Clinical study on cryotherapy for treatment of retinal detachment due to dialysis of ora serrata under surgical microscope with wide field inversion lens system

Abstract

Objective To evaluate the value of cryotherapy for treatment of retinal detachment due to ora serrata dialysis under surgical microscope with wide field inversion lens system.Methods The wide field inversion lens system with cryoretinopexy under microscope were applied in 24 eases (24 eyes) with ora serrata dialysis.The operative effect,time of cryotherapy and complication were analyzed.Results Followup was from 6 to 38 months,22 of 24 cases (91.7％) achieved retinal reattachment after the initial surgery,2 of 24 cases achieved retinal reattachment after the twice surgery.The bindness rate reduced from 75％ to 33 ％ (x2 =7.954,P ＜ 0.01 ).The operative time of cryotherapy was 5.0 ± 1.2 minutes.There was no severe complication.Conclusion The wide field inversion lens with cryoretinopexy under microscope applied in ora serrata dialysis that can simplify operational procedure,shorten surgical time and decrease complication.
