偽性瞳孔（偽円孔）に対するレトロイリディアン虹彩形成術：新しい低侵襲手術手技

We describe a novel, minimally invasive surgical technique termed retroiridian pupilloplasty, performed in a phakic patient with a traumatic pseudoacorea of 58 years' duration. This reproducible approach, first published of us in 2022, uses an anterior vitrector to create a neopupil without a preexisting pupillary opening through the retroiridian chamber. The procedure significantly improved visual function and cosmesis, with minimal postoperative care and rapid recovery. In this case, the procedure resulted in significant improvements in both visual function and cosmetic appearance, required minimal postoperative follow-up, and allowed for rapid recovery. From the surgeon's perspective, it was a straightforward, effective, and safe approach, representing a simple and viable therapeutic option for similar cases.
