Predictive Factors for Biopsy-Negative Giant Cell Arteritis and Alternative Diagnoses in a Neuro-Ophthalmology Context.

Giant cell arteritis is a challenging diagnosis for patients given the high prevalence of negative temporal artery biopsies (TAB). Despite the lack of histopathological evidence of giant cell arteritis in the TAB, patients can still have TAB-negative giant cell arteritis. The purpose of this paper is to analyse the predictors for TAB-negative giant cell arteritis and the alternative diagnosis of biopsy-negative patients without a giant cell arteritis diagnosis.

Thinking Beyond Giant Cell Arteritis in COVID-19 Times.

Background: The coronavirus disease 2019 has displayed multi-system manifestations since its first presentation. This article highlights an unusual presentation of COVID-19 that was reviewed by our instituition's otolaryngology and ophthalmology team.

Methods: We present 2 cases of COVID-19 which presented with unilateral otalgia and ipsilateral pulsatile headaches involving the temporal area.

Parent satisfaction and acceptability of telehealth consultations in pediatric ophthalmology: initial experience during the COVID-19 pandemic.

Telehealth in pediatric ophthalmology has predominantly been utilized and reported in the setting of clinician-to-clinician opinion or store-and-forward of images, particularly in the diagnosis and management of retinopathy of prematurity (ROP). We present our initial experience of using a telehealth model of care to deliver real-time specialist pediatric ophthalmology services during the COVID-19 pandemic. Over a 5-week period, parents were invited to complete an anonymous survey following a telehealth ophthalmology consultation for their child.

The Usefulness of Anti-acetylcholine Receptor Binding Antibody Testing in Diagnosing Ocular Myasthenia Gravis.

Background: Anti-acetylcholine receptor antibody (AChR-Abs) testing is a safe and simple ancillary method for confirming the diagnosis of myasthenia gravis. Despite the test's high sensitivity (85%-90%) for generalized myasthenia gravis, AChR-Abs testing has been reported to have a low sensitivity 44%-66% for ocular myasthenia gravis (OMG). The aim of the study is to assess the effectiveness of AChR binding Abs testing for diagnosing OMG by evaluating the test's sensitivity, specificity, positive predictive value, and negative predictive value.

Video recording in ophthalmic surgery.

Video recording in ophthalmic surgery has immense potential to drive quality improvement in patient care, ophthalmology training, and research. Not only do surgical videos permit introspective and critical analyses of surgical technique, they also allow for objective assessment, allow for more informative audits, and are an invaluable medium for surgical education. Unfortunately, medical-grade video recording equipment is often costly.

New trends in childhood vision impairment in a developed country.

Background: The Education Vision Assessment Clinic (EVAC) is a unique statewide service that reviews school children 4-18 years of age with low vision in Victoria, Australia, to determine their eligibility for educational support. The purpose of this study was to identify causes of vision impairment in students in Victoria using data from the EVAC.

Methods: Data collected from students who attended the EVAC at the Royal Victorian Eye and Ear Hospital, Melbourne, between the years 2003 and 2012 inclusive, were analyzed retrospectively.
