In the August 2005 issue of the ARCHIVES, Drs Font and Rishi described a 43-year-old man with an intriguing medulloepithelioma of the ciliary body.1 The retina was thickened and its surface was studded with multiple nodules that, by light microscopy, corresponded to intraretinal invasion and diffuse seeding along the surface of the retina and vitreous. In addition, seedlings were found along the anterior segment structures.
