General: Deficient serum levels of vitamin A; principal cause of infantile blindness in the world; due to insufficient intake of vitamin A or interference with its absorption from the intestinal tract; transport or storage in the liver; obstruction of biliary tract or pancreatic ducts.
Ocular: Bitot spot; xerosis; keratomalacia; keratitis; corneal perforation and ulcer; corneal opacity; hyperkeratosis; retinal degeneration; scotoma.
Clinical: Inadequate dietary intake or interference with absorptive storage or transport capacities, as occurs in liver disease, sprue, regional enteritis, and chronic gastroenteritis; respiratory infection; diarrhea; reduced childhood mortality.
