Bilateral Iris Metastasis From Pulmonary Adenocarcinoma
Peng Lu, MD; Jingjing Huang, MD, PhD
Figure. Slitlamp photographs revealed diffuse iris metastasis in the right eye that manifested as a well-defined, semitransparent, jellylike lobular nodule, with iris pigment depositing on its surface (inset).
A man in his 60s presented with blurred vision without pain for 1 month. Visual acuity was 20/40 OU, and intraocular pressure was 37 OD and 46 OS. The patient was diagnosed with histopathologi- cally confirmed pulmonary adenocarcinoma with multiple metas- tases including in his brain. On examination, semitransparent, jelly- likeirisneoplasmsofvaryingsizesandshapeswerefoundinmultiple quadrantsofbotheyes(Figure).Theanteriorchamberangleswere openedinbotheyesbygonioscopy.Dilatedfundusexamination,ul-
