The efficiency of endoscopic cyclophotocoagulation in the treatment of refractory glaucoma after vitrectomy

Objective To evaluate the efficacy of endoscopic cyclophotocoagulation(ECP)in the treatment of glaucoma after vitrectomy.Methods Clinical data of 31 eyes of 30 cases with refractory glaucoma after vitrectomy who received ECP from May 2015 to Dec.2017 in Shanxi Eye Hospital were analyzed retrospectively.Patients were grouped as<180°group with 12 eyes,180°-270°group with 5 eyes,and>270°group with 14 eyes based on the range of ECP.The IOP after surgery,visual acuity at last follow-up and the relationship between different photocoagulation range and postoperative intraocular pressure drop were observed.Results At every time points after surgery,the IOP significantly decreased(F=26.82,P<0.05).The greater the range of photocoagulation,the more effective it was by lowering intraocular pressure.Both of the above were related positively to each other.After surgery,the IOP without anti-glaucoma drugs was normal in 22 cases(70.97%)and abnormal in 7 cases(22.58%)with the application of anti-glaucoma eyedrops.There was no significant difference of visual acuity preoperatively or at the last follow-up(t=-1.18,P>0.05).During the follow-up time,the visual acuity of 27 cases(87.10%)were maintained.No postoperative complications such as hypotonia,retinal detachment,suprachoroidal hemorrhage or endophthalmitis occurred.Conclusion ECP effectively reduces IOP of refractory glaucoma after vitrectomy and maintains visual acuity with no serious complications.
