Abstract
Purpose: :
To analyze the risk factors influencing failure of the primary vitrecotmy for simple rhegmatogenous retinal detachment.
Methods: :
We reviewed the records of 79 patients, 79 eyes with rhegmatogenous retinal detachment who had been treated by primary pars plana vitrectomy from March 2004 to June 2008.
Results: :
7 eyes(8.8%) underwent cataract surgery and primary vitrectomy at the same time. And preoperative pseudophakia was 10 eyes(12.6%). SF6 on 12 eyes(92.3%), C3F8 on 1 eye(7.6%), silicone oil on 28 eyes(35.4%) were used as the tamponade material after primary vitrectomy. The follow-up period ranged from 2 to 41 months. Retinal redetachment was 13 eyes(16.5%) in 4 weeks from operation and SF6 on 12 eyes(92.3%), C3F8 on 1 eyes(16.5%) were used as the tamponade material. All 13 eyes of retinal detachment were phakia that did not underwent catrart surgery at the same time. Preoperative inferior lattice degeneration and retinal tear was significant with retinal redetachment(p<0.05)(Table 1). The major reasons for redetachments were proliferative vitretionopathy followed by new break and the other causes(Table 2).
