Abstract

Purpose: We report the case of plateau iris syndrome (PIS) in a middle-aged woman, controlled by medical treatment.

Methods: Case report

Results: A 37-year-old woman, presented to our department with paroxysmal periorbital pain and progressive decline in VA in the left eye.Best corrected VA was 10/10 in both eyes.Anterior chamber(AC) was peripherally shallowed,but normal in the center bilaterally.Intra ocular pressure (IOP) was normal in OD and 38 in OS. C/d ratio was 0.3 in OD,0.4 in OS.On gonioscopy,angle was occludable in OD.In OS,it revealed convex iris,closed angle/360°,opening by indentation with double hump sign.Visual field showed no abnormalities. Bilateral laser peripheral iridotomy (LPI) was performed.Angle depth improved only in OD.The diagnosis of IPS was made.An UBM made revealed a lens volt (LV)measuring 1.11mm with an occludable angle in the OD.In the OS, LV was elevated 1.20mm, the angle was closed with peripheral anterior synechiae.Iridoplasty wasn't done.We discussed the phacoemulsification but as the patient was controlled by medical treatment and hadn't cataract, we opted to treat medically with regular controls.

Conclusions: Although PIS represents a diagnostic trap,based on a cautious anamnesis and a thorough gonioscopy,the accurate diagnosis can be made.Treatment may be challenging in some cases with many considerations.

高原虹膜综合征1例

目的：我们报告一例经药物治疗控制的中年妇女高原虹膜综合征（PIS）。方法：病例报告结果：一名37岁女性，因阵发性眶周疼痛和左眼进行性VA下降而来我科就诊。双眼最佳矫正VA为10/10。前房（AC）外周浅，但双侧中心正常。OD组眼压正常，OS组眼压38。OD组C/d比值为0.3，OS组为0.4。在角镜上，角在OD中是可闭塞的。OS显示凸虹膜，闭合角度/360°，以压痕打开，双驼峰标志。视野未见异常。行双侧激光虹膜外周切开术。角度深度仅在外径上有所改善。对IPS进行诊断。UBM显示透镜电压（LV）为1.11mm，外径有一个可遮挡角。OS中左室升高1.20mm，夹角与周围前粘连闭合。虹膜成形术没有完成。我们讨论了超声乳化术，但由于患者在药物治疗控制下，没有白内障，我们选择常规对照药物治疗。结论：尽管PIS是一个诊断陷阱，但基于谨慎的记忆和彻底的阴道镜检查，可以做出准确的诊断。在某些情况下，治疗可能具有挑战性，需要考虑许多因素。
