Glaucoma is the leading cause of blindness in Japan.*3 According to a detailed glaucoma epidemiological study (the Tajimi Study) conducted between 2000 and 2002, there are an estimated 4.65 million glaucoma patients in Japan (calculated based on 2016 demographics). Furthermore, in the same study, the rate of new glaucoma detection was 89%, which suggests that many patients are untreated.
Patients need to visit their hospital once a month for two months after being diagnosed with glaucoma, and once every two-to-three months from the third month onward. The challenge is how to encourage patients to continue their treatment. In Japan, one survey showed that about 40% of patients have discontinued their treatment after one year. *4
