ABSTRACT
@#AIM: To evaluate the changes of anterior chamber structure in patients after combined surgery of glaucoma and cataract with viscoelastics injection under the sclera valve by OCT. <p>METHODS: The cataract with acute glaucoma patients who underwent combined surgery of glaucoma and cataract from 2016 to 2018 were enrolled. The patients were divided into the viscoelastics group and the control group. The anterior chamber depth(ACD), the angle opening distance(AOD<sub>500</sub>)and the trabecular iris angle(TIA)were examined to compare the changes of the anterior chamber structure between the two groups. <p>RESULTS: At 1 and 3d after surgery, the ACD(3.82±0.51,3.71±0.63, 3.78±0.33mm), the angle opening distance(AOD<sub>500</sub>: 0.25±0.04, 0.24±0.04, 0.25±0.05mm)and the TIA(25.13°±8.06°, 26.18°±8.06°, 29.25°±6.22°)were statistically different between two groups. There was no significant difference on the ACD, the AOD<sub>500</sub> and the TIA of the two groups 7d after surgery(<i>P</i><0.05).<p>CONCLUSION: Viscoelastics injection under the sclera valve can deepen the anterior chamber effectively after combined surgery of glaucoma and cataract. It avoids the occurrence of shallow anterior chamber in the early postoperation and maintains the opening of anterior chamber.
ABSTRACT
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.
