Abstract:

Prevalence of primary angle closure glaucoma (PACG) is higher in Asia. The incidence of acute primary angle-closure glaucoma (APACG) in Asia is higher than in the Euro-American countries. These studies proved that APACG has a strong association with gender, age, race and ocular anatomy. The incidence in APACG is from 2.0/100000 to 8.3/100000 in Europe and America, and from 10.4/100000 to 12.2/100000 in Asian countries. The incidence in female were more than this in male, and the incidence increased with age. The prevalence of blindness in PACG was higher than that in primary open angle glaucoma. In addition, the blindness rate of APACG was related to duration of symptoms before presentation. Therefore, there is great clinical implication to explore the way to reduce the blindness caused by APACG.  (Int Rev Ophthalmol, 2018, 42: 73-77)
