Abstract
PURPOSE: To report a case of siderosis from a retained intraocular iron foreign body manifesting localized retinal capillary nonperfusion documented by fluorescein angiography. METHODS: Case Report. In a 35-year-old man with decreased vision in the left eye, studies included fundus photography, fluorescein angiography, visual field testing, and electrophysiology. Surgical foreign body extraction and histopathologic examination were performed. RESULTS: Preoperatively, in the left eye, humphrey visual fields and electrophysiology testing revealed marked depression. Fluorescein angiography demonstrated nasal capillary nonperfusion with occlusion of the second- and third-order arterioles extending along a gradient from the foreign body. Microscopic examination of the lens capsule confirmed the diagnosis of siderosis secondary to a retained iron foreign body. CONCLUSION: Extensive capillary nonperfusion may be associated with a retained iron intraocular foreign body, as documented by fluorescein angiography.
