To compare pars plana vitrectomy (PPV) using balanced salt solution (BSS) infusion versus (PCPV) in eyes with SPDR and TRD.
We conducted a prospective, longitudinal, comparative, Non–randomized, study of two groups. Group I (n=15) BSS infusion and Group II(n=15) PCPV. Preoperative and postoperative evaluation included ETDRS chart visual acuity and panoramic fundus photography. Surgical technique included three ports PPV, combination of delamination, segmentation, and peeling; silicon oil tamponade and positive (+5.00 D to +6.00D)disposable contact lens in the early postoperative period if macula was attached. Minimum post–operative follow–up was 6 months. Two main outcomes were evaluated: improvement in postoperative visualacuity and retinal reattachment.
There were not juvenile diabetic patients. There was not differences between two groups preoperatively. Post–vitrectomy, 10 eyes (66.6%) in Group I had stable or improved vision whereas in Group II was observed in 13 eyes (86.6%) P= .05 More than 80% of total retinal area was attached in 14 eyes (93.3%) of group II and 10 eyes (66.6%) of group I, P= .04 There was one eye with postoperative visual acuity of no light perception in group I.
In a group of 30 eyes with PDR and TRD, PCPV had better anatomical results and better visual function than BSS infusion.
