Spectral domain anterior segment optical coherence tomography in microbial keratitis.
OBJECTIVE
To investigate the spectral domain anterior segment optical coherence tomography (SDAS-OCT) patterns in microbial keratitis (fungal and bacterial keratitis).


METHODS
Prospective, cross-sectional, observational study.


METHODS
Twenty eyes of 20 patients with proven fungal and bacterial microbial keratitis, at different stages of the disease, underwent SDAS-OCT imaging.


RESULTS
Eight eyes presented with proven bacterial keratitis (3 Staphylococcus Aureus, 2 Pseudomonas Aeruginosa and 3 Staphylococcus Epidermidis). Twelve eyes presented with proven fungal keratitis of Aspergillus species. Twelve different SDAS-OCT presentations of fungal and bacterial keratitis were found in this study. Our findings in fungal keratitis grasped two unique patterns of early localized and diffuse necrotic stromal cystic spaces.


CONCLUSIONS
SDAS-OCT imaging provided a range of characteristic patterns that could be used as an additional tool in diagnosis and management of bacterial and fungal microbial keratitis.
