Bitot's spots are small, foamy, white patches that appear on the conjunctiva of the eye. They are often a sign of vitamin A deficiency, which can lead to serious eye problems if not addressed. These spots are named after French physician Pierre Bitot, who first described them in the 19th century. Vitamin A is crucial for maintaining healthy vision, immune function, and skin health. When the body lacks this essential nutrient, it can result in various symptoms, including night blindness and dry eyes. Bitot's spots are more common in developing countries where malnutrition is prevalent. Understanding these spots can help in early detection and prevention of more severe eye conditions.

Key Takeaways:

  • Bitot's spots are foamy, white patches on the eye linked to vitamin A deficiency. They can lead to blindness if untreated, but can be reversed with proper treatment and nutrition.
  • Recognizing symptoms and getting regular eye check-ups are crucial for early intervention. Vitamin A supplements, dietary changes, and public health programs can help prevent and treat Bitot's spots.
