Abstract: Purpose To investigate the spectral domain anterior segment optical coherence tomography (SDAS-OCT) parameters in microbial keratitis. Design Prospective, cross-sectional, observational study. Methods Thirty eyes of 30 patients with proven microbial keratitis (fungal, bacterial and viral), at different stages of the disease, underwent SDAS-OCT imaging. Results 12 eyes were diagnosed with proven fungal keratitis, 10 eyes with proven bacterial keratitis and 8 eyes with proven of viral keratitis. Different types of SDAS-OCT presentations of microbial keratitis were found in this study. Conclusion SDAS-OCT imaging provided a range of characteristic patterns that could be used as an additional tool in management and assessing the response to treatment of microbial keratitis.
