Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Vitamin A plays a critical role in maintaining eye health, particularly in the function and integrity of the conjunctival and corneal epithelia. There is robust scientific evidence supporting its use in preventing and treating certain eye conditions, especially those associated with vitamin A deficiency. Vitamin A deficiency can lead to xerophthalmia, which encompasses a spectrum of ocular manifestations such as conjunctival dryness, corneal ulcers, and increased susceptibility to eye infections due to impaired immune response and epithelial integrity.

Clinical studies and public health programs have demonstrated that vitamin A supplementation significantly reduces the incidence and severity of eye infections and other ocular complications in populations at risk of deficiency, such as young children in developing countries. The World Health Organization (WHO) recommends vitamin A supplementation for children with measles and in regions where deficiency is prevalent, as it can decrease morbidity and mortality from infectious diseases, including those affecting the eyes.

Additionally, topical vitamin A preparations (such as vitamin A ointment) have been found effective in promoting healing of corneal ulcers and treating certain cases of viral or bacterial conjunctivitis, especially when epithelial damage is present. However, vitamin A supplementation is not generally used as a primary treatment for eye infections in individuals with adequate vitamin A status.

In summary, there is strong scientific validation for the use of vitamin A in preventing and supporting the treatment of eye infections, particularly in deficiency states and for epithelial repair, though it is not a stand-alone antimicrobial therapy.
