Bitot's spots
Bitot's spots
Bitot's spots (/biːˈtoʊ/; French: [bito]) are foamy, white patches that appear on the conjunctiva, the clear tissue covering the white part of the eye and the inside of the eyelids. They are a sign of vitamin A deficiency, which can lead to serious eye problems and even blindness if not treated.
Etymology
The term "Bitot's spots" is named after the French physician Pierre Bitot, who first described the condition in 1863.
Symptoms
Bitot's spots are typically asymptomatic, meaning they do not cause any discomfort or changes in vision. However, they are often associated with other signs of vitamin A deficiency, such as night blindness and dry eyes.
Causes
Bitot's spots are caused by a deficiency in vitamin A, a nutrient that is essential for maintaining the health of the eyes. This deficiency can occur as a result of malnutrition, malabsorption disorders, or certain diseases that affect the body's ability to absorb nutrients from food.
Treatment
Treatment for Bitot's spots involves correcting the underlying vitamin A deficiency. This is typically done through dietary changes or vitamin A supplements.
