Purpose: To prognosticate patients of corneal edema with prospective diagnosis of herpes simplex(HSV) keratitis, by differentiating them into HSV stromal keratitis and HSV endothelitis using anterior segment optical coherence tomography (ASOCT) as a tool.
Materials: ASOCT was done in 25 patients of HSV keratitis with dense corneal edema to assess details and differentiate them into HSV stromal keratitis and endothelitis.
Results: 13 patients had endothelitis based on the presence of stromal edema with keratic precipitates on the endothelium whereas 12 patients had only stromal edema and so were diagnosed as having stromal keratitis.
Conclusion: Both HSV stromal keratitis and HSV endothelitis can present clinically with stromal opacity and, therefore, may be difficult to distinguish. ASOCT is a useful tool to differentiate between the two. Patients with endothelitis have poorer prognosis so need to be treated aggressively and followed up more closely
