Question

What is Keratomalacia​

Answer 1

Keratomalacia is a medical condition that affects the cornea, which is the clear, dome-shaped outermost layer of the eye. It is a severe form of vitamin A deficiency that can lead to irreversible damage to the cornea, causing it to become soft and thin.

In keratomalacia, the cornea loses its transparency and becomes opaque, which can result in vision loss or blindness. The condition usually occurs in malnourished individuals, particularly in developing countries where there is a lack of access to foods that are rich in vitamin A.

Symptoms of keratomalacia may include night blindness, dry eyes, redness, and ulcers on the cornea. Treatment typically involves administering high doses of vitamin A supplements to correct the deficiency and prevent further damage to the cornea. In severe cases, surgery may be necessary to restore vision.

Answer 2

Answer:

Keratomalacia is a medical condition characterized by the dryness, softening, and ulceration of the cornea, the transparent front part of the eye. The condition is caused by severe deficiency of vitamin A, which is essential for maintaining the health of the eyes and the skin.

Keratomalacia is a serious condition that can cause permanent damage to the eyes, including blindness. It is most commonly seen in children in developing countries who have a diet deficient in vitamin A, but can also occur in adults with certain medical conditions that affect the absorption of nutrients, such as cystic fibrosis, inflammatory bowel disease, and liver disease.

Symptoms of keratomalacia include night blindness, dryness and redness of the eyes, sensitivity to light, and eventually, the development of corneal ulcers that can lead to blindness if left untreated. Treatment typically involves high-dose vitamin A supplements, along with management of any underlying medical conditions.
