#1
Stella Y Chung, Leon Rafailov, Roger E Turbin, Paul D Langer
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...

PURPOSE: To report a simple, highly effective technique of simultaneous transconjunctival repair of upper and lower eyelid retraction in patients with thyroid eye disease (TED). METHODS: A retrospective interventional case review was conducted on 22 eyes of 19 TED patients. The lower eyelid was recessed with placement of a tarsoconjunctival spacer graft harvested from the upper eyelid. The upper eyelid was then recessed through the conjunctival incision used to harvest the tarsal graft...

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...

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, describes a disease of poorly understood pathophysiology with a specific set of signs and symptoms including potentially irreversible and blinding visual loss. Optic nerve sheath fenestration (ONSF) is a well-described surgical treatment for patients with IIH and progressive visual loss despite maximally tolerated medical therapy. A number of optic nerve access procedures have been described including medial transconjunctival, superomedial lid crease, and lateral orbitotomy with and without bone takedown...

Adnexal and periocular involvement in Neisseria gonorrhoeae (NG) infection is rare. This report describes the case of a patient with a delayed diagnosis of gonococcal dacryoadenitis with contiguous conjunctivitis and corneal involvement. She underwent extensive inpatient laboratory and infectious workup but rapidly progressed to corneal perforation requiring emergent penetrating keratoplasty prior to a positive culture confirming the diagnosis. To date, this is the first reported case of ophthalmologic NG infection with associated conjunctivitis, dacryoadenitis, and corneal perforation...

A 51-year-old female underwent four upper zygomatic dental implants (ZI) and one upper and four lower conventional implants. Immediately postoperatively, the patient had pain and diplopia upon manual elevation of the edematous eyelid. Panoramic x-ray showed a malpositioned right upper ZI, requiring removal of the right upper ZI the following day. The patient had delayed referral to ophthalmology one month later for persistent diplopia. Computed tomography scan and magnetic resonance imaging demonstrated a right inferolateral fracture with fibrosis surrounding the inferior oblique muscle...

We report a case of myeloid sarcoma with multifocal skeletal involvement, including the greater wing of the sphenoid bone. A 23-month-old boy presented with left-sided proptosis and fevers, and was found to have an infiltrative mass involving the left sphenoid bone on orbital imaging. Full body imaging further demonstrated multiple bony lesions in the pelvis, thoracic and lumbar vertebrae, bilateral femura, and left humerus, and biopsies of the humerus were consistent with myeloid sarcoma. The patient was started on a standard chemotherapy regimen and is responding well...

Intradiploic epidermoid cysts are uncommon in the orbital walls and typically present with chronic headaches. We present the unusual presentation of a 46-year-old man where a long-standing intradiploic mass of the orbital roof led to acute onset of pain and mechanical ptosis. Computed tomography and magnetic resonance imaging revealed an intradiploic cystic mass within the orbital roof. The cystic mass was extirpated and histological examination confirmed the diagnosis of an epidermoid cyst. This case illustrates the potential of long-standing intradiploic epidermoid cysts in producing an acute presentation...

BACKGROUND: Endoscopic dacryocystorhinostomies (eDCRs) show patency rates between 81% and 94%. However, dacryocystorhinostomy (DCR) failure and the need for revision remain a significant challenge. One of the principal challenges in revision eDCR is the need to surgically identify the correct osteotomy site and maintain long-term patency in the setting of previously instrumented and potentially scarred tissue. At the same time, the surgeon must assume that the blood supply to the commonly described anterior and posteriorly pedicled flaps has been compromised...
