Normal pressure glaucoma can be very effectively treated with SLT (selective laser trabeculoplasty). The eye pressure can drop from 20mmHg down to as much as 8-10mmHg with laser. One issue with SLT is that some patients (approximately 1 in 20) may not respond to treatment, and the average drop in IOP is about 5-7mmHg - yet the treatment is safer than surgery and does not carry a risk of serious infection as with surgery.

Migraines are associated with visual disturbance and some patients experience "zig zag lines" and the sensation of flashing lights. Migraine is commoner in those with Normal Pressure Glaucoma.
