Development of an Eco-Friendly Smartphone-Assisted Nystagmus Recording System for Recording Vertigo Attacks Anytime, Anywhere: Pilot App Development Study

Development of an Eco-Friendly Smartphone-Assisted Nystagmus Recording System for Recording Vertigo Attacks Anytime, Anywhere: Pilot App Development Study

Vertigo and dizziness are symptoms of various disorders, including peripheral vestibular, central, cardiovascular, and psychogenic disorders. The 1-year prevalence and incidence of vertigo in adults are 4.9%, and 1.4%, respectively [1]. These conditions, which lead to episodic vertigo attacks, reduce the patients’ quality of life by causing nausea and vomiting, accompanied by headaches or an increased risk of falls [2].

Exploring Generative Pre-Trained Transformer-4-Vision for Nystagmus Classification: Development and Validation of a Pupil-Tracking Process

Exploring Generative Pre-Trained Transformer-4-Vision for Nystagmus Classification: Development and Validation of a Pupil-Tracking Process

Based on these data, 190 trace images were created for each video from patients whose main complaint was dizziness. Videos were created using the same algorithm used to generate trace images of the same individual, with no more than two nystagmus events. After applying the exclusion criteria, trace data were successfully generated for 139 patients.

Monitoring Nystagmus in a Patient With Vertigo Using a Commercial Mini-Infrared Camera and 3D Printer: Cost-Effectiveness Evaluation and Case Report

Monitoring Nystagmus in a Patient With Vertigo Using a Commercial Mini-Infrared Camera and 3D Printer: Cost-Effectiveness Evaluation and Case Report

Commercially available infrared cameras with Wi-Fi and 3 D-printed goggles can be used for web-based medical care by dizziness specialists and physicians in emergency medicine. Despite its promising utility, this study has several limitations. First, the findings are based on a single case, which limits the generalizability of the results. Second, the low resolution of the mini-infrared camera made it difficult to analyze the torsional components of nystagmus due to unclear iris patterns.

Smartphone-Assisted Medical Care for Vestibular Dysfunction as a Telehealth Strategy for Digital Therapy Beyond COVID-19: Scoping Review

Smartphone-Assisted Medical Care for Vestibular Dysfunction as a Telehealth Strategy for Digital Therapy Beyond COVID-19: Scoping Review

Dizziness and vertigo are common symptoms experienced by people of all ages, with lifetime prevalence estimates of 17%-30% for dizziness and 3%-10% for vertigo [1]. Dizziness and vertigo can be caused by various factors, including peripheral vestibular disorders, central disorders, circulatory dysfunction, headache-related vertigo, and psychogenic vertigo, which transcend the framework of medical departments.
