Summary: The present study compares lacrimal secretion in control subjects and patients with Parkinson's disease with use of Schirmer's test. Tear secretion was decreased in Parkinson's disease. The reduction was more marked in stages III-IV than in stages I-II. The results are discussed in relationship with autonomic dysfunction in Parkinson's disease.
