E50.3
Vitamin A deficiency with corneal ulceration and xerosis
Clinical Classification Guidelines
Medical Intelligence & Overview
Vitamin A deficiency is a health condition that occurs when the body doesn't get enough vitamin A, an essential nutrient vital for maintaining healthy vision, immune function, and skin health. When this deficiency becomes severe, it can lead to serious eye problems such as corneal ulceration and xerosis, which can threaten vision if left untreated. This condition is classified under ICD-10 code E50.3. Recognizing its causes, symptoms, and potential treatments can help in managing and preventing its serious complications.
Causes & Symptoms
Clinical Causes: Inadequate dietary intake of vitamin A-rich foods such as liver, carrots, sweet potatoes, and leafy greens. Malabsorption syndromes like celiac disease or Crohn's disease that impair vitamin absorption. Chronic diarrhea or pancreatic insufficiency reducing vitamin A absorption. Liver diseases that impair vitamin A storage and metabolism. Increased nutritional requirements during pregnancy, lactation, or periods of rapid growth. Certain medical conditions or medications that interfere with vitamin A metabolism.
Key Symptoms: Initial signs of vitamin A deficiency include night blindness, where vision is poor in low light conditions. Bitot's spots — foamy, white patches on the conjunctiva of the eye. Dryness of the conjunctiva and cornea, leading to xerosis. Corneal ulceration, which manifests as an open sore on the cornea's surface, potentially causing pain and blurred vision. Keratinization of the conjunctiva and cornea, resulting in dry, rough, or scaly eye surfaces. In severe cases, complete blindness due to corneal scarring or perforation. Additional symptoms may include dry skin and mucous membranes, increased susceptibility to infections, and general fatigue.
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a thorough medical history review and physical examination focused on eye health. Specific laboratory tests can assess vitamin A levels in the blood, although these are not routinely performed. Ophthalmic examinations are crucial for identifying characteristic signs such as Bitot's spots, corneal changes, and ulceration. In some cases, ophthalmologists may use slit-lamp examinations to evaluate the extent of corneal damage. Detecting underlying causes, including malabsorption or nutritional deficiencies, is also an essential component of diagnosis.
Treatment Protocols: Managing vitamin A deficiency involves replenishing vitamin A stores and addressing underlying causes. Treatment options include:
