Ahsen Hussain, Navdeep Nijhawan, Dan DeAngelis, James Oestreicher
Computer-assisted surgery (CAS) plays a prominent role in certain surgical disciplines. We investigated the current perceptions and use of this technology for orbital surgery. An online survey was emailed to members of the American Society of Ophthalmic Plastic and Reconstructive Surgery, Canadian Society of Oculoplastic Surgery, and British Oculoplastic Surgery Society. Respondents were asked to describe their practice type and seniority, their frequency of orbital surgery, experience, use, and accessibility of CAS, and their opinion on the technology...

Saagar A Pandit, Lora R Dagi Glass
PURPOSE: To better understand the nature of periocular dermatitis (PD) patient presentation, treatment, time-to-cure, and referral pattern for allergy testing in an ophthalmic academic center. METHODS: A retrospective chart review of 344 patients diagnosed with PD between January 1, 2000 and November 30, 2016 at the Edward S. Harkness Eye Institute was performed. Eighty patients were eligible for the study. The primary endpoint was the time-to-cure. Cox proportional hazards regression was performed to assess if there was a significant difference between time-to-cure in patients treated with: 1) combination topical steroid/antibiotic (n = 6) vs...

Desmoplasia is the formation of a dense collagenous stroma around a neoplasm. It occurs in a variety of malignancies including squamous cell carcinoma (SCC). While desmoplasia is uncommonly seen in cutaneous SCC, it is an independent risk factor for recurrence and metastasis. We report a case series of desmoplastic SCC in the periorbital region. Seven cases were identified: the median age was 68, four were men. The mean follow-up was 48 months. Two patients (29%) had aggressive local recurrence: one required salvage surgery including orbital exenteration, parotidectomy, and neck dissection to excise involved parotid and cervical lymph nodes; the other required repeat excision and adjuvant radiotherapy...

PURPOSE: Multiple myeloma is an insidious haematological malignancy characterised by monoclonal proliferation of plasma cells in the bone marrow. Extramedullary plasmacytoma is a rare manifestation of multiple myeloma and usually occurs in the upper respiratory tract. Orbital involvement is particularly uncommon, but may be associated with devastating visual impairment and poor clinical outcomes. Therefore, this article aims to highlight the need for multidisciplinary management of orbital extramedullary plasmacytoma...

We report the first case of fatal myocarditis presenting as bilateral ptosis in a patient on combination therapy with pembrolizumab and epacadostat. An 83 year-old man with stage III high-grade urothelial carcinoma presented with acute onset droopy eyelids one month after starting pembrolizumab and epacadostat. Exam showed myogenic ptosis and ophthalmoplegia. He was later found to have acute myocarditis with complete heart block and subsequently passed away. Pembrolizumab in combination with epacadostat can induce a potentially fatal myocarditis...

Amun Sachdev, Declan Costello, Simon Madge
In ophthalmology, there have been few reports of botulinum toxin type-A (BTX-A) injection into the lacrimal gland to treat epiphora. In ENT, adductor and abductor (ABSD) spasmodic dysphonia are often treated with BTX-A injections into the respective overacting vocal cord muscles. We describe a 53-year old male with Parkinson's disease who did not respond to BTX-A injections to either the lacrimal gland, for epiphora secondary to Parkinsonian-related blink lagophthalmos, or posterior cricoarytenoid (PCA) muscles for ABSD...

PURPOSE: Bleomycin sclerotherapy has been shown to be a viable treatment for lymphatic malformations. However, its use for these lesions confined to the orbit is becoming increasingly documented in the literature. In this study, we summarize the clinical manifestations and outcomes observed following percutaneous bleomycin sclerotherapy for orbital lymphatic malformation. METHODS: A 5-year retrospective chart review of patients with clinical, radiographic, and/or biopsy-confirmed diagnoses of orbital lymphatic malformation that received bleomycin sclerotherapy was conducted at the Emory Hospital and Clinics...

Dog bites result in a diverse range of injuries and complications in the periocular region, particularly in school aged children. It is therefore incumbent on the oculoplastic surgeon to be well versed in both acute and long-term management. The intent of this review is to provide a systematic evaluation of the epidemiology, principles of dog bite wound care, and specific considerations related to common patterns of ophthalmic injury. Review of clinical literature from 1976 to 2014. The majority of periocular injuries result from seemingly benign interactions between young children and familiar dogs...

Mariel Angelou A Parulan, Gangadhara Sundar, Jeffrey Hy Lum, Umashankar Ramachandran
We report a case of a 49-year old East-Asian female who presented with delayed onset granuloma formation at the right medial lower eyelid area. The clinical and radiologic presentation with pathologic correlation following synthetic hyaluronic acid filler injection and its management are described along with a review of literature following dermal-filler injections types. Dermal-filler-related granuloma formation should be included in the differential diagnoses of periorbital inflammatory and mass lesions. It is recommended that clinicians who perform this procedure should discuss these risks and possible late complications with patients and provide them with the relevant product information of the injected filler for appropriate management should such early or late complications occur...

Traditionally, posterior eyelid surgical approaches such as Müller's muscle-conjunctival resection (MMCR) have been utilised with great success for mild cases of ptosis, with external levator approaches having been used for more severe cases of ptosis. We present a new technique which we label closed posterior levator advancement (CPLA) for the correction of all grades of ptosis. This article is a retrospective cohort study reviewing patients with mild, moderate, and severe ptosis over a 6-year period, treated by a single surgeon using CPLA...

We report the case of an anterior orbital tumor in a young woman that enlarged during pregnancy. The mass was excised and found to be a spindle cell tumor with immunohistochemical reactivity consistent with a solitary fibrous tumor, a rare entity in the spectrum of fibroblastic mesenchymal tumors. The tumor was strongly positive for the progesterone receptor, consistent with its clinical growth during the antenatal and postnatal periods. To our knowledge, a primary orbital tumor with these characteristics has rarely been reported in the literature...

The aim of the review is to describe the different techniques and materials available to reconstruct the tarsoconjunctival layer of the eyelid; to analyze their indications, advantages, and disadvantages. We searched the Cochrane, PubMed, and Ovid MEDLINE databases for English articles published between January 1990 and January 2017 using variations of the following key words: "posterior lamella," "eyelid reconstruction," "tarsoconjunctival," "flap," and "graft." Two reviewers checked the abstracts of the articles found to eliminate redundant or not relevant articles...

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...

Jacqueline M Jacobs, Eva L Chou, Nathan T Tagg
Silent sinus syndrome (SSS) is a rare disorder involving bony remodeling of the maxillary sinuses, including collapse of the orbital floor. It is typically unilateral and seen in the setting of chronic maxillary sinusitis. Patients present with enophthalmos and hypoglobus occasionally accompanied by diplopia. The condition is generally diagnosed with CT imaging and treated surgically. While SSS is most often reported as very slowly progressive, we report a patient with evidence of significant remodeling of the maxillary sinus over a period of 5...
