Clinical Report: Utilizing In Vivo Confocal Microscopy and Optical Coherence Tomography for the Assessment of Corneal Infections
Overview
This study evaluates the use of in vivo confocal microscopy (IVCM) and anterior segment optical coherence tomography (AS-OCT) in diagnosing severe infectious keratitis (IK). The findings highlight the potential of these imaging modalities to enhance diagnostic accuracy and treatment monitoring.
Background
Infectious keratitis is a leading cause of blindness globally, necessitating early diagnosis to prevent complications. Traditional diagnostic methods, such as slit lamp microscopy and culture, may be complemented by advanced imaging techniques like IVCM and AS-OCT, which offer detailed insights into corneal pathology.

Key Findings
IVCM provides cellular-level imaging with a resolution of 1.5–4 μm.
IVCM can visualize invading organisms with high sensitivity and specificity.
OCT is limited by back shadowing in dense infiltrates.
Deep learning models show promise for IK diagnosis but face challenges in real-world application.
Clinical Implications
The integration of IVCM and AS-OCT in clinical practice may improve the diagnostic process for infectious keratitis, allowing for better monitoring of treatment responses. Clinicians should be aware of the operator-dependent nature of these imaging modalities.
Conclusion
The study underscores the utility of IVCM and AS-OCT in enhancing the diagnosis and management of infectious keratitis, potentially leading to improved patient outcomes.
