Figure 1

Typical histological features of pterygium. Two serial tissue sections of pterygium were stained (a) with Haematoxylin-Eosin and (b) with periodic acid–Schiff (PAS) staining solutions. Red asterisks show goblet cells grouped as intraepithelial glands, while black asterisks show goblet cells randomly placed within pterygium epithelium. Black arrows show a rich vascular network, orange asterisks show inflammatory infiltrates. Original magnification: 10x.
