2023年11月26日 · Acute angle-closure glaucoma is an ocular emergency that results from a rapid increase in intraocular pressure due to outflow obstruction of aqueous humor. Several factors lead to the obstruction in acute angle-closure glaucoma, but the major predisposing factor is the structural anatomy of the anterior chamber, leading to a shallower angle ...

The basic principles of treatment of acute angle-closure are as follows: Treat acute attack. Break pupil block (pilocarpine, aqueous suppressants (by opening the angle) and indentation). Control IOP. Treat inflammation. Prevent future attacks with peripheral iridotomies. Detect and control ongoing glaucomatous optic neuropathy. CASE STUDY

原发性闭角型青光眼（primary angle closure glaucoma，PACG）是由原发性房角关闭所导致的急性或慢性眼压升高，造成视盘改变和视野损伤的一组疾病。 近年关于PACG的研究取得了新的进展，为此中华医学会眼科学分会青光眼学组以眼科循证医学为基础，经过充分讨论，对我国PACG的分类体系和诊断方法以及治疗原则达成进一步共识性意见，以供临床医师在对青光眼进行诊断和治疗时参考使用。 近年针对PACG的研究取得了新的进展。 研究发现PACG的发生和发展与虹 …

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 · PACG can be classified according to the timing or suddenness of onset into acute PACG or chronic PACG. The clinical course of acute PACG can be further divided into preclinical, attack (including acute, subacute or intermediate attacks), intermittent, chronic progression, and absolute stages according to the symptom and signs ( Ji et al., 1966 ...

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.

原发性闭角型青光眼(primary angle closure glaucoma，PACG)常见于亚洲，其中急性闭角型青光眼(acute primary angle－closure glaucoma，APACG)在亚洲的发病率高于欧美，而不同的分类、定义可能会导致不同的调查结果。

2023年2月11日 · Acute PACG is an ocular emergency that can have a profound impact on vision. It may lead to irreversible visual impairment if not treated as soon as possible. Thus, identifying this condition and immense management is important to prevent optic neuropathy.

The disease can be classified into primary angle-closure suspect, primary angle closure (PAC), and PACG. Pupil-block, anterior nonpupil-block (plateau iris and peripheral iris crowding), lens related and retrolenticular mechanisms have been suggested as the four main mechanisms of …

Acute primary angle-closure glaucoma (PACG) is an important cause of blindness in East Asia. 1 It is estimated that the overall prevalence of PACG will increase from 1.44% to 2.01% from 2020 to 2050. 2 Acute PACG is typically related to increased high intraocular pressure (IOP), with symptoms including red eye, blurred vision, nausea, vomiting ...
