Corneal biopsy in chronic keratitis.

Area of Science:

• Ophthalmology
• Pathology
• Microbiology

Background:

• Chronic keratitis diagnosis is often difficult due to pathogen location or prior treatments.
• Identifying the causative agent is crucial for effective chronic keratitis management.

Purpose of the Study:

• To highlight the utility of lamellar keratectomy biopsy in diagnosing chronic keratitis.
• To emphasize the importance of ophthalmic pathologist consultation for specimen handling.

Main Methods:

• Lamellar keratectomy biopsy for obtaining corneal tissue.
• Histopathologic evaluation including histochemistry and immunohistopathology.
• Electron microscopy if necessary.
• Cultures for microbial identification.

Main Results:

• Biopsy provides sufficient tissue for comprehensive histopathologic and microbiologic analysis.
• Consultation with ophthalmic pathologists ensures proper specimen handling.
• Rapid pathogen identification is achievable within 24 hours of biopsy.

Conclusions:

• Lamellar keratectomy biopsy is an effective method for diagnosing chronic keratitis.
• Prompt diagnosis facilitates timely and appropriate therapeutic interventions.
• Multidisciplinary approach involving ophthalmologists and pathologists improves diagnostic yield.
