Orbital Compartment Syndrome in Severe Burns: Predictive Factors, Timing, and Complications of Intervention.

PURPOSE: Severe burn patients require high-volume fluid resuscitation, which increases risk for orbital compartment syndrome (OCS). We aimed to understand surgeons' practice patterns and to examine risk factors for OCS, timing of lateral canthotomy and cantholysis (LCC), and complications of intervention. METHODS: A survey of American Society of Ophthalmic Plastic and Reconstructive Surgery and North American Society of Academic Orbital Surgeons' practice patterns in burn patients was undertaken. In addition, a retrospective analysis was conducted of 107 patients with burns greater than 20% total body surface area at 1 institution from January 1, 2009, to June 1, 2018. Patients with Stevens-Johnson Syndrome or Toxic Epidermal Necrolysis, frostbite, or no ophthalmologic consultation were excluded. Risk factors for OCS, timing of LCC, and complications of the intervention were examined. RESULTS: In the survey, 37 of 54 respondents had treated burn patients, of which 29 followed no protocol. Threshold intraocular pressure for intervention varied widely, and nearly all reported having seen complications from LCC in burn patients. For the retrospective analysis, 107 patients met criteria, of which 22 (20.6%) required LCC. Renal failure, inhalation injury, eyelid burns, higher total body surface area, elevated lactate, increased number of escharotomies, and greater total fluid required were significantly associated with the clinical decision that the patient was at risk for OCS requiring LCC. Fluid resuscitation in excess of the Ivy Index (250 ml/kg) increased odds of LCC 8.6 times. Average time of LCC was 15.8 hours after burn. LCC patients experienced higher rates of complications including eyelid retraction, exposure keratopathy, and corneal ulceration. CONCLUSIONS: Severe burn patients should be monitored closely by an ophthalmologist during the first 48 hours for signs of OCS. Further studies should aim to recommend protocols guiding evaluation and intervention.

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.

Increased Incidence of Rhino-Orbital-Cerebral Mucormycosis After Colorado Flooding.

In September 2013, central Colorado experienced a record amount of rainfall resulting in widespread flooding. Within 1 month of the flooding, 4 patients presented to the authors' institution with rhino-orbital-cerebral mucormycosis. This represents the largest number of cases ever recorded over a 1-month period. The authors hypothesize that the combination of immunocompromised status and environmental exposure resulted in the increased incidence.

Sphenoid Wing Meningioma With Extraocular Muscle Involvement Mimicking Idiopathic Orbital Inflammation.

Meningiomas are slow growing, typically benign, tumors originating from arachnoid cap cells. Specifically, sphenoid wing or spheno-orbital meningiomas infiltrate the lesser wing of the sphenoid, lateral orbital wall, and orbital roof with occasional extension to the superior orbital fissure, optic canal, anterior clinoid process, and middle cranial fossa where neurologic and ophthalmologic functions are impaired by compressive injury. The extraocular muscles are rarely involved. The authors present a rare case of an spheno-orbital meningioma causing extraocular muscle enlargement mimicking idiopathic orbital inflammation and highlight important diagnostic clues to meningioma.

C-Reactive Protein As a Marker for Initiating Steroid Treatment in Children With Orbital Cellulitis.

PURPOSE: To determine both the benefit of systemic steroids in pediatric patients with orbital cellulitis and to assess the usefulness of C-reactive protein (CRP) levels as a marker for starting steroids. METHODS: Prospective, comparative interventional study. Pediatric patients aged 1 to 18 years admitted to a tertiary care children's hospital with a diagnosis of orbital cellulitis from October 2012 to March 2014 were included in the study. All patients were treated with intravenous antibiotics, and patients with subperiosteal abscess who met previously published criteria for surgical decompression underwent combined transorbital drainage and/or endoscopic sinus surgery. CRP was measured daily as a biomarker of inflammation, and when below 4 mg/dl, patients were started on oral prednisone 1 mg/kg per day for 7 days. Patients whose families did not consent to steroid treatment served as the control group. Patients were followed after discharge until symptoms resolved and all medications were discontinued. RESULTS: Thirty-one children were diagnosed with orbital cellulitis during the study period. Of these 31 children, 24 received oral steroids (77%) and 7 did not (23%). There were 19 males and 5 females in the steroid group with an average age of 8.1 years, and 6 males and 1 female in the nonsteroid group with an average age of 7.1 years (p = 0.618). Thirteen patients (54%) in the steroid group and 2 patients (29%) in the nonsteroid group underwent sinus surgery with or without orbitotomy (p = 0.394). The average CRP at the onset of steroid treatment was 2.8 mg/dl (range: 0.5-4). Patients who received oral steroids were admitted for an average of 3.96 days. In comparison, patients who did not receive steroids were admitted for an average of 7.17 days (p < 0.05). Once CRP was ≤4 mg/dl, patients treated with steroids remained in the hospital for another 1.1 days, while patients who did not receive steroids remained hospitalized for another 4.9 days (p < 0.01). In the steroid group, 2 families reported increased hyperactivity in their children while on steroids. There was 1 case in each group of recurrence of symptoms after discharge from the hospital. Average follow-up time was 2.4 months in the steroid group and 2 months in the nonsteroid group (p = 0.996). At last visit, all patients returned to their baseline ophthalmic examination. There were no cases of vision loss or permanent ocular disability in either group. CONCLUSIONS: Our results give further evidence of the safety and benefit of systemic steroids in children with orbital cellulitis. Futhermore, this is the first study to suggest a standardized starting point (CRP ≤ 4 mg/dl) and dosing schedule (oral prednisone 1 mg/kg for 7 days) for children with orbital cellulitis. Patients who received systemic steroids after CRP dropped below 4 mg/dl were discharged from the hospital earlier than patients who did not receive systemic steroids.

Perioperative pregabalin for attenuation of postoperative pain after eyelid surgery.

PURPOSE: To examine the effect of a 1-time dose of pregabalin (Lyrica) on the perception of pain and analgesic consumption after oculofacial plastic surgery. METHODS: In this prospective, randomized, double-blind, placebo-controlled trial, patients presenting to the oculofacial plastic surgery service at University of Colorado Eye Center for functional eyelid surgery and who met the study criteria were consecutively enrolled between October 2011 and September 2012. Subjects were randomized to either placebo or 150 mg pregabalin administered 15 minutes to an hour prior to the procedure. The procedure was then performed under the usual standard of care. Postoperatively, study subjects recorded pain scores on visual analog scales (range 0-100) at 1 to 2 hours, 2 to 4 hours, 8 to 12 hours, 20 to 28 hours, and 36 to 48 hours and the amount of acetaminophen consumed. Data were analyzed with Statistical Analysis System software using mixed-effects linear models. RESULTS: Fifty-two patients were enrolled. Three patients were excluded due to incomplete follow up (n = 2) and postoperative course requiring early unblinding (n = 1). Twenty-six subjects were men. Average age was 68 years (range, 25-89). Eyelid procedures performed included blepharoplasty (18), canthoplasty (11), ptosis repair (15), eyelid retraction repair (2), pentagonal wedge resection (1), and MOHS reconstruction (2). Twenty-six patients were randomized to receive pregabalin, while the remainder received placebo. There was no significant difference in demographics between the 2 groups. The pregabalin group reported pain scores that were 5.5 points lower on average compared with the placebo group (p = 0.0307). Patients in the pregabalin group also consumed half as much acetaminophen (1.3 g) on average as the placebo group (2.6 g) during the postoperative period. CONCLUSIONS: Pregabalin is effective in reducing postoperative pain after oculoplastic procedures when compared with placebo. It may be a useful adjunct for pain control in selected patients.

Tear Trough Incision for External Dacryocystorhinostomy.

PURPOSE: Scar formation is a frequently cited complication of external dacryocystorhinostomy (exDCR). The purpose of this study is to evaluate scar appearance after exDCR with the skin incision placed in the tear trough. METHODS: Multicenter, prospective, noncomparative interventional study was approved by the University of Colorado Institutional Review Board. Patients undergoing exDCR from February 2013 to January 2014 were included in the study, and surgeries were performed by all authors. The incision site for all patients started just under the medial canthal tendon and extended inferolaterally into the tear trough for 10 mm to 15 mm. External dacryocystorhinostomy was performed in the usual manner, and the incision was closed according to the surgeon's preference. At 3 months postop, all patients were asked to rate their scar on the basis of the following grading scale: 0, invisible incision; 1, minimally visible incision; 2, moderately visible incision; and 3, very visible incision. Functional success of the surgery was also determined by asking the patients if their symptoms resolved, improved, or did not change. External photographs taken at 3 months after surgery were graded by 3 independent oculofacial and facial plastic surgeons using the same grading scale. RESULTS: Seventy-two surgeries were performed in 68 consecutive exDCR patients with nasolacrimal duct obstruction during the study period. Sixty-nine out of 72 patients reported improved or resolved symptoms (95.8%). The average patient scar grade was 0.21, while the average surgeon scar grade was 0.99 (p < 0.001). Sixty out of the 72 patients graded the scar as invisible (83.3%), and only 3 patients graded the scar as moderately visible (4.2%). No patients graded the scar as very visible. Of the 216 surgeon grades, 55 scars were graded as invisible (25.5%), while 8 were graded as very visible (3.7%). CONCLUSIONS: Scar appearance after exDCR with the incision placed in the tear trough is minimally visible to surgeons, and more importantly, nearly invisible to patients.

Biodegradable Fixation of the Orbital Rim After Lateral Orbitotomy.

PURPOSE: To describe authors' experience with repair of the lateral orbital rim with poly-L/DL-lactic acid (PDLLA) biodegradable plates using ultrasonic pin fixation after lateral orbitotomy with bone flap. METHODS: The authors retrospectively reviewed all patients who underwent a lateral orbitotomy with bone flap for biopsy of orbital tumors at their institution from January 2010 to May 2013. All patients underwent an orbitotomy by either a lateral eyelid crease incision or lateral canthotomy/cantholysis approach. A lateral bone flap was fashioned in the usual manner, extending from the frontozygomatic suture down the lateral rim for approximately 2 cm. The bone flap was repaired in each case with either a 6 or 7 hole PDLLA plate and secured with ultrasonic PDLLA pin fixation. RESULTS: Twenty-four patients were identified who underwent a lateral orbitotomy with bone flap. Of these patients, 10 were repaired with PDLLA plates. The average age of the patients with PDLLA bone flap fixation was 55 years (range 5-85). The average follow-up time was 12.9 months (range 4-42). Indications included 4 lacrimal gland tumors, 4 intraconal tumors, and 2 lateral orbital tumors. Final diagnosis included lymphoma (3), squamous cell carcinoma (1), neuroblastoma (1), amyloid (1), fibrous tissue (1), sarcoidosis (1), cavernous hemangioma (1), and idiopathic orbital inflammation (1). Three patients had edema of the surrounding soft tissues after surgery, all but 1 resolved by postop month 3. There were 2 cases of transient temporal numbness that resolved by postop month 1. There were no cases of vision loss, extraocular motility deficit, infection, or need for removal of the implant before absorption. CONCLUSIONS: PDLLA biodegradable plates with ultrasonic pin placement provide a safe, effective means for lateral rim fixation after orbitotomy with bone flap.

Clinical features and treatment of pediatric orbit fractures.

PURPOSE: To describe a series of orbital fractures and associated ophthalmic and craniofacial injuries in the pediatric population. METHODS: A retrospective case series of 312 pediatric patients over a 9-year period (2002-2011) with orbit fractures diagnosed by CT. RESULTS: Five hundred ninety-one fractures in 312 patients were evaluated. There were 192 boys (62%) and 120 girls (38%) with an average age of 7.3 years (range 4 months to 16 years). Orbit fractures associated with other craniofacial fractures were more common (62%) than isolated orbit fractures (internal fractures and fractures involving the orbital rim but without extension beyond the orbit) (38%). Roof and medial wall fractures were most common (30% and 28%, respectively), followed by orbital floor (24%) and lateral wall (18%) fractures. Orbital roof fractures are the most common fracture in patients <8 years old, whereas orbital floor fractures are the most common fracture in patients older than 8 years. Eighty-seven patients (28%) underwent surgical repair. There is an increasing incidence of surgery in older patients (p = 0.02). Associated neurologic injuries were more common (23%) than associated ophthalmic injuries (20%). CONCLUSIONS: Pediatric orbit fracture patterns are dictated by the age of the patient with respect to their craniofacial morphology and mechanism of injury. Orbital roof fractures are more likely to occur in younger patients and not require surgery, whereas orbital floor fractures are more common in older patients and are more likely to require surgery.

Orbital invasion by ACTH-secreting pituitary adenomas.

Orbital invasion by pituitary tumors is rare. To the best of the authors' knowledge, adrenocorticotrophin (ACTH)-secreting pituitary tumors with orbital invasion have not been described in MEDLINE indexed literature. The authors report 2 cases of ACTH-secreting tumors with orbital invasion. One patient had a history of endoscopic transsphenoidal subtotal resection of an ACTH-secreting tumor and presented with recurrence in the orbit. The second patient had a long history of visual loss considered to be secondary to glaucoma. Neuroimaging revealed a destructive mass involving the sella turcica with extension in the right orbit. Debulking of the mass was performed via a transsphenoidal approach, and histopathology revealed an ACTH-secreting adenoma. ACTH-secreting adenoma should be considered in the differential of tumors involving the sella turcica with orbital invasion.

Pediatric facial fractures from dog bites.

PURPOSE: To report a series of pediatric facial fractures associated with dog bites. METHODS: Retrospective review of all dog bite injuries to the face with facial fractures in children from January 1, 2003, to October 31, 2011, at Children's Hospital Colorado (Aurora, Colorado). Patient demographics, location and number of fractures, clinical course, surgical repair, and complications were recorded and analyzed using Excel statistical software. RESULTS: Seventeen of 1,201 (1.4%) children with dog bite injuries to the face also sustained facial fractures. The average age of patients was 3.9 ± 3.2 years and 53% were female. Thirty-five percent of patients presented with multiple facial fractures. The most common fracture involved the nasal bone (29%), while the remainder sustained fractures of the zygomatic arch, orbital rim, orbital floor, skull, mandible, maxilla, and/or sinuses. Of the 17 patients, 41% also sustained eyelid lacerations, 24% had injuries to the facial nerve, and 18% had canalicular lacerations. Fourteen of the 17 patients required surgical repair under general anesthesia. CONCLUSIONS: Although uncommon, facial fractures associated with dog bites are a significant source of morbidity, often requiring complex surgical repair. Severe injuries to the face from dog bites should be evaluated for possible fractures in addition to soft tissue injuries.

Bilateral Candida and atypical mycobacterial infection after frontalis sling suspension with silicone rod to correct congenital ptosis.

In this case report, the authors describe an unusual complication of a frontalis sling suspension with silicone rods. A 5-year-old girl with blepharophimosis syndrome underwent frontalis sling suspension using an open sky technique. Four weeks after surgery, she was noted to have pustules over both upper eyelids and eyebrows. Cultures from the surgical sites grew Mycobacterium chelonae and Candida parapsilosis. Intravenous antibiotics and antifungals and sling explantation were curative. One month after sling explantation, the patient maintained an adequate marginal reflex distance 1. Atypical mycobacterial and Candida infection should be considered in the differential diagnoses of postoperative infection after frontalis sling suspension with silicone rods.

American Society of Ophthalmic Plastic and Reconstructive Surgery fellowship survey: fellows selection criteria for training programs.

PURPOSE: To investigate the characteristics that American Society of Ophthalmic Plastic and Reconstructive Surgery fellows seek in fellowship training programs. METHODS: A 14-question anonymous SurveyMonkey survey was created for the 2011 to 2014 American Society of Ophthalmic Plastic and Reconstructive Surgery graduates. The survey evaluated fellow demographics, the interview process, and qualities fellows seek in fellowship training programs. A Likert scale was used to rate different qualities (1: not important, 9: very important), and summary statistics are reported as overall means and standard deviations. Analysis of variance comparisons were made between the different Ophthalmic Plastic and Reconstructive Surgery fellow graduate years, gender, and future practice goals. RESULTS: In total, 87 surveys were e-mailed with 67 responses, a 77% response rate. The qualities with the highest mean were variety of surgical procedures (mean ± standard deviation: 8.6 ± 0.7), volume of procedures/surgeries (8.6 ± 0.7), personality of the program director (8.2 ± 1.3), and interview (7.7 ± 1.4). The characteristics that ranked the lowest in descending order were presence of a county hospital (5.1 ± 2.2), proximity to family (4.8 ± 2.7), didactics (4.7 ± 1.9), and benefits (4.4 ± 2.0). There was no statistically significant difference when comparing the groups according to gender and year of graduation. Fellows who want to pursue a career in academic medicine ranked academic fellowships higher in importance (8.0 ± 1.0) than those who wanted a career in private practice (5.3 ± 2.2). CONCLUSIONS: American Society of Ophthalmic Plastic and Reconstructive Surgery fellows place an emphasis on surgical experience, the program director's personality, and the interview process when ranking fellowship training programs. This information is valuable for program directors to better recruit fellows.

Orbital Venous Malformation Excision after Transcaruncular Embolization with Onyx.

Orbital venous malformations are low-flow lesions resulting from vascular dysgenesis during development. Patients may present with vision loss, proptosis accentuated by Valsalva, and/or painful spontaneous thrombosis. The preferred treatment for symptomatic lesions is embolization combined with excision. A 34-year-old male presented to our institution from an outside emergency department with a diagnosis of presumed idiopathic orbital inflammation. For the prior month, he had been experiencing left orbital pressure, subjective eye bulging, and both diplopia and blurry vision when in peripheral gaze or when bending over. Despite initial improvement with steroids, his symptoms recurred with tapering. Visual acuity was reduced to 20/25, but pupils and motility remained normal. Biopsy demonstrated a vascular lesion characterized by fibroadipose tissue with histologically unremarkable blood vessels, and cerebral arteriography showed no high-flow components. A diagnosis of orbital venous malformation was made. He then underwent intraoperative angiography and Onyx embolization followed by excision via a transcaruncular approach. Two prior reports have described the use of Onyx in venolymphatic malformations. This report highlights a detailed approach to defining flow characteristics pre- and intraoperatively and expands upon our understanding of the use of Onyx for such cases.

Comparison of free tarsoconjunctival grafts and Hughes tarsoconjunctival grafts for lower eyelid reconstruction.

PURPOSE: To review the use of free autogenous tarsoconjunctival (TC) grafts and Hughes TC flaps in the practice of one of the authors (MJH) and compare complications and outcomes and develop a rationale for the selection of surgical technique. METHODS: Retrospective comparative case series of 70 patients who underwent reconstructive surgery for a major full-thickness lower eyelid defect using a free autogenous TC graft or Hughes TC pedicle flap by one of the authors (MJH). Rates of complications, including erythema of the eyelid margin, eyelid position abnormalities, and need for additional surgeries, were reviewed. RESULTS: During a 15-year period, 70 patients with full-thickness lower eyelid defects were treated with autogenous TC grafts and flaps. The average age of the patients receiving a free TC graft was younger than the average age of patients receiving a Hughes TC graft (63 versus 73 years, p < 0.001). Patients with a free TC graft were more likely to have a smaller eyelid defect than the patients receiving a Hughes TC graft (52% versus 72%, p < 0.001). Patients receiving a free TC graft were less likely to require surgery to repair eyelid margin erythema than those in receiving a Hughes TC flap (one patient [2%] versus 5 patients [19%], respectively [odds ratio = 0.10, confidence interval = 0.01 to 0.95]). The average follow up was 22 months. CONCLUSIONS: Free TC flaps associated with mycocutaneous advancement flaps are less likely to lead to complications of eyelid margin erythema and subsequent revision surgery than Hughes TC flaps with full-thickness skin grafts.

Rapid onset proptosis and vision loss as the initial presentation of Burkitt lymphoma.

Burkitt lymphoma is a rapidly growing, high-grade non-Hodgkin lymphoma occurring in three distinct clinical subtypes: endemic, sporadic, and human immunodeficiency associated. The sporadic subtype typically presents as an abdominal mass. Orbital involvement has rarely been reported. The authors report a case of Burkitt lymphoma presenting as rapidly progressive proptosis and loss of vision. Given the tumor's rapid growth rate, potential for vision loss, and good response to chemotherapy, clinicians should be aware of this rare presentation.

Ocular Kaposi Sarcoma Associated With Systemic Disease and Complete Resolution After Medical Therapy.

This case report describes a man with untreated HIV infection who presented with Kaposi sarcoma caruncular lesions that resolved completely with medical treatment.

Amniotic membrane transplants in the pediatric population.

PURPOSE: To investigate the indications for and results of amniotic membrane transplantation (AMT) for the treatment of ocular disease in pediatric patients at a single institution. METHODS: The medical records of patients <18 years of age who underwent AMT for ocular disease between January 1, 2003, and September 1, 2015, were reviewed retrospectively. Patients were determined to have reached a clinical endpoint if there was resolution of the ocular condition being treated after AMT placement, no additional surgery required for treatment of the ocular condition, and no active disease at most recent follow-up. RESULTS: A total of 48 records were reviewed. Of these, 32 patients (67%) received AMT for treatment of ocular disease related to Stevens Johnson syndrome (SJS), 29 (94%) of whom reached the clinical endpoint. The remaining 16 patients (33%) underwent AMT for indications other than SJS, including difficult-to-treat corneal epithelial defects and ulcers, conjunctival reconstruction, and scarring after strabismus surgery. Of these, 80% reached the clinical endpoint. There were no adverse effects related to AMT in either group. CONCLUSIONS: In our series, AMT was used successfully and without complications.

Endoscopic Management of Paranasal Sinus Mucoceles: Meta-analysis of Visual Outcomes.

Objective Paranasal sinus mucoceles are benign cystic lesions originating from sinus mucosa that can impinge on adjacent orbital structures, causing ophthalmic sequelae such as decreased visual acuity. Definitive treatment requires surgery. We present the first meta-analysis quantifying the effect of preoperative visual function and time to surgery on postoperative visual acuity outcomes. Data Sources PubMed, Ovid, Embase, Web of Science, and the Cochrane Library. Methods Two independent authors systematically reviewed articles describing outcomes after endoscopic sinus surgery for paranasal sinus mucoceles presenting with visual loss. Available data from case reports and series were combined to analyze the associations among preoperative visual acuity, time to surgery, and postoperative outcomes. Results Eighty-five studies were included that provided data on 207 patients. The average presenting visual acuity was 1.57 logMAR (logarithm of the minimum angle of resolution), and the average postoperative visual acuity was 0.21 logMAR, with visual improvement in 71.5% of cases. Preoperative visual acuity ≥1.52 logMAR correlated with postoperative improvement >1 logMAR ( R = 0.4887, P < .0001). A correlation was found between a time to surgery <6 days and postoperative improvement ( R = 0.297, P < .0001). Receiver operator curve analysis of these thresholds demonstrated a moderately accurate prognostic ability (area under the curve: 75.1 for preoperative visual acuity and 73.1 for time to surgery). Conclusion Visual loss resulting from paranasal sinus mucoceles is potentially reversible in most cases, even those presenting with poor vision. When possible, surgery should be performed promptly after diagnosis, but emergency surgery does not appear to be necessary for vision restoration.

Ophthalmic manifestations and outcomes after cavernous sinus thrombosis in children.

PURPOSE: To review the causes, treatment, and outcomes of cavernous sinus thrombosis (CST) in children. METHODS: The medical records of children (<18 years of age) diagnosed with thrombophlebitis of an intracranial venous sinus were reviewed to identify cases of CST presenting to Children's Hospital Colorado from January 2000 through January 2013. Cases were evaluated for etiology, symptoms, imaging characteristics, treatment, and outcomes. RESULTS: A total of 110 children with a venous thrombus of an intracranial sinus were included. Of these, 9 had a CST. All cases were confirmed by magnetic resonance imaging. All 9 had sinusitis, 4 had orbital involvement, and 1 resulted from a nasal septal abscess. Eight cases presented with ophthalmoplegia, and 5 presented with decreased vision. Every patient underwent sinus surgery: 4 underwent orbitotomy for abscess drainage, and 1 required bilateral exenteration. Cultures were inconclusive in 2 cases, and 2 cases were culture positive rhino-orbital mucormycosis. There was 1 case of methicillin-resistant Staphylococcus aureus. Of the 9 cases, 4 returned to normal vision and ocular motility; 5 had permanent ophthalmoplegia and vision loss. There were no cases of mortality. CONCLUSIONS: CST is a rare complication of orbital and sinus disease. High clinical suspicion, early neurologic imaging, and a multidisciplinary approach to management are key factors in reducing morbidity and mortality from CST in children.
