Clinical Efficacy Of The Micro Endoscopic Cyclophotocoagulation Combined With Minimally Invasive Cataract Surgery For Glaucoma

Objective:This study put forward the concept of micro-endoscopic cyclophotocoagulation(ECP)and discuss the clinical efficacy and safety of micro-endoscopic cyclophotocoagulation combined with minimally invasive cataract surgery,looking forward to provide a new surgical method for the clinical treatment of glaucoma complicated with cataract.Methods:This is a retrospective study by preoperative and postoperative comparison.A retrospective analysis was made on the data of 42 cases(42 eyes)of glaucoma complicated with cataract treated by micro-endoscopic cyclophotocoagulation combined with minimally invasive cataract surgery in Shenzhen Eye Hospital from January 2018 to August 2021.The clinical data of 42 cases(42 eyes)were retrospectively observed and analyzed.The best corrected visual acuity,intraocular pressure,visual field,OCT,the number of anti-glaucoma drugs,intraoperative and postoperative complications,etc.were compared before operation with after operation,and the related data were statistically analyzed.Results:The best corrected visual acuity of 42 cases(42 eyes)was significantly improved(p<0.05),but there was no significant change on the first and second day after operation.The intraocular pressure(IOP)decreased gradually with time.On the first day after operation,IOP was significantly higher than that before operation,and began to decrease on the second day after operation.The IOP at one week,one month,three months and half a year after operation was significantly lower than that before operation(p<0.05).There was no significant difference in MD and PSD between half a year after operation and that before operation(p> 0.05);There was no significant difference in RNFL thickness between half a year after operation and that before operation(p> 0.05);The number of patients increased who use one and two kinds of drugs after operation compared with that before operation,and the difference was statistically significant(p<0.05).Six patients(14.3%)used three drugs after operation,which was significantly less than that before operation(p<0.05).There’s no patient who need to use five or six kinds of drugs after operation.The complete success rate of surgery was 23.8%,and the partial success rate of surgery was 100.0%.The failure rate of surgery was 0%.The main postoperative complications were transient ocular hypertension and anterior chamber inflammation.Conclusion:Micro-endoscopic cyclophotocoagulation combined with minimally invasive cataract surgery can effectively control the intraocular pressure of patients,improve their visual acuity,reduce the use of anti-glaucoma drugs.This operation has two characteristics:minimally invasive and micro,for patients with glaucoma and cataract,this operation can effectively achieve the therapeutic effect,and the operation time is short,with fewer postoperative complications and more convenient postoperative care.It can be used as a new choice for the treatment of glaucoma and cataract.
