A survey of clinicians on the use of artificial intelligence in ophthalmology, dermatology, radiology and radiation oncology.

Artificial intelligence technology has advanced rapidly in recent years and has the potential to improve healthcare outcomes. However, technology uptake will be largely driven by clinicians, and there is a paucity of data regarding the attitude that clinicians have to this new technology. In June-August 2019 we conducted an online survey of fellows and trainees of three specialty colleges (ophthalmology, radiology/radiation oncology, dermatology) in Australia and New Zealand on artificial intelligence. There were 632 complete responses (n = 305, 230, and 97, respectively), equating to a response rate of 20.4%, 5.1%, and 13.2% for the above colleges, respectively. The majority (n = 449, 71.0%) believed artificial intelligence would improve their field of medicine, and that medical workforce needs would be impacted by the technology within the next decade (n = 542, 85.8%). Improved disease screening and streamlining of monotonous tasks were identified as key benefits of artificial intelligence. The divestment of healthcare to technology companies and medical liability implications were the greatest concerns. Education was identified as a priority to prepare clinicians for the implementation of artificial intelligence in healthcare. This survey highlights parallels between the perceptions of different clinician groups in Australia and New Zealand about artificial intelligence in medicine. Artificial intelligence was recognized as valuable technology that will have wide-ranging impacts on healthcare.

Effect of virtual reality simulation training on real-life cataract surgery complications: systematic literature review.

Virtual reality simulation (VRS) has become progressively popular as a training tool in ophthalmology. However, debate continues as to whether VRS has resulted in better outcomes for patients after cataract surgery. Accordingly, a qualitative systematic literature review was conducted to identify whether VRS training results in a reduced complication rate after real-life cataract surgery. Included studies measured the effect of VRS on real-life patient outcomes after cataract surgery. Databases searched included MEDLINE (Ovid), The Cochrane Library, Web of Science, PubMed, and CINAHL. A total of 1917 studies were identified, of which 10 studies were included, spanning from 2011 to 2020. The studies comprised 471 ophthalmological residents, with their complication rates assessed after 30 462 cataract surgery procedures. This systematic literature review indicates that VRS seems to be most helpful in reducing the rate of posterior capsular rupture or errant curvilinear capsulorrhexis and had limited evidence in reducing the rate of other complications.

Jaundice and Haematemesis: An Unusual Presentation of Metastatic Malignant Melanoma.

An 87-year-old male presented with jaundice and haematemesis on a background of recent lethargy and a history of excessive alcohol use. The results of a computed tomography (CT) scan indicated either a cirrhotic liver with regenerative nodules or diffuse malignancy. A gastroscopy revealed an ulcerating gastric tumour. The gastric biopsy confirmed the neoplasm as metastatic malignant melanoma, and the patient passed away on the day of diagnosis from acute hepatic failure. This case is unusual as there was an atypical cause of jaundice and haematemesis, and the diagnosis of melanoma was not established until the day of the patient's death.

Minimally invasive glaucoma surgery: Comparison of iStent with iStent inject in primary open angle glaucoma.

IMPORTANCE: Minimally invasive glaucoma surgery has gained significant traction in recent years. This study evaluates the first- and second-generation trabecular micro-bypass stents "iStent" and "iStent inject". BACKGROUND: To evaluate and compare the effect of a single iStent and double iStent inject in primary open angle glaucoma. DESIGN: Prospective comparative case series. PARTICIPANTS: Primary open angle glaucoma patients undergoing trabecular micro-bypass stent insertion combined with cataract surgery. METHODS: Baseline demographic information, preoperative, intraoperative and postoperative outcomes including intraocular pressure (IOP), visual acuity, reliance on glaucoma medication and complications were collected and analysed. MAIN OUTCOME MEASURES: Primary, secondary and tertiary outcome measures were consecutively defined as an IOP of ≤18 mmHg with zero medications, an IOP of ≤18 mmHg with reduced medications or a 20% reduction in IOP with or without medication. RESULTS: The study comprised 145 eyes in the iStent and 100 eyes in the iStent inject group. At 12 months, 56.0% of the iStent and 51.3% of the iStent inject eyes had achieved primary success and 63.1% and 57.7% secondary success. The mean postoperative IOP was 16.6 mmHg in iStent and 16.9 mmHg in iStent inject. Survival analysis demonstrated a greater incidence of failure in the iStent inject beyond 5 months. CONCLUSIONS AND RELEVANCE: Both trabecular micro-bypass stents in this study were effective in reducing IOP and the burden of medication when combined with cataract surgery. There was no statistically significant difference between the two groups across our outcome measures although the iStent inject required earlier recommencement of medications for optimal IOP control.
