Slit lamp and HR-OCT images and histopathology of conjunctival amyloidosis. a Slit lamp photograph of a 66-year-old male who presented with a gelatinous lesion on the bulbar conjunctiva on the left eye (black arrow). b HR-OCT through the lesion revealed a normal epithelial layer with a heterogeneous, subepithelial lesion with several hyperreflective opacities (white arrows). c Paucicelluar amorphous material consistent with amyloid was present within the substantia propria (black arrow) (hematoxylin and eosin; original magnification × 100). d The amyloid material demonstrates apple-green birefringence (white arrow) (Congo red; original magnification × 100)
