An Adult Loa loa Worm in the Upper Eyelid: An Atypical Presentation of Loiasis in the United States.

Purpose. To report a case of ocular involvement of Loa loa parasite. Observations. We present a rare case report of a Loiasis diagnosed in the United States from a patient presenting with subcutaneous migration of an adult worm within an eyelid who was found to have systemic disease with microfilaria in his blood. This is the second report in the United States and the eighth case in published literature worldwide. Conclusions and Importance. Due to the relatively mild disease course, Loiasis is relatively ignored in public health in low resource health districts. Understandably, the focus of public health in endemic areas must focus on basic health needs like malnutrition and diseases that entail a greater disease burden. As globalization has increased the amount of trade of physical goods, the effect of immigration also has implications for the spread of infectious disease. Medical practitioners in the United States should be aware of endemic diseases from foreign lands.

Surgical Approaches to the Orbit: Transpalpebral.

The aim of this study is to provide an overview of the safe and effective incisional transpalpebral approaches to the orbit. The location of each approach and pertinent anatomy in each respective area, suggested approach techniques, recommended specialties, reconstruction options, intraoperative neurophysiology, complications, and approach limitations are discussed in detail.

The Ophthalmology Chief Resident: Does Surgical Volume Correlate With Likelihood of Selection?

PURPOSE: Investigate whether number of logged Accreditation Council for Graduate Medical Education (ACGME) surgical cases correlates with likelihood of Virginia Commonwealth University Health System (VCUHS) ophthalmology residents being selected as the chief resident. DESIGN: Retrospective study. PARTICIPANTS: VCUHS ophthalmology residents from 2006 to 2016. METHODS: Analyze association between chief resident selection and logged cases. MAIN OUTCOME MEASURES: Review number of archived logged ACGME surgical cases of all residents between the years 2006 and 2017. Review chief resident selected each year 2006-2016. RESULTS: Our analysis correctly predicted the chief resident in 2 of the 10 years analyzed. CONCLUSION: Those residents performing the most surgical procedures in each respective class were not more likely to be selected as chief resident.

Atypical presentation of isolated orbital Langerhans cell histiocytosis.

BACKGROUND: A 9-year old female presented with one month of waxing and waning upper eyelid swelling. An excisional biopsy via anterior orbitotomy was performed. OBJECTIVE: To describe a patient presenting atypically with symptoms concerning for orbital cellulitis who was diagnosed with Langerhans cell histiocytosis (LCH). METHODS: Description of case report. RESULTS: We report a case of a 9-year old female with one month of periorbital edema and erythema suspected to be orbital cellulitis. A complete ophthalmological exam, subsequent imaging, and an excisional biopsy revealed the diagnosis of LCH. With a confirmed diagnosis, the patient started chemotherapy indicated by the Histiocyte Society Evaluation and Treatment Guidelines. CONCLUSION: Langerhans cell histiocytosis (LCH) embodies a spectrum of diseases with the primary pathologic process being the abnormal proliferation of polyclonal Langerhans cells. In children with isolated bony involvement, the most common presenting symptom is pain. Rarely is orbital involvement with associated periorbital edema and erythema the primary presentation.

INTRAOCULAR SYNOVIAL SARCOMA.

PURPOSE: To describe the first reported case of intraocular synovial sarcoma. METHODS: A 29-year-old man was enucleated for a blind, painful eye. Pathologic examination revealed an unexpected intraocular spindle cell tumor. RESULTS: Immunohistochemical characterization revealed diffuse reactivity of the tumor cells for vimentin and focal positivity for epithelial markers pankeratin and epithelial membrane antigen. Melanoma markers were negative. Fluorescent in situ hybridization studies identified a t(X;18) (p11.2;q11.2) translocation, establishing a final diagnosis of synovial sarcoma. There was no evidence of extraocular extension as the resected margin of the optic nerve was free of tumor. Further imaging studies revealed no extraocular primary site or metastasis. CONCLUSION: The incidental discovery of an intraocular malignancy in this case underscores the importance of routine histopathologic analysis of all enucleated globes. To the authors' knowledge, this is the first reported case of an intraocular synovial sarcoma, either as metastasis or as primary site.

Visual Acuity in Orbital Floor Fractures: Does Surgical Subspecialty Management Matter?

PURPOSE: At the time of this writing, there is no consensus regarding orbital floor fracture (OFFx) management. Proper management of OFFxs is imperative to help prevent well known complications and the possibility of decreased visual acuity (VA). The VA outcomes have been largely underreported in the literature. The current study identifies the complications of the different subspecialty management including VA outcome. METHODS: A retrospective chart review study was performed to identify patients who suffered an OFFx and were managed by ophthalmology alone or in conjunction with either ENT or oral maxillofacial surgery at a single hospital. The primary outcome included VA at injury and subsequent visits. Secondary outcomes included epiphora, diplopia, enophthalmos, infraorbital dysesthesia, and decreased motility. Data were analyzed using Microsoft Office Excel 2007 using the Student t-test to find a P value < 0.05. RESULTS: There were 54 patients with OFFx. The majority were Black (83.3%) and men (77.8%) with their average age at time of injury being 37.6 (SE = 17.02) years. The majority of OFFxs were secondary to assault (65%). The average follow-up was 2.84 (SE = 5.38) months. The 34 patients who did not undergo surgical correction had statistically significant improvement of their VA by 1 week after injury (P = 0.02). There was no statistically significant improvement in VA outcomes for surgical patients of ophthalmology (P = 0.45) or oral maxillofacial surgery (P = 0.12). CONCLUSIONS: Patients undergoing OFFx repair did not have improved VA. The VA of nonsurgical patients was statistically significantly improved by 1 week after injury (P = 0.02).

Extranodal marginal zone B cell lymphoma of the orbit in a patient with sarcoidosis: a case report.

OBJECTIVE: To describe a case of extranodal marginal zone B-cell lymphoma (EMZL) "mucosa associated lymphoid tissue (MALT)" of the orbit that presented with stage IV disease in a patient with sarcoidosis. DESIGN: Clinicopathologic case report. METHODS: Biopsies of the lesion were performed in the operating room and the samples were submitted for pathology processing. Pathology analysis identified the lesion as an extranodal marginal zone B-cell lymphoma "mucosa associated lymphoid tissue (MALT)" via flow cytometry, histopathology, cytogenetics, and immunohistochemical staining and fluorescent in situ hybridization (FISH). The institutional review board of Howard University Hospital waived the need for IRB approval for this intraoperative finding. RESULTS: A 70-year-old Black woman with biopsy-proven sarcoidosis presented complaining of foreign body sensation, redness, swelling of her left upper eyelid and tearing. The patient was found to have an orbital lymphoproliferative malignancy. CONCLUSIONS: It is still unclear if the presence of immunosuppression or an autoimmune disease increases the risk of lymphoproliferative malignancies {6}. Malignancy should always be suspected and investigated.
