Canadian perspectives in glaucoma management: setting target intraocular pressure range.

There is an abundance of evidence from recent randomized clinical trials showing that lowering the IOP is beneficial to the optic nerve and visual field. Setting and achieving a target IOP range is in keeping with evidence-based medicine. The benefits of reaching this target must be weighed against the risks of the treatment itself. Target IOP is a dynamic concept, needing constant reevaluation. What is lacking are established guidelines for determining the target IOP range that can be used in general ophthalmology practice.
