Figure 4: (a and b) A case of mixed corneal dystrophy of macular, granular, and lattice types. (a) The superficial corneal stroma showed myxoid and eosinophilic hyaline material, focally elevate the corneal epithelium (H and E, ×100). (c) The bluish mucopolysaccharide material at the superficial corneal stroma denoting macular corneal dystrophy (Alcian blue, ×100). (d) Mottled dark red (positive deposits) and pale bluish-to-greenish corneal stroma denoting hyaline corneal degeneration of granular corneal dystrophy (Masson's trichrome, ×100). (e) The orange red color of amyloid material in deep corneal stroma (Congo red, ×100). (f) The section was examined by the polarizing light and showed the characteristic apple green birefringence of amyloid deposits seen in lattice corneal dystrophy (Congo red ×100)
