We recorded steady-state (4.19 and 8.41 Hz) VEPs in 17 Parkinson's Disease (PD) patients and 18 control observers using on-off temporal modulation of a 2.3 c/deg sinusoidal grating. With 4.19 Hz, 20 out of 33 PD patient eyes had abnormal VEPs. Howeve

Human and rat retina dopamine (DA) and its metabolites dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) were measured after various delays in enucleation and freezing of the eyes. Human eyes were enucleated 45 min to 4 h after death, ke

The visual function of three infants with sporadic aniridia associated with Wilms' tumor and a deletion of the short arm of chromosome 11 was evaluated with electrophysiological tests. The patients presented nystagmus and photophobia. The electroreti

• We performed threshold static perimetry on 19 patients who had ingested canthaxanthin; 11 had maculopathy and eight did not. Patients with no history of canthaxanthin ingestion served as controls. All patients had visual acuity of 6/9 or better.

• Canthaxanthin intake is associated with golden yellow crystalline deposits in the retina around the macula and low static luminance threshold. Our study assesses the anatomic and functional reversibility of canthaxanthin retinopathy. The number o

The influences of N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) on dopamine content in the retina and the, striatum of monkeys, as well as retinal responses to flash stimulation were studied. Dopamine depletion was observed in the striatum, whi

Anatomical studies have demonstrated that the output of the striopallidal system is distributed to two areas of the thalamus: the ventrolateral-vertroanterior and the centromedian nuclei. The two areas are involved in different ways in the control of
