ICD-10: H16.2

Keratoconjunctivitis, classified under ICD-10 code H16.2, encompasses a range of inflammatory conditions affecting both the cornea and conjunctiva of the eye. This condition can arise from various etiologies, including infections, allergies, and environmental factors. Below is a detailed overview of keratoconjunctivitis, including its clinical description, types, symptoms, and potential treatment options.

Clinical Description

Keratoconjunctivitis refers to the inflammation of the conjunctiva (the membrane covering the white part of the eye and the inner eyelids) and the cornea (the clear front surface of the eye). The ICD-10 code H16.2 specifically pertains to keratoconjunctivitis that is not further specified, indicating a general category for this condition without detailing the underlying cause.

Types of Keratoconjunctivitis

1. Allergic Keratoconjunctivitis: This type is triggered by allergens such as pollen, dust mites, or pet dander. It is characterized by intense itching, redness, and tearing.

2. Viral Keratoconjunctivitis: Often caused by adenoviruses, this form is highly contagious and typically presents with watery discharge, redness, and swelling.

3. Bacterial Keratoconjunctivitis: This type is caused by bacterial infections, leading to purulent discharge, redness, and discomfort. Common bacteria include Staphylococcus and Streptococcus species.

4. Keratoconjunctivitis Sicca (Dry Eye Syndrome): This condition results from insufficient tear production or excessive tear evaporation, leading to dryness, irritation, and inflammation of the conjunctiva and cornea.

5. Neurotrophic Keratopathy: This rare form occurs due to damage to the corneal nerves, often resulting in decreased sensation and subsequent corneal damage.

Symptoms

The symptoms of keratoconjunctivitis can vary depending on the underlying cause but commonly include:

• Redness of the eye
• Itching or burning sensation
• Watery or purulent discharge
• Sensitivity to light (photophobia)
