EYE SYMPTOMS AND THE PARKINSONIAN SYNDROME

Definite etiology in association with clearly defined symptomatology and confirmation by microscopic study must be made and interpreted before the relation of the parkinsonian syndrome to ocular symptoms can be classified clearly. In some cases a clear association is defined, and again it seems extremely difficult to fathom the combination. Encephalitis is so varied in its portrayal of symptoms ; in certain phases it has a predilection for ocular muscles and again it apparently ignores the ocular syndrome.
