Abstract
Purpose :
To verify the effect of intraoperative OCT (iOCT) on vitrectomy for the treatment of proliferative diabetic retinopathy (PDR).
Methods :
This retrospective study included 98 eyes of patients with PDR (mean age, 52.5 ± 11.7 years) who were treated with vitrectomy using iOCT (iOCT group) and 80 eyes from patients with PDR (mean age, 53.1 ± 10.9 years) who were treated without iOCT (non-iOCT group). The two groups were compared for intraoperative complications, reoperation ratio, postoperative complications, operation time, and postoperative visual acuity.
Results :
The incidences of intraoperative complications were 13.8% and 17.3% (P = 0.542) in the iOCT and non-iOCT groups, respectively, and the reoperation rates were 10.0% and 5.1% (P = 0.254), respectively. The incidence of postoperative complication was [A1] 22.5% and 24.5% (P = 0.860), respectively, and there was no significant difference between the two groups. The operation time was significantly higher in the non-iOCT group (91.3 ± 31.2 min) than in the iOCT group (72.9 ± 23.9 min). Six months after surgery, the postoperative visual acuity was not significantly different between the two groups (P = 0.508).
Conclusions :
The use of iOCT reduced the operation time without affecting the incidence of intraoperative and postoperative complications, reoperation ratio, and postoperative visual acuity in patients who underwent vitreous surgery for PDR.
