Objective: To describe the risk and nature of retinopathy of prematurity (ROP) in micro-premature infants (≤26 weeks' gestational age [GA]).
Methods: Retrospective analysis of prospectively collected data from infants born at 22-26 weeks' GA over a 5-year period.
Results: A total of 502 infants were identified, of whom 414 survived to discharge (82.
Purpose: To track operative phases of cataract surgery over a resident's training to measure action times and frequencies as a surrogate for competency and skill progression.
Design: An n = 1 panel study.
Methods: Cataract surgery video recordings performed by a single resident between 2021-2022 were collected.
Article Synopsis
- The study aimed to assess how accurately medical students can examine the fundus using either an unmodified iPhone X or a direct ophthalmoscope compared to a staff ophthalmologist's evaluations.
- Medical students conducted 230 retinal exams, with a higher failure rate in reporting the cup-to-disc ratio when using the iPhone X (81.2%) compared to the direct ophthalmoscope (30.1%).
- Overall, both the iPhone X and direct ophthalmoscope showed poor reliability against the staff ophthalmologist's findings, but the iPhone X was particularly less effective for optic disc visualization.
Purpose: To validate the Iris Glare, Appearance, and Photophobia (Iris GAP) questionnaire, a new symptom-based and appearance-based quality-of-life measure for patients with iris defects.
Setting: Single tertiary glaucoma clinic in Toronto, Ontario, Canada.
Design: Prospective cohort study.
Introduction: There are many barriers for patients with intermittent claudication (IC) to complete and maintain the supervised exercise therapy (SET) programs. SET combined with life-style counseling was, therefore, investigated.
Objective: This study aimed to report the experience of a single center where SET and life-style counseling targeting the modification of risk factors to treat IC, improved walking distance and quality of life.
Background: People who inject drugs (PWIDs) have sub-optimal HIV and HCV testing as the available testing services are inadequate in low and middle-income countries. We examined a model of Community-Led Testing (CLT) in Nepal, exploring the feasibility of HIV and HCV testing by trained lay service providers who had similar backgrounds to those of PWIDs. We also assessed the prevalence of HIV and HCV within this study population and the associated risk factors among PWIDs.

Multiple large international guidelines state that besides cardiovascular risk management, supervised exercise therapy (SET) should be offered to all patients with intermittent claudication. As described in this review, The Netherlands have already established a systemic rehabilitation program, ClaudicatioNet, where SET has been included and have shown positive outcomes.

Observations: We describe the surgical management of a 35-year-old man with a live intravitreal nematode in his left eye. A 23-gauge pars plana limited core vitrectomy was performed to release the nematode from the surrounding vitreous strands.
Central retinal artery occlusion (CRAO) is a devastating disease resulting in severe visual loss in most cases. It has no proven treatment, and a variety of management options used clinically all have dismal rate of success. We report outcome of treatment with local intra-arterial thrombolysis administered 2.

Design: Retrospective cohort study.
Participants: A total of 104 eyes that underwent combined phacoemulsification with either AGV (PhacoAGV; n = 57) or BGI (PhacoBGI; n = 47) implantation.
Objective: To compare the traditional teaching approach of binocular indirect ophthalmoscopy (BIO) to the EyeSI augmented reality (AR) BIO simulator.
Design: Prospective randomized control trial.
Participants: 28 post-graduate year one (PGY1) ophthalmology residents.
Background: The purpose of this study was to characterize beliefs and practice patterns for breast cancer reconstruction among physicians who treat patients with breast cancer, in order to delineate current clinical practice. This survey was administered prior to Cancer Care Ontario guideline publication.
Method: Survey questions addressed four domains: survival, delayed or obscured recurrence detection, delayed adjuvant therapy, and aesthetics.
Background And Purpose: The purpose of this study was to analyze the 30-day outcome after introduction of a rapid carotid endarterectomy (CEA) program. Reasons for delay in CEA and the incidence of early recurrence neurological symptoms were recorded.
Methods: This is a prospective population-based study of delays to CEA and 30-day outcome in patients with symptomatic carotid stenosis.
Background: A new method was evaluated where local changes in oxygen tension were induced in a tissue while being studied under a microscope in vivo. We tested whether hypoxic vasodilation and hyperoxic vasoconstriction in arterioles in striated muscle are being propagated upstream, and whether the endothelium and smooth muscle cell layers are necessary components in the signaling pathway.
Methods: The study was performed in mouse cremaster muscle superfused with Krebs buffer.
