In vivo conjunctival epithelial healing in albino rabbits was investigated by light microscopy following both n-heptanol and trephined conjunctival wounding. Reepithelialization occurred faster following n-heptanol treatment (3 days) versus trephination (6-7 days). No goblet cells were present in the migrating epithelium during reepithelialization. After 1 day of wounding, goblet cells disappeared several millimeters peripheral to the wound margin in both types of wounds. Goblet cells first reappeared peripherally 1 week after wounding before they appeared in the central wound area. These observations indicate that a large area of conjunctival epithelium surrounding a wound is involved with repair of that wound. Since the goblet cell content of conjunctival epithelium appears to change as a result of the stresses of epithelial repair, the goblet cell population may reflect the presence of reparative or proliferative processes in the ocular surface.
