Clinical characteristics and outcomes of orbital fractures: a sex-based cohort analysis.

Purpose: This study aims to identify clinical similarities and differences between males and females presenting with orbital fracture.

Methods: Patient charts of adult orbital fracture cases diagnosed via computed tomography and referred by a level 1 trauma center to the McGill University Health Centre between August 2015 to January 2018 were examined and analyzed. Clinical parameters included age, sex, mechanism of injury, morphology of orbital fracture, symptoms and examination features, and rates of ocular pathology.

Unintended placement of intraocular lens haptics in the sulcus and its association with posterior capsular opacification in pseudophakic post-mortem eyes.

Objective: To assess the prevalence of unintended placement of intraocular lens (IOL) haptics in the sulcus and its association with posterior capsular opacification (PCO).

Design: Cross-sectional study.

Participants: 428 post-mortem pseudophakic human eyes.

Inadvertent Orbital Mitomycin C Injection as a Cause of Ptosis and Ophthalmoplegia from Orbital Necrosis.

Mitomycin C is an alkylating agent with the ability to suppress fibroblast proliferation and activity, making it a powerful antifibrotic. It has therefore become popular in glaucoma filtering surgeries, used both intraoperatively during bleb formation and postoperatively as an adjunct to bleb needling. This report presents a rare but serious risk of bleb needling with Mitomycin C at the slit lamp, where inadvertent movement of the patient resulted in an orbital injection.

Objective analysis of capsulorrhexis factors and posterior capsular opacification in 420 postmortem eyes.

Objective: To evaluate the capsulorrhexis structure in postmortem eyes and determine factors associated with posterior capsular opacification (PCO).

Design: Experimental study.

Participants: Postmortem pseudophakic human eyes (n = 420).

THE ABILITY OF ARTIFICIAL INTELLIGENCE CHATBOTS ChatGPT AND GOOGLE BARD TO ACCURATELY CONVEY PREOPERATIVE INFORMATION FOR PATIENTS UNDERGOING OPHTHALMIC SURGERIES.

Introduction: To determine whether the two popular artificial intelligence chatbots, ChatGPT and Bard, can provide high-quality information concerning procedure description, risks, benefits, and alternatives of various ophthalmic surgeries.

Methods: ChatGPT and Bard were prompted with questions pertaining to the description, potential risks, benefits, alternatives, and implications of not proceeding with various surgeries in different subspecialties of ophthalmology. Six common ophthalmic procedures were included in the authors' analysis.

Clinical and anatomic correlates of objectively measured zonular dehiscence in 427 postmortem pseudophakic eyes.

Objective: This study aims to objectively measure the degree of zonular dehiscence in postmortem eyes and to assess for clinical and anatomic correlates.

Design: Cross-sectional study.

Materials: Four hundred and twenty-seven postmortem pseudophakic human eyes.

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.

Clinical correlations of extraocular motility limitation pattern in orbital fracture cases: a retrospective cohort study in a level 1 trauma centre.

Purpose: Ocular pathology (OP) following orbital fracture can vary vastly in complexity and severity. Extra-ocular motility (EOM) limitations are frequently present in orbital trauma cases, with patterns of duction limitations being symmetrical or asymmetrical. The aim of this study was to identify if there was any association between increased OP following orbital fracture cases based on the pattern of EOM deficits.

A technique for excisional optic nerve biopsy.

Purpose: To describe a transconjunctival technique for full-thickness (excisional) optic nerve biopsy.

Method: A medial transconjunctival approach to the optic nerve with disinsertion of the medial rectus is used. A small right-angle Mixter forcep is used to clamp the optic nerve far posteriorly, and then a microscalpel is directed metal-on-metal to cut the posterior optic nerve.

Significance of subconjunctival hemorrhage in predicting ocular pathology for patients with orbital fracture.

Objective: Subconjunctival hemorrhage (SCH) is a common presentation in patients with orbital trauma and often warrants investigation of underlying ocular pathology. Our study aims to assess the significance of SCH severity, graded in a spatial 0-360° manner, as a predictor for ocular pathology in patients with orbital fracture.

Design: Retrospective chart review.

Primary care assessment of orbital trauma at a level 1 trauma centre.

Objective: With increasing constraints on our publicly funded health care system, appropriate triage of trauma patients is becoming pivotal, making the primary care assessment (PCA) invaluable. Our study aims to compare the initial assessment of patients with orbital fractures with that conducted by the ophthalmology service.

Design: Retrospective chart review.

Unilateral upper eyelid eversion and kink associated with epidemic keratoconjunctivitis.

Purpose: Upper lid eversion in adults from non-cicatricial causes is rare. We report a case of upper eyelid eversion secondary to epidemic keratoconjunctivitis (EKC).

Observations: A 37 year-old female presented with unilateral upper lid eversion.

Quality of life considerations in uveal melanoma patients: a systematic review.

Objective: The aim of this study is to examine the quality of life (QOL) outcomes of patients undergoing different uveal melanoma (UM) treatments and to appraise the literature on the topic.

Design And Participants: A systematic review was conducted to address the study objective. Patients undergoing UM treatment with or without metastasis were eligible for inclusion in this review.

Incidence and outcomes of retrobulbar hematoma diagnosed by computed tomography in cases of orbital fracture.

Objective: Retrobulbar hemorrhage (RBH) is a potentially sight-threatening complication of orbital fractures causing an orbital compartment syndrome (OCS). RBH causing OCS is regarded as a clinical diagnosis when evidence of optic nerve compression is found. Nonetheless, many patients with facial trauma will have received imaging by computed tomography (CT) on which there is documented RBH, with or without signs of OCS.

Cavernous sinus syndrome associated with metastatic colorectal cancer and perineural spread along the trigeminal nerve.

Purpose: We report the case of a patient with cavernous sinus syndrome associated with biopsy-confirmed metastasis from colorectal cancer.

Observations: A patient known for laryngeal carcinoma and metastatic colorectal carcinoma presented with symptoms of left trigeminal neuralgia and progressive, near-complete ophthalmoplegia. Magnetic resonance imaging (MRI) revealed a mass in the left cavernous sinus, extending into Meckel's cave with perineural spread along the mandibular branch of the left trigeminal nerve.

Radiology Exposure in the Undergraduate Curriculum: A Medical Student Perspective on Quality and Opportunities for Positive Change.

Purpose: This article is a continuation of a qualitative study designed to explore how radiology exposures can impact medical student opinions and perceptions of radiology and radiologists. We focused on: 1) conducting a radiology exposure inventory from the perspective of the medical student; 2) student evaluation of the quality of the radiology exposures and suggestions for positive change; and 3) development of a framework to address the needs of medical students as it relates to radiology education in the undergraduate medical curriculum.

Methods: Research methodology and design for this qualitative study were described in detail in a previous article by Visscher et al [1].
