Objective To investigate the causes of failure of the primary vitrectomy,sum up the experience for secondary vitreous surgery and improve the success rate of primary vitrectomy for complicated retinal detachment． Methods The records of a consecutive series of 60 patients(65 eyes)that underwent secondary vitreous surgery between 1997 to 1998 were retrospectively reviewed.The age of patient ranged from 9 to 63 years(mean 36),and the followup period ranged from 3 to 18 months(mean 10.5 months). Results The main causes of failure of the primary vitrectomy were postoperative recurrence of proliferative vitreoretinopathy(PVR),unwell closed retinal breaks,and intra-and postoperative complications.In 46 of 65 eyes the retina was reattached after secondary vitreous surgery(70．1%)．Postoperatively,31 eyes (47.7%) had a visual acuity(VA)improved,16 eyes(24.6%)had a VA unchanged,and 18eyes(27.7%)had a VA reduced．Fifteen eyes(23.1%)had a VA of ge;0.05 and the best VA was 0.4．Thirty-nine eyes were followed-up from 3 to 18 months(mean 10.5)．In 35 of 39 eyes,the retina was reattached(89.7%),26 eyes(40%)had a VA of ge;0.05,and 7 eyes(10.7%)were hypotonic. Conclusions The keys to the success of secondary vitreous surgery are to restore the mobility for retina by eliminating the PVR completely,and avoid intraoperative complicattions by choosing the appropriate closure procedure for retinal breaks and the suitable intraocular tamponades.

Abstract:Five eyes of acute retinal necrosis(ARN)with multiple retinal breaks and retinal detachment were treated by closed vetrectomy combined with encircling buckle,gas/fluid exchange,nolaser and cryotherapy.After operation,the detached retinas reattached in 4eyes,and among them th visual acuity was 0.2 in 1 eye,and better than 0.05 in 3 eyes.The follow-up duration in 5 eyes was from 6 to18 months and recurrent retinal detachment was found in one eys. （Chin J Ocul Fundus Dis,1996,12: 20-21)
Objective To discuss the treatment of retinal detachment(RD) after posterior chamber intraocular lents(PCIOL) implantation. Methods Twenty eyes with RD after PCIOL inplantation which were treated with vitrectomy combined with scleral buckling and intraocular tamponade from March 1993 to June 1997 in this institute were analysed retrospctively. Results The retinas reattached completely in 16 eyes and partly in 2 eyes after RD operation.The postoperative visual acuity improved in 17 eyes,not improved in 2 eyes,and decreasde in 1 eyes.The PCIOL was taken off during RD operative in 6 eyes.Postoperative complications including displacement of the PCIOL in 2 eyes,hyphema and vitreous hemorrhage were found in this series of RD operation in 1 eyes. Conclusion Vitrectomy combined with scleral buckling and intraocular tamponade is one of the effective methods to treat the eyes with RD with PCIOL. (Chin J Ocul Fundus Dis,1998,14:165-166)
