A new method to treat NVG: Cyclophotocoagulation by sclera depress with non-contact wide angle surgical system (with operation video)

The treatment of neovascular glaucoma aims at controlling IOP, saving vision and enhancing visual function. PDR and RVO are main reasons of NVG. Endoscope treatment introduces seriously intraoperative injury. Comparing with traditional and endoscope treatment, vitrectomy (23G/25G) with cyclophotocoagulation by sclera depress using non-contact wide angle surgical system to cure NVG can significantly reduce intraoperative injuries, meanwhile this method shows widespread availability.

This study includes 36 eyes from 27 NVG patients. 10 eyes of these cases were RVO and 26 eyes were PDR. All cases were treated NVG with vitrectomy (23/25G) and  cyclophotocoagulation by sclera depress with non-contact wide angle surgical system. BCVA in logMar, IOP and anterior segment neovascularization were evaluated. At postoperative 1 and 3 months, BCVA was improved from 0.04±0.126 to 0.18±0.231 and 0.18±0.412; IOP was declined from 69.28±22.53mmHg to 15.79±1.38 and 23.21±3.94, respectively. At postoperative one-month, 95% patients can control the IOP well and anterior segment neovascularization of all cases subsided.

Cyclophotocoagulation by sclera depress with non-contact wide angle surgical system is a safety and practical method to treat NVG.
