Data was collected from charts of all PACD patients treated from April 2013 to December 2015. Analysis was done on 137 patient charts with complete biometric data. Patient demographics,PACD type,refractive status(spherical equivalent),ACD and AL were studied.RESULTS: The median age of 137 subjects [53 with primary angle-closure suspects(PACS),27 with primary angleclosure(PAC) and 57 with primary angle-closure glaucoma(PACG)] was 68y(range 21-88y). The majority was Chinese(n=68;49.6%) and most of them were women(n=75;54.7%). The distribution of myopia(n=51; 37.2%) and hyperopia(n=49;35.8%) was similar. The ACD was shallower in myopes compared to hyperopes(P=0.02) and emmetropia(P=0.049) but the AL was not significantly different between groups. There were no patients blind from PACG.CONCLUSION: Both myopia and hyperopia can occur in PACD. Despite a shallower ACD in angle closure myopes,the AL was not different between groups.展开更多

文摘Dear Editor,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,and headache.Delay in timely IOPlowering treatment can result in permanent optic nerve damage and vision loss.
