Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Biodistribution & persistence
Rabbit eye: metabolite distributed to all ocular tissues within 30 min; highest in cornea and iris
“3-quinuclidinol distributed to all ocular tissues analyzed within 30 minutes of treatment. The rank order of the exposure was: cornea > iris > choroid > aqueous humor > sclera > retina > lens ≈ vitreous humor.”
Systemic exposure quantified via metabolite 3-quinuclidinol as surrogate
“Assays for systemic and ocular exposure to the metabolite 3-quinuclidinol were developed, and 3-quinuclidinol exposure was used as a surrogate to determine ocular distribution and quantify systemic exposure.”
