Poor nutrition may be complicated by dry eye.


Diagnostic considerations:

(1) history of a nutritional deficiency

(2) correction of dry eye after correction of the nutritional deficiency

(3) no other alternative diagnosis that can explain the findings better


Nutritional factors that may contribute to dry eye:

(1) hypovitaminosis A

(2) hypovitaminosis B2

(3) hypovitaminosis B12

(4) dehydration


Patients in whom "hyponutritional" dry eye should be considered include:
