Abstract
Two 3-year prospective studies from 1982–1984 and 1986–1988 in Tanzania identified 189 children with corneal ulceration, of whom 31 (16 · 4%) were due to vitamin A deficiency. In 1982–1984, vitamin A deficiency was responsible for 23 · 4% of corneal ulcers (25 of 107) compared with 7 · 3% (6 of 82) from 1986–1988 (P = 0 · 006). It is postulated that the decrease in corneal ulceration due to vitamin A deficiency can be attributed to improved measles immunization coverage.Keywords
