PrÉcis: Using a controlled experimental design with corneal phantoms, this study provides evidence of the lack of validity of a static air quality indicator, previously used to characterize aerosolization during dynamic noncontact tonometry.
Purpose: To evaluate the accuracy of aerosol concentrations reported by an air quality indicator (AQI) following an air puff from a noncontact tonometer using non-aerosolizing corneal phantoms.
Methods: Three rubber corneal phantoms of different stiffnesses were used to represent varying intraocular pressure (IOP) values.
Introduction: The safety and efficacy of colonic band ligation and auto-amputation (1) as adjunct to endoscopic mucosal resection of large laterally spreading tumors and (2) for polyps not amenable to routine polypectomy due to polyp burden or difficult location remain unknown.
Methods: An institutional review board-approved retrospective single-institution study was undertaken of patients undergoing colonic band ligation and auto-amputation from 2014 to date. Patients with indications of 'endoscopic mucosal resection for laterally spreading tumors' and 'polyp not amenable to snare polypectomy' were included in the study.
