E50.6
Vitamin A deficiency with xerophthalmic scars of cornea
Clinical Classification Guidelines
Medical Intelligence & Overview
Vitamin A deficiency is a health condition caused by inadequate intake or absorption of vitamin A, an essential nutrient vital for maintaining healthy vision, immune system function, and cellular growth. When the deficiency becomes severe, it can lead to extensive damage to the eyes, including xerophthalmia, a condition characterized by dryness of the conjunctiva and cornea. Over time, this dryness can cause scarring of the cornea, potentially resulting in vision loss. The ICD-10 code E50.6 specifically refers to cases where a vitamin A deficiency has led to xerophthalmic scars of the cornea, highlighting a more advanced stage of eye damage due to vitamin deficiency.
Causes & Symptoms
Clinical Causes: Inadequate dietary intake of vitamin A-rich foods such as liver, dairy products, and orange or green vegetables Malabsorption syndromes including celiac disease, Crohn’s disease, or pancreatic insufficiency Liver disorders affecting vitamin A storage and mobilization Prolonged diarrhea or infections that impair absorption Increased needs during pregnancy, lactation, or periods of illness, which may not be met if dietary intake is insufficient Vitamin A supplementation deficiencies in regions where access to supplemental programs is limited
Key Symptoms: Night blindness (difficulty seeing in low light) Xerophthalmia, characterized by dryness and thickening of the conjunctiva Bitot's spots, which are foamy, keratinized patches on the conjunctiva Corneal xerosis, leading to dryness of the cornea Corneal ulceration or keratomalacia (softening of the cornea) Scarring of the cornea (xerophthalmic scars), which can impair vision Increased susceptibility to respiratory infections and other illnesses Lack of appetite and potential failure to thrive in children
Diagnostic & Treatment
Diagnosis Path: Diagnosis of vitamin A deficiency with corneal scarring involves a combination of clinical examination and medical history. Key diagnostic steps include: - Ophthalmic evaluation to identify signs like xerosis, Bitot's spots, or corneal scars - Dietary assessment to evaluate vitamin A intake - Blood tests measuring serum vitamin A levels to confirm deficiency - Additional testing for underlying causes such as malabsorption or liver issues - Visual acuity tests to assess the extent of vision impairment Further assessments may include fundoscopy to evaluate retinal health and rule out other ocular conditions.
Treatment Protocols: Treatment primarily focuses on replenishing vitamin A levels and preventing further ocular damage. Common approaches include: - Oral vitamin A supplementation dosed appropriately based on age and severity - Management of ocular surface dryness with lubricating eye drops or ointments - Treating underlying conditions that impair absorption or utilization of vitamin A - Educating patients on dietary sources rich in vitamin A, such as carrots, sweet potatoes, spinach, and animal liver - Regular follow-up to monitor visual function and prevent progression In severe cases, surgical intervention may be required to address corneal scarring or perforation, but the primary goal remains to restore and maintain adequate vitamin A levels.
