{"eventGroups":[{"deathsNumAffected":0,"deathsNumAtRisk":80,"description":"Parathyroid gland identification will be performed with PTeye using NIRAF detection technology as an adjunctive tool in patients who undergo parathyroidectomy (PTx).\n\nNIRAF Detection Technology: Near Infrared Autofluorescence (NIRAF) detection technology or 'PTeye' consists of a disposable fiber-optic probe that emits non-ionizing radiation from a NIR 785 nm laser source, and also transmits the resulting tissue NIRAF to a photo detector. The 785 nm laser source emits a maximum power of 20 mW. The device is FDA cleared for clinical use in general surgeries and dermatological use (Class 2 device).\n\nAfter surgeon identifies a potential parathyroid gland in the surgical field, the surgeon places the fiber-optic probe of PTeye on suspect tissue and presses the device foot-pedal to activate tissue NIRAF measurement. Auditory beep at high frequency with a Detection Ratio \\> 1.2 is interpreted by device as the suspect tissue being positive for parathyroid.","id":"EG000","otherNumAffected":0,"otherNumAtRisk":80,"seriousNumAffected":0,"seriousNumAtRisk":80,"title":"NIRAF Detection Technology +"},{"deathsNumAffected":0,"deathsNumAtRisk":80,"description":"Parathyroid gland identification will be performed with the naked eye of the surgeon without using PTeye - NIRAF detection technology in patients who undergo parathyroidectomy (PTx).","id":"EG001","otherNumAffected":0,"otherNumAtRisk":80,"seriousNumAffected":0,"seriousNumAtRisk":80,"title":"NIRAF Detection Technology -"}],"frequencyThreshold":"0","timeFrame":"Adverse event data was collected for 2 years, 5 months."}
