Bangkok: Verified information from the "Sure Before Sharing" center reveals crucial insights into the condition known as Bitot's Spot, a severe complication stemming from vitamin A deficiency that poses a risk to eye health. Assoc. Prof. Dr. Sakchai Wongkittirak, Chairman of Academic Affairs at the Royal College of Ophthalmologists of Thailand, sheds light on this condition and its implications.

According to Thai News Agency, Bitot's Spot is characterized by scale-like growths on the eyes due to a deficiency in vitamin A, which is essential for retinal function and tear fluid production. This deficiency leads to a significant decrease in eye lubrication, causing severe dry eyes and conjunctival thickening, manifesting as a cloudy white layer on the eye's surface.

The condition, though not immediately leading to blindness, results in eye irritation and can progress to more severe complications if untreated. Night blindness and corneal perforation are notable risks, historically contributing to blindness in Thai children.

Children are particularly vulnerable to the effects of vitamin A deficiency, making them more prone to developing blepharitis and corneal perforation. However, the prevalence of this condition has declined in Thailand due to improved dietary diversity.

Preventive measures underscore the importance of a balanced diet rich in vitamin A sources such as eggs, meat, leafy greens, and yellow/orange fruits and vegetables. Ophthalmologists advise against unnecessary vitamin A supplementation, highlighting that a balanced diet usually suffices in meeting nutritional needs.

In conclusion, maintaining a varied diet is the best defense against vitamin A deficiency and its associated eye health risks. Individuals experiencing severe dry eye symptoms are encouraged to seek professional medical advice for a proper diagnosis.
