DIAGNOSIS
Diagnosing keratomalacia involves a comprehensive eye examination by an ophthalmologist, including:
- Visual Acuity Testing: Assessment of visual acuity using standardized eye charts to determine the extent of vision loss.
- Slit-Lamp Examination: Detailed examination of the cornea, conjunctiva, and anterior chamber of the eye using a slit lamp to detect corneal ulcers, opacities, or other abnormalities.
- Medical History: Inquiring about dietary habits, medical conditions, and symptoms suggestive of vitamin A deficiency or ocular pathology.
- Blood Tests: Measurement of serum vitamin A levels to confirm deficiency and assess the severity of malnutrition.
TREATMENT
Treatment of keratomalacia focuses on correcting the underlying vitamin A deficiency and managing ocular complications. Treatment options may include:
- Vitamin A Supplementation: Oral or parenteral administration of vitamin A supplements to replenish deficient levels and promote corneal healing and regeneration.
- Topical Lubricants: Eye drops or ointments containing lubricating agents to alleviate dryness, discomfort, and promote epithelial healing.
- Antibiotic Therapy: Topical or systemic antibiotics may be prescribed to prevent or treat secondary bacterial infections associated with corneal ulceration.
- Surgical Intervention: In severe cases of keratomalacia with extensive corneal scarring or perforation, surgical procedures such as corneal transplantation (keratoplasty) may be necessary to restore vision and ocular integrity.
Keratomalacia is a serious eye condition resulting from vitamin A deficiency, characterized by corneal degeneration, ulceration, and visual impairment. Early recognition and treatment of keratomalacia are essential to prevent irreversible damage to the cornea and preserve vision.
