To determine the surgical success of 25 G vitrectomy surgery for primary retinal detachments
A retrospective chart review of a consecutive series of patients undergoing 25G vitrectomy surgery for retinal detachments was completed.The inclusion criteria included primary retinal detachment,PVR grade C2 or less, and phakic or pseudophakic status. The exclusion criteria were trauma,diabetes,PVR gradeC3 or greater,scleral buckle and previous vitreoretinal surgery.
169 consecutive patients were identified.The age range was 17-87 years of age with a median age of 59.The followup period ranged from 0-82 weeks.155 patients were successfully reattached with 1 25g vitrectomy surgery. The number of tears identified per patient ranged from 1-8 with the medial of 2 tears.14 (9%)patients had a redetached.The redetachment was attributed to a new tear (8 pts.),PVR(6 pts.),inferior tear/hole(5 pts.) Of those that redetached 6 patients were reattached with one repeat 25G vitrectomy surgery while 8 patients required a combined vitrectomy/scleral buckle surgery.60/169 patients had a followup of 12 weeks or greater. In this group the pre-operative visual acuity ranged from 20/20-HM with a median of 20/200.34/60 patients were classified as macula off detachments.The post-operative visual acuity ranged from 20/15-CF with a median of 20/40.
Primary 25G vitrectomy surgery appears to be a safe and effective surgical approach to primary retinal detachments in phakic and pseudophakic patients.The reattachment rate and the visual outcome appear to be as good as the rates reported with scleral buckle alone and scleral buckle combined with vitrectomy.
