In cases where diffuse interstitial keratitis leads to significant corneal scarring or vision loss, a corneal transplant (keratoplasty) may be considered. This procedure involves replacing the damaged cornea with donor tissue. The decision for surgery is typically based on the extent of corneal involvement and the patient's overall health[4].

Punctal Occlusion

For patients experiencing significant dry eye symptoms due to keratitis, punctal occlusion may be performed. This procedure involves blocking the tear ducts to retain moisture on the ocular surface, providing symptomatic relief[5].

3. Follow-Up and Monitoring

Regular follow-up appointments are essential to monitor the progression of the disease and the effectiveness of treatment. Adjustments to the treatment plan may be necessary based on the patient's response and any side effects experienced.

Conclusion

The management of diffuse interstitial keratitis (ICD-10 code H16.321) involves a combination of medical and surgical approaches tailored to the underlying cause and severity of the condition. Early intervention with topical corticosteroids, appropriate antimicrobial therapy, and supportive measures can significantly improve outcomes. In more severe cases, surgical options such as corneal transplantation may be warranted. Continuous monitoring and follow-up are crucial to ensure optimal recovery and prevent complications.
