Abstract

A 27-year-old woman had BrightOcular iris implants placed for cosmetic purposes that changed eye color from brown to blue bilaterally. Of note, BrightOcular implants are not approved by the U.S. Food and Drug Administration (FDA) for use in the United States and have been associated with severe ocular complications. In keeping with their design, they were placed in the anterior chamber (AC) in both eyes of this patient; surgery was performed outside the United States. As has been described previously and tragically in other cases, she developed chronic inflammation, intolerable glare, angle-closure glaucoma, corneal edema, and cataracts in both eyes. For medically unmanageable elevated intraocular pressure (IOP), she underwent diode laser cyclophotocoagulation (CPC) in both eyes, and eventually, an Ahmed tube shunt (New World Medical, Inc.) was placed in the right eye. Although she was advised and urged to have the iris implants removed, despite her ocular issues, she refused removal until intolerable glare and reduced vision ensued. Ultimately, both iris implants were extracted 5 years after implantation by a U.S. surgeon; the procedures resulted in corneal decompensation and progressive cataract development. Subsequent penetrating keratoplasty (PKP) was performed for the right eye, but it failed because of contact with the glaucoma tube shunt. She sought additional consultation and presented with the following findings: corrected distance visual acuity was 20/400 in the right eye and 20/40 in the left eye, IOP of 18 mm Hg in the right eye and 16 mm Hg in the left eye, pupils were nonreactive and fixed, and extraocular muscles and central visual field were normal. Pachymetry was 868 μm in the right eye and 653 μm in the left eye. Anterior segment examination in the right eye revealed a failed corneal graft with 3+ edema, peripheral anterior synechiae (PAS) for 360 degrees, shallow AC, Ahmed tube shunt at the 11 o'clock position and remnant iris adherent to the graft-host junction for 270 degrees, 3+ posterior subcapsular cataract, and 2+ cortical cataract (Figure 1JOURNAL/jcrs/04.03/02158034-202208000-00024/figure1/v/2022-08-01T210317Z/r/image-tiff). The sclera revealed multiple circular and circumferential atrophic blue spots consistent with high-energy transscleral CPC (Figure 2JOURNAL/jcrs/04.03/02158034-202208000-00024/figure2/v/2022-08-01T210317Z/r/image-tiff). In the left eye, she had remnant fixed dilated iris for 270 degrees, missing iris superiorly for 3 clock hours, an adequate AC, and 2+ cortical cataract (Figure 3JOURNAL/jcrs/04.03/02158034-202208000-00024/figure3/v/2022-08-01T210317Z/r/image-tiff). Posterior segment examination revealed a 0.5 cup-to-disc ratio in both eyes with normal vessels, macula, vitreous, and retinal periphery, bilaterally. Given this constellation of findings, how would you proceed?

摘要

一位 27 岁的女性因美容目的植入了 BrightOcular 虹膜植入物,使双眼的眼睛颜色从棕色变为蓝色。值得注意的是,BrightOcular 植入物未获得美国食品和药物管理局 (FDA) 的批准,不能用于美国,并且与严重的眼部并发症有关。根据其设计,这些植入物被放置在这位患者的前房(AC)中;手术是在美国境外进行的。正如之前和其他病例中悲惨描述的那样,她出现了慢性炎症、无法忍受的眩光、闭角型青光眼、角膜水肿和白内障。由于无法控制的眼内压升高(IOP),她在双眼接受了二极管激光睫状体光凝术(CPC),最终在右眼放置了 Ahmed 管分流器(New World Medical,Inc.)。尽管她被建议并敦促取出虹膜植入物,但尽管她有眼部问题,她还是拒绝取出,直到无法忍受的眩光和视力下降。最终,一位美国外科医生在植入后 5 年将两个虹膜植入物取出;这些程序导致角膜失代偿和进行性白内障发展。随后为右眼进行了穿透性角膜移植术(PKP),但由于与青光眼管分流器接触而失败。她寻求进一步咨询,并出现以下发现:右眼矫正视力为 20/400,左眼为 20/40,右眼眼压为 18mmHg,左眼眼压为 16mmHg,瞳孔无反应且固定,眼外肌和中央视野正常。角膜厚度为右眼 868μm,左眼 653μm。右眼眼前节检查显示角膜移植失败,水肿 3+,周边前粘连(PAS)为 360 度,浅前房,11 点钟位置的 Ahmed 管分流器和残留虹膜附着于移植物-宿主交界处 270 度,3+后囊下白内障和 2+皮质白内障(图 1JOURNAL/jcrs/04.03/02158034-202208000-00024/figure1/v/2022-08-01T210317Z/r/image-tiff)。巩膜显示多个圆形和环状萎缩性蓝色斑点,与高能经巩膜 CPC 一致(图 2JOURNAL/jcrs/04.03/02158034-202208000-00024/figure2/v/2022-08-01T210317Z/r/image-tiff)。左眼残留固定扩张虹膜 270 度,虹膜上部缺失 3 个时钟小时,前房充足,皮质白内障 2+(图 3JOURNAL/jcrs/04.03/02158034-202208000-00024/figure3/v/2022-08-01T210317Z/r/image-tiff)。后节检查显示双眼杯盘比为 0.5,血管、黄斑、玻璃体和视网膜周边均正常。鉴于这种检查结果,你将如何进行?
