Orbital Diffuse Large B-Cell Lymphoma Initially Presenting as Neovascular Glaucoma.

Orbital lymphoma can result in rapid loss of vision if not diagnosed and treated in a timely manner. This patient presented with rapid visual loss and on examination had a rubeosis iridis with a hyphema as well as neovascular glaucoma with vitreous hemorrhage. His medical history included systemic diffuse large B-cell lymphoma and a workup ultimately revealed an orbital mass in the body of the optic nerve. Optic nerve biopsy demonstrated diffuse large B-cell lymphoma. To the authors' knowledge, neovascular glaucoma as the presentation of an extraocular diffuse large B-cell lymphoma has not been reported previously. Lymphomas of the orbit and its adnexa constitute roughly 1% of all non-Hodgkin lymphoma. Most cases are marginal-zone B-cell lymphomas, with the second most common being diffuse large B-cell lymphomas. Orbital lymphomas can rapidly progress to complete visual loss when not diagnosed early. The authors report a patient who presented with rapid visual loss due to hyphema, rubeosis iridis, neovascular glaucoma and vitreous hemorrhage secondary to orbital diffuse large B-cell lymphoma. Research methods were adherent to the ethical principles outlined in the Declaration of Helsinki as amended in 2013. The collection and evaluation of protected patient health information was Health Insurance Portability and Accountability Act compliant.The authors report a case of lymphoma metastatic to the optic nerve masquerading as neovascular glaucoma with vitreous hemorrhage.

The Aesthetic Oculoplastic Surgery Video Teleconference Consult.

BACKGROUND: Skype video telemedicine consults are gaining popularity to evaluate patients from distant locations. No study has analyzed the utility of this means of patient evaluation in a cosmetic oculoplastic patient population. OBJECTIVES: The authors sought to provide an evidence-based analysis of the utility of Skype video consults in a cosmetic oculoplastic surgery patient population with regards to patient demographics, reasons for consult, and procedural conversion rate. METHODS: A 1-year retrospective chart review (May 2016 to May 2017) of patients who underwent aesthetic oculoplastic Skype consults from 2 authors' practices was performed. The authors analyzed patient demographics, referral source, chief complaint, location of residence, length of consult, and conversion to face-to-face consultation and intervention. RESULTS: Seventy-nine patients (60 women and 19 men) underwent Skype evaluations. Mean age was 49 years. Sixty-four consults (81%) lasted 15 minutes or less. Referral sources included the internet (67%), another physician (19%), self-referral (7.5%), referred by former patients (4%), and social media sites (2.5%). Consultations were obtained for revision (49%), or first-time (30%) eyelid/eyebrow surgery, cosmetic ptosis surgery (6%), laser skin procedures (5%), cosmetic orbital decompression (5%), and lower eyelid fat prolapse (5%). Twenty patients (25%) followed-up with in-person consultation. Sixteen of these patients (80%) had surgical (56%) or nonsurgical (44%) interventions. CONCLUSIONS: Skype consults are an efficient, in-office modality to increase patient flow through the office, expand patient base, and generate income. In this report, 25% of Skype contacts followed-up with formal in-person consultations, of which 80% had surgical or nonsurgical interventions.

Analysis of anterior and posterior maneuvers to enhance intraconal exposure.

BACKGROUND: The medial and inferior recti encompass the ideal surgical corridor to approach the intraconal space endonasally. Here, we describe 3 different maneuvers to achieve greater access to orbital contents through an expanded endonasal approach (EEA). METHODS: Four human cadaver heads were dissected bilaterally (n = 8). EEA to the medial intraconal orbit was executed. The following 3 maneuvers were performed: (1) anterior: extraocular muscles control (EOM); (2) posterior: annulus of Zinn (AZ) release; and (3) anterior/posterior combined. Measurements of the inferior and medial rectus corridor at the level of anterior ethmoidal artery (AEA) and posterior ethmoidal artery (PEA) and extent of optic nerve and medial rectus visualization was performed before and after each maneuver. RESULTS: Medial rectus length (MRL) and optic nerve length (ONL) achieved were 1.72 ± 0.28 cm and 0.85 ± 0.2 cm, respectively. Mean caudal-rostral distances between the rectus muscles at the level of the AEA and PEA were 3.45 ± 0.7 mm and 1.30 ± 0.3 mm, respectively. After EOM control, mean caudal-rostral distances at the same level were as follows: AEA 4.90 ± 1.15 mm (p = 0.009) and PEA 1.70 ± 0.20 mm (p = 0.016). With AZ release, MRL was 2.20 ± 0.7 cm (p = 0.002) and ONL was 1.30 ± 0.2 cm (p = 0.003), with mean rostral-caudal distance at the level of AEA at 4.03 ± 0.8 mm (p = 0.16) and PEA at 1.71 ± 0.36 mm (p = 0.039). Mean caudal-rostral distances achieved with AZ release and EOM control were as follows: AEA 5.6 ± 1.2 mm (p = 0.001) and PEA 2.15 ± 0.4 mm (p = 0.001). CONCLUSION: Progressive access to the orbital contents is afforded with the 3 delineated maneuvers. The magnitude of access is optimized with the combined maneuver. The actual anterior/posterior location of the target will determine which maneuvers are required.

In Vivo Effects of Retrobulbar Bimatoprost Injection on Orbital Fat.

PURPOSE: Recent publications have reported the adverse effects of prostaglandin analogues on the periocular tissues. These medications may cause periorbital lipodystrophy, enophthalmos, and deepening of the superior sulcus deformity. While these effects may have adverse consequences for some patients, the atrophy of the periorbital fat may have a useful role in diseases that lead to orbital and periorbital fat hypertrophy such as thyroid eye disease. In this pilot study, the authors investigated the effects of retrobulbar bimatoprost injection on the intraocular pressure and orbital fat in a rat animal model. METHODS: Three rats were sedated and intraocular pressure was measured. A 0.1 ml aliquot of bimatoprost was injected into the right orbit of all rats. In the left orbit, 0.1 ml of phosphate-buffered saline was injected as a control. Three weeks later, all rats were sedated and intraocular pressure was measured before euthanizing. Routine histologic staining was performed and thin sections through the intraconal orbital fat were obtained. Density of intraconal adipocytes was measured and adipocyte heterogeneity was determined using a computer image analysis algorithm. RESULTS: The specimens injected with bimatoprost demonstrated atrophy of orbital fat with significantly increased adipocyte density (p = 0.009) and heterogeneity (p = 0.008) when compared with control. Intraocular pressure was not significantly decreased at 3 weeks after injection of retrobulbar bimatoprost. CONCLUSIONS: In this pilot study, orbital injection of bimatoprost demonstrated atrophy of intraconal adipocytes when compared with control orbits injected with saline. The orbits injected with bimatoprost were noted to have smaller, more heterogeneous adipocytes that were densely packed in the intraconal space. The study limitations include the small sample size, which limited the ability for us to make conclusions about the effect on intraocular pressure. Nevertheless, the findings presented suggest that retrobulbar bimatoprost may present a nonsurgical alternative to induce atrophy of the orbital fat without inducing inflammation or hypotony.

The Brow Fat Pad Suspension Suture: Safety Profile and Clinical Observations.

PURPOSE: To evaluate the safety, subjectively assess outcome, and emphasize surgical pearls and critical clinical observations of upper blepharoplasty performed in conjunction with the brow fat pad suspension suture procedure, previously referred to as a "browpexy variant" or "brassiere suture procedure." METHODS: A retrospective 4-year analysis of patients who underwent the brow fat pad suspension suture with upper blepharoplasty was performed. Adjunctive procedures (brow lift and ptosis repair) were categorized. The surgical technique is detailed with emphasis placed on nuances to aid in optimal outcome. RESULTS: Two hundred and sixteen patients (149 women and 47 men) underwent upper blepharoplasty with the brow fat pad suspension suture. The average patient age is 54 years and follow up is 11 months. One hundred patients had adjudicative brow lift or ptosis repair, and in 20 patients the blepharoplasty was a revision procedure. Subjective assessment of outcome showed excellent aesthetic results with improved brow projection, and enhanced lateral tarsal platform show and eyebrow/eyelid contour. Surgical complications were infrequent and patient satisfaction was high. CONCLUSIONS: This initial large series description of the brow fat pad suspension suture demonstrates that it is a safe adjunct to upper blepharoplasty, which the authors believe subjectively improves overall outcome. Evidence-based quantitative assessments of objective measures of surgical results are currently underway.

Systemic Allergic Response in the Setting of a Metallic Intraorbital Foreign Body With Intraoperative Magnet-Assisted Retrieval.

A 12-year-old boy with a past medical history of nickel allergy was referred to our service after sustaining an air rifle injury with a retained BB in his left inferior orbit. On examination, he had a palpable orbital mass and systemic urticaria. Plain films demonstrated a spherical metallic foreign body adjacent to the left inferior orbital rim. Given his worsening systemic reaction despite oral antihistamine therapy, decision was made to remove the foreign body. In the operating room, the Allergan Magna Finder-a prepackaged, sterile device normally used for retrieval of a port used in tissue expansion surgery-was placed over the inferior conjunctiva of the lower eyelid. With the magnet holding gentle anterior traction on the foreign body, it was easily dissected and removed. The patient tolerated the procedure well, and had rapid resolution of his systemic allergic response following removal of the BB.

Osteolytic Sarcoidosis of the Orbital Roof Masquerading as a Malignant Orbital Lesion.

A 51-year-old man without a significant past medical history presented with 4 weeks of progressive swelling and drooping of his left upper eyelid. A CT of the left orbit revealed an osteolytic mass lesion in the area of the lacrimal gland. A left orbitotomy with excisional biopsy was performed. The excised tissue was sent for infectious workup and histopathological examination, which revealed osteolytic sarcoidosis. The patient was treated with systemic and local injection corticosteroids, and followed over 10 months without evidence of recurrence. Systemic workup with CT of his chest, abdomen, and pelvis revealed no further evidence of sarcoidosis. To the best of the authors knowledge, this is the first report of an otherwise healthy patient presenting with isolated osteolytic sarcoidosis of the orbit and a negative systemic workup.

Histologic Evidence of Orbital Inflammation from Retrobulbar Alcohol and Chlorpromazine Injection: A Clinicopathologic Study in Human & Rat Orbits.

PURPOSE: Retrobulbar injections of alcohol and chlorpromazine are used for the treatment of blind, painful eyes. There have been reports of inflammation after retrobulbar injections of these agents, but the histologic effects are not well characterized. A clinical case with histopathologic confirmation of inflammation after retrobulbar alcohol injection led the authors to develop a rat model to examine these effects. METHODS: Adult Lewis rats were given retrobulbar injections of either 0.1 ml of absolute alcohol or 25 mg/ml chlorpromazine in the right orbit, and 0.1 ml of saline in the left orbit as a control. Rats were euthanized, perfused, and postfixed at 1 to 2 weeks after injection. Exenterated orbital tissue was sectioned for histologic staining. Slides were reviewed by a masked ocular pathologist who evaluated the level of orbital inflammation. RESULTS: Histopathology demonstrated foci of granulomatous inflammation in the orbit of the patient and similar inflammation in the rat orbits injected with retrobulbar alcohol. In the chlorpromazine group, only 1 rat demonstrated small foci of inflammation, while the control orbits injected with saline showed no inflammation. On blinded qualitative analysis, the orbits receiving retrobulbar alcohol had greater inflammation than the orbits receiving either saline or chlorpromazine. CONCLUSIONS: Our findings in this preclinical pilot study suggest that retrobulbar alcohol injections incite significant orbital inflammation, whereas retrobulbar chlorpromazine induces little or no inflammation. This potential inflammatory response should be considered when selecting an agent for pain management, particularly if future orbital surgery is anticipated.

Prostaglandin-Associated Periorbital Lipodystrophy in Cosmetic Eyelid Surgery: A Novel Cause of Facial Asymmetry.

A 70-year-old woman presented to our practice with profound ptosis of the left upper eyelid and notable asymmetry of the periocular area. On examination, she was noted to have significant atrophy of the periocular tissues on the left side, with lower eyelid retraction. These features were present but less severe on the right side. Upon further questioning, she stated that she had cataract surgery on the left side that was complicated by a high intraocular pressure and required subsequent secondary surgery. She had taken a prostaglandin eyedrop for many months after her cataract surgery to keep the eye pressure low. Recently, a newly recognized adverse effect of prostaglandin eyedrops has been described in the ophthalmic literature in which patients develop periorbital lipodystrophy. This case emphasizes that this may occur unilaterally in patients taking the eyedrop in only one eye, and should be recognized prior to considering functional and aesthetic surgery of the periocular area.

Amblyaudia: Review of Pathophysiology, Clinical Presentation, and Treatment of a New Diagnosis.

OBJECTIVE: Similar to amblyopia in the visual system, "amblyaudia" is a term used to describe persistent hearing difficulty experienced by individuals with a history of asymmetric hearing loss (AHL) during a critical window of brain development. Few clinical reports have described this phenomenon and its consequent effects on central auditory processing. We aim to (1) define the concept of amblyaudia and (2) review contemporary research on its pathophysiology and emerging clinical relevance. DATA SOURCES: PubMed, Embase, and Cochrane databases. REVIEW METHODS: A systematic literature search was performed with combinations of search terms: "amblyaudia," "conductive hearing loss," "sensorineural hearing loss," "asymmetric," "pediatric," "auditory deprivation," and "auditory development." Relevant articles were considered for inclusion, including basic and clinical studies, case series, and major reviews. CONCLUSIONS: During critical periods of infant brain development, imbalanced auditory input associated with AHL may lead to abnormalities in binaural processing. Patients with amblyaudia can demonstrate long-term deficits in auditory perception even with correction or resolution of AHL. The greatest impact is in sound localization and hearing in noisy environments, both of which rely on bilateral auditory cues. Diagnosis and quantification of amblyaudia remain controversial and poorly defined. Prevention of amblyaudia may be possible through early identification and timely management of reversible causes of AHL. IMPLICATIONS FOR PRACTICE: Otolaryngologists, audiologists, and pediatricians should be aware of emerging data supporting amblyaudia as a diagnostic entity and be cognizant of the potential for lasting consequences of AHL. Prevention of long-term auditory deficits may be possible through rapid identification and correction.

Local Recurrence and Ocular Adnexal Complications Following Electronic Surface Brachytherapy for Basal Cell Carcinoma of the Lower Eyelid.

IMPORTANCE: Various treatment options exist for nonmelanoma skin cancer (NMSC), including topical agents, surgery, or definitive or adjuvant radiation therapy. Recently, electronic surface brachytherapy (ESB) has been described as a noninvasive option for NMSC. We report a case of local recurrence of basal cell carcinoma (BCC) and ocular complications following ESB to the lower eyelid. OBSERVATIONS: A man in his 60s presented with a recurrent BCC within the radiation field 10 months after undergoing ESB for a biopsy-proven BCC. In addition to the recurrence, he had contracture of the conjunctiva in the socket of his previously enucleated eye, as well as lower eyelid ectropion, resulting in displacement and loss of retention of his ocular prosthesis. CONCLUSIONS AND RELEVANCE: Electronic surface brachytherapy should be used with caution, particularly in the periocular region because the late effects of hypofractionated radiation may cause ocular and orbital complications. To our knowledge, this is the first reported case of ocular complications with this modality. This case highlights a local recurrence following use of this new treatment modality, suggesting further investigation is warranted to determine the safety and efficacy of ESB.

Oral methylphenidate for the treatment of refractory facial dystonias.

Oral methylphenidate (Ritalin, Novartis) has been reported to alleviate symptoms of benign essential blepharospasm in an off-label application. This series presents 3 patients with refractory periorbital and facial dystonias, including blepharospasm, apraxia of eyelid opening, and oromandibular dystonia unresponsive to standard treatments who experienced a response to oral methylphenidate therapy. While the mechanisms for facial dystonias have not been elucidated, there is evidence to suggest that they are on the spectrum with Parkinson disease. Given the role of dopamine loss in the pathogenesis of Parkinson, the authors' speculate that methylphenidate may be acting on the pathway directly involved in facial dystonias. To the authors' knowledge, this is the first report of a case of successful treatment of blepharospasm refractory to upper eyelid myectomy with methylphenidate monotherapy.

Confidence of ophthalmology residents in obtaining informed consent.

UNLABELLED: Ophthalmology residents often obtain informed consent for common procedures. In this study, we set out to determine the confidence levels among ophthalmology residents who obtain informed consent. An anonymous online survey was distributed to United States ophthalmology residents across the country. Ninety-five residents participated, evenly distributed geographically and by postgraduate year (PGY). Residents were frequently obtaining consent for procedures despite not being comfortable doing so. Only 18% of residents reported that they always felt comfortable with the informed consent process. Comfort level increased significantly with PGY (P < .001) and prior training in informed consent (P = .032). Of the residents surveyed, 76% indicated a desire for more formal training in the consent process. Most residents would welcome an informed-consent formal training curriculum, which would address 5 of the 6 Accreditation Council for Graduate Medical Education core competencies and meet resident milestones in the Next Accreditation System.

Alveolar rhabdomyosarcoma masquerading as embryonal subtype: the value of modern molecular diagnostic testing.

A 3-year-old child presented with a history of conjunctivitis in her OS. She had hyperglobus of the OS and a palpable mass in the left inferior orbit. An urgent MRI revealed an enhancing mass in the left orbit. The patient underwent an incisional biopsy with pathologic assessment most consistent with embryonal rhabdomyosarcoma. However, subsequent molecular genetic testing of the biopsy specimen was positive for the PAX3/PAX7-FKHR chimeric gene, indicating the tumor was actually an alveolar rhabdomyosarcoma. The patient received a more intensive chemotherapy regimen and also was treated with proton-beam radiotherapy. After chemotherapy and proton irradiation, the patient's tumor shrank considerably, and she remained in remission at over 3 years of follow up. This patient illustrates the new tools at the disposal of the orbital specialist including molecular genetic testing and proton-beam irradiation to diagnose and treat orbital rhabdomyosarcoma.

Risk of retinal tear or detachment with oral fluoroquinolone use: a cohort study.

PURPOSE: The aim of this study is to determine if oral fluoroquinolone exposure is associated with an increased hazard for having a retinal tear or detachment. METHODS: A retrospective cohort study was performed using individuals who met inclusion criteria from The Health Improvement Network database. Cohorts were created for individuals who had a prescription written for either an oral fluoroquinolone or an oral ß-lactam antibiotic (comparison group). Subjects were excluded if they had a previous diagnosis of a retinal tear or detachment (hereafter retinal break (RB)), or a procedure code to treat an RB, where in the practice for less than 365 days, had a previous prescription for either antibiotic within 365 days of the index date or had intraocular surgery or a diagnosis of endophthalmitis within 90 days prior to the antibiotic prescription. Covariates of interest were age, gender, diabetes, and year of index. The primary outcome measure of interest was the hazard ratio (HR) of undergoing a procedure to treat an RB within 7, 30, 90, or 365 days after exposure to an oral fluoroquinolone prescription versus an oral ß-lactam prescription. RESULTS: After exclusions, 6,604,423 prescriptions (290,393 fluoroquinolone; 6,314,030 ß-lactam) from 3,413,498 patients (247,073 fluoroquinolone; 3,303,641 ß-lactam) and 2685 RB procedures were eligible for analysis (661 retinal tears and 2024 retinal detachments). For fluoroquinolones, 0, 1, 5, and 23 RBs occurred at the 7-, 30-, 90-, and 365-day time points, respectively. For ß-lactam prescriptions, 7, 28, 87, and 373 RBs occurred at the 7-, 30-, 90-, and 365-day time points, respectively. Because of zero events occurring in the fluoroquinolone cohort during the 7-day observation period, an unadjusted or an adjusted HR (and subsequent p-value or confidence intervals) was unable to be calculated. Univariate and multivariate analyses demonstrated that fluoroquinolones were not significantly associated with RB in the 30-, 90-, or 365-day observation periods (30-day HR = 0.78, p = 0.80, 95%CI: 0.11, 5.71; 90-day HR = 1.25, p = 0.63, 95%CI: 0.51, 3.08; and 365-day HR = 1.35, p = 0.16, 95%CI: 0.89, 2.06). CONCLUSIONS: Our results do not support an association between oral fluoroquinolone use and subsequent procedures to treat an RB.

Orbital lymphoma in the setting of idiopathic CD4+ lymphocytopenia (HIV-negative AIDS).

A 43-year-old Asian man with idiopathic CD4+ lymphocytopenia (human immunodeficiency virus [HIV]-negative acquired immunodeficiency syndrome [AIDS]) noted blurred vision OD. Visual acuity was 20/30 OD and 20/15 OS. The right eye showed features of axial proptosis (2 mm), blepharoptosis, upgaze restriction, conjunctival chemosis, color desaturation, and choroidal folds. The OS was unremarkable. There was no lymphadenopathy. Orbital MRI showed a well-circumscribed mass indenting the globe. Excision revealed diffuse large-B-cell lymphoma. Systemic evaluation was negative and adjuvant external beam radiotherapy to the right orbit was performed. Idiopathic CD4+ lymphocytopenia is a rare hematologic condition characterized by depletion of CD4+ T cells in HIV-negative patients. This condition closely resembles AIDS but HIV serology is negative. Similar to AIDS, patients are at risk for opportunistic infections and neoplasia, including systemic lymphoma. This is the first case, to the authors' knowledge, of orbital lymphoma with idiopathic CD4+ lymphocytopenia.

Idiopathic orbital inflammation leading to unilateral blindness over a 2-day presentation in a child.

An 8-year-old boy developed vision loss to no light perception on the left side over a 2-day period. He initially presented with unilateral eyelid swelling, which progressed to bilateral edema and an eventual left-sided orbital apex syndrome. Orbital imaging revealed enlarged extraocular muscles, and biopsy confirmed idiopathic orbital inflammation. Despite subsequent orbital decompression, high-dose steroids, and additional steroid-sparing therapy, he did not regain vision after 9 months of follow up.
