Effect of Vitamin A Deficiency on Eyes
1. What is Vitamin A Deficiency?
Vitamin A deficiency occurs when your body doesn’t get enough vitamin A — an essential nutrient for maintaining healthy vision, especially night vision and corneal health. It’s one of the most common causes of preventable blindness in developing countries.
2. How does Vitamin A affect the eyes?
Vitamin A is vital for producing rhodopsin, a pigment in the retina that helps you see in dim light. It also maintains the surface tissues (cornea and conjunctiva) of your eyes. Without it, the eye’s protective layer dries and weakens, leading to infections and ulcers.
3. What are the early signs of Vitamin A deficiency?
- ● Night blindness (Nyctalopia): Difficulty seeing in dim or dark environments.
- ● Dry eyes (Xerophthalmia): Reduced tear production, causing irritation and discomfort.
- ● Bitot’s spots: White foamy patches on the conjunctiva.
- ● Corneal ulcers or scars in severe stages.
4. Who is at risk?
5. How is it diagnosed?
An ophthalmic examination can identify dryness or spots. In severe cases, special staining tests and nutrition assessment are done.
6. How is it treated?
- ● Vitamin A supplementation: Oral or injectable vitamin A given under medical supervision.
- ● Nutritional guidance: Diet rich in vitamin A — carrots, spinach, papaya, sweet potatoes, eggs, and fish.
- ● Lubricating eye drops to relieve dryness and protect cornea.
