A clinical analysis of subclinical siderosis and secondary glaucoma

: In this study, we reported 6 cases of retained iron-containing intraocular foreign body with no signs of siderosis but manifestations of secondary open angle glaucoma. The clinical characteristics and the possible mechanism of this form of glaucoma were described. It is proposed to name this special and easily neglected glaucoma "subclinical siderosis secondary glaucoma".
