Abstract: Background/Objectives: To compare the surgical outcomes of 25-gauge (G) vitrectomy to those of 27G vitrectomy for proliferative diabetic retinopathy (PDR) with a tractional retinal detachment (TRD). Methods: Eighty-three consecutive eyes of 71 patients with PDR and TRD that underwent initial vitrectomy at the Kyorin Eye Center from June 2021 to August 2023 and were followed for ≥3 months were studied retrospectively. The surgical outcomes of the 10,000 cut/min (cpm) 25G vitrectomy (25G group, 25 eyes) to that of the 20,000 cpm 27G vitrectomy (27G group, 58 eyes) were compared. Results: The preoperative PDR status, surgical procedures, and postoperative outcomes were assessed relative to the surgical success. The 25G group had significantly more eyes with severe PDR (p = 0.010), no prior laser photocoagulation (p = 0.027), macular detachment (p = 0.006), and the use of bimanual technique (p = 0.005). However, the operative times and incidence of iatrogenic breaks were not significantly different. The visual acuity improved significantly in both groups at 3 months postoperatively. The primary anatomical success was 88% in the 25G and 97% in the 27G groups (p > 0.05). The risk factors for a postoperative retinal detachment were significantly associated with the grade (p = 0.042) and type of PDR (p = 0.041), the use of perfluorocarbon liquid (p = 0.028), and bimanual techniques (p = 0.017). Conclusions: The high anatomical success for both groups for TRD secondary to PDR indicates that both can be used to treat eyes with PDR. The 27G vitrectomy may reduce the need for bimanual techniques.
