Objectives
At the end of this session, participants will be able to:
- Discuss the Canadian glaucoma guidelines, focusing on key issues such as how dilating pupils change IOP, the rate of change of glaucoma depending on the type of optic nerve, and the myth that ALT is better than SLT for raised IOP in pseudoexfoliation.
- Describe the newer glaucoma medical therapies and where they fit into the treatment regimen.
- Integrate into practice an effective approach for dealing with patients with persistent high IOP after laser iridotomy and a new patients presenting with very high IOP.
