To report a case of a grown Soemmering ring that manifested as an iris tumour 24 years after cataract surgery.
A case report.
A 27-year-old white man was presented with a suspected iris tumour in his left eye. He had undergone lensectomy in both eyes without intraocular lens implantation 24 years ago. Last year, he was treated by topical anti-glaucoma medication for left eye intraocular pressure (IOP) rising. Six months later, his ophthalmologist found two separate iris bumps. The patient was referred to an ocular oncologist and was to be treated with plaque brachytherapy as iris melanoma, but he denied. Ultrasound biomicroscopy (UBM) of the left eye showed significant angle narrowing due to separate ovoid hyper echoic masses behind the iris, which was clearly separated from the ciliary body. Retained and growth lens material caused a Soemmering ring to enlarge, which was the reason for glaucoma and iris bumping. The patient has been followed for more than one year without any changes being observed.
An enlarged and grown Soemmering ring should be considered in the differential diagnosis of any iris and ciliary body tumour, especially in patients who have had cataract surgery.
报告一例白内障手术后24年出现的成年索默林环,表现为虹膜肿瘤。
病例报告。
一名27岁白人男性因左眼疑似虹膜肿瘤就诊。24年前他双眼接受了晶状体切除术,未植入人工晶状体。去年,他因左眼眼压升高接受局部抗青光眼药物治疗。6个月后,他的眼科医生发现两个独立的虹膜肿块。该患者被转诊至眼科肿瘤学家处,拟作为虹膜黑色素瘤接受敷贴近距离放射治疗,但他拒绝了。左眼超声生物显微镜检查(UBM)显示,虹膜后方有两个独立的椭圆形高回声肿块,导致房角明显变窄,肿块与睫状体明显分离。残留并生长的晶状体物质导致索默林环扩大,这是青光眼和虹膜肿块形成的原因。该患者已随访一年多,未观察到任何变化。
在鉴别诊断任何虹膜和睫状体肿瘤时,尤其是有白内障手术史的患者,应考虑索默林环扩大和生长的情况。
