Figure 3. Detection of brimonidine at different time points. (A) Detection of brimonidine at 15 min and 60 min after topical dose.
(n = 3 eyes per time point). (B) Spectra from regions of interest indicated in (A) showing brimonidine signal in the back region of the
eye. Arrows indicate the monoisotopic peak of brimonidine.

signals corresponding to endogenous molecules specific to
the lens and the ciliary body are shown for visualization purposes. It can be seen that the brimonidine signal is concentrated in the front of the eye at 15 min postdose. Coregistration
of IMS with histology reveals that brimonidine was localized
to the cornea, anterior chamber, and iris and may have reached
the posterior segment of the eye.

Transit through Eye at Different Time Points
Having established localization, we next sought to track the
transit of brimonidine by using rabbit eyes at both 15 min and
60 min after the topical dose. At these two early time points,
most of the brimonidine is still in the anterior portion of the

eye (Fig. 3A). However, notable differences in distribution
can be observed. For example, more brimonidine is localized
in the cornea at 15 min compared with 60 min, indicating
drug penetration into the eye and clearance over time. In
addition, brimonidine levels were observed to increase in the
iris from 15 to 60 min (Fig. 4). Imaging data across the multiple animal eyes reproducibly demonstrated that brimonidine was localized in the cornea, aqueous chamber, and iris.
While at these early time points brimonidine is not distributed to a large degree in the back of the eye, some brimonidine was detected in the posterior portion of the eye (Fig.
3B). Brimonidine signal was not detected in the nondosed
contralateral eye (not shown). Furthermore, no metabolites of
brimonidine were detected at either time point examined.
