Comparison of clinical characteristics and outcomes of critically ill adults with SARS-CoV-2 infection during Delta and Omicron variant predominance periods: a single-hospital retrospective cohort study.

Introduction: Initial reports suggest the B.1.1.

Video Education on Hereditary Breast and Ovarian Cancer (HBOC) for Physicians: an Interventional Study.

The National Comprehensive Cancer Network (NCCN) guidelines are the gold standard in hereditary cancer risk assessment, screening, and treatment. A minority of physicians follow NCCN guidelines for BRCA1 or BRCA2 mutations. This study assesses the impact of an interventional educational program on HBOC in terms of knowledge.

Learning styles and the prospective ophthalmologist.

Purpose: Understanding the learning styles of individual trainees may enable trainers to tailor an educational program and optimise learning. Surgical trainees have previously been shown to demonstrate a tendency towards particular learning styles. We seek to clarify the relationship between learning style and learned surgical performance using a simulator, prior to surgical training.

Safety of nondominant-hand ophthalmic surgery.

Purpose: To establish the safety of nondominant-hand simulated intraocular surgery.

Setting: Horizon Suite Simulation Centre, South Devon Foundation NHS Trust, Devon, United Kingdom.

Design: Cohort study.

Can virtual reality simulation help to determine the importance of stereopsis in intraocular surgery?

Aim: To establish the effect of acute loss of stereopsis on simulated intraocular surgical performance.

Methods: This study was performed using the EYESi ophthalmic surgical simulator. Thirty junior doctors with no previous ophthalmic surgical experience were enrolled and distance visual acuity (Snellen), near visual acuity and stereoacuity (Frisby) were recorded.

Effect of distraction on simulated anterior segment surgical performance.

Purpose: To determine the effect of distraction on anterior segment surgical performance using a virtual reality simulator in expert and novice surgeons.

Setting: Horizon Suite Simulation Centre, South Devon Foundation NHS Trust, Devon, England.

Design: Cohort study.

Glaucoma surgery.

Glaucoma is a potentially blinding condition that cannot be easily defined. There are various types of glaucoma which may vary in symptoms from none at all to sudden pain and redness. There is a characteristic optic neuropathy, or damage to the optic nerve, which results in progressive loss of visual field.

Assessment of fatigue in intraocular surgery: analysis using a virtual reality simulator.

Aim: To determine the effect of fatigue on intraocular surgical performance using a virtual reality simulator.

Methods: Seven experienced ophthalmic surgeons were recruited. The first set of data collection was immediately before a live theatre session.

Strabismus: background and surgical techniques.

Through the process of evolution, the position of the eyes within the head has moved from lateral to frontal. Although reducing the panoramic view afforded by the lateral positioning, this new arrangement allowed stereopsis (depth perception) (Hubel and Wiesel 1965).

Genotype analysis of polymorphisms in autoimmune susceptibility genes, CTLA-4 and PTPN22, in an acute anterior uveitis cohort.

Purpose: Acute anterior uveitis (AAU) is the most common form of uveitis and is thought to be autoimmune in nature. Recent studies have described genes that act as master controllers of autoimmunity. Protein tyrosine phosphatase type 22 (PTPN22) and Cytotoxic T lymphocyte antigen-4 (CTLA-4) are two of these genes, and single nucleotide polymorphisms (SNPs) in the genes encoding these molecules have been associated with several autoimmune diseases.

Local anaesthetic cataract surgery: factors influencing perception of pain, anxiety and overall satisfaction.

To assess factors influencing perception of pain, anxiety and overall satisfaction during local anaesthetic cataract surgery an audit was carried out at the West of England Eye Unit. Patients receiving sub-Tenons after previous peribulbar anaesthesia had significantly higher pain scores. Patient satisfaction was significantly higher when a handholder was present in theatre.
