- Inhibiting the neuronal isoform of nitric oxide synthase has similar effects on the compensatory choroidal and axial responses to myopic defocus in chicks as does the non-specific inhibitor L-NAMEDebora L Nickla
The New England College of Optometry, Bioscience Department, 424 Beacon St, Boston, MA 02115, USA
Exp Eye Res 88:1092-9. 2009..We conclude that the choroidal compensatory response is influenced by nNOS, possibly from the intrinsic choroidal neurons, or the parasympathetic innervation from the ciliary and/or pterygopalatine ganglia...

The New England College of Optometry, Department of Biosciences, 424 Beacon Street, Boston, MA 02115, USA
Exp Eye Res 84:951-9. 2007..The choroidal response was not significant. These results support the hypothesis that these brief choroidal responses may play a role in ocular growth inhibition...
