Incidence and severity of asymptomatic ocular injury in adult and pediatric orbital fractures.

PURPOSE: To evaluate the incidence of severe ocular injury requiring emergent ophthalmic evaluation in visually asymptomatic patients presenting with orbital fractures. METHODS: We performed a retrospective chart review of all adult and pediatric orbital fractures between 2012-2022 at a level 1 trauma center. Ocular injuries were categorized into severe, moderate, and mild. We evaluated symptoms, mechanism of injury, visual acuity (VA), and severity of injuries using the Cochran-Armitage and linear-by-linear tests. RESULTS: Of the 2495 cases, 1534 had ophthalmology evaluation. The mean ± standard deviation age was 40.4 ± 20.4 years. Most patients were male (73.1%) and Caucasian (75.9%). The mean time to evaluation was 0.6 ± 2.5 days. 486 (31.7%) were visually symptomatic, 760 (49.5%) were asymptomatic, and 288 (18.8%) were unknown. Of the symptomatic, 135 (27.8%) had severe injuries, 108 (22.2%) had moderate injuries, 216 (44.4%) had mild injuries, and 27 (5.6%) had no injuries. Of the asymptomatic, 67 (8.8%) had severe injuries, 183 (24.1%) had moderate injuries, 468 (61.6%) had mild injuries, and 42 (5.5%) had no injuries. Symptoms correlated with injury severity (p-value <.001). The most common mechanism of injury were falls (24.0%), assaults (22.2%), and motor vehicle accidents (14.8%). CONCLUSIONS: Visually asymptomatic orbital fractures were less likely to have severe ocular injuries; however, many patients were unable to express symptoms. Emergent ophthalmology evaluation should be considered in all patients presenting with orbital fractures, especially patients with visual symptoms or are unable to report symptoms.

Interdisciplinary Protocol for the Management of Vision-Threatening Papilledema.

BACKGROUND: This study evaluates the effectiveness of a multidisciplinary protocol for management of patients with papilledema and vision loss secondary to increased intracranial pressure. METHODS: Retrospective record review of all adult patients who presented with vision-threatening papilledema (VTPE) and were treated under this protocol. Patients are admitted for lumbar drain placement and diuretics and followed daily to determine if they may be managed medically or require surgery (optic nerve sheath fenestration [ONSF] and/or cerebrospinal fluid [CSF] shunting). RESULTS: Nineteen patients were included. Twelve had body mass index in the obese range and 6 were morbidly obese. Fourteen had idiopathic intracranial hypertension. Five had secondary pseudotumor cerebri syndrome related to medication use, dural venous sinus thrombosis, hypothyroidism, end-stage renal disease, pulmonary disease, and diastolic heart failure. Three patients did not require surgery and were discharged on oral diuretics; 3 patients underwent unilateral ONSF, 9 underwent bilateral ONSF, and 4 underwent bilateral ONSF followed by ventriculoperitoneal shunt placement. The average follow-up was 10.1 months. The visual acuity improved bilaterally in 12 patients and unilaterally in 4 patients. The remaining 3 patients had worsened vision in both eyes. Fifteen patients had bilateral improvement in their visual fields. Five eyes in 3 patients showed further constriction of the visual field at follow-up. CONCLUSIONS: We demonstrate how a multidisciplinary complex care protocol for treating VTPE can expedite and streamline treatment and restore vision. We found that most patients had improved symptoms and signs, including visual acuity, visual fields, and papilledema. We encourage institutions that manage VTPE to adopt similar institutional protocols.

Ipilimumab-related orbitopathy: a case report.

Ipilimumab, an immune checkpoint inhibitor used in the treatment of metastatic melanoma, can cause immune-related adverse events including rare ocular-related inflammation. This is a case of a 54-year-old man with metastatic melanoma and bilateral orbital inflammation associated with ipilimumab that occurred after drug rechallenge 6 years after initial orbital inflammation with ipilimumab use. Imaging revealed tendon-involving myositis. He was managed with intravenous corticosteroid and intravenous immunoglobulin therapy with improvement in his orbital inflammation. This case demonstrates the potential ocular effects of ipilimumab use, differentiation of ipilimumab-associated orbital inflammation from thyroid orbitopathy and management considerations to effectively reduce orbital inflammation.

The Emergence of Zoonotic Onchocerca lupi Infection in the United States--A Case-Series.

This case-series describes the 6 human infections with Onchocerca lupi, a parasite known to infect cats and dogs, that have been identified in the United States since 2013. Unlike cases reported outside the country, the American patients have not had subconjunctival nodules but have manifested more invasive disease (eg, spinal, orbital, and subdermal nodules). Diagnosis remains challenging in the absence of a serologic test. Treatment should be guided by what is done for Onchocerca volvulus as there are no data for O. lupi. Available evidence suggests that there may be transmission in southwestern United States, but the risk of transmission to humans is not known. Research is needed to better define the burden of disease in the United States and develop appropriately-targeted prevention strategies.

Multimodality Image-Guided Sclerotherapy of Low-Flow Orbital Vascular Malformations: Report of Single-Center Experience.

PURPOSE: To evaluate the role of multimodality imaging tools for intraprocedural guidance and outcome evaluation during sclerotherapy of low-flow orbital vascular malformations. MATERIALS AND METHODS: A retrospective review was performed of 17 consecutive patients with low-flow orbital malformations (14 lymphatic, two venous, and one venolymphatic) who underwent multimodality image-guided sclerotherapy between November 2012 and May 2015. Sclerotherapy technique, image guidance tools, and complications were recorded. Sclerotherapy outcome was evaluated using clinical response, magnetic resonance (MR) image-based lesion volumetry, and proptosis quantification. RESULTS: There were 22 sclerotherapy sessions performed. Intraprocedural ultrasound (US), fluoroscopy, cone-beam computed tomography (CT) and MR image fusion were used for image guidance with 100% technical success. Resolution of presenting symptoms was observed in all patients at 1-month follow-up. Four major sclerotherapy complications were successfully managed. Statistically significant reduction in lesion volume (P = .001) and proptosis (P = .0117) by MR image analysis was achieved in all patients in whom 3-month follow-up MR imaging was available (n = 13/17). There was no lesion recurrence at a median follow-up of 18 months (range, 8-38 mo). CONCLUSIONS: Multimodality imaging tools, including US, fluoroscopy, cone-beam CT, and MR fusion, during sclerotherapy of low-flow orbital malformations provide intraprocedural guidance and quantitative image-based evaluation of treatment outcome.

Angiosarcoma of the Eyelid With Superimposed Enterobacter Infection.

Angiosarcoma is a rare, aggressive, malignant endothelial neoplasm with a variable clinical presentation. The authors describe a case of angiosarcoma involving the eyelid that was complicated by a superimposed Enterobacter infection. Following positive cultures for E. aerogenes and multiple biopsies suspicious but not definitive for angiosarcoma, a final biopsy was consistent with angiosarcoma.

Proptosis Caused by Rhabdomyomatous Mesenchymal Hamartomata Occurring in the Orbit.

Two infants were referred for progressive orbital proptosis. MRI in both cases demonstrated a homogenous mass in the orbit adherent to and isointense with a rectus muscle. Histopathology in both cases demonstrated a bland proliferation of spindle cells with entrapped skeletal muscle. Immunochemistry demonstrated that the abnormal tissue was of skeletal muscle origin, consistent with rhabdomyomatous mesenchymal hamartoma (RMH). Observation was elected due to the reported benign nature of RMH. In contrast to RMH of the cutaneous tissues that typically follows a benign course, RMH of the orbit may present with rapid growth.

Porcine dermal collagen in lower eyelid retraction repair.

PURPOSE: To describe clinical outcomes of patients receiving porcine dermal matrix implants for lower eyelid retraction repair. METHODS: A retrospective review of all patients who underwent lower eyelid retraction repair with porcine dermal matrix implantation between June 2007 and July 2013 at a tertiary care center was conducted. Patient demographics, procedure(s) performed, preoperative and postoperative marginal reflex distance, inferior scleral show, and complications were reviewed. Patients with a prior history of lower eyelid surgery were excluded. The study is Health Insurance Portability and Accountability Act compliant, institutional review board approved, and adherent to the Declaration of Helsinki. RESULTS: One hundred patients (160 eyelids) received porcine dermal collagen implants. Fifty-six patients had thyroid eye disease, 23 had midface descent, 10 had seventh nerve palsies, and 11 had other etiologies of retraction. The average preoperative marginal reflex distance was 7.64 mm in the OD and 7.17 mm in the OS, compared with 6.40 mm in the OD and 6.22 mm in the OS postoperatively. The average preoperative inferior scleral show was 2.04 in the OD and 1.70 in the OS compared with 0.81 mm in the OD and 0.65 mm in the OS postoperatively. Follow up ranged from 1.46 to 66.04 months, with an average of 14.06 months and median of 8.84 months. Nineteen eyelids had implant-related complications: 7 with cyst formation, 7 with exposure/rejection, 2 with long-term pain, 2 with transient inflammation, and 3 with irregular implant contour. CONCLUSIONS: Porcine dermal matrix implants provide reliable support, integration, and function in lower eyelid retraction repair without significant resorption or complications in the majority of patients.

Chronic Conjunctivitis due to Nocardia nova Complex Formation on a Silicone Stent: A Case Report and Review of the Literature.

Nocardial conjunctivitis associated with silicone tubing is an extremely rare finding. The authors present a case of a 52-year-old woman with previous dacryocystorhinostomy and silicone tube placement 3 years prior who presented with OD redness and discharge for 1 week. On examination, the patient was noted to have mucoid discharge and crusting surrounding the silicone tube. The tube debris was sampled, and the culture was positive for Nocardia nova complex sensitive to trimethoprim/sulfamethoxazole and amikacin. Silicone tube colonization and N. nova complex conjunctivitis are both rare but should be considered in the differential diagnosis of patients with indwelling silicone tubes presenting with chronic conjunctivitis resistant to fluoroquinolones and tobramycin.

Changes in Intraocular Pressure During Orbital Floor Fracture Repair.

PURPOSE: To evaluate changes in intraocular pressure (IOP) during orbital floor fracture repair. METHODS: Retrospective chart review of patients undergoing isolated orbital floor fracture repair with implant placement at a level 1 trauma center and tertiary care center. Patients with combined zygomaticomaxillary or medial wall fracture repair, or other significant ocular injuries were excluded. IOP measurements using a handheld applanation tonometer were recorded immediately after induction of anesthesia, immediately after orbital floor implant placement, and on postoperative day 1. RESULTS: Nine patients who underwent isolated orbital floor fracture repair were examined. There was a statistically significant mean decrease of 4.66 mmHg (p < 0.05) in IOP from prior to surgical to immediately after implant placement. There was also a significant mean increase in IOP of 7.44 mmHg (p < 0.05) at postoperative day 1 compared with immediately after implant placement. There was no statistically significant difference in IOP between prior to surgical incision and postoperative day 1. CONCLUSIONS: All patients who underwent orbital floor fracture repair in this study had a significant decrease in IOP during orbital floor fracture repair that returned to immediately preoperative levels by postoperative day 1. This initial decrease in IOP may be because of intraoperative manipulation of the globe.

Mucosa-associated lymphoid tissue lymphoma masquerading as herniated orbital fat.

Lymphomas are the most common primary orbital malignancies in adults. The authors present a 62-year-old Hispanic woman with a 2-year history of slowly enlarging bilateral lower eyelid masses that the patient described as "bags." On palpation, firm, mobile, nontender masses with associated tear trough deformities were noted. Biopsy of the left lower eyelid mass was consistent with a mucosa-associated lymphoid tissue lymphoma. Herniated orbital fat is an extremely common finding in the aging population and is often associated with a prominent tear trough. The patient with orbital lymphoma appeared to have herniated orbital fat with associated tear trough deformities. Lymphoma resembling herniated orbital fat is uncommon but should be considered in all patients with prominence in the periorbital region.

PROSE treatment for lagophthalmos and exposure keratopathy.

Prosthetic replacement of the ocular surface ecosystem is a treatment developed by the Boston Foundation for Sight that uses a Food and Drug Administration-approved prosthetic device for the treatment of severe ocular surface disease to improve vision and discomfort in addition to supporting the ocular surface. Facial nerve paralysis has multiple causes including trauma, surgery, tumor, stroke, and congenital lagophthalmos. Subsequent lagophthalmos leading to exposure keratitis has been treated with copious lubrication, tarsorrhapy, eyelid weights, chemodenervation to yield protective ptosis, and palpebral spring insertion. Each of these treatments, however, has limitations and potential complications. The prosthetic replacement of the ocular surface ecosystem device provides a liquid bandage to protect the cornea from eyelid interaction and dessication in addition to improving vision. This report describes 4 patients with exposure keratitis who were successfully treated with prosthetic replacement of the ocular surface ecosystem devices at 2 clinical sites.

Strenotrophomonas maltophilia-related chronic dacryocystitis.

Dacryocystitis related to Stenotrophomonas maltophilia is rare. We describe a case of Strenotrophomonas maltophilia-related chronic dacryocystitis with associated coagulase-negative Staphylococcus. Following external dacryocystorhinostomy without intraoperative or postoperative antibiotics, her discharge and lacrimal sac fullness resolved.

Eyelid lipomas: a case report and review of the literature.

Simple lipomas of the eyelid are rare. We present a case of a 61-year-old man, who presented with 6 months of a slowly worsening blepharoptosis. On examination, that patient was noted to have a palpable, soft mass in the medial left upper eyelid. Histopathological examination of the mass revealed mature adipose tissue most consistent with lipoma. Simple lipomas of the eyelid are very unusual but should be considered in the differential diagnosis of patients presenting with mechanical ptosis.

Tuberculosis of the nasolacrimal duct.

Nasolacrimal tuberculosis is rare. The authors present a young Peruvian-born female with subacute onset of right eye epiphora, isolated right inferior turbinate enlargement, and ipsilateral cervical lymphadenopathy. Turbinate and neck mass incisional biopsies demonstrated histopathological findings consistent with tuberculosis. QuantiFERON-TB Gold-In-Tube testing was positive. Complete resolution of symptoms occurred after dacryocystorhinostomy and 9 months of standard 4-drug antituberculosis therapy. Tuberculosis of the nasolacrimal duct is highly unusual but should be considered in patients with tuberculosis risk factors who present with nasolacrimal obstruction from an inferior turbinate mass.

Adjunctive techniques to dacryocystorhinostomy: an evidence-based review with recommendations.

BACKGROUND: Many adjunctive techniques exist for dacryocystorhinostomy (DCR), with varying levels of supportive evidence. METHODS: Literature from PubMed, EMBASE, and Cochrane Databases was reviewed between January 1990 and January 2020 to examine evidence regarding the utility of adjunctive techniques to DCR, including mucosal flap preservation, concurrent septoplasty, stenting, topical mitomycin C (MMC), and 5-fluorouracil (5-FU), as well as perioperative antibiotics and steroids. Recommendations were made based on the evidence found. RESULTS: Seven adjunctive techniques used in DCR were examined. The literature supported concurrent septoplasty when septal deviation is present. Silicone stents are recommended for external DCR approaches. MMC use is optional in external DCR and revision cases. The literature does not support the routine use of silicone stents or MMC in primary endoscopic DCR. Mucosal flap preservation is optional, with evidence showing comparable results with or without utilization. The level of evidence is limited for topical 5-FU, as well as perioperative antibiotic and steroid use. CONCLUSION: Recommendations for adjunctive techniques to external and endoscopic DCR surgeries can be made based on the current literature. Higher-level studies are needed to better optimize perioperative approaches to DCR.
