In 71 cases of primary open-angle glaucoma and in 29 cases of angleclosure glaucoma a sinus trabeculoectomy was performed and the biopsy specimens were studied by light microscopy.

In glaucomatous eyes, Schlemm's canal was narrowed and in some cases obliterated. In eyes with open-…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
