We report a rare case of ocular siderosis with delayed-onset secondary glaucoma occurring 10 years after cataract and iron foreign body removal.

Case summary

A 47-year-old male who suffered an ocular injury with an iron material to his left eye 3 years prior to his initial visit was treated in our clinic for a cataract with siderosis lentis. Ten years after he underwent cataract surgery he developed secondary open-angle glaucoma. Trabecular block taken during trabeculectomy showed no iron material, however, a fibrosclerotic change was observed.


In patients with a history of traumatic siderosis lentis, a potential risk of siderosis remains for a long period.

(B) Iron was not identified in the trabecular block (Prussian blue stain, ×400). (C) Disoriented loose fibrous tissue with some degenerative change of the trabecular meshwork (electron microscopy, ×5,000).
