H18.443
Keratomalacia, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Keratomalacia, bilateral, is a condition characterized by the softening and ulceration of both corneas, the clear front surfaces of the eyes. This condition can significantly impair vision and, if left untreated, may lead to blindness. It is often linked to severe vitamin A deficiency and requires prompt medical attention to prevent serious ocular damage.
Causes & Symptoms
Clinical Causes: Severe vitamin A deficiency Malnutrition, especially in developing countries Chronic intestinal infections that impair vitamin absorption Prolonged diarrhea Certain medical conditions affecting nutrient absorption Inadequate dietary intake of vitamin A Lack of access to vitamin A supplementation in vulnerable populations
Key Symptoms: Night blindness (difficulty seeing in low light) Blurred vision Photophobia (sensitivity to light) Corneal dryness and ulceration Ocular pain or discomfort Corneal opacity or clouding Potential progression to corneal perforation if untreated
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination by an ophthalmologist, assessing the cornea for signs of softening, ulceration, or scarring. A detailed patient history focusing on nutritional status and vitamin A intake is also important. Additional blood tests may be performed to evaluate vitamin A levels. Imaging techniques or slit-lamp microscopy can provide detailed views of corneal health to confirm the diagnosis.
Treatment Protocols: Administering high-dose vitamin A supplementation, either orally or via injections Addressing underlying nutritional deficiencies through dietary improvements Use of topical antibiotics or ointments to prevent or treat secondary infections Supportive care to manage symptoms and protect the eye, such as lubricating eye drops In severe cases, surgical interventions like corneal transplantation may be necessary Regular follow-up with eye care specialists to monitor healing and prevent recurrences
