We used the TV as the medium, and developed a 90-second commercial. We announced the date of the commercial in newspaper ads and put up posters in eye clinics, and drew potential patients to see the 90-second commercial. The campaign started with the support of the Japan Ophthalmology Association, to which 80 ophthalmologists belong.

80,000 prospective patients consulted eye clinics after seeing the commercial. Among them, 50% were diagnosed with NTG. Besides the commercial, special reports were created by TV stations, and leaflets were distributed in eye clinics. We were able to give out 1,000,000 leaflets in total.
