Abstract:
AIM: To compare the efficacy, safety, and complications of 27G and 25G vitrectomy in the treatment of rhegmatogenous retinal detachment(RRD)involving the macular area.METHODS:This retrospective study analyzed 60 patients(60 eyes)initially diagnosed with RRD involving the macular area and undergoing 25G or 27G vitrectomy combined with retinal reattachment at our hospital from January 2021 to December 2023. Patients were divided into 25G group(30 eyes)and 27G group(30 eyes). Best corrected visual acuity(BCVA), intraocular pressure(IOP), surgical duration, retinal reattachment rate and complications of both groups of patients were compared before and after surgery.RESULTS: The mean surgical time in the 27G group was slightly longer than in the 25G group(40.20±7.52 vs 36.97±7.47 min). Incision leakage occurred in 7 eyes(23%)in the 25G group versus 1 eye(3%)in the 27G group, though the difference was not statistically significant between two groups(P>0.05). At 6 mo postoperatively, BCVA(LogMAR)improved significantly in both groups(27G: 0.37±0.19 vs preoperative 0.98±0.32; 25G: 0.40±0.17 vs preoperative 0.84±0.33; all P<0.05), with no statistical difference in BCVA(P>0.05). At 1 d postoperatively, the 25G group had lower mean IOP(12.29±2.86 mmHg)compared to the 27G group(15.87±3.70 mmHg; P<0.001), but no differences were observed at 1 wk or 1 mo postoperatively(all P>0.05). Retinal reattachment rates and complications(intra- or postoperative)showed no significant intergroup differences(all P>0.05).CONCLUSION: Both 25G and 27G vitrectomy are safe and effective in treating rhegmatogenous retinal detachment. However, the 27G vitrectomy offers advantages such as small incisions, better self-sealing properties, and more stable IOP.
