Both writers' and telegraphists' cramp are excrescences upon an underlying psychoneurosis, though associated symptoms are often overlooked.Miners' nystagmus supposed to be a physiological disorder that produces "neurasthenia"; ocular symptoms mostly psychoneurotic; the oscillation not a disability of itself.Night-blindness as a hysterical symptom. History of night-blindness in armies; its epidemic prevalence in Continental armies in the Great War and its comparative rarity in ours. Its absence in war pensioners and possible replacement by fear of the dark. Night-blindness in nystagmus probably a conversion of this fear.Accounts of nystagmus in crane-workers and train dispatchers.

Possibly the ocular disability behaves as a hysteria in guarding against further symptoms.Appearance of an occupational disorder among deep-sea divers, and the psychological investigation of individual cases described.
