Dopamine and myopia.

Dopamine may play a role in form-deprivation myopia in chickens. Anomalies of the dopaminergic system are believed to be responsible for manifestations of symptoms in Tourette Syndrome (TS), a neuropsychiatric disorder. Visual anomalies have been identified in TS. In this paper, refractive error in people suffering from TS is compared with available population studies. Refractive errors in TS are found to be similar to those in the normal population.
