Summary

Corneal biopsy aids diagnosis when standard scrapings fail for suspected microbial keratitis. This procedure is valuable for managing chronic keratitis cases lacking a specific microbiological diagnosis.

Area of Science:

Ophthalmology
Microbiology
Pathology

Background:

Diagnosing microbial keratitis can be challenging without definitive microbiological evidence.
Standard corneal scrapings may yield negative results, necessitating alternative diagnostic methods.

Observation:

Presents two clinical cases where corneal biopsy was instrumental in diagnosing microbial keratitis.
Highlights the utility of corneal biopsy in cases with negative corneal scrapings.

Findings:

Corneal biopsy successfully provided a diagnosis in presumed microbial keratitis cases.
Demonstrates the diagnostic value of corneal biopsy when initial microbiological investigations are inconclusive.

Implications:

Corneal biopsy should be considered in the management of chronic or difficult-to-diagnose keratitis.
