Superior Ophthalmic Vein Thrombosis Associated With Asymptomatic COVID-19 Infection.

Superior ophthalmic vein thrombosis is a rare condition scarcely described in clinical literature with potentially severe consequences including permanent vision loss. This report details the case of a 70-year-old woman who presented with acute binocular horizontal diplopia, relative proptosis of the OD by 4 mm, and pain OD. On exam, visual acuity was 20/20 OD and 20/30 OS with full extraocular movements. CT revealed proptosis OD with a thrombosed superior ophthalmic varix. Evaluation for etiology of hypercoagulability was unremarkable, although the patient did have an asymptomatic COVID-19 infection 1 month prior. To the authors' knowledge, this is the first reported case of superior ophthalmic vein thrombosis secondary to an asymptomatic COVID-19 infection.

Ophthalmic manifestations and management considerations for emerging chemical threats.

Chemical agents have been utilized for centuries in warfare and pose a health threat to civilians and military personnel during armed conflict. Despite treaties and regulations against their use, chemical agent exposure remains a threat and measures to understand their effects and countermeasures for systemic and organ-specific health are needed. Many of these agents have ocular complications, both acute and chronic. This mini-review focuses on key chemical agents including vesicants (mustards, lewisite), nerve agents (sarin, VX), knockdown gasses (hydrogen cyanide), and caustics (hydrofluoric acid). Their ophthalmic manifestations and appropriate treatment are emphasized. Acute interventions include removal of the source and meticulous decontamination, as well as normalization of pH to 7.2-7.4 if alteration of the ocular pH is observed. Besides vigorous lavage, acute therapies may include topical corticosteroids and non-steroid anti-inflammatory therapies. Appropriate personal protective equipment (PPE) and strict donning and doffing protocols to avoid healthcare provider exposure are also paramount in the acute setting. For more severe disease, corneal transplantation, amniotic membrane graft, and limbal stem cell transplantation may be needed. Orbital surgery may be required in patients in whom cicatricial changes of the ocular surface have developed, leading to eyelid malposition. Multidisciplinary care teams are often required to handle the full spectrum of findings and consequences associated with emerging chemical threats.

Efficacy of the Buried Temporary Suture Tarsorrhaphy: A Novel Technique.

PURPOSE: To describe a buried variation of the temporary suture tarsorrhaphy and determine its efficacy period. METHODS: This retrospective case review includes 11 patients needing corneal protection. Six patients had lagophthalmos from facial nerve palsy, 4 had cicatricial ectropion, and 1 had neurotrophic keratopathy. A total of 14 buried temporary suture tarsorrhaphies (BTSTs) were placed. The duration of the BTST was the main outcome. The corneal status before and throughout the BTST was monitored. The eyelids were examined for any undesired changes from the BTST. RESULTS: The mean duration of the BTST was 97.5 days, with a maximum of 273 days. Aside from one spontaneous dehiscence 5 days after placement, all BTSTs held until intentional removal. Five BTSTs were removed for a more definitive surgical procedure, 6 were removed after resolution of the initial indication, and 2 are still in place as the patient awaits surgery. All cases of keratopathy improved after BTST placement. There were no complications and no undesired eyelid changes. CONCLUSIONS: The BTST is a simple, fast, safe, and effective procedure that can be performed in the clinic or inpatient to immediately improve ocular surface coverage. As a minimally invasive procedure that can easily last several months, the BTST is an excellent option for patients who require more intense intervention than medical management alone. It can also securely bridge patients to a permanent solution such as lateral canthal resuspension.

Orbital Wall Fractures and Ocular Injury: Impact on Management.

Background: Orbital wall fractures are often associated with concomitant ocular injury. In some cases, detection and treatment of such injuries requires ophthalmology evaluation. Study Objective: To identify a change in ocular management as a result of ophthalmology evaluation in patients with orbital wall fractures. Materials and Methods: Retrospective cohort, patients >18 years of age with orbital wall fracture, and prompt evaluation by an ophthalmologist from 2012 to 2020 in a tertiary Level 1 trauma center. Results: Fifty percent of patients had a moderate and/or severe ocular injury. Ophthalmology evaluation led to an ocular management change in 27% of patients. Patients with eyelid laceration, extra-ocular motion (EOM) abnormality, and pupillary defect were more likely to have a change in management. There was no delay of surgical bony fracture management. Conclusion: In patients with midface trauma including orbital wall fractures those with eyelid laceration, EOM abnormality, and pupillary defect were likely to undergo ocular management change as a result of ophthalmology consultation.

Metastatic Merkel cell carcinoma presenting as an orbital mass.

A 67-year-old female presented with 2 weeks of right eye pain, redness, and diplopia. An orbital mass was found on magnetic resonance imaging (MRI), and biopsy revealed Merkel cell carcinoma (MCC). She had no primary head or neck lesion and no previous history of MCC. Positron emission tomography (PET) scan showed hypermetabolic subcutaneous lesions of the lower extremity andmultiple osseous lesions of the axial and appendicular skeleton. She received palliative external radiation of 20 Gy in 5 fractions to the orbit. After discussing immunotherapy, she opted for comfort care and expired 1 month later. To the best of our knowledge, this is only the third case of MCC with distant metastasis to the orbit and the first case in which the patient had no previous diagnosis of MCC and no known primary tumor.

Orbital Complications of Acute Sinusitis in Pediatric Patients: Management of Chandler III Patients.

Background: Surgery is often avoided in the setting of pediatric orbital complications from acute sinusitis unless necessitated by alarming ophthalmological signs. Criteria for surgical intervention are not well-defined. Objective: We aim to review our experiences, management practices and patient outcomes over a ten-year period for Chandler III patients. Methods: A retrospective review was performed from January 1, 2007 through December 31, 2016 of patients treated for orbital symptoms secondary to acute sinusitis at a free-standing tertiary-care pediatric hospital. Results: Of the 186 patients reviewed, 42 Chandler III patients were included. Average age was 82.6 months (SD 50.6) with a slight male predominance (M to F, 1.8 to 1). 27 patients (64.3%) underwent intervention including endoscopic sinus surgery (ESS) with or without orbitotomy. Late surgical intervention (>48hrs from admission) demonstrated significant increase in overall length of stay (LOS) when compared with early surgical intervention and/or medical management (median, 6.9 vs 3.6 vs 3.7 days; p < 0.01). Postoperative LOS was also higher in the late surgery group compared with patients who had surgery within 48 hours of admission, but this did not reach statistical significance [median, 3.8 vs 2.8 days, p= 0.12]. There was no significant difference in overall abscess volume between patients who underwent intervention and those who did not (1019 mm3 vs 805 mm3, p = 0.5), but abscess width ≥ 1.2 cm was associated with higher rates of intervention. An alarming extraocular exam was the most common factor associated with surgical intervention. Conclusion: Pediatric subperiosteal orbital abscess may prompt surgical intervention by ESS. An alarming ophthalmologic exam should prompt consideration of early intervention, which may lead to decreased overall and post-operative length of hospital stay. Level of Evidence: 4.

Recurrent Retrobulbar Hemorrhage Associated With CPAP Use After Orbital Fracture Repair.

We present a patient who underwent orbital fracture repair complicated by retrobulbar hemorrhages twice within the first postoperative week. The suspected cause is continuous positive airway pressure (CPAP) use with inappropriate patient-modified settings. The most likely mechanism of action was venous congestion from the extrinsic positive pressure, similar to Valsalva maneuvers increasing orbital vasculature pressure. In our patient, because his orbital blood vessels had recently been cauterized, they were too fragile to handle the engorgement and bled, leading to a retrobulbar hemorrhage. It is possible that at a lower CPAP setting, the vascular congestion would not have been as severe and caused bleeding. We recommend routinely asking patients about CPAP use before orbital surgeries and instructing patients to stop CPAP usage for 1 week after any orbital surgeries if medically cleared.

Ophthalmic complications associated with methamphetamine use disorder.

Purpose: To describe the devastating ophthalmic sequelae of methamphetamine use disorder in two patients who developed vision loss from ocular complications, including keratitis and endophthalmitis. Observations: Case 1 is a 26-year-old male with hepatitis C, poorly controlled type 1 diabetes, and chronic methamphetamine use who presented with a corneal ulcer in the left eye. Corneal culture grew Staphylococcus aureus and Streptococcus viridans, prompting antibiotic therapy. Follow-up exam showed peripheral corneal ulceration OD and diffusely vascularized and scarred cornea OS, although nonadherence was reported. Vision eventually worsened to hand motions OD and light perception OS.Case 2 is a 44-year-old woman with hepatitis C, acute myeloid leukemia, dry eye syndrome secondary to chronic graft-versus-host disease (GVHD), and chronic methamphetamine use who presented with a diffuse corneal infiltrate and hypopyon. She underwent emergent corneal transplantation, vitrectomy, and broad-spectrum intravitreal and intravenous antibiotics. Vitreous cultures were positive for Streptococcus pyogenes. However, progressive disease eventually required enucleation despite initial globe salvaging measures. Conclusions and importance: These two patient cases highlight the risk of vision loss or blindness due to the detrimental effects of chronic methamphetamine use on the eye, including the potential for keratitis and endophthalmitis. Given the increasing prevalence of methamphetamine use disorder in the United States, further understanding of these toxicities and preventive strategies are needed.

The clinical presentation and magnetic resonance imaging characteristics of an infant with idiopathic orbital inflammation.

Idiopathic orbital inflammation is rare in the pediatric population, particularly infants. It can be mistaken either for orbital infection or malignant tumors. We report the case of a 9-month-old previously healthy white boy who presented with right upper eyelid swelling. Magnetic resonance imaging revealed an abnormal T2-hypointense enhancing lesion within the extraconal superior right orbit.

Relationship between ocular dominance and brow position in patients with blepharoptosis.

PURPOSE: This study aims to determine if ocular dominance plays a role in predicting compensatory eyebrow elevation in cases of ptosis. METHODS: This retrospective observational cohort study screened all individuals presenting to two tertiary oculoplastics practices with complaints of ptosis for entry. Primary position photographs were obtained. Ocular dominance was assessed via a modified Porta test. Ptosis was defined in bilateral cases as marginal reflex distance of <2.5 mm in both eyes and in unilateral cases as either an MRD1 < 2.5 mm or MRD1 of >1 mm lower on one side. Asymmetry in brow height was defined as a difference of >1 mm. Chi square and t-tests were performed. RESULTS: Sixty-eight patients from the both tertiary practices met inclusion criteria (37 male, 31 female). Concordance between the higher brow and the dominant side was 50.0% (n = 22, p > 0.05). Mean brow height on the dominant side (15.5 mm) was not statistically different than brow height on the non-dominant side (15.3 mm, p > 0.05). The concordance between the higher brow and the lower MRD1 eyelid was not significant (45.5%, n = 20, p > 0.05). The difference in mean brow height between the lower and higher MRD1 eyes was not significantly different (-0.11 mm; p > 0.05). This also held true when restricted to unilateral cases (0.28; p > 0.05). CONCLUSIONS: Although asymmetric brow elevation can be noted in patients with ptosis, ocular dominance does not appear to be concordant with this asymmetry. Additionally, brow height does not appear to be concordant with MRD1 in cases of ptosis.

Orbital rhabdomyosarcoma in a child with Leigh syndrome.

Anatomical Description of Zygomatic Foramina in African American Skulls.

PURPOSE: The zygomaticofacial/temporal/orbital nerve is a terminal branch of the zygomatic nerve and exits the orbit through zygomatic foramina. The nomenclature in the literature varies with some studies identifying all 3 foramina on the malar surface of the zygoma, while others describe each along different aspects of the zygoma. In this study, foramen on the malar surface of the zygoma is termed zygomatic foramen, and the authors describe anatomical variations in the position and number of these foramina in an African American population. METHODS: Sixty-two African American skulls from the Hamann-Todd collection of the Cleveland Museum of Natural History were studied. The primary outcome was the number of zygomatic foramina on the malar surface of the zygomatic bone. Secondary outcomes included the location of foramina relative to the orbital rim and the frontozygomatic suture. Mean and standard deviation were used to describe measurements. Chi-squared and Wilcoxon signed rank tests were used to analyze measurements between left and right hemicrania. RESULTS: The average number of foramina was 1.98 ± 0.93. More foramina were found on the right (2.13 ± 0.98) when compared with the left (1.68 ± 0.79; p = 0.001). The average distance between the lateral-most and medial-most foramina was 9.7 ± 5.0 mm. The distance from the orbital rim to the lateral foramen was 8.4 ± 4.2 mm, and distance from the orbital rim to the medial foramen was 7.7 ± 2.1 mm. The frontozygomatic suture was 22.9 ± 3.9 mm from the lateral foramen and 27.9 ± 3.6 mm from the medial foramen. CONCLUSION: The locations of the foramina in relation to the frontozygomatic suture and orbital rim were consistent with other populations. However, in this African American population, more zygomatic foramina were noted compared with previously published results in Korean, Indian, Brazilian, and West Anatolian populations. Surgeons should be cognizant of zygomatic foramina in this population to reduce potential neurovascular complications.

Recurrent Orbital Solitary Fibrous Tumor in a 12-Year-Old.

PURPOSE: To report the clinical features and pathology of orbital solitary fibrous tumors and present a case of a recurrence in a 12-year-old boy. METHODS: Case Report. RESULTS: A 12-year-old boy presented to our institution with double vision in upgaze for 6 months. Examination revealed 3 mm of left-sided proptosis, hypoglobus, and -3 impairment of supraduction. Magnetic resonance imaging of the orbits showed an avidly enhancing mass within the superolateral aspect of the orbit. Biopsy revealed a solitary fibrous tumor with STAT6 and CD34 positivity. Positron emission tomography-computed tomography was negative for metastatic disease. The tumor underwent excision. However, 4 months postoperatively, imaging revealed changes consistent with recurrence. A repeat lateral orbitotomy with orbital rim marginotomy was performed with complete gross excision of the tumor. The patient remains tumor-free 22 months after reoperation. CONCLUSION: Orbital solitary fibrous tumor rarely occurs in the pediatric population. Despite initial complete gross tumor excision, this case represents the youngest individual with a recurrence to the authors' knowledge. This case of rapid recurrence may have been due to tumor seeding at the time of initial biopsy or other factors. This case increases the known spectrum of orbital solitary fibrous tumors.

Dysthyroid optic neuropathy: update on pathogenesis, diagnosis, and management.

INTRODUCTION: Dysthyroid optic neuropathy (DON) is a severe manifestation of thyroid eye disease (TED) that can result in permanent vision loss. Management is complex, multidisciplinary, and involves medical and/or surgical therapies. This review describes current concepts in the epidemiology, pathophysiology, diagnosis, and treatment of DON. AREAS COVERED: An extensive review of the literature was performed to detail current concepts on the diagnosis and management of DON. This includes utilization of various medical and surgical modalities for disease management. EXPERT COMMENTARY: DON can result in permanent blindness and often requires the use of corticosteroids and surgical decompression. We favor the use of intravenous corticosteroids and a transcaruncular approach when surgical decompression is indicated. The use of orbital radiation for DON is often reserved for patients that are poor surgical candidates and/or patients with refractory disease.

Comparison of the FaroArm Laser Scanner With the MicroScribe Digitizer Using Basicranial Measurements.

PURPOSE: To compare the results of a mechanical 3-dimensional laser scanner for craniofacial measurements of the basicranium to a validated coordinate device. METHODS: Access was granted by the Cleveland Natural History Museum to evaluate the Hamann-Todd Human Osteological Collection for this study. The MicroScribe and the FaroArm were used to gather coordinate data of various bony landmarks measurements including the prosthion, staphylion, hormion, and basion. Seventy-three human skulls were measured and scanned. Distances calculated from the coordinates were tested for agreement using the Bland-Altman test. RESULTS: There were no significant differences in the bias or slope measures between the MicroScribe and the FaroArm. In addition to the univariate test for slope significance, multivariable analysis using age, gender, and race as additional predictors showed no significant difference in any variable (P < 0.05). CONCLUSION: This is the first study demonstrating agreement of the FaroArm in any human skull measurement with the validated MicroScribe digitizer. Compared with the MicroScribe digitizer, the FaroArm allows for 3-dimensional imaging and the ability to store, handle, and view data digitally. Future use of real-time facial measurements using the FaroArm offers potential for improved surgical planning and outcomes.

Corneal Toxicity Associated With Aquarium Coral Palytoxin.

PURPOSE: To report a series of patients who developed corneal toxicity after exposure to aquarium coral palytoxin. DESIGN: Multicenter retrospective case series. METHODS: Retrospective review. RESULTS: Seven patients presented with corneal findings ranging from superficial punctate epitheliopathy to bilateral corneal melt with subsequent perforation. Among those with mild corneal findings, resolution was achieved with topical steroids and lubrication, whereas some patients who developed progressive corneal melt required therapeutic penetrating keratoplasty. The history in all patients revealed exposure to aquarium zoanthid corals shortly before disease onset. A review of the literature revealed that there are few prior reports of coral-associated corneal toxicity and that some species of coral secrete a substance known as palytoxin, a potent vasoconstrictor that inhibits the membranous sodium-potassium ATPase pump across cell types and can cause rapid death if inhaled or ingested. CONCLUSIONS: This is the largest case series to date demonstrating patients with aquarium coral palytoxin-associated corneal toxicity, and is the first to provide details of related histopathologic findings. Similar to other forms of toxic keratoconjunctivitis, a detailed history and careful clinical assessment are required, as well as timely removal of the offending agent from the patients' ocular milieu and environment. Mild ocular surface and corneal disease may be treated effectively with aggressive topical steroid therapy and lubrication. Given the potential severity of ocular as well as systemic adverse effects, there should be increased awareness of this entity among eye care professionals, aquarium enthusiasts, and the general public.

Online Ratings of ASOPRS Surgeons: What Do Your Patients Really Think of You?

PURPOSE: To characterize patient evaluations of American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) surgeons on a popular online physician rating website in an effort to determine which factors play a role in determining the likelihood of a patient recommending an ASOPRS surgeon to family and friends. METHODS: After obtaining approval and access from Healthgrades.com, the website database was searched for 612 U.S.-based ASOPRS members using their name as published on http://www.asoprs.org/ as of May 2015. For each surgeon, the total number of ratings and average ratings were recorded under each category. The evaluator recommendation, defined as the response to the questions of "likelihood of recommending Dr. X to family and friends," constituted the main outcome measure. Variables from each surgeon were compared using unpaired t tests, with statistical significance set at p < 0.05. Correlations were analyzed using Spearman correlation (rs), with coefficients of greater than or equal to 0.40 or less than or equal to -0.40 considered significant. RESULTS: Five-hundred nineteen members (85%) had at least 1 rating while 222 members (36%) had 10 or more ratings. The mean number of ratings for all rated members was 11.4 (range, 1-77; standard deviation [SD] = 11.1) and mean evaluator recommendation score was 4.16 (range, 1-5; SD = 0.79). There was a strong negative correlation between total wait time and evaluator recommendation score (rs = -0.409, p < 0.001). The average number of ratings and rating scores for all categories were not significantly different when comparing male with female members. University-employed members had significantly fewer ratings (8.46; range, 1-52; SD = 9.3) compared with other members (11.9; range, 1-77; SD = 11.3) (p < 0.016). There were no differences in any other rating score when comparing those university-employed members with other members. CONCLUSION: Online patient-reported evaluations of ASOPRS surgeons appear high in many categories. Long wait times correlate strongly with lower recommendation scores. Further study is required to determine how online patient reviews correlate to objective outcome measures, and how these reviews affect surgeon selection by patients.
