Use of 25-gauge transconjunctival sutureless vitrectomy resulted in shorter operating times and faster visual recovery in patients with diabetes mellitus compared with standard 20-gauge pars plana vitrectomy.

Patients in a study of 45 eyes in 44 consecutive patients who underwent 25-gauge transconjunctival sutureless vitrectomy had an average operation time of 43 minutes compared with 59 minutes in patients who underwent procedures using 20-gauge pars plana vitrectomy.

Final visual acuity was similar between the two groups: 0.60 logMAR at 6 months in the 20-gauge group and 0.58 logMAR in the 25-gauge group. However, at 1 week and 1 month, visual acuity was lower in the 25-gauge group (0.95 logMAR and 0.75 logMAR, respectively) compared with the 20-gauge group (1.30 logMAR and 0.95 logMAR, respectively).

There were no serious intraoperative complications in either group, and postoperative complications were infrequent and similar between the two groups, according to the study.
