models for providing ROP services.

The impact of the COVID-19 shutdown on US pediatric ophthalmologists.

In recent months, the COVID-19 pandemic has threatened the financial viability of pediatric ophthalmology practices. To measure the economic impact, the American Association of Pediatric Ophthalmology and Strabismus (AAPOS) Socio-economic Committee surveyed current US members at the peak of the COVID shutdown, in April 2020. With a robust response rate, the survey portrays that some pediatric ophthalmology practices are ominously strained, if not irreparably harmed.

Fetal Ultrasound and Magnetic Resonance Imaging Findings in Suspected Septo-Optic Dysplasia: A Diagnostic Dilemma.

OBJECTIVES: To investigate prenatal imaging findings supporting a diagnosis of suspected septo-optic dysplasia (SOD) by fetal ultrasound (US), magnetic resonance imaging (MRI), or both. METHODS: A retrospective review identified 11 patients with SOD: 9 had a clinical diagnosis of SOD postnatally, and 2 were terminated on the basis of suspicious prenatal imaging. Prenatal and neonatal imaging of the cavum septi pellucidi (CSP), frontal horns (FHs), and lateral ventricles was evaluated. RESULTS: The appearance of the CSP varied on US and MRI. Complete ("fused") FHs or partial absence of the CSP was reported in 6 of 11 patients by fetal US and 7 of 8 patients by fetal MRI. The diagnosis of SOD was prospectively suspected prenatally in 6 of 11 and in an additional 5 of 11 cases retrospectively. Fetal MRI incorrectly initially reported normal morphologic abnormalities for 2 cases with partial absence of the CSP, whereas US accurately identified the morphologic abnormalities in 1 of these cases before MRI. Imaging features were first suggested at anatomic US (4 patients) and follow-up prenatal US (2 patients). Neonatal imaging was concordant in all 9 live births: 5 completely absent CSP, 3 partially absent CSP, and 1 completely present CSP. Clinical manifestations included optic nerve hypoplasia (9 of 9), panhypopituitarism (5 of 9), and neurodevelopmental delays. CONCLUSIONS: Primary imaging features of SOD are "continuous" FHs with complete or partial absence of the CSP. Septo-optic dysplasia can be suspected in utero and can appear isolated but has substantial associated central nervous system anomalies identified on fetal MRI or after birth. Partial absence of the CSP can be a prenatal sign of suspected SOD, although fetal MRI lacked the spatial resolution to identify it accurately in all cases.

Bilateral abducens nerve palsy due to septic thrombophlebitis.

PURPOSE: To report a case of septic thrombophlebitis producing bilateral abducens nerve palsy. OBSERVATION: A 65 year-old woman with recent sinus surgery experienced the onset of horizontal diplopia during treatment for bacteremia. Computer tomography of head and a neck ultrasonography showed right internal jugular vein occlusion. Ophthalmology examination was consistent with bilateral abducens nerve palsy. She was treated with systemic antibiotics and antiplatelet therapy with resolution of the internal jugular vein occlusion. The diplopia improved over a six-months. CONCLUSION AND IMPORTANCE: Our patient had Lemierre syndrome with an unusual presentation. The patient was treated for septic thrombophlebitis with a resolution of her ocular symptoms.

Comparison of Digital Widefield Retinal Imaging With Indirect Ophthalmoscopy in Pediatric Patients.

BACKGROUND AND OBJECTIVE: Approximately 16,000 children in the United States lose vision each year because of retinal disease. The authors compare digital ultra-widefield (UWF) photography to indirect ophthalmoscopy in children. PATIENTS AND METHODS: Prospective, single-center study of patients ages 3 to 17 years. Retinal area during indirect ophthalmoscopy was compared with retinal area in digital UWF fundus photographs. Image quality was graded. A survey to assess the usefulness of the retinal image was obtained. RESULTS: The retinal area (mean ± standard deviation, mm2) evaluated with indirect ophthalmoscopy was 413 ± 194 mm2, compared with 652 ± 117 mm2 with widefield photography (P < .001). The difference was largest in children younger than 14. Image quality was significantly associated with patient cooperation. CONCLUSIONS: High-quality UWF photographs evaluate more peripheral retina than the in-office dilated funduscopic exam in children under 14. Photography assisted with family counseling in 17% of patients and the avoidance of examination under anesthesia in 2% of patients. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:580-585.].

Anticoagulation: a practical guide for strabismus surgeons.

An increasing number of surgical strabismus patients are taking oral anticoagulant and antiplatelet agents, with more diverse mechanisms of action than those used in the past. The decision as to whether to continue these drugs throughout the perioperative period is difficult and must be based on the balance between hemorrhagic and thrombotic risk. To help guide strabismus surgeons with clinical management in these cases, we review potential hemorrhagic complications of strabismus surgery and examine the use of anticoagulant and antiplatelet drugs during the perioperative period. Surgical strategies that might help minimize intraoperative hemorrhage in patients on anticoagulant therapy are also discussed.

Time Requirements of Paper-Based Clinical Workflows and After-Hours Documentation in a Multispecialty Academic Ophthalmology Practice.

PURPOSE: To assess time requirements for patient encounters and estimate after-hours demands of paper-based clinical workflows in ophthalmology. DESIGN: Time-and-motion study with a structured survey. METHODS: This study was conducted in a single academic ophthalmology department. A convenience sample consisted of 7 attending ophthalmologists from 6 subspecialties observed during 414 patient encounters for the time-motion analysis and 12 attending ophthalmologists for the survey. Outcome measurements consisted of total time spent by attending ophthalmologists per patient and time spent on documentation, examination, and talking with patients. The survey assessed time requirements of documentation-related activities performed outside of scheduled clinic hours. RESULTS: Among the 7 attending ophthalmologists observed (6 men and 1 woman), mean ± SD age 43.9 ± 7.1 years, during encounters with 414 patients (57.8 ± 24.6 years of age), total time spent per patient was 8.1 ± 4.8 minutes, with 2.8 ± 1.4 minutes (38%) for documentation, 1.2 ± 0.9 minutes (17%) for examination, and 3.3 ± 3.1 minutes (37%) for talking with patients. New patient evaluations required significantly more time than routine follow-up visits and postoperative visits. Higher clinical volumes were associated with less time per patient. Survey results indicated that paper-based documentation was associated with minimal after-hours work on weeknights and weekends. CONCLUSIONS: Paper-based documentation takes up a substantial portion of the total time spent for patient care in outpatient ophthalmology clinics but is associated with minimal after-hours work. Understanding paper-based clinical workflows may help inform targeted strategies for improving electronic health record use in ophthalmology.

Identification and Correction of Restrictive Strabismus After Pterygium Excision Surgery.

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.

Ultrasonographic prenatal imaging of fetal ocular and orbital abnormalities.

Technological progress in medicine has provided earlier diagnosis, even into the prenatal period. We address ultrasonographic imaging of the prenatal eye and orbit. During development of these structures, multiple pathologies and diseases can arise. Orbital anomalies can be detected prenatally using ultrasound or magnetic resonance imaging. Some of these include congenital cataracts, hypertelorism, hypotelorism, dacryocystocele, microphthalmia, anophthalmia, orbital tumors/masses, and septo-optic dysplasia. We describe characteristic ultrasound findings of these diseases. Prenatal ocular and orbital diagnosis is best facilitated by a team approach between ophthalmology, radiology, obstetrics, neonatology, and genetic counselors to optimize diagnostic accuracy, familial expectations, and early treatment.

Ptosis Shmosis.

A 10-year-old girl presented with painless unilateral left upper lid ptosis. A nontender hard mass was palpated in the left upper lid. Blood smear was compatible with the diagnosis of leukemia. The cause of ptosis was now thought to be a mass composed of myeloid blast cells (myeloid sarcoma).

Ophthalmic manifestations of tuberous sclerosis: a review.

Tuberous sclerosis or tuberous sclerosis complex (TSC), one of the phakomatoses, is characterized by hamartomas of the heart, kidney, brain, skin and eyes. Ophthalmologic examinations are required in all cases of TSC. Retinal hamartomas are the most common ocular finding in tuberous sclerosis. The majority of hamartomas are non-progressive; however, lesions with subretinal fluid and progression have been reported. This paper details the genetics, clinical features and ocular findings of TSC and reviews potential therapeutic options for ophthalmic manifestations.
