Slit lamp photograph and AS-OCT of a Salzmann’s nodule and band keratopathy. a Slit lamp photograph of a central Salzmann’s nodule. b On AS-OCT, the nodule is seen as a localized area of hyperreflective material that has replaced the anterior stroma and Bowman’s layer underneath normal epithelium (arrow). c Slit lamp photograph of band keratopathy in the peripheral cornea (arrow). d AS-OCT imaging shows a thin band of hyperreflectivity along Bowman’s layer with underlying shadowing (arrow)
