Comparison of efficacy between 27G and 25G vitrectomy for proliferative diabetic retinopathy

Abstract

Objective To compare the efficacy between 27G and 25G vitrectomy for the treatment of proliferative diabetic retinopathy (PDR). Methods The data of 185 eyes of 185 cases of PDR who received vitrectomy in this hospital from Jan. 2017 to Dec. 2017 were analyzed retrospectively. All cases were divided into two groups. There were 64 eyes in the 27G vitrectomy group and 121 eyes in the 25G vitrectomy group. Results There was no significant difference in the preoperative baseline data between the two groups (P>0.05). The difference of postoperative score of symptoms, operation time, intraocular pressure, reoperation rate because of retinal detachment and vitreous hemorrhage were all not statistically significant between the two groups(P=0.070, 0.367, 0.503, 0.667). Conclusion 27G and 25G are equally safe and effective in the treatment of diabetic retinopathy. Key words: Retinopathy, diabetic, proliferative; Vitrectomy, 25G, 27G; Visual acuity
