To evaluate the anatomic and functional outcomes and the rate of complications of primary 25-gauge airbag-vitrectomy in the treatment of pseudophakic rhegmatogenous retinal detachment (PsRD) uncomplicated by severe proliferative vitreoretinopathy.
In this prospective, nonrandomized, surgical technique study, 141 eyes of 141 consecutive patients with PsRD with proliferative vitreoretinopathy grade A or B underwent primary 25-gauge airbag vitrectomy, consisting in pars plana vitrectomy performed under continuous infusion of air, and air or gas endotamponade. Eyes with minimum follow-up of 6 months were evaluated. The preoperative and postoperative characteristics were analyzed. Main outcome measures were primary anatomical success rate, defined as retinal reattachment at final follow-up after a single operation without additional surgery, visual outcome at the last follow-up visit, and rate of complications.
At six months the retina was reattached successfully after a single surgery in 98% of eyes (138/141). Recurrence of retinal detachment occurred in 3 eyes (2%) during the follow-up period, caused by proliferative vitreoretinopathy in 2 eyes and by new retinal breaks in 1 eye. After treatment, BCVA improved significantly (P < 0.000, ANOVA). Mean final visual acuity (SD) was 0.28 (0.34) logarithm of the minimum angle of resolution (logMAR) compared with 0.94 (0.84) logMAR before surgery (P < 0.001, Tukey-Kramer test). The most common postoperative complication was hypotony, detected in 4 eyes (3%) on postoperative day 1.
Primary 25 gauge airbag vitrectomy provides a high anatomic success rate in eyes with PsRD and is associated with a low rate of complications.
