Assessing Benefits of NIRAF Detection for Identifying Parathyroid Glands During Total Thyroidectomy

Medical College of Wisconsin·interventional·Posted Oct 14, 2022·Updated Jul 31, 2025

In Brief

A clinical study evaluating NIRAF Detection Technology for Postoperative Hypoparathyroidism and 3 related conditions. Completed, enrolled 80 participants across 1 site.

Detailed Summary

This study describes a single center, randomized, single-blinded clinical trial to assess the clinical benefits of the use of near infrared autofluorescence (NIRAF) detection with an FDA-cleared device 'Parathyroid Eye (PTeye)' for identifying parathyroid glands during total thyroidectomy. It compares risk-benefits and outcomes in patients undergoing total thyroidectomy where NIRAF detection with PTeye for parathyroid identification is either used or not used.

Interventions

NIRAF Detection Technologydevice

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). After 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. Other Name: PTeye Device
