From A. Neetens, University Hospital, Antwerp
In your article on eye drops, you talk of, “an antiglaucoma drug called dexamethasone” (Technology, 22 April). This is incorrect: detamethasone is a provocative test to detect the phenotypes in glaucoma families. The test is well-known and in the 1950s we were the first to publish the finding that applying steroids such as dexamethasone can actually increase intra-ocular pressure in glaucoma patients.
I am not commercially interested and write this letter only to raise the standards of this otherwise excellent article.
