Comparison of 20-, 23-, and 25-gauge pars plana vitrectomy in pseudophakic rhegmatogenous retinal detachment repair

Ophthalmic Surg Lasers Imaging. 2011 Mar-Apr;42(2):107-13. doi: 10.3928/15428877-20101223-02. Epub 2010 Dec 30.


Background and objective: To compare 20-, 23-, and 25-gauge pars plana vitrectomy (PPV) for repair of primary pseudophakic rhegmatogenous retinal detachment.

Patients and methods: One hundred eyes of 94 pseudophakic patients who underwent primary rhegmatogenous retinal detachment repair with 20-, 23-, or 25-gauge transconjunctival PPV without scleral buckling were included. The medical records were retrospectively reviewed and the corresponding demographic information, preoperative ophthalmic diagnoses, surgical management, and postoperative course and treatment were recorded.

Results: Retinal detachment repair was performed by one of four surgeons. All eyes underwent primary vitrectomy using either 20-, 23-, or 25-gauge vitrectomy instruments, a wide-angle viewing system, endolaser photocoagulation, and gas or silicone oil tamponade. Single surgery anatomical success was 25 of 28 eyes (89.3%) for 20-gauge, 24 of 27 eyes (88.9%) for 23-gauge, and 42 of 45 eyes (93.3%) for 25-gauge PPV. There was no statistical difference in single operation success or final visual acuity results between the groups and 100% of patients achieved final reattachment.

Conclusion: Twenty-, 23-, and 25-gauge instruments are equally effective options for primary repair of pseudophakic rhegmatogenous retinal detachment.
