Glowing goggles could prevent calcium crash after thyroid surgery
NCT ID NCT07617584
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a wearable goggle system that makes parathyroid glands glow can help surgeons find and protect them during thyroid removal. About 280 adults having thyroid surgery will take part. The goal is to reduce the risk of low calcium levels after surgery, a common complication when parathyroid glands are accidentally damaged or removed.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18 years or older. * For Component A: planned thyroidectomy of any extent with an intact specimen available for ex vivo evaluation. * For Component B: planned total or completion thyroidectomy. * Ability to provide written informed consent before surgery. * Willingness to comply with routine postoperative laboratory testing and follow-up when feasible. Exclusion Criteria: * Known pre-existing hypoparathyroidism or prior parathyroid surgery. * Severe chronic kidney disease or end-stage renal disease expected to substantially confound calcium and parathyroid hormone interpretation, as defined by the site investigator. * Pregnancy. * For Component B only: gross nodal disease or a surgical plan requiring extensive nodal packet dissection in the current study phase. * Any condition that, in the judgment of the investigator, would make participation unsafe or compromise protocol adherence.
