Darkly pigmented mass approximately 15 mm wide at the dorsal limbus (yellow arrow), extending 6 mm into the cornea within the stroma, causing this area of the cornea to be elevated 5–7 mm higher than the adjacent corneal tissue. Diffuse pigmentation can be seen extending into the cornea from along the leading edge of the mass (red arrow). A distinct cresent-shaped arc of corneal edema delineates the edge of the mass within the cornea.
