• A new technique is presented using impression of the conjunctiva with a plastic device to study the conjunctival response in various conjunctival disease states. When used with a rapid acting stain the impression technique proved to be accurate, reproducible, and nondestructive when compared to the standard spatula scraping of the conjunctiva using Giemsa stain.
