Figure 2

Toluidine blue staining of pterygium and conjunctiva: mast cells showed the specific violet staining. (a, b) Typical photos of toluidine blue staining of mast cells in conjunctiva (a) and pterygium (b). (c, d) Typical photos of toluidine blue staining of intact mast cells (c) and degranulated mast cells (d). (e) The numbers of total mast cells and degranulated mast cells per mm² counted in 15 random fields of microscope: both the numbers were greater in pterygium than in conjunctiva. compared to conjunctiva.
