Hybrid Schwannoma-Perineurioma of the Orbit.

A 52-year-old woman presented with a 6-month history of progressive right proptosis associated with intermittent right retrobulbar and facial pain. MRI revealed a heterogeneously enhancing, well-circumscribed, ovoid, soft tissue mass in the intraconal space near the right orbital apex displacing the optic nerve medially. Excisional biopsy established the diagnosis of a schwannoma-perineurioma hybrid peripheral nerve sheath tumor (HPNST). This case represents only the second reported occurrence, to our knowledge, of an orbital schwannoma-perineurioma HPNST.

Epidemiology of United States tennis-related ocular injuries from 2000 to 2019.

PURPOSE: To characterize trends in ocular tennis injuries over the last 20 years. METHODS: The National Electronic Injury Surveillance System was utilized to characterize tennis-related eye injuries in a nationally representative sample of emergency department visits. Data were divided into 5 age groups, and various demographic information was obtained. RESULTS: Approximately 16,000 tennis-related ocular injuries were identified with males being affected nearly 2:1 compared to females. The youngest age group (0-20) had the greatest proportion of injuries, with most injuries in boys 11-15 years old. Injuries occurred most often during the spring season. Most patients were treated and released from the ED. Of those patients who were hospitalized, one-third had an open globe injury. CONCLUSIONS: The overall number of injuries trended downward during the timespan of the study. Although most patients did not experience serious visual consequences, the greatest proportion of ocular tennis injuries occurred in the pediatric age group in whom the risk of amblyopia is high. Primary care providers and tennis regulatory bodies should consider recommending eye safety sports goggles in children to mitigate the potential for significant visual morbidity.

Enucleation in pediatric open globe injuries: demographics and risk factors.

PURPOSE: The purpose of this study is to report the demographics and risk factors for undergoing primary enucleation in the setting of acute open globe injury (OGI) in the pediatric population in the USA. METHODS: This retrospective, cross-sectional study of pediatric patients with OGIs in the USA between 2002 and 2014 was conducted utilizing data from the National Inpatient Sample Database. Descriptive statistics, chi-square testing, and univariate and multivariable analyses were performed. RESULTS: In the USA, 8944 cases of pediatric OGI were identified between 2002 and 2014 in the NIS Database, of which 344 underwent primary enucleation. Blacks and Asian/Pacific Islanders made up higher proportions of enucleated cases compared to non-enucleated cases. Older age, male sex, being Black or Asian/Pacific Islander, OGI with an intraocular foreign body, rupture type OGI, and concurrent endophthalmitis were identified as risk factors for undergoing enucleation. There was no significant difference in insurance status among enucleated versus non-enucleated cases. Mean length of hospital stay (in days) was almost 3 times higher in enucleated OGIs. By hospital's geographic location, the Midwest hospitals had a greater proportion of enucleated versus non-enucleated cases compared to other regions. CONCLUSION: Significant demographic differences were identified in OGI patients that underwent primary enucleation versus repair with regard to age, sex, race, the geographic location of hospital admission, mean length of hospital stay, type of ocular injury, and other ocular complications. Most pediatric traumatic enucleations between 2002 and 2014 were reported in teenagers (16-20 age group), in males, and in Blacks.

Second Primary Neoplasms in Patients With Sebaceous Carcinoma of the Eyelid: A Population-based Study, 2000 to 2016.

PURPOSE: To investigate the risk of second primary neoplasms (SPNs) after primary sebaceous carcinoma of the eyelid (SCE). METHODS: Data on patients diagnosed with primary SCE as their first malignancy were extracted from the Surveillance, Epidemiology, and End Results database from 2000 to 2016. Observed-to-expected ratios of SPNs were calculated to estimate standardized incidence ratios (SIRs). Patients were compared with a reference population (RP) matched for age, gender, and race. RESULTS: Five hundred fifty-nine patients with primary SCE were identified, 16% of whom developed SPNs. SCE patients displayed a 61% increased risk of developing SPNs compared with the RP (p < 0.001). Overall, the risk of SPNs of the lungs (SIR = 1.82; p < 0.05), pancreas (SIR = 2.94; p < 0.05), salivary glands (SIR = 41.65; p < 0.001), and skin (SIR = 8.33; p < 0.05) was elevated. Only non-Hispanic Whites were at an increased risk (SIR = 1.51; p < 0.05). Patients 40-54 years old at the time of diagnosis were at the highest risk of developing SPNs compared with the RP (SIR = 3.15; p < 0.05). Women with SCE experienced an increased risk of breast cancer (SIR = 3.6; p < 0.05) and chronic lymphocytic leukemia (SIR = 8.8; p < 0.01). CONCLUSION: SCE patients are more likely to develop SPNs of the lungs, pancreas, salivary gland, and skin than the RP. Forty to fifty-four years old Caucasian patients are at the highest risk. Women are at an increased risk of developing breast malignancies and chronic lymphocytic leukemia. Clinicians should be cognizant of these risks when managing SCE patients.

Orbital glomangiopericytoma in a 5-year-old child.

A 5-year-old girl presented with a 6-month history of strabismus and painless left proptosis. Magnetic resonance imaging revealed a homogenously enhancing, anterior, superomedial, left orbital mass. Excisional biopsy established the diagnosis of orbital glomangiopericytoma. Glomangiopericytoma of soft tissue is a perivascular myoid neoplasm with hemangiocytoma-like vascular channels that has overlapping features between glomus tumor and myopericytoma. To the authors' knowledge, glomangiopericytoma of the orbit has not previously been reported.

Predictive factors of enucleation after open globe injuries.

BACKGROUND: Trauma is the leading cause of enucleations in the USA. Current information regarding open globe injuries (OGI) is based mainly on data from individual tertiary care centers across the country which might skew the findings towards the population served by these level-one trauma centers. The aim of this study is to evaluate the demographics, characteristics, and risk factors of traumatic enucleations in a large data sample. METHODS: Descriptive cross-sectional observational study using the National Inpatient Sample (NIS) Database from 2002 to 2013. Inpatients with traumatic enucleations were identified using ICD-9 codes. Chi-square and logistic regression analyses were used to identify differences between the enucleated and non-enucleated cohorts and to evaluate the predictive factors of enucleation in OGIs. RESULTS: Enucleations were performed in 3020 (6.2%) of 48,563 OGIs identified. The average age in the enucleated cohort for males vs. females was 44.7 vs. 62.2 years. In the USA, the highest number of traumatic enucleations occurred in the 21-40 group (41.8%) and the fewest in the 80+ age group (11.8%). The risk of enucleation decreased across the age groups significantly. Compared with the 21-40 age group, the risk of undergoing enucleation was 15% lower in patients 41 to 60 years of age, 35% in patients 61 to 80, and 40% lower in patients over 80. In total, 5.1% OGIs in women and 6.7% of OGIs in men were enucleated. The risk of enucleation was 29% higher in men than in women. The highest absolute number of enucleations was seen in Whites. Compared with Whites, Blacks had a 63% higher risk of enucleation following an OGI. OGIs with rupture-type injury, endophthalmitis, or phthisis were significantly higher odds to be enucleated. CONCLUSIONS: The risk of enucleation following traumatic OGI significantly increased for patients who were in the 21-40 age group, of Black race, or of male gender; the risk also increased if the injury was a rupture-type or associated with endophthalmitis or phthisis. The risk of depression was 75% higher in enucleated patients versus non-enucleated patients.

Myoepithelioma of the Lower Eyelid.

A 59-year-old woman presented with a 4-year history of a progressively growing, subcutaneous, painless, left lower eyelid mass with associated swelling and discomfort. Excisional biopsy established the diagnosis of a myoepithelioma, a tumor which, to the authors' knowledge, has not been previously reported in the lower eyelid.

Orbital Lymphangioma Confined to an Extraocular Muscle.

A 48-year-old woman presented with a 1-year history of an enlarging, nontender right lateral intrapalpebral mass overlying the insertion of the right lateral rectus muscle, associated with a 3-month history of worsening right orbital pain and retrobulbar headaches. MR imaging revealed an isointense right orbital mass contained entirely within the right lateral rectus muscle and indistinguishable from it. Transconjunctival biopsy established the diagnosis of lymphangioma. To the authors' knowledge, this case represents the first reported orbital lymphangioma contained entirely within an extraocular muscle.

Lacrimal Gland Ductal Cyst Complicated by Abscess Formation.

A 52-year-old woman with a 7-month history of a left lateral upper eyelid nodule presented with an acute, 1-day history of left upper eyelid swelling and erythema associated with chemosis, epiphora, and pain. Magnetic resonance (MR) imaging revealed a well-circumscribed cystic mass indistinguishable from the left lacrimal gland containing a fluid-fluid level. Surgery confirmed an abscess within the lacrimal gland; histopathologic examination revealed a dilated lacrimal duct with an inflammatory exudate within the lumen. This report details one of the few reported cases of an acute lacrimal gland ductal cyst abscess and, to the authors' knowledge, the first with MR images.

Intravascular papillary endothelial hyperplasia of the periocular region.

Intravascular papillary endothelial hyperplasia (IPEH) is a benign vascular lesion, typically found in the skin, consisting of a papillary proliferation of endothelial cells intimately related to a thrombus; it appears to be a rare variant of an organizing process. IPEH very rarely develops in the periocular region, with fewer than 20 such cases currently reported in the English language literature. We describe one of the largest ever case series of this uncommon lesion occurring in the periocular region and discuss its clinical features, imaging characteristics, and surgical management.

Chronic, Symptomatic Orbital Inflammation Resulting From Retained Bone Wax.

A 58-year-old man presented with a 9-month history of a chronically draining surgical wound and low-grade periorbital inflammation following a right lateral orbitotomy. Imaging of the right orbit revealed a peculiar lesion in the right lateral orbit that was hypointense on both T1- and T2-weighted MRI with peripheral enhancement. Exploratory orbitotomy and biopsy established the diagnosis of a chronic foreign body inflammatory reaction to bone wax; symptoms resolved following evacuation of the retained foreign material.A 58-year-old man developed a chronic, symptomatic, inflammatory reaction to bone wax following a lateral orbitotomy; only once previously has symptomatic orbital inflammation following orbital surgery as a result of bone wax been reported.

Clinical and Magnetic Resonance Imaging Characteristics of Postfenestration Optic Nerve Sheath Pseudomeningoceles.

PURPOSE: The clinical significance of postoperative pseudomeningocele formation following optic nerve sheath fenestration (ONSF) has not been fully characterized. A literature review identifies 9 previously published cases the authors believe demonstrate pseudomeningocele formation and approximately 19 other similar findings that were either transient or less defined blebs. This study was undertaken to more clearly define the clinical, radiographic, and histopathologic features associated with this entity. METHODS: Sixteen-year, single-center, retrospective chart review of all ONSF cases performed by 2 surgeons. Clinical data, intracranial pressure, radiographic imaging, and histopathology of clinically detected pseudomeningoceles after ONSF were reviewed. RESULTS: Eighty-six eyes in 57 patients underwent ONSF (28 unilateral, 12 bilateral sequential, 17 bilateral simultaneous). Forty-nine of 57 patients had elevated intracranial pressure preoperatively (41 idiopathic intracranial hypertension, 4 venous thrombosis, 2 meningitis, 1 arteriovenous malformation, and 1 sarcoid). In 32 patients undergoing postoperative imaging, 4 eyes (4.7%) in 4 patients developed well-defined pseudomeningoceles, of which 3 were symptomatic and 2 required surgical revision. Each pseudomeningocele developed in the setting of elevated preoperative intracranial pressure (350, 360, 430, 500 mm H20). Magnetic resonance imaging and/or computed tomography revealed sharply demarcated fluid-filled sacs adjacent to the optic nerve. The contents of these sacs were hypointense on T1-weighted imaging, hyperintense on T2-weighting, variably enhanced with contrast, and hypointense on fluid attenuated inversion recovery, and were thus consistent with cerebrospinal fluid. Histopathologic analysis of one of these outpouchings demonstrated an acellular, fibrocollagenized lining consistent with pseudomeningocele. Three eyes in 3 additional patients had less well-defined findings on imaging interpreted as bleb-like or cyst-like change. CONCLUSIONS: Pseudomeningoceles following ONSF may be asymptomatic or may cause symptomatic orbital mass effect and rarely visual loss, amendable to surgical excision. Post-ONSF pseudomeningoceles are identified on computed tomography or magnetic resonance imaging to occur at the locations of fenestration sites and contain cerebrospinal fluid communicating with the subdural space that may act as a "filtration" bleb in some cases. Imaging findings may represent a spectrum spanning intraorbital cerebrospinal fluid leakage, partial walling off of bleb, or fully developed cysts. Resection of optic nerve pseudomeningoceles is considered in symptomatic cysts or eyes with papilledema that fails to improve.

The microbiologic profile of dacryocystitis.

PURPOSE: Recent studies suggest an increasing incidence of gram-negative bacteria and methicillin-resistant Staphylococcus aureus in dacryocystitis. Since patients are often treated empirically without culture data, a changing microbiologic profile will markedly affect the success of oral treatment. To provide current guidelines for the treatment of this common condition, we investigated the microbiology and antibiogram of dacryocystitis seen at our institution. METHODS: The charts of all patients presenting with acute and/or chronic dacryocystitis in University Hospital, Newark, from 2007 to 2015 were reviewed. Patient demographics, culture isolates, and in vitro antimicrobial susceptibility data were collected. Additional sensitivity data were obtained from the Sanford Guide to Antimicrobial Therapy. RESULTS: A total of 137 patients were included in the study. Of 205 samples collected, S. aureus was the most commonly isolated organism (46 of 156, 30%) followed by Pseudomonas species (19 of 156, 12%) and Propionibacterium acnes (15 of 156, 10%). Based on sensitivity data, the two oral antibiotics that would have been most effective in this population were levofloxacin and amoxicillin/clavulanate; however, even these antibiotics would have encountered at least one resistant organism in 16% and 32% of patients, and potentially in another 15% and 8% of patients, respectively. CONCLUSIONS: Given the broad range of causative organisms, routine treatment of dacryocystitis with any specific antibiotic may fail in up to one-third of patients. Obtaining a culture at the time empiric antibiotic treatment is initiated can prove extremely valuable when treating patients with dacryocystitis.

POSTTRAUMATIC ENDOPHTHALMITIS: An 18-Year Case Series.

PURPOSE: To describe the demographics, characteristics, management, and visual outcomes of eyes diagnosed with endophthalmitis after open globe injury. METHODS: Retrospective cohort analysis of all patients diagnosed with endophthalmitis after open globe injury from 1997 to 2015 at University Hospital, Newark, NJ. RESULTS: Twenty-six eyes were identified (all male patients; mean age: 37 ± 15 years). Cultures were positive in 16 eyes (62%), with Staphylococcus species (7 eyes, 44%) being the most common organism. Twelve eyes (46%) presented with open globe injury and concurrent endophthalmitis; 14 eyes (54%) developed endophthalmitis a mean of 14 days after open globe repair (OGR; 1 outlier of 98 days excluded). All eyes were managed with systemic and intravitreal antibiotics. The presence of intraocular foreign body (P < 0.05) and delayed primary OGR (P < 0.03) were significantly more common with concurrent versus post-OGR endophthalmitis. Four (29%) eyes in the post-OGR endophthalmitis group had corneal wound leak after OGR. Four (15%) eyes with no light perception vision were enucleated. Ten (40%) of 25 eyes with documented best-corrected visual acuity had final best-corrected visual acuity ≥20/200; final best-corrected visual acuity ranged from no light perception to 20/20. CONCLUSION: The presence of intraocular foreign body and delayed presentation were significantly more common with concurrent endophthalmitis. Twenty-nine percent of eyes that presented with endophthalmitis after OGR had a wound leak. Final best-corrected visual acuity ≥20/200 was achieved in 40% of cases.

Orbital Hobnail Hemangioma.

A 64-year-old woman presented with a 1 year history of progressive left proptosis and "blurry vision." Imaging studies revealed a left superior orbital mass distorting the optic nerve and superior rectus muscle. Excisional biopsy established the diagnosis of hobnail hemangioma. This report describes the first case of an orbital hobnail hemangioma, a lesion that more commonly presents in the dermis.

Pediatric orbital blowout fractures.

PURPOSE OF REVIEW: The current study reviews the recent literature on pediatric orbital blowout fractures and provides guidelines on their management. RECENT FINDINGS: The most common problem among patients requiring surgical revision of a previously repaired orbital floor fracture is an improperly placed orbital floor implant, usually erroneously placed under the posterior bony ledge. Although the transconjunctival incision can be combined with a lateral canthotomy and cantholysis, excellent surgical exposure can be obtained without the need for these latter relaxing maneuvers. In surgically repaired pediatric orbital blowout fractures with preoperative diplopia (both trapdoor and nontrapdoor), approximately 85% of patients recover completely over time. Delayed orbital tissue atrophy may play a role in the development of late enophthalmos. SUMMARY: Most cases of pediatric orbital fracture can initially be followed conservatively to determine if disabling diplopia, when present, resolves without surgery. A notable exception is the trapdoor fracture, in which herniated tissue becomes entrapped by a recoiled bone fragment, causing marked or complete reduction in motility and/or an oculocardiac reflex; we recommend that these fractures be repaired within 24 h from the time of diagnosis. Enophthalmos resulting from an orbital floor fracture does not need to be prevented with early surgery. Enophthalmos can be allowed to develop over time to determine if it is noticeable, and then repair undertaken, if necessary, at that time. When surgery is indicated, a simple transconjunctival incision is preferred over a cutaneous incision, and care should be taken to insure that the implant is placed on the bony ledge at the posterior edge of the defect. Many children with blowout fractures will not require surgery, and those that do usually have excellent outcomes provided the recommendations are closely followed.

Successful Treatment of Extensive Squamous Cell Carcinoma of the Conjunctiva and Upper Eyelid Skin With Topical Therapy Alone.

This study reports a case of extensive periocular squamous cell carcinoma of the conjunctiva, extending into the superior fornix, over the upper eyelid margin, and involving the superficial layers of the eyelid skin up to the eyebrow, that was successfully treated solely with topical therapy.
