Eyes with epiretinal membrane and good preoperative visual acuity may have better final visual acuity outcomes after small-gauge pars plana vitrectomy, according to a study.
The retrospective chart review evaluated visual outcomes of 132 eyes that underwent 25-gauge vitrectomy and eight eyes that underwent 23-gauge vitrectomy, all with 20/50 or better preoperative visual acuity, because of symptomatic epiretinal membrane.
Overall, mean visual acuity significantly improved from 20/40 preoperatively to 20/35 at the 1-year follow-up. Of the 77 pseudophakic eyes, mean visual acuity improved from 20/40 preoperatively to 20/32 at 1 year, whereas the 63 phakic eyes only improved from a mean visual acuity of 20/41 preoperatively to 20/40 at the final follow-up.
