Relative pupillary block is thought to account for >90% cases of primary angle closure (PAC) and primary angle-closure glaucoma (PACG) in East Asians. Plateau iris is an important cause of PAC and PACG in up to 30% of Chinese patients.

2017年10月28日 · The researchers assessed the efficacy, safety, and cost-effectiveness of clear lens extraction versus laser peripheral iridotomy for the first-line treatment of PACG and PAC. Inclusion criteria for patients were: age 50 years or older, absence of cataract, and mild or moderate PACG or newly diagnosed PAC with IOP of 30 mm Hg or greater.

Primary angle closure glaucoma (PACG) is a chronic optic neuropathy associated with a loss of retinal ganglion cells and their axons. Pupil block is the most common cause. Patients with angle closure disease are typically asymptomatic until the condition becomes more advanced.

Primary angle closure (PAC) – An eye that has a primary anatomic narrow angle and evidence that trabecular obstruction by the peripheral iris has occurred, such as peripheral anterior synechiae (PAS), elevated IOP, iris whorling or sectoral atrophy, and excessive pigment deposition on the trabecular surface.

2013年12月18日 · Acute angle closure is an urgent but uncommon dramatic symptomatic event with blurring of vision, painful red eye, headache, nausea, and vomiting. Diagnosis is made by noting high intraocular pressure (IOP), corneal edema, shallow anterior chamber, and a closed angle on gonioscopy.

2017年3月1日 · Primary angle-closure glaucoma (PACG) is a common cause of blindness. Angle closure is a fundamental pathologic process in PAGC. With the development of imaging devices for the anterior segment of the eye, a better understanding of the pathogenesis of angle closure has been reached.

Although primary open angle glaucoma (POAG) affects three times as many people globally, the absolute number of people blinded by glaucoma is equally split between POAG and primary angle-closure glaucoma (PACG). Over 1 million people in Europe and 160,000 people in the UK have PACG causing visual field loss.

Primary angle-closure glaucoma (PACG) is a common cause of blindness. Angle closure is a fundamental pathologic process in PAGC. With the development of imaging devices for the anterior segment of the eye, a better understanding of the pathogenesis of …

2009年9月14日 · Primary angle closure glaucoma (PACG) is a leading cause of blindness worldwide. In China, it is estimated that nearly one in six individuals over the age of 50 has an angle appearance that puts him/her at risk of PACG and acute angle closure attacks.

Primary angle-closure glaucoma (PACG) is estimated to affect over 30 million people worldwide by 2040 and is highly prevalent in the Asian population. PACG is more severe and carries three times the higher risk of blindness than primary open-angle glaucoma, thus representing a significant public health concern.
