Efficacy of combined cataract extraction and endoscopic cyclophotocoagulation for the reduction of intraocular pressure and medication burden

AIM： To report on the efficacy of combined endoscopic cyclophotocoagulation（ECP） and phacoemulsification cataract extraction（PCE） with intraocular lens placement for reduction of intraocular pressure（IOP） and medication burden in glaucoma.·METHODS： A retrospective case review of 91 eyes（73patients） with glaucoma and cataract that underwent combined PCE/ECP surgery was performed. Baseline demographic and ocular characteristics were recorded,as well as intraocular pressure, number of glaucoma medications, and visual acuity postoperatively with 12-month follow-up. Treatment failure was defined as less than 20% reduction in IOP from baseline on two consecutive visits（at 1, 3, 6, or 12 mo postoperatively）,IOP ≥21 mm Hg or ≤5 mm Hg on two consecutive visits, or additional glaucoma surgery performed within12 mo after PCE/ECP.·RESULTS： Overall, mean medicated IOP was reduced from 16.65 mm Hg at baseline to 13.38 mm Hg at 12mo（P 0.0001）. Mean number of glaucoma medications was reduced from 1.88 medications at baseline to 1.48 medications at 12mo（P =0.0003）. At 3mo postoperatively,the success rate was 73.6%（95%CI： 63.3, 81.5）, 57.1% at6mo（95% CI： 46.3, 66.6）, and 49.7% at 12mo（95% CI：38.9, 59.6）. Patient demographic characteristics were not associated with treatment success. The only ocular characteristic associated with treatment success was a higher baseline IOP.· CONCLUSION： Combined PCE/ECP surgery is an effective surgical option for the reduction of IOP and medication burden in glaucoma patients. Patients withhigher baseline IOP levels are most likely to benefit from this procedure.

Combined phacoemulsification and goniosynechialysis with or without endoscopic cyclophotocoagulation in the treatment of PACG with cataract

AIM:To investigate the efficacy and safety of combined phacoemulsification and goniosynechialysis with or without endoscopic cyclophotocoagulation(PGE group and PG group)for the treatment of patients with coexisting primary angle-closure glaucoma(PACG)and cataracts.METHODS:The clinical data of patients with PACG and cataract were retrospectively reviewed.There was a total of 88 eyes in the study and were divided into two groups,42 eyes in PGE group and 46 eyes in PG group.Surgery success cumulative survival,preoperative and postoperative intraocular pressure(IOP),number of IOPlowering medications,best corrected visual acuity(BCVA)in the two groups were observed for more than 12 mo and compared within each group and between two groups.RESULTS:The mean IOP in PGE group declined from24.9 mm Hg preoperatively to 14.1 mm Hg at the first month after operation(P<0.001)and at the last visit 16.2 mm Hg(P<0.001).Meanwhile PG group also showed significant decrease,from 24.1 mm Hg preoperatively to 13.0 mm Hg at Imo after operation(P<0.001)and 15.3 mm Hg at the last visit(P=0.004).The mean medications reliance reduced in both groups,in PGE group was reduced from 1.62 preoperatively to 0.13 at the last visit(P<0.001),in PG group from 0.87 to 0.10(P<0.001).At the last visit,BCVA increased from 0.21 to 0.60 in PGE group(P<0.001)and from 0.24 to 0.67 in PG group(P<0.001).The success rate of PGE group at 1 mo was95.2%,then decreased to 70.7%at the last visit,whereas in PG group,the success rate at 1 mo was 100%,at the last visit was 73.4%.CONCLUSION:PGE shows promise for PACG patients with cataracts to reduce IOP,lighten the medication burden and improve visual acuity,and PG still has its value in specific patients.

A review of combined phacoemulsification and endoscopic cyclophotocoagulation:efficacy and safety

As cataract occurs frequently in patients with glaucoma, combining phacoemulsification and endoscopic cyclophotocoagulation has been gaining attention recently due to its minimally invasive nature. A variety of studies had evaluated the efficacy and safety of this procedure and had shown extremely promising results. This review article has shown here that combined phacoemulsification and endoscopic cyclophotocoagulation procedure could effectively reduce intraocular pressure in medically uncontrolled glaucoma patients while avoiding serious complications associated with traditional cyclophotocoagulation procedure and adverse effects related to filtering surgery such as trabeculectomy.

Bleb-associated endophthalmitis treated by sclera patch graft, vitrectomy and endoscopic cyclophotocoagulation

Background Bleb-associated endophthalmitis （BAE） is a rare but severe complication of trabeculectomy with poor outcome. Various surgical methods were explored to treat such patients. However, there is no defined protocol. The aim of this study was to describe a new combined operation, and to demonstrate the outcome of the treatment. Methods Nine patients with BAE were enrolled in our study. The combined operation including pars plana vitrectomy （PPV）, sclera patch graft （SPG） and endoscopic cyclophotocoagulation （ECP） was used to treat these patients. Results In the follow-up of 18-24 months, all patients with the endophthalmitis were cured, the useful visual acuity was preserved in 7 patients, and the intraocular pressure （lOP） of 8 patients was controlled just after first operation, only one needed another trans-scleral cyclophotocoagulation. Conclusion This combined operation is a useful method for treating the patients with BAE, with SPG and vitrectomy to control the endophthalmitis and ECP to balance the postoperative lOP.

Outcomes of vitrectomy,complete pan-retinal photocoagulation,and endoscopic cyclophotocoagulation surgery after anti-VEGF treatment in neovascular glaucoma

Purpose:To establish a comprehensive treatment strategy and evaluate the efficacy of combination of anti-vascular endothelial growth factor(VEGF)injection,pars plana vitrectomy(PPV),endoscopic pan-retinal photocoagulation(PRP),and endoscopic cyclophotocoagulation(ECP)surgery for neovascular glaucoma(NVG)patients.Methods:This retrospective study included 30 patients(30 eyes)who were suffering from NVG and treated with PPV&PRP&ECP(ECP group,16 eyes),or Ahmed glaucoma valve implantation(Ahmed group,14 eyes).The intraocular pressure(IOP),number of postoperative anti-glaucoma medications,best-corrected visual acuity(BCVA),successful rate of surgery,and postoperative complications were recorded and statistically analyzed at the time points of preoperative,1-day,1-month,3-months,6-months,and 12-months after operation.Results:An obvious reduction in IOP and number of postoperative anti-glaucoma medications were observed in both the ECP group and Ahmed group after operation(P<0.05),and the ECP group showed a significantly lower IOP compared to the Ahmed group at the 6-months(P=0.014)and 12-months(P=0.047)postoperative time points,while there was no significant difference of medication number between the two groups except for 1-day after surgery.The BCVA showed no marked difference between the two groups preoperatively and postoperatively(P>0.05),while it was significantly improved in ECP group at 3-months(P=0.001),6-months(P=0.004),and 12-months(P=0.010)time points comparing with preoperative BCVA.The surgical success rates in ECP group were also slightly higher than Ahmed group.And the complications after operation showed no marked differences.Conclusions:The comprehensive treatment of PPV,endoscopic PRP,and ECP surgery for NVG patients after antiVEGF injection can control IOP effectively and be friendly to patients’BCVA without obvious serious complications throughout a 12-months follow-up period.
