Keratomalacia
Keratomalacia
Keratomalacia (pronounced: ker·a·to·ma·la·ci·a) is a medical condition characterized by the softening, thinning, and eventual perforation of the cornea due to severe vitamin A deficiency.
Etymology
The term "Keratomalacia" is derived from the Greek words "kerato," meaning cornea, and "malakia," meaning softening.
Symptoms
Symptoms of keratomalacia include night blindness, dry eyes, Bitot's spots, and in severe cases, corneal ulceration and perforation.
Causes
Keratomalacia is primarily caused by a severe deficiency of vitamin A, which is essential for the health of the eye. This deficiency can be due to malnutrition, malabsorption, or dietary restrictions.
Treatment
Treatment for keratomalacia involves the immediate administration of high-dose vitamin A, either orally or through injection. In severe cases, corneal transplantation may be necessary.
