Purpose: To describe a graded eyelid crease approach to access the superior orbital apex, and to quantify the working space enabled with the sequential release of structures along the superior orbital rim.

Methods: Cadaveric dissection study of 7 cadaver heads (14 orbits). This technique involved a subperiosteal approach to the superior orbital apex.

Given their frontline role in Australia and Aotearoa New Zealand (ANZ) healthcare, trainee medical officers (TMOs) will play a crucial role in the development and use of artificial intelligence (AI) for clinical care, ongoing medical education and research. As 'digital natives', particularly those with technical expertise in AI, TMOs should also be leaders in informing the safe uptake and governance of AI within ANZ healthcare as they have a practical understanding of its associated risks and benefits. However, this is only possible if a culture of broad collaboration is instilled while the use of AI in ANZ is still in its initial phase.

Fungal rhinosinusitis (FRS) includes non-invasive and invasive subtypes with the latter having significant morbidity and mortality. This systematic review aims to identify the imaging features most correlated with invasive fungal rhinosinusitis (IFRS) and present a checklist of these features to aid diagnosis. PubMed, Embase, CENTRAL, and Science Direct were searched from inception to May 2023, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines.

Purpose: To develop and evaluate a transorbital endoscopic approach to the foramen rotundum to excise the maxillary nerve and infraorbital nerve branch.

Methods: Cadaveric dissection study of 10 cadaver heads (20 orbits). This technique is predicated upon 1) an inferior orbital fissure release to facilitate access to the orbital apex and 2) the removal of the posterior maxillary wall to enter the pterygopalatine fossa (PPF).

Introduction: Optic neuritis may occur in a variety of conditions, including as a manifestation of multiple sclerosis. Despite significant research into the efficacy of corticosteroids as a first-line treatment, the optimal route of administration has not been well defined. This review aims to explore the efficacy, adverse effects and economic implications of using oral versus intravenous methylprednisolone to treat acute optic neuritis.

Background: Endophthalmitis following intravitreal injection is a potentially devastating complication of anti-VEGF injections. Post-injection endophthalmitis due to Enterococcus faecalis is rare, and no previous case of Morganella morganii endophthalmitis after intravitreal injection has been reported.

Case Presentation: We present the first reported case of Morganella morganii and Enterococcus faecalis endophthalmitis after intravitreal injection in an immunocompetent patient in the absence of recent ocular surgery.

Purpose: To determine whether Twitter improves dissemination of ophthalmology scientific publications METHODS: Data were collected on articles published on PubMed between the years 2016 and 2021 (inclusive) and identified with the word "ophthalmology". Twitter performance metrics, including the number of tweets, number of likes, and number of retweets were collected from Twitter using the publicly available scientific API. Machine learning and descriptive statistics were used to outline Twitter performance metrics.

Purpose: To outline the environmental and financial costs associated with single-use topical antiseptic (5% povidone-iodine [PVI] solution) in the ophthalmology theatre setting and explore potential methods of repurposing topical antiseptics.

Setting: Large tertiary referral center (Flinders Medical Centre, Adelaide, Australia).

Design: Single-center prospective observational study.

Purpose: Advances in artificial intelligence (AI)-based named entity extraction (NER) have improved the ability to extract diagnostic entities from unstructured, narrative, free-text data in electronic health records. However, there is a lack of ready-to-use tools and workflows to encourage the use among clinicians who often lack experience and training in AI. We sought to demonstrate a case study for developing an automated registry of ophthalmic diseases accompanied by a ready-to-use low-code tool for clinicians.

Objectives: Blood tests for endocrinological derangements are frequently requested in general medical inpatients, in particular those in the older age group. Interrogation of these tests may present opportunities for healthcare savings.

Methods: This multicentre retrospective study over a 2.

Article Synopsis
  • The study explores how machine learning can be used with optical coherence tomography angiography (OCTA) to predict cardiovascular conditions and risk factors in individuals based on changes in the retinal microvasculature.
  • Researchers conducted a cross-sectional study with 247 participants, collecting demographic and health data while using varying scan sizes (3 × 3 mm, 6 × 6 mm, 8 × 8 mm) to analyze the data with two machine learning models (Convolutional Neural Network and MobileNetV2).
  • Results showed that both models effectively identified hyperlipidaemia in the 3 × 3 mm scans, achieving AUC scores of 0.74 and 0.81, while their

Background: The accurate encoding of operation notes is essential for activity-based funding and workforce planning. The aim of this project was to evaluate the procedural coding accuracy of vitrectomy and to develop machine learning, natural language processing (NLP) models that may assist with this task.

Methods: This retrospective cohort study involved vitrectomy operation notes between a 21-month period at the Royal Adelaide Hospital.

Fluorescein angiography in retinopathy of prematurity is increasingly utilized over the past decade. The development of ultra-wide-field imaging combined with fluorescein angiography has allowed improved visualization of the peripheral retinal vasculature. Patient cooperation in the pediatric population is particularly challenging, but hand-held digital retinal photography has shown promise and can visualize the infant retina without the need for anesthesia and intravenous access.
