Epidemiology

 

Incidence

Mantyjarvi 1.4 cases/1000 children (7-18 years)/year.

Prevalence

Eames (1947) 9% of 193 unselected children exhibited tubular fields. A third of these children had hysterical personalities.

Personal experience (Dr Barnard) is that VCR is not uncommon in a busy paediatric practice and may be more prevalent amongst large orthodox religious families.

Age & sex

Youngest in literature (Wolpe, 1953) is a 2-year old with amaurosis.

Modal peaks (all literature) occur at 10-11 and 13-14 year-old age groups.

4 times more common in females why ?
