, which the GRF notes is quick to develop, results when the drainage canals are blocked, resulting in a sudden rise in intraocular pressure.
In 2002, the International Society of Geographical and Epidemiological Ophthalmology (ISGEO) proposed a new definition and classification system of PACG
, in which the traditional PACG
was classified into three subtypes: (1) primary angle-closure suspect (PACS), (2) primary angle closure (PAC), and (3) PACG
(7,8,9) Detailed anterior chamber angle (ACA) evaluation is essential for the diagnosis of PACG
(9) The study showed that lens extraction showed less need for drops and was more cost-effective than LPI as a first-line treatment for patients with PAC or PACG
Patients could be divided into four groups in our study: primary open-angle glaucoma (POAG) (10/61; 16.4%), primary angle closure glaucoma (PACG
) (18/61; 29.5%), neovascular glaucoma (NVG) (29/61; 47.5%), and traumatic glaucoma (4/61; 6.6%).
 In contrast to this, Sharma et al  found more number of patients with PACG
in their study.
5, 6 Same was found in patients with chronic PACG
by Hong S et al., who found thin corneas showing more progression in VF defects.
was more prevalent in female gender as compared with male gender (4.81% vs.
Late presentation in POAG and PACG
is common (Gogate, Deshpande, Chelerkar, Deshpande, & Deshpande, 2011).
London, September 5 ( ANI ): Singapore scientists have identified three new genes associated with Primary Angle Closure Glaucoma (PACG
), a leading cause of blindness.
Singapore, Sept 3, 2012 - (ACN Newswire) - Singapore scientists have identified three new genes associated with Primary Angle Closure Glaucoma (PACG
), a leading cause of blindness in Chinese people.
A study was undertaken on 30 patients (25 male and 5 females; mean age at onset of disease being 59.23 years) of primary open angle glaucoma (POAG) and similar no (sixteen male and 14 females; mean age at onset of disease being 54.10 years) primary angle closure glaucoma (PACG
) for (i) analyzing mutations in myocilin (MYOC) gene, (ii) inheritance pattern of MYOC gene, (iii) comparing the frequency of MYOC gene in northern and southern population, and (iv) detect genotype and phenotype correlation based on mutations.
