Dacryocystorhinostomy videos on YouTube as a source of patient education.

Background: To determine the quality and reliability of DCR YouTube videos as patient education resources and identify any associated factors predictive of video quality.

Methods: A YouTube search was conducted using the terms "Dacryocystorhinostomy, DCR, surgery" on 12th of January 2022, with the first 50 relevant videos selected for inclusion. For each video, the following was collected: video hyperlink, title, total views, months since the video was posted, video length, total likes/dislikes, authorship (i.

Central retinal artery occlusion: a stroke of the eye.

Central retinal artery occlusion (CRAO), like a stroke in the brain, is a critical eye condition that requiring urgent medical attention. Patients with CRAO present with acute loss of vision and the visual prognosis is poor with low chance of spontaneous visual recovery. Moreover, the risk of developing ischaemic heart disease and cerebral stroke is increased due to the presence of underlying atherosclerotic risk factors.

Nationwide Trends in Vitreoretinal Procedures within Australia.

Purpose: To investigate Australian age stratified nationwide trends in vitreoretinal procedures.

Methods: Nationwide retrospective analysis of vitreoretinal procedures in Australia over 2001-2019 using Australian National Hospital Morbidity Database for public and private hospitals. Age and gender-specific trends in selected procedures including pars plana vitrectomy for retinal detachment (PPV for RD), scleral buckle, intravitreal injections, and PPV unrelated to RD were analysed using negative binomial regression.

Overcoming the impact of physiologic tremors in ophthalmology.

Purpose: Ophthalmic surgery involves the manipulation of micron-level sized structures such as the internal limiting membrane where tactile sensation is practically absent. All humans have physiologic tremors that are of low amplitude and not discernible to the naked eye; they do not adversely affect the majority of the population's daily functioning. However, during microsurgery, such tremors can be problematic.

The potential impact of 5G telecommunication technology on ophthalmology.

Advances in information and communication technology (ICT) are having an increasing impact on the practice of ophthalmology. Successive generations of 4G networks have provided continued improvements in bandwidth and download speeds. Fibre-optic networks were promised as the next step in the development of a faster and more reliable network.

Polyp Detection Rate as a Surrogate for Adenoma and Sessile Serrated Adenoma/Polyp Detection Rates.

Introduction: Quality measures for colonoscopy such as adenoma detection rate (ADR) have been proposed to be surveilled for ensuring minimum standards. However, its direct measurement is time consuming and often neglected. Extrapolating ADR and other quality measures from polyp detection rate (PDR) can be a pragmatic alternative.

Different factors are associated with conventional adenoma and serrated colorectal neoplasia.

Current data shows there are differences in factors associated with colorectal neoplasia based on geographical location and cultural settings. There are no studies focusing on the association between environmental factors and colorectal polyps in Australia. The aim of this study was to prospectively evaluate the association of various factors with different colorectal neoplasia histology.

Computer-aided diagnosis for characterization of colorectal lesions: comprehensive software that includes differentiation of serrated lesions.

Background And Aims: Endoscopy guidelines recommend adhering to policies such as resect and discard only if the optical biopsy is accurate. However, accuracy in predicting histology can vary greatly. Computer-aided diagnosis (CAD) for characterization of colorectal lesions may help with this issue.

Effect of time of day and specialty on polyp detection rates in Australia.

Background And Aim: Adenoma detection rate (ADR) is an important quality metric in colonoscopy. However, there is conflicting evidence around factors that influence ADR. This study aims to investigate the effect of time of day and endoscopist background on ADR and sessile serrated adenoma/polyp detection rate (SSA/P-DR) for screening colonoscopies.
