E50.5
Vitamin A deficiency with night blindness
Clinical Classification Guidelines
Medical Intelligence & Overview
Vitamin A deficiency with night blindness, classified under ICD-10 code E50.5, is a nutritional condition where an insufficient intake or absorption of vitamin A leads to vision problems, particularly difficulty seeing in low light or darkness. Vitamin A plays a vital role in maintaining healthy vision, immune function, and cell growth. Deficiency of this essential nutrient can cause a range of health issues, but night blindness is often one of the earliest and most noticeable signs. Recognizing the symptoms and understanding the causes of vitamin A deficiency are crucial steps in preventing more severe complications associated with this condition.
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 which impair vitamin A storage and metabolism Chronic illnesses that increase nutrient demand or interfere with absorption Increased needs during pregnancy and lactation that are not met with adequate diet Alcoholism, which can impair vitamin absorption and metabolism
Key Symptoms: Night blindness — difficulty seeing in low light or darkness Blurred or decreased vision in dim lighting Dry eyes and corneal damage in severe cases Bitot’s spots — foamy, grayish patches on the conjunctiva Dry skin and mucous membranes Increased susceptibility to infections Delayed growth and development in children
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical assessment and laboratory testing. Healthcare providers may evaluate dietary habits, check for signs of deficiency, and perform eye examinations to detect early signs such as Bitot’s spots. Blood tests measuring serum retinol levels are commonly used to confirm a deficiency. In some cases, additional tests may be performed to assess the severity and underlying causes of the condition.
Treatment Protocols: Increasing intake of vitamin A-rich foods like liver, fish, dairy, carrots, sweet potatoes, and leafy green vegetables Vitamin A supplements prescribed by a healthcare professional to quickly replenish stores, especially in cases of severe deficiency Treating underlying causes such as malabsorption issues or liver conditions Monitoring and follow-up to ensure normalization of vitamin A levels and resolution of symptoms Addressing related nutritional deficiencies to support overall health
