Summary

This trial tests whether giving a fluorescent dye called indocyanine green during endoscopic surgery helps surgeons remove non-functioning pituitary macroadenomas more completely. About 34 adults with these tumors will be randomly assigned to receive the dye or not during surgery. The study compares how often the tumor is fully removed and whether complications are fewer, with follow-up MRI scans and eye exams to check outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Indocyanine green dye given intravenously during endoscopic endonasal transsphenoidal surgery to visualize the tumor in real time.
What this could lead to
If it works, this could make pituitary tumor removal more complete and reduce complications, improving recovery and long-term outcomes for patients.
What could go wrong
This is a small pilot study, so results may not be definitive. The dye carries a risk of allergic reactions, especially in people with iodine allergies.
