Comparison of Endophthalmitis Rates after Alcohol-Based Chlorhexidine and Povidone-Iodine Antisepsis for Intravitreal Injections.

Objective: Intravitreal injections (IVIs) are the most frequently performed intraocular procedure in Canada. Povidone-iodine (PI) is the current gold standard for antisepsis for IVI and is widely used; chlorhexidine (CH) is a possible alternative antiseptic agent. This study aims to compare rates of endophthalmitis after IVI with 0.

Epidemiology of ocular emergencies in a large Canadian eye centre.

Objective: The Eye Institute of Alberta Emergency Eye Clinic (EIA EEC) is a tertiary eye care centre that provides emergency eye services to a population of more than 1 million. The purpose of this study was to describe the epidemiology of ocular emergencies at the EIA EEC.

Design: Prospective epidemiologic study based on secondary use of patient data.

Quality improvement strategies for diabetes care: Effects on outcomes for adults living with diabetes.

Background: There is a large body of evidence evaluating quality improvement (QI) programmes to improve care for adults living with diabetes. These programmes are often comprised of multiple QI strategies, which may be implemented in various combinations. Decision-makers planning to implement or evaluate a new QI programme, or both, need reliable evidence on the relative effectiveness of different QI strategies (individually and in combination) for different patient populations.

Design: Prospective cohort study of patients who underwent DMEK surgery between January 1, 2020, and December 31, 2020.

Participants: All patients receiving a DMEK transplant during the study period in Edmonton.

Incidence of steroid response in microinvasive glaucoma surgery with trabecular microbypass stent and ab interno trabeculectomy.

Objective: To determine the incidence and risk factors for steroid response in patients undergoing combined phacoemulsification cataract extraction (PCE) and microinvasive glaucoma surgery with either trabecular microbypass stent implantation (iStent) or ab interno trabeculectomy (Trabectome).

Design: Retrospective, noncomparative, single-institutional observational chart review.

Participants: Consecutive patients with open-angle glaucoma who underwent PCE with iStent or Trabectome with 3 months of follow-up.

Aircraft Cabin Pressurization and Concern for Non-Arteritic Anterior Ischemic Optic Neuropathy.

Cabin pressurization is the process by which aircraft maintain a comfortable and safe environment for passengers flying at high altitudes. At high altitudes, most patients can tolerate changes in pressurization; however, passengers at high risk of hypoxia may experience ischemic events. The purpose of this study was to evaluate variations in pressurization of commercial aircraft at cruising altitude and describe its relevance in relation to patients with non-arteritic anterior ischemic optic neuropathy (NAION).

OUTCOMES OF VITRECTOMY IN TERSON SYNDROME: A Multicenter Canadian Perspective.

Purpose: To characterize the presentation of Terson syndrome, the occurrence of a vitreous hemorrhage in association with intracranial hemorrhage, and report on the outcomes of vitrectomy at two major centers in Canada.

Methods: Retrospective chart review of consecutive patients with Terson syndrome undergoing vitrectomy by retina specialists over the last 10 years. Primary outcome was the change in best-corrected visual acuity (BCVA) at 3 months from baseline.

Evaluation of ophthalmology clerkships across teaching sites at the University of British Columbia.

Objective: Clerkship at the University of British Columbia (UBC) Medical School encompasses a variety of models: traditional rotation-based clerkship; distributed rotation-based clerkship at sites across the province; and a longitudinal integrated community clerkship. The purpose of this study was to: (i) Evaluate the undergraduate ophthalmology clerkship experience at UBC to compare outcomes and experiences across the various sites and models; and (ii) Apply educational theories to evaluation outcomes in order to improve curriculum design for clerkship programs.

Design: Cross-sectional evaluation of the ophthalmology clerkship program at UBC.

K-RIM (Corneal Rim) Angle Surgery Training Model.

Purpose: To develop an angle surgery training model for training an array of microincisional glaucoma surgery (MIGS) procedures.

Methods: We describe a method for preparing an angle surgery training model using human cadaveric corneoscleral rims. The model provides realistic tactile tissue simulation and excellent angle visualization requiring bimanual technique.

Efficacy and safety of ab interno trabeculectomy in juvenile open-angle glaucoma.

Objective: To determine the efficacy and safety of ab interno trabeculectomy with Trabectome in juvenile open-angle glaucoma (JOAG) patients.

Design: Prospective cohort study.

Methods: Evaluation of the 12-month results of 2 patient groups receiving ab interno trabeculectomy: group 1, eyes with no prior incisional surgery; group 2, eyes that had prior incisional cataract or glaucoma surgery.

Cadaver corneoscleral model for angle surgery training.

Purpose: To assess a new training model (Tackdriver) for new-generation microinvasive glaucoma surgeries (MIGS).

Setting: Resident training centers in Canada.

Design: Evaluation of technology.

Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) in Postpenetrating Keratoplasty Steroid-induced Glaucoma: A Case Report.

Glaucoma following penetrating keratoplasty (PKP) remains the leading cause of blindness following PKP. Patients with post-PKP glaucoma can be managed medically and surgically. Evidence studying glaucoma surgical techniques following PKP is limited, but suggests the possibility for high-risk complications, including graft failure.

What have we learned about exfoliation syndrome since its discovery by John Lindberg 100 years ago?

Exfoliation syndrome (XFS) is a systemic disease with significant ocular manifestations, including glaucoma and cataract. The disease impacts close to 70 million people globally and is now recognised as the most common identifiable cause of open-angle glaucoma. Since the discovery of XFS 100 years ago by Dr John G.

Cataract and Glaucoma Surgery: Endoscopic Cyclophotocoagulation versus Trabeculectomy.

Purpose: To compare the efficacy and safety of endoscopic cyclophotocoagulation (ECP) versus trabeculectomy with mitomycin C (trab) in combination with cataract surgery.

Materials And Methods: We evaluated the 6-month results of patients undergoing phacoemulsification (phaco) with either ECP or trab. The primary outcome was mean intraocular pressure (IOP) at 6 months; secondary outcomes were change in glaucoma medications, visual acuity, intraocular inflammation, and postoperative complications.

Improving patient identification in an ophthalmology clinic using name alerts.

Objective: To develop a standardized process for reviewing daily patient lists and identifying potential risks of misidentification. Our goal was to develop a proactive approach to identify and eliminate risks of patient misidentification.

Methods: Assessment of current patient identification practices took place over a period of 4 weeks.

The application of a "6S Lean" initiative to improve workflow for emergency eye examination rooms.

Background: Ophthalmology residents on call at the Royal Alexandra Hospital identified workplace disorganization and lack of standardization in emergency eye examination rooms as an impediment to efficient patient treatment.

Objective: The aim of the study was to use the "6S Lean" model to improve workflow in eye examination rooms at the Royal Alexandra Hospital.

Methods: With the assistance of quality improvement consultants, the "6S Lean" model was applied to the current operation of the emergency eye clinic examination rooms.

Mandibular advancement appliances for the treatment of paediatric obstructive sleep apnea: a systematic review.

Objective: To evaluate the effectiveness of mandibular advancement appliances (MAAs) for treatment of pediatric obstructive sleep apnea (OSA).

Methods: Several electronic databases (The Cochrane Database, EMBASE, Healthstar, MEDLINE, PubMed) were systematically searched, as well as a limited grey literature (Google Scholar) and manual searches. A health sciences librarian helped with the selection of Medical Subject Headings (MeSH), key words, and combinations of key words with truncations to account for any differences in controlled terminology in the different databases.
