—I think Drs. Davis and Chandler are right as far as they go, but they say "one recent text" correctly identified these substances, without mentioning that I made it all very clear in my Toxicology of the Eye.Further, the authors should give attention to the article by Berman and Manabe (Ann Ophthalmol 5:1193, 1973) in which they give evidence that not only calcium but zinc is involved in the activity of some collagenases, and in this context, one might use either calcium or sodium EDTA.
