Subepithelial corneal infiltrates often follow adenoviral keratoconjunctivitis. They usually resolve over time, but in some, these can progress to permanent corneal scars. Anterior segment- optical coherence tomography (S-OCT) can be a very useful tool to differentiate reversible infiltrates from irreversible scars and obviates the need for a steroid trial.
Subepithelial corneal infiltrates [Figure 1]a appear on AS-OCT patchy, anterior stromal hyperreflective lesions with an intact Bowman's membrane and a uniform epithelial thickness [Figure 1]b. On the other hand, scars [Figure 1]c on AS-OCT appear as hyperreflective plaque-like lesions in the anterior stroma with disruption of the Bowman's membrane and variable epithelial thickness due to epithelial remodeling [Figure 1]d.
