Abstract:

 Objective To compare the difference of lowering effect by phacoemulsification cataract extraction combined with endoscopic cyclophotocoagulation (ECP) between 210 degree and 240 degree treatment. Design Comparative case series. Participants 70 cases (70 eyes) with refractory glaucoma in Beijing Tongren Hospital were included. Methods 70 eyes were randomly divided into two groups, 35 cases were undergoing 210 and 240 degree ECP treatment respectively. All the patients were selected by clear corneal incision phacoemulsification (PE) cataract extraction combined with ECP and goniosynechialysis. The average follow-up period was (21.69±8.93) months. Main Outcome Measures Intraocular pressure (IOP) and IOP lowering pressure medications. Result Preoperative IOP was (26.13±10.58)mmHg in group 210 degree and (24.85±10.78)mmHg in group 240 degree (P=0.620). IOP decreased (7.81±12.55)mmHg and (8.57±11.40)mmHg respectively in the two groups at last follow-up(P=0.131). The average number of medications was (2.71±1.66)in group 210 degree and (2.40±1.65) in group 240 degree before operation(P=0.429), which decreased to (0.46±0.98) in group 210 degree and (0.34±0.80) in group 240 degree at last follow-up(P=0.595). No serious complication during the operation was observed. Conclusion There was no statistical significance in the control of IOP between the 210 degree group and 240 degree group by phacoemulsification cataract extraction combined with ECP.
