Dopaminergic behaviour in chicken retina and the effect of form deprivation

ABSTRACT Purpose: Dopamine (DA)is cinsidered to be a neurotransmitter involved in light‐adaptive responses in the retina and has been implicated in the control of the eye growth include by form deprivation vitreal DOPAC was shown to be a good indicator of retinal dopaminergic activity. Methods/Results: Dopaminergic activity was highest during the light, with vitreal DOPAC levels rising within in 3 hof light exposure. Form deperivation attenuated dopaminergic activity, as the rise in vitreal DOPAC levels on light exposure was rediced in form‐depeived eyes, compared with control eyes. Conclusion: The lack sustained activation of DA release may explain the role of DA in the control of eye‐growth.
