To present the first documentation of iris retraction syndrome in eyes with nonrhegmatogenous retinal detachment.
One patient with age-related macular degeneration and another with panuveitis developed exudative retinal detachment with iris retraction configuration. Ultrasound biomicroscopy was performed to investigate the anatomic relationship of structures in the anterior segment of the eye.
Ultrasound biomicroscopy demonstrated a severe backward bowing of the peripheral iris with irido-ciliary body and irido-zonular contact as well as broad iris lens touch. The iris retraction syndrome resolved after pupil dilation and disruption of the pupillary adhesions in both cases. The retinal detachment resolved several months later, without surgery.
Iris retraction syndrome appears not to be exclusive to rhegmatogenous retinal detachment but can present in eyes with exudative - nonrhegmatogenous retinal detachment. Thus, when the configuration of the iris shows bowing in patients with retinal detachment, iris retraction syndrome should be considered and prompt pupil dilation should be carried out.
首次记录非孔源性视网膜脱离眼中的虹膜后缩综合征。
1例年龄相关性黄斑变性患者和另1例全葡萄膜炎患者发生了伴有虹膜后缩形态的渗出性视网膜脱离。进行超声生物显微镜检查以研究眼前节结构的解剖关系。
超声生物显微镜检查显示周边虹膜严重向后弯曲，伴有虹膜睫状体和虹膜悬韧带接触以及广泛的虹膜晶状体接触。两例患者经瞳孔扩张和瞳孔粘连松解后，虹膜后缩综合征均得到缓解。数月后视网膜脱离自行消退，未行手术治疗。
虹膜后缩综合征似乎并非孔源性视网膜脱离所特有，也可出现在渗出性（非孔源性）视网膜脱离的眼中。因此，当视网膜脱离患者的虹膜形态出现弯曲时，应考虑虹膜后缩综合征，并应立即进行瞳孔扩张。
