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.Conclusion: 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.Keywords: eye, cataract surgery, iris, tumour, glaucoma, Soemmering ring
