Hakan Kaymak studies the time cinetics of the release of dopamine and its metabolites from the retina. Drugs that suppress myopia are particularly interesting.

He has found that dopamine agonists (pramipexole) can cause a long lasting decline in retinal dopamine content and a short-term decline in its release.
He and Gabi Hagel found also that atropine, which blocks myopia development with occluders, causes a long-lasting (> 6 hours) increase in retinal dopamine content and release.
