Baseline tear fluid CGRP is elevated in active cluster headache patients as long as they have not taken attack abortive medication.
Abstract
Calcitonin gene-related peptide plays a key role in cluster headache pathophysiology. It is released from the trigeminal nerve, which also innervates the eye. In this study, we tested if tear fluid calcitonin gene-related peptide measurement detects elevated calcitonin gene-related peptide levels in cluster headache patients compared to controls.
