Ocular Complications in the Prone Position in the Critical Care Setting: The COVID-19 Pandemic.

Purpose: Ocular complications are common in the critical care setting but are frequently missed due to the focus on life-saving organ support. The SARS-CoV-2 (COVID-19) pandemic has led to a surge in critical care capacity and prone positioning practices which may increase the risk of ocular complications. This article aims to review all ocular complications associated with prone positioning, with a focus on challenges posed by COVID-19.

Pharmacotherapeutic management of atopic keratoconjunctivitis.

Introduction: Atopic keratoconjunctivitis (AKC) is a form of allergic eye disease that can have sight threating implications. Prevalence is underestimated due to scarce published data and treatment is expanding as a result of limitations of current strategies. This article aims to provide an up-to-date overview of AKC and summarize current and upcoming management.

Effect of varying skin surface electrode position on electroretinogram responses recorded using a handheld stimulating and recording system.

Purpose: A handheld device (the RETeval system, LKC Technologies) aims to increase the ease of electroretinogram (ERG) recording by using specially designed skin electrodes, rather than corneal electrodes. We explored effects of electrode position on response parameters recorded using this device.

Methods: Healthy adult twins were recruited from the TwinsUK cohort and underwent recording of light-adapted flicker ERGs (corresponding to international standard stimuli).

Variations in Treatment Delivery for Patients with Neovascular AMD in the UK: Results from an Ophthalmology Trainee Clinical Research Network Study.

Introduction: The aim of this study was to determine treatment delivery patterns for patients with neovascular age-related macular degeneration (nAMD) across the UK through an ophthalmology trainee research network delivered observational study.

Methods: Data were collected via an online tool by potential research collaborators identified by the Ophthalmology Trainee Clinical Trial Network (OCTN). Collaborators were asked to comment on periprocedural practices of treatment of nAMD in their eye unit including treatment location and injectors, clinical assessment and routine observation in patients undergoing intravitreal treatment.

The benefits of a peer-assisted mock PACES.

Background: Peer-assisted learning (PAL) and mock examinations have been credited as effective teaching tools; however, there is a lack of research into their effectiveness in PACES (practical assessment of clinical examination skills). This study demonstrates an effective model and the benefits of PAL after its implementation in a mock PACES at Imperial College London. There is a lack of research into the effectiveness of PAL and mock examinations in PACES METHODS: A mock PACES was designed for fifth-year medical students.

Do twins share the same dress code? Quantifying relative genetic and environmental contributions to subjective perceptions of "the dress" in a classical twin study.

The phenomenon of contrasting color perceptions of "the dress" photograph has gained scientific interest. The mechanism underlying why individuals differ is yet to be fully explained. We use the powerful twin model design to ascertain the relative contribution of genetic and environmental factors on perception variation.

Orbital mass secondary to infantile acute lymphoblastic leukaemia.

An 8-month-old Asian infant girl was referred with a 1-week history of left periorbital swelling on a background of a narrowed left palpebral aperture over the preceding 8 weeks. There was no history of chronic illness, fever or other systemic features. Examination revealed a tender and fluctuant medial canthal swelling with associated periorbital haematoma.
