Abstract

We carried out the Schirmer test to measure objectively the amount of lacrimation among 51 clinically diagnosed parkinsonian patients (33 men and 18 women aged 50 to 79 years, mean 64) and 75 age-matched controls (42 men and 33 women aged 50 to 76, mean 62). Whatman No. 2 paper, prepared in precut strips 5mm by 35mm, was placed in the cul-de-sac for five minutes, after which the wetted length of the strip was studied. It was noted that the lacrimation amount decreased in patients with Parkinson's disease compared with controls: the average amount of lacrimation was 3.4 ± 2.3mm in the former group and 8.1 ± 6.5mm in the latter group (p < 0.01). We believe that the decrease in the amount of lacrimation is associated with emotional disturbance and autonomic dysfunction, and presume that the lacrimation may be under the control of the basal ganglia which has a connection with the superior salivatory nucleus downward and the limbic system upward.
