Abstract

Visual conversion reaction is characterized by fluctuating visual acuity and tubular fields in the absence of any organic lesion. It is thought that the environmental and psychological factors contribute to the onset of symptom. Twenty-two cases of visual conversion reactions were evaluated clinically and the results were as follows. 1. Visual conversion reaction is more frequent in females and children and low vision is almost always affected bilaterally. 2. Sixteen cases(72.7%) showed tubular and constricted fields inspite of normal CT and electrophysiologic responses. 3. Of the cases, 86.4%(19/22) had improved their reduced visual acuity to over 0.8 after treatment with suggestion, placebo, plano lenses and some kind of psychotheraphy.
