International Eye Science 2014;(8):1508-1510
AIM: To compare the effect of trabeculectomy and combined surgery of glaucoma and cataract treating primary angle-closure glaucoma ( PACG) with cataract. METHODS: It was retrospectively reviewed that 80 patients (90 eyes) with PACG and cataract were treated in our hospital from January 2012 to October 2013. They were divided into observation group ( combined surgery of glaucoma and cataract group, 45 eyes ) and control group ( trabeculectomy group, 45 eyes) . Postoperatively, all the patients were followed up for 6mo. Intraocular pressure ( IOP ) , visual acuity and complications were observed.
RESULTS: Compared to preoperative IOP, postoperative IOP was significantly reduced in both observation group and control group, while IOP was reduced more greatly in observation group (P=0. 003). Visual acuity was significantly improved in observation group, while it was not improved significantly in control group ( P = 0. 036 ). Compared to control group, complications such as shallow anterior chamber with hypotony, macular edema and anterior chamber inflammation were less observed in observation group, with significant statistical difference ( P=0. 002, P=0. 003, P=0. 001).
CONCLUSION: For patients with PACG and cataract, combined surgery of glaucoma and cataract is an effective surgery that can improve visual acuity and reduce IOP with fewer complications.

Developmental dyslexia is a specific learning disability. The cerebral mechanism of development dyslexia is an important topic that has fascinated many researchers. With the introduction of brain imaging in studies of cerebral mechanism of development dyslexia, many achievements have been made. Studies of developmental dyslexia structure image found that development dyslexia showed brain structure abnormal in the parietotemporal region, occipitotemporal cortex, inferior frontal gyrus, and cerebellum et al, manifesting either in one specific area or by the asymmetry of one area; the functional image studies revealed that development dyslexia showed activity abnormal in most regions that proved to display structure abnormality; studies of brain functional connectivity demonstrates that the abnormality of development dyslexia happened not only in the connection between front-back part in one cerebral hemisphere, but also in the connection between the two hemispheres. In addition, some studies indicate Chinese development dyslexia has different brain mechanisms compared to that of alphabetic languages. These findings provide valuable insight for future developmental cerebral mechanisms research and for the expansion of Chinese development dyslexia research.
