A cursory googling led here: > Dopamine is a key neurotransmitter in the signaling cascade controlling ocular refractive development, but the exact role and site of action of dopamine D1 receptors (D1Rs) involved in myopia remains unclear. [.. snip ..] > Therefore, activation of D1Rs, specifically retinal D1Rs, inhibits myopia development in mice. These results also suggest that multiple dopamine D1R mechanisms play roles in emmetropization and myopia development. https://www.jneurosci.org/content/43/48/8231 https://www.jneurosci.org/content/43/48/8231
