Primary angle closure glaucoma is a major cause of visual morbidity in Asia, which hosts 80% of the worldwide cases. In India, primary angle closure glaucoma (PACG) comprises almost 50% of adult glaucomas in hospital setting with its asymptomatic presentation predominating at 80%. Early diagnosis is critical to prevent the blinding trajectory of this disease, which is purported to cause twice as much blindness compared to open angle glaucoma. Traditional screening methods to identify PACG range from van Herick and flashlight test (relatively poor predictors) to gonioscopy (gold standard). Altered iris morphology are intrinsic to PACG, resulting in specific iris patterns. Iris appraisal could emerge as a method to screen underlying PACG. This would not only be specific, objective, but also easily performed at the peripheral level by a trained personnel and used in the era of tele-medicine for mass screening by AI softwares. This article seeks to detail these iris changes.
