HC Deb 02 February 1982 vol 17 c112W
Mr. Carter-Jones

asked the Secretary of State for Wales how many children under five years of age were registered as blind or partially sighted as a result of retrolental fibroplasia for each year from 1965 to 1981.

Mr. Wyn Roberts

Detailed analyses of the type necessary to answer the question accurately for Wales separately are not carried out, but, on the overall Great Britain pattern, less than one case per annum of this type would be expected in Wales.
