The authors estimated the age-related prevalence and number of patients, and incidence of various types of glaucoma in Japan. Four reports dealing with the prevalence of glaucomas were analyzed using an SAS mixed procedure. The prevalence of primary open-angle glaucoma (POAG), normal-tension glaucoma (NTG) and open-angle glaucoma (OAG), which comprises both POAG and NTG, increased with age; that of ocular hypertension decreased with age. The incidence of new cases of OAG gradually decreased with age. The total number of OAG patients between 40 and 74 years of age was estimated at 1,490,000 and its prevalence at 2.66% of the general population in Japan. This prevalence lay between that of Caucasians and of persons of African ancestry. The above findings show that it is possible to statistically analyze the reported data on epidemiological features of glaucoma and that the results could serve as a basis for medical care planning.
