Sohag University


Corneas of 10 rabbits and 50 human eyes were injected by Rottring China painting ink , the rabbits corneas were histologically examined and human eyes were clinically followed up.

Histological results of the stained rabbit corneas showed blackish pigmentation in the corneal stroma without any inflammatory cellular infiltration. Some fibroblast cells had pigment granules in their cytoplasm in the adjacent layers. in human eyes the Rotring painting ink was safe stable in colour with no faiding in the follow up period however insufficient staining with restaining was required in some patients
