Pupilloplasty in a patient with true polycoria: a case report

ABSTRACT Here we report a case of surgical pupilloplasty in an adult with true polycoria. A 44-year old man was referred to our clinic with a best-corrected visual acuity (BCVA) of 0.5 diopters (D) in his left eye. Biomicroscopy revealed two pupils within a 2.5-mm central zone, with diameters of 1.2 and 1.1 mm. Both pupils had real iris sphincters and responded to light and chemical stimulation. Therefore, we surgically cut the bridge between the two pupils without any intraoperative or postoperative complications. One month after the surgery, BCVA had improved to 0.9 D, and the final pupil was almost round, measuring 2.7 mm in diameter.

摘要 本文报告1例成人真性多瞳孔症（true polycoria）患者行手术瞳孔成形术（surgical pupilloplasty）的病例。患者为44岁男性，因左眼最佳矫正视力（best-corrected visual acuity, BCVA）为0.5屈光度（diopter, D）就诊于我院门诊。裂隙灯显微镜检查（biomicroscopy）显示，虹膜中央2.5mm范围内存在两个瞳孔，直径分别为1.2mm与1.1mm。两个瞳孔均各自拥有完整的虹膜括约肌（iris sphincter），且对光刺激与化学刺激均产生反应。遂通过手术切断两瞳孔间的虹膜桥组织，术中与术后均未发生任何并发症。术后1个月，患者左眼最佳矫正视力提升至0.9屈光度，成形后瞳孔近似圆形，直径为2.7mm。
