Should anterior segment imaging devices replace gonioscopy?

ABSTRACT

@#Glaucoma will continue to be the leading cause of irreversible blindness worldwide.1,2 A recent metaanalysis done by Tham and coworkers projected an increase of 74% in the total number of people with glaucoma, from 64.3 million in 2013 to 76 million by 2020, and to 111.8 million by the year 2040.2 With this recent forecast, Asia will have the greatest number of both primary open angle glaucoma and primary angle closure glaucoma (PACG), comprising 18.8 million (79.8%) and 9 million (58.4%) respectively.2 Since half of the world’s PACG will come from Asia, an effective reduction in the real incidence and prevention of visual loss from this devastating disease will depend on the accurate assessment of the anterior chamber angle and early detection of appositional closure
