A fixed and dilated pupil is an uncommon postoperative complication after penetrating keratoplasty (PK) for keratoconus. Although the clinical features have been well described, the precise aetiology is uncertain. We performed anterior segment fluorescein angiography in the early postoperative period on three patients who developed fixed, dilated pupils after apparently uncomplicated surgery. All of the eyes had severe iris ischaemia. A possible role for a postoperative rise in intraocular pressure in the aetiology of this syndrome is discussed.
固定性散大瞳孔是圆锥角膜穿透性角膜移植术（PK）术后罕见的并发症。尽管其临床特征已有详尽描述，但确切病因尚不确定。我们对3例术后看似无并发症却出现固定性散大瞳孔的患者在术后早期进行了眼前节荧光素血管造影。所有患眼均有严重的虹膜缺血。本文讨论了眼压术后升高在该综合征病因中的可能作用。
