We report the case of a myopic patient who, after intraocular lens transplant in the posterior chamber, suffered elevated intraocular pressure due to pigment dispersion, with recurrent episodes of blurred vision. The patient was treated with a new surgical technique that can avoid potential iridolenticular contact.
Complete ophthalmologic examination and optical coherence tomography (OCT) of the anterior segment were performed.
Contact between the pigmentary epithelium and the iris with an intraocular lens was revealed by utrasound biomicroscopy and OCT. In this case, Nd:YAG laser iridotomy and laser iridoplasty were not effective for iridolenticular separation and control of the pigment dispersion. We propose a new technique: stitches on the surface of the iris to obtain good iridolenticular separation and good intraocular pressure control.
Stitches on the iris surface should be considered as optional therapy in pigmentary glaucoma secondary to intraocular lens implantation. This surgical technique can avoid potential iridolenticular contacts more definitively.
我们报告了一例近视患者，该患者在进行后房型人工晶状体移植后，因色素播散导致眼压升高，并伴有视力模糊反复发作。该患者接受了一种可避免潜在虹膜晶状体接触的新手术技术治疗。
进行了全面的眼科检查及眼前节光学相干断层扫描（OCT）。
超声生物显微镜和OCT显示色素上皮与虹膜及人工晶状体之间存在接触。在该病例中，钕:钇铝石榴石（Nd:YAG）激光虹膜切开术和激光虹膜成形术对于虹膜晶状体分离及色素播散的控制无效。我们提出一种新技术：在虹膜表面缝合，以实现良好的虹膜晶状体分离及眼压控制。
虹膜表面缝合应被视为人工晶状体植入后继发性色素性青光眼的一种可选治疗方法。这种手术技术能更确切地避免潜在的虹膜晶状体接触。
