Description
Mizuho Mitamura and four co-authors report two cases of a rare benign eye tumor near the optic disc, in a 2025 paper. Such tumors are hard to diagnose from appearance alone. Both patients were women, one in her seventies and one in her thirties. Several imaging methods were applied to each tumor.
Cross-section scans showed inner retinal thickening in the first case. Dye tests showed dark early phases there. The second tumor was bright and partly calcified on scans, and it leaked dye late. A flow imaging method painted both tumors cold, meaning slow blood flow. Neither tumor changed over more than six months of watch. The authors say combined imaging supports the diagnosis. Slow, steady flow fits the tumor's stable nature.
