07Jun2011 from talk given 26Jun2010 1730hrs presented at the COS Annual Meeting in Quebec City by Dr Ike Ahmed. This is the last of the 201 COS glaucoma articles to be posted and just in time for the COS 2011 articles to begin to appear. Look for them in the months ahead as they will slowly apear as I finish editing them. Please note that the focus of the COS 2011 Glaucoma talks was on surgical treatment so there will be newer information on that portion of the blog.
