Interventions/Control_1

The subjects are instilled the 0.0015% tafluprost ophthalmic solution once a day for 36 months. The subjects are visited a hospital at every 3 month intervals and measured intraocular pressure and examined anterior segments of the eye. Visual field is measured at every 6 months interval after treatment of medicine.

Interventions/Control_2

The subjects are instilled the 0.005% latanoprost ophthalmic solution once a day for 36 months. The subjects are visited a hospital at every 3 month intervals and measured intraocular pressure and examined anterior segments of the eye. Visual field is measured at every 6 months interval after treatment of medicine.
