Abstract
During the period 1962-1986, 54 patients received the diagnosis hysterical visual impairment, i.e. 1 out of every 631 patients admitted to our department. Isolated visual acuity impairment was the most common symptom, followed by combined visual acuity impairment and visual field constriction, whereas isolated visual field constriction occurred most infrequently. The mean age of the patients in the first group was significantly lower than that of the patients in the latter group. A questionnaire sent to all patients in 1987 was answered by 41 patients. Twenty-one of these (51%) felt that their visual function now was good, whereas 20 (49%) claimed that their visual function was still poor. Nine patients (22%) were disabled because of their visual problems. Twenty-nine of the patients who answered the questionnaire were re-examined. Sixteen of these (55%) still showed visual impairment at the follow-up, while 13 (45%) showed complete disappearance of visual complaints. The younger patients appeared to have a better prognosis than the older ones.
