HC Deb 02 February 1982 vol 17 c73W
Mr. Carter-Jones

asked the Secretary of State for Northern Ireland 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. John Patten

The information is not recorded centrally and could be collected only at disproportionate cost.
