Due to the high risk of optic nerve damage, most ophthalmologists treat if pressures are consistently above 28-30 mm Hg. If treatment is based on a high IOP only, then it should be ensured that the risks of treatment do not exceed the risk of the disease. Other reasons to treat include such symptoms as halos, blurred vision, or pain, or recent elevation of IOP, with continuing elevation on successive visits.

Initiation of a monocular trial (see Medication) may be useful in helping to decide whether or not to treat (ie, if the medication is effective in achieving good pressure reduction without adverse effects, which may argue in favor of treatment, instead of just observation).
