H16.243 Ophthalmia nodosa, bilateral

Name of the Condition

• Ophthalmia nodosa, bilateral

Summary

Ophthalmia nodosa is an inflammatory condition of the eye caused by the presence of foreign bodies, typically insect parts or plant material, embedded in the ocular tissues. It may result in redness, irritation, and potential tissue damage if not addressed. Prompt evaluation is important to identify and remove the foreign material and prevent complications.

Causes

The condition is caused by the introduction of foreign bodies, such as insect hairs, setae, or plant fragments, into the eye. These materials can penetrate the conjunctiva or cornea, triggering an inflammatory response. Exposure to environments with insects or plants that have irritating structures increases the risk of this condition.

Risk Factors

• Occupational or recreational exposure to insects or plants with irritating parts.
• Lack of protective eyewear in environments with potential foreign body hazards.
• Activities involving close contact with vegetation or insect colonies.

Symptoms

• Redness and swelling of the eye.
• Itching, burning, or gritty sensation.
• Excessive tearing or discharge.
• Sensitivity to light.
• Feeling of a foreign body in the eye.
• Possible visible or palpable foreign material in the eye.

Diagnosis

Diagnosis involves a comprehensive eye exam, including slit-lamp microscopy to identify foreign material. Additional tests, such as fluorescein staining, may be used to assess corneal involvement. A detailed patient history of recent exposure to potential irritants is also critical.

Treatment Options

Treatment focuses on removing the foreign material, often with irrigation or careful extraction under magnification. Topical antibiotics or anti-inflammatory medications may be prescribed to prevent infection and reduce inflammation. Pain management and follow-up care are typically recommended.

Prognosis and Follow-Up

With prompt removal of the foreign body and appropriate treatment, the prognosis is generally good. However, delayed intervention may lead to complications such as corneal scarring or infection. Follow-up appointments are important to monitor healing and address any persistent symptoms.

Complications

Potential complications include corneal abrasions, infections, or chronic inflammation. In severe cases, vision impairment may occur if the foreign material causes significant tissue damage.

Lifestyle & Prevention

Preventive measures include wearing protective eyewear in environments with potential irritants, avoiding direct contact with insects or plants known to have irritating parts, and practicing good hand hygiene to reduce eye rubbing.

When to Seek Professional Help

Seek medical attention if symptoms persist after initial self-care, if there is visible foreign material in the eye, or if there is severe pain, vision changes, or signs of infection such as increased discharge or swelling.

Tips for Medical Coders

Document the bilateral nature of the condition and any associated symptoms or complications. Ensure clinical documentation supports the diagnosis and treatment provided. Note the presence of foreign material and any removal procedures performed.
