H16.21
Exposure keratoconjunctivitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Exposure keratoconjunctivitis is a condition that affects the surface of the eye, involving inflammation of the cornea and conjunctiva caused by exposure to environmental elements. It often results from inadequate eyelid closure or exposure to harsh environmental conditions, leading to irritation, redness, and discomfort in the eyes. Recognizing the symptoms and understanding the causes can aid in appropriate management and relief.
Causes & Symptoms
Clinical Causes: Incomplete eyelid closure (lagophthalmos) due to facial nerve palsy or eyelid paralysis. Exposure to wind, dust, smoke, or chemical irritants. Prolonged exposure in dry or windy environments. Post-surgical exposure resulting from eyelid or eye surgeries. Congenital eyelid abnormalities that hinder proper eyelid coverage.
Key Symptoms: Eye redness and inflammation Grittiness or sensation of foreign body in the eye Tearing and increased lachrymation Sensitivity to light (photophobia) Blurred vision or visual discomfort Pain or discomfort in the affected eye Dryness and irritation of the eye surface Crusting or discharge around the eyelashes
Diagnostic & Treatment
Diagnosis Path: Diagnosis is primarily clinical, involving a detailed eye examination by an eye care professional. The clinician assesses eyelid function, checks for incomplete eyelid closure, and observes signs of corneal and conjunctival inflammation. Additional diagnostic tests may include slit-lamp examination to evaluate the severity of surface damage and fluorescein staining to identify corneal epithelial defects. A thorough patient history helps identify potential exposure risks and environmental factors contributing to the condition.
Treatment Protocols: Management aims to protect the eye surface from further irritation and promote healing. Typical treatment strategies include:
