Abstract：
The authors describe a case of reverse pupillary block with pigment dispersion following sequential phakic intraocular lens (pIOL) implantation for high myopia, in a young female patient. The intraocular pressure (IOP) elevation began 3 weeks postoperatively, for which Nd-YAG laser peripheral iridotomies (PIs) were attempted elsewhere. Despite maximum medical therapy, the IOP was uncontrolled. She was referred to our institute for further management. Examination showed anteriorly displaced iris-pIOL diaphragm, iris pigment dispersion and raised IOP. The PIs were incomplete. Based on clinical evaluation and investigations, we concluded that the excess area of contact of the posterior iris over the pIOL caused a reverse pupillary block and pigment dispersion. The IOPs were controlled by repeating laser iridotomies and with medical therapy. Subsequently, the patient developed a low lens vault leading to bilateral cataract. Sequential explantation of the pIOL along with cataract extraction was performed and her vision was restored.
摘要：
作者描述了在连续有晶状体眼人工晶状体（pIOL）植入高度近视后，伴有色素分散的反向瞳孔阻滞的情况。一个年轻的女性患者。术后3周开始眼内压（IOP）升高，为此，在其他地方尝试了Nd-YAG激光外周虹膜切除术（PIs）。尽管有最大的药物治疗,IOP不受控制。她被转介到我们研究所接受进一步管理。检查显示虹膜-pIOL隔膜前移，虹膜色素分散和IOP升高。PI是不完整的。根据临床评估和调查，我们得出的结论是,后虹膜在pIOL上的接触面积过多导致反向瞳孔阻滞和色素分散.通过重复激光虹膜切除术和药物治疗来控制IOP。随后，患者出现低晶状体拱顶,导致双侧白内障.在白内障摘除术的同时进行了pIOL的顺序移植，并恢复了视力。
