Diseases & Conditions

Xerophthalmia is an eye disease caused by a deficiency of vitamin A, leading to severe dryness in the eyes. If left untreated, the condition can worsen, resulting in night blindness, making it difficult to see in low-light conditions. In more advanced stages, it can cause the formation of Bitot’s spots—foamy patches on the whites of the eyes. Over time, the cornea may become damaged, leading to ulceration, scarring, and, in severe cases, irreversible blindness.
