The author describes two cases. One suffered from photophobia, pain over the eyes, and vomiting. Her perceptions were inexact in regard to details and identifying features. During analysis she kept her eyes closed and covered them with her hands, a way of preventing herself from being overwhelmed by scoptophilic and exhibitionistic impulses. The second patient was sensitive to all kinds of sensory impressions which he reduced by smoking. Not only would the smoking subdue these vivid impressions, but it also slowed his thoughts and his aggressive impulses. Per contra, when he gave up smoking there was a hypersensitivity to taste and smell.
