If untreated, xerophthalmia can lead to dry eye syndrome, corneal ulceration, and ultimately to blindness as a result of corneal and retinal damage. Xerophthalmia usually implies a destructive dryness of the conjunctival epithelium due to dietary vitamin A deficiency—a rare condition in developed countries, but still causing much damage in ...

The condition is permanent with no known treatment. The new study was based on an analysis of medical records spanning six years from more than 16,800 patients in the Boston area, none of whom ...
If untreated, xerophthalmia can lead to dry eye syndrome, corneal ulceration and ultimately to blindness as a result of cornea and retina damage. Although xerophthalmia is an eye-related issue, prevention (and reversal) are functions of retinoic acid having been synthesized from retinal rather than the 11-cis-retinal to rhodopsin cycle. [22]

[ 10 ] Night blindness and its worsened condition, xerophthalmia , are markers of Vitamin A deficiency; collections of keratin in the conjunctiva , known as Bitot ...
