In vivo, micro‐morphological vascular changes induced by topical brimonidine studied by Dynamic optical coherence tomography

The vascular constriction induced by topical brimonidine gel 0.33% was visualized in vivo by Dynamic OCT and confirmed by quantitative measurements and analyses. This study shows that Dynamic OCT can detect characteristic morphological changes in the vessels and may potentially aid the monitoring of treatment effects on skin vessels following topical or laser treatment.
