Iris retraction syndrome (IRS) is an uncommon condition caused by retinal detachment that is characterized by back bowing of the peripheral iris, leading to a deep anterior chamber. It is commonly associated with ocular hypotony, ciliochoroidal detachment, and anterior proliferative vitreoretinopathy. We describe a case of a 66-year-old man presenting with 2 weeks of right eye pain, redness, and iris heterochromia. The patient was diagnosed with IRS secondary to a chronic retinal detachment. Initial management with topical steroids and mydriasis allowed resolution of the iris retraction and heterochromia, normalization of intraocular pressure, and improvement of choroidal detachment. Subsequent vitrectomy with endolaser and oil tamponade led to successful detachment repair. Initial pharmacologic management allows a more controlled approach to the repair of retinal detachment associated with IRS. The patient's presentation is consistent with the hydrodynamic hypothesis of IRS.
虹膜后缩综合征（IRS）是一种由视网膜脱离引起的罕见病症，其特征为周边虹膜向后弯曲，导致前房加深。它通常与低眼压、睫状体脉络膜脱离及前部增殖性玻璃体视网膜病变相关。我们描述了一例66岁男性患者，其右眼疼痛、发红及虹膜异色2周。该患者被诊断为继发于慢性视网膜脱离的IRS。最初使用局部类固醇和散瞳治疗使虹膜后缩和异色消失，眼压恢复正常，脉络膜脱离改善。随后的玻璃体切割联合眼内激光及硅油填充使视网膜脱离修复成功。最初的药物治疗为修复与IRS相关的视网膜脱离提供了更可控的方法。患者的表现符合IRS的流体动力学假说。
