Purpose: To assess the quality of hydroxychloroquine (HCQ)-induced retinopathy screening at a Canadian tertiary center, we concentrate on risk factor documentation within the electronic health record, in accordance with the 2016 AAO guidelines.
Methods: We performed a retrospective quality assessment study based on chart review of patients who underwent screening for HCQ-induced retinopathy at the Centre Hospitalier de l'Université de Montréal (CHUM) from 2016 to 2019. We evaluated four key risk factors for HCQ-induced retinopathy: daily dose, duration of use, renal disease, and tamoxifen use, using a three-tier grading system (ideal, adequate, inadequate) for documentation assessment.
Background: Evidence on the performance of Generative Pre-trained Transformer 4 (GPT-4), a large language model (LLM), in the ophthalmology question-answering domain is needed.
Methods: We tested GPT-4 on two 260-question multiple choice question sets from the Basic and Clinical Science Course (BCSC) Self-Assessment Program and the OphthoQuestions question banks. We compared the accuracy of GPT-4 models with varying temperatures (creativity setting) and evaluated their responses in a subset of questions.
Purpose: Foundation models are a novel type of artificial intelligence algorithms, in which models are pretrained at scale on unannotated data and fine-tuned for a myriad of downstream tasks, such as generating text. This study assessed the accuracy of ChatGPT, a large language model (LLM), in the ophthalmology question-answering space.
Design: Evaluation of diagnostic test or technology.
Background: Physical therapists (PTs) should know how to best treat patients with inflammatory arthritis.
Objective: To document interventions chosen by PTs for patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS) and whether choices follow evidence-based practice.
Methods: Licensed musculoskeletal PTs in Quebec, Canada responded to an online survey.
Background/objectives: To compare long-term outcomes of the Boston type 1 keratoprosthesis (KPro) with penetrating keratoplasty (PKP) in patients with a failed first PKP.
Subjects/methods: In this retrospective comparative case series, 48 eyes of 48 patients who underwent a second corneal replacement procedure after a first failed PKP at the Centre Hospitalier de l'Université de Montréal from 2008 to 2020 were included. Minimum follow-up duration was 5 years, and patients with keratoconus were excluded since such subjects are not candidates for KPro.
Article Synopsis
- The study aimed to determine how long patients with Boston type 1 keratoprosthesis (KPro) take to achieve their best-corrected visual acuity (BCVA) and what factors influence this time.
- After reviewing 137 eyes from 118 patients over an average of 5.49 years, it was found that most patients reached their BCVA within 3 to 6 months post-surgery.
- The presence of complications like postoperative glaucoma, retroprosthetic membrane (RPM), and endophthalmitis significantly delayed achieving BCVA, while factors such as age, gender, and previous surgeries showed no correlation.
We surveyed Canadian rheumatologists regarding beliefs about physical therapists' (PTs) ability to refer patients appropriately to rheumatologists and whether they would accept such referrals. Most (86.9%) believed that PTs can appropriately refer to rheumatologists.

Physiotherapists in Quebec answered a cross-sectional survey that was sent through licensing bodies and social media contacts. The respondents were asked which treatments they would use for a typical case of knee OA.

Methods: We sent a questionnaire to PTs in 2 Canadian provinces describing 4 case scenarios (new-onset rheumatoid arthritis [RA], knee osteoarthritis [OA], new-onset ankylosing spondylitis [AS], and low back pain [LBP]). Participants were asked to identify probable medical diagnoses and indicate their plan of action.
