Acute Vision Loss as an Ophthalmic Complication of Dental Procedures.

Acute vision loss has been previously described as a complication of dental procedures through a variety of mechanisms. The vision loss is typically transient, although permanent loss has been reported. Physicians, including ophthalmologists, typically lack formal education around dental procedures and may be uninformed about the risks to ocular or periocular structures as well as the types of complications that can arise.

Educational Impact Drives Feasibility of Implementing Daily Assessment in the Workplace.

Authors investigated the perspectives of stakeholders on feasibility elements of workplace-based assessments (WBA) with varying designs. In the transition to competency-based medical education, WBA are taking a more prominent role in assessment programs. However, the increased demand for WBA leads to new challenges for implementing suitable WBA tools with published validity evidence, while also being feasible and useful in practice.

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.

Correlation in Severity Between Glaucoma and Erectile Dysfunction.

Purpose: To examine the association between open-angle glaucoma and erectile dysfunction (ED), and investigate the correlation in severity between these 2 conditions.

Methods: Cross-sectional study with patient questionnaire and retrospective chart review. A total of 167 male patients over 40 years of age who attended ophthalmology clinic visits in Vancouver, British Columbia, Canada, participated in the study by providing written consent and responding to the survey.

Statin use and risk for cataract: a nested case-control study of 2 populations in Canada and the United States.

Background: In current literature the association between statin use and cataracts is inconsistent and controversial. We sought to further examine the effect of statin use on the risk of cataract and need for surgical intervention in 2 North American populations.

Methods: This retrospective nested case-control study derived data from the British Columbia (BC) Ministry of Health databases from 2000-2007 and the IMS LifeLink database from 2001-2011 to form 2 patient cohorts.

Association between phosphodiesterase-5 inhibitors and nonarteritic anterior ischemic optic neuropathy.

Background: Use of phosphodiesterase-5 (PDE-5) inhibitors has been reported to be a risk factor for development of nonarteritic anterior ischemic optic neuropathy (NAION) in males, based largely on a number of case reports. The objective of our study was to determine whether men who use this class of medications are more likely than a matched control group to develop NAION.

Methods: A pharmacoepidemiological nested case-control study was used to examine the above association in a health claims database of physician diagnoses and prescription medication dispensing.

Periocular mass lesions secondary to dermatologic fillers: report of 3 cases.

Objective: To describe findings in patients who received dermal fillers and later developed peri-ocular mass lesions.

Design: Retrospective case series.

Participants: Patients who presented with peri-ocular masses secondary to dermal filler use.

Optical coherence tomography-based measurement of drusen load predicts development of advanced age-related macular degeneration.

Purpose: To determine whether baseline drusen load, as measured using spectral-domain optical coherence tomography (SD OCT), is a useful predictor of development of advanced age-related macular degeneration (AMD).

Design: Retrospective cohort study.

Methods: setting: Academic clinical practice.

Trephination for canalicular obstruction: experience in 45 eyes.

Purpose: To evaluate efficacy of a trephination procedure for resolution of primary canalicular obstruction or obstruction secondary to failed dacryocystorhinostomy (DCR).

Methods: Retrospective review of patients in a single surgeon's practice who underwent trephination with Crawford tube insertion between 2001 and 2011, with a minimum follow-up period of 12 months. Indications for surgery included symptomatic patients either with primary canalicular obstruction or secondary obstruction after a failed DCR.

Association between glaucoma, glaucoma therapies, and erectile dysfunction.

Purpose: To examine the association between (1) glaucoma and erectile dysfunction (ED) and (2) topical β-blocker (BB) use and ED.

Methods: A comprehensive, province-wide database of physician visits and diagnoses and prescription drug dispensing was used to identify cases of ED (1380) and find corresponding controls (13,800). A conditional logistic regression model was used to estimate rate ratios for 2 main exposures: (1) diagnosis of glaucoma and (2) use of a prescription of a topical BB before the index date.
