Iridoschisis is a rare condition that primarily affects individuals aged 60-70 years. The predominant characteristics of iridoschisis involve the tissue splitting and separation of the iris stromal layers, often resulting in two distinct layers and the presence of floating fibers in the anterior chamber. This article reports the case of a 48-year-old male with iridoschisis with partial lens dislocation in both eyes.
Trauma is the leading factor in the development of iridoschisis. However, there is no documented case of ocular trauma in the patient's medical history. Visible white atrophic fibers were observed bilaterally in the anterior iris stroma of both eyes of the individual, accompanied by a small quantity of iris tissue within the anterior chamber. In this instance, the magnitude of the iridoschisis corresponded with the degree of lens dislocation. We were apprised that the patient had regularly used a cervical massager for a prolonged period of time, positioning it upon the ocular region. Frequent stimulation of both eyes with excessive force resulted in the development of iridoschisis and the partial dislocation of the lens.During the initial surgical procedure, phacoemulsification (Phaco) was carried out on the left eye without the placement of an intraocular lens (IOL). Following a two-month interval, we proceeded with the IOL suspension. Subsequently, the right eye underwent Phaco, accompanied by the implantation of an IOL. After closely monitoring the patient's progress for two months, it was evident that their vision had significantly improved, substantiating the success of the surgical interventions.
This finding posits that the recurrent friction applied to both eyes may induce iridoschisis and various ocular complications. In the event of ocular intricacies manifesting, expeditious medical intervention becomes imperative.
虹膜劈裂症是一种罕见的疾病，主要影响 60-70 岁的人群。虹膜劈裂症的主要特征包括组织分裂和虹膜基质层分离，常导致两层明显分离，并在前房内出现漂浮纤维。本文报告了一例双眼虹膜劈裂伴部分晶状体脱位的 48 岁男性病例。
创伤是导致虹膜劈裂症的主要因素。然而，患者的病史中没有记录到眼部创伤的情况。该患者双眼前虹膜基质可见明显的白色萎缩纤维，前房内有少量虹膜组织。在这种情况下，虹膜劈裂的程度与晶状体脱位的程度相对应。我们得知，患者长期定期使用颈部按摩器，将其置于眼部区域。频繁过度地刺激双眼导致了虹膜劈裂和部分晶状体脱位的发生。
在初次手术中，左眼行白内障超声乳化术（Phaco），未植入人工晶状体（IOL）。两个月后，我们进行了 IOL 悬吊术。随后，右眼行 Phaco 联合 IOL 植入术。密切观察患者两个月的进展情况后，发现其视力显著改善，证实手术干预取得了成功。
这一发现表明，反复摩擦双眼可能会导致虹膜劈裂和各种眼部并发症。一旦出现眼部并发症，应立即进行医疗干预。
