ICD-11 code : 5B55;
Preferred Label : Vitamin A deficiency;
ICD-11 definition : Vitamin A deficiency (VAD) is defined as a state in which tissue concentrations of
vitamin A are low enough to have adverse health consequences even if there is no evidence
of clinical xerophthalmia. The term xerophthalmia encompasses the clinical spectrum
of ocular manifestations of vitamin A deficiency, from milder stages of night blindness
and Bitot's spots, to potentially blinding stages of corneal xerosis, ulceration and
necrosis (keratomalacia). In addition to the specific signs and symptoms of xerophthalmia
and the risk of irreversible blindness, nonspecific symptoms include increased morbidity
and mortality, poor reproductive health, increased risk of anaemia, and contributions
to slowed growth and development.;
