The Isabel Differential Diagnosis Generator for Orbital Diagnosis.

Purpose: The Isabel differential diagnosis generator is one of the most widely known electronic diagnosis decision support tools. The authors prospectively evaluated the utility of Isabel for orbital disease differential diagnosis.

Methods: The terms "proptosis," "lid retraction," "orbit inflammation," "orbit tumour," "orbit tumor, infiltrative" and "orbital tumor, well-circumscribed" were separately input into Isabel and the results were tabulated.

Implantation of a Coronary Stent Into the Canaliculus of a Human Cadaver: A Pilot Study.

Purpose: To evaluate the possibility of implanting a drug-eluting coronary stent into the canaliculus of a human cadaver.

Methods: The punctum and canaliculus of an embalmed human cadaver were identified and dilated using a punctum dilator and Bowman probes. At this stage, the integrity of the lacrimal drainage system was assessed by dacryoendoscopy.

Intravascular Papillary Endothelial Hyperplasia as a Cause of Reversible Vision Loss.

Intravascular papillary endothelial hyperplasia (IPEH) is a benign vascular lesion that is formally diagnosed on histopathology. IPEH seldom presents in periocular tissues and is even less commonly seen deep within the orbit. As with cavernous hemangioma, this lesion tends to distort surrounding structures and can cause a significant mass effect in the orbit.

Seven-Year Follow-Up of a Patient With a Retained Needlefish Jaw Fragment Abutting Against His Left Internal Carotid Artery.

A 51-year-old man presented to the ophthalmology service with binocular diplopia and facial numbness. The patient was returning from a trip to Mexico. He reported having been hit in the left periocular region by a fish while swimming.

Personal protective equipment (PPE) during the COVID-19 pandemic for oculofacial plastic and orbital surgery.

: To review the current literature on Coronavirus Disease 2019 (COVID-19) virology and transmission; to present a decision tree for risk stratifying oculofacial plastic and orbital surgeries; and to generate personal protective equipment (PPE) recommendations by risk category.: A comprehensive literature review on COVID-19 was conducted. A two-stage modified Delphi technique involving 18 oculofacial plastic and orbital surgeons across Canada was used to determine consensus risk-stratification criteria and PPE recommendations for surgeries performed in the North American context.

Guidelines for vismodegib in the management of periocular basal cell carcinoma.

Objective: The management of advanced basal cell carcinoma (BCC) in the periocular region remains a clinical challenge. Vismodegib (Erivedge) has been approved in 2013 by Health Canada for adult patients with "histologically confirmed metastatic BCC or locally advanced BCC inappropriate for surgery or radiation." An expert consensus was sought to create a standardised approach in the use of this novel treatment.

Regression of Sebaceous Carcinoma of the Eyelid after a Small Incisional Biopsy: Report of Two Cases.

Purpose: To report 2 cases of regression of sebaceous carcinoma of the eyelid after a small incisional biopsy.

Methods: Clinical, imaging, and histopathological findings are presented, with a literature review on regressing ocular tumors.

Results: Our first patient was a 79-year-old man who presented with a 10-month history of progressive left upper eyelid ptosis caused by an eyelid tumor with orbital involvement and confirmed on magnetic resonance imaging.

Neural network and logistic regression diagnostic prediction models for giant cell arteritis: development and validation.

Purpose: To develop and validate neural network (NN) vs logistic regression (LR) diagnostic prediction models in patients with suspected giant cell arteritis (GCA). Design: Multicenter retrospective chart review.

Methods: An audit of consecutive patients undergoing temporal artery biopsy (TABx) for suspected GCA was conducted at 14 international medical centers.

Local anesthesia and anxiolytic techniques for oculoplastic surgery.

This study discusses local anesthetic agents, administration techniques, ancillary considerations, and safety precautions for oculoplastic surgery including eyelid, lacrimal, orbital, and temporal artery biopsy procedures. Methods for reducing patient apprehension and discomfort including systemic premedication, topical pre-anesthetic, visual, auditory and tactile distraction techniques, regional blocks, small gauge needles, warmed lidocaine, and buffered lidocaine are discussed.

Meta-analysis of randomized controlled trials in dacryocystorhinostomy with and without silicone intubation.

Objective: To determine the effect of bicanalicular silicone intubation (SI) on dacryocystorhinostomy (DCR) success rate in adult primary acquired nasolacrimal duct obstruction.

Design: Meta-analysis of randomized controlled trials (RCTs).

Methods: PubMed, Embase, Cochrane CENTRAL, Ovid Medline, Google Scholar, and grey literature search was performed from inception to June 2017.

Perceptions and use of computer-assisted surgery (CAS) in the orbit.

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.

Colletotrichum truncatum species complex: Treatment considerations and review of the literature for an unusual pathogen causing fungal keratitis and endophthalmitis.

We present a case of Colletotrichum truncatum species complex fungal keratitis and endophthalmitis in an 87-year-old immunocompetent male in whom oral triazole antifungals were contraindicated. The patient had recently returned from 4 months in Jamaica with a one month history of progressively increasing pain and inflammation in his left eye. Corneal samples grew a filamentous fungus and internal transcribed spacer sequencing polymerase chain reaction confirmed the presence of C.

Necrobiotic xanthogranuloma with predominant periorbital involvement.

We present an unusual variant of necrobiotic xanthogranuloma with periorbital involvement. Our patient had an unusually complicated course due to initial misdiagnosis and patient refusal to undergo treatment. We present her clinical course and review the literature on this rare lesion.
