Experimental ocular siderosis in the squirrel monkey.
An iron-containing foreign body retained in the eye may result in siderotic damage to several ocular structures. When the retina is sufficiently damaged, the electroretinogram (ERG) becomes non-recordable. The pathogenesis of retinal damage has not been com pletely studied, and available histopathologic material is mainly of end-stage retinal le sions in eyes that were damaged severely enough...
متن کاملDesferrioxamine in ocular siderosis: a long-term electrophysiological evaluation.
Fourteen rabbits received an intravitreal iron foreign body and were treated with desferrioxamine. Their electroretinographic (ERG) values were recorded and compared with those of an untreated group. With desferrioxamine treatment a delay of the siderotic damage and preservation of better ERG potentials is observed.
متن کاملExperimental ocular siderosis after extrabulbar administration of iron.
The authors studied the penetration of iron administered extrabulbarly into the ocular tissues of rabbits. It was found that iron passes from the orbit into the eyeball and accumulates in considerable quantities in the sclera, choroid, retina, ciliary body, and even in the vitreous and corneal epithelium. However, light microscopy failed to show any damage to the ocular tissues. The mechanism b...
متن کاملtonic pupil associated with ocular siderosis
purpose: to report tonic pupil in a patient with ocular siderosis. case report: a 12-year-old male patient presented with over-sized right pupil from two weeks before. visual acuity (va) was 10/10 in both eyes without afferent pupillary defect. anisocoria was present with the right and left pupils, measuring 5 and 3 mm in diameter, respectively. anisocoria was greater in bright light and there ...
متن کاملManagement of Ocular Siderosis: Visual Outcome and Electroretinographic Changes
Purpose. Ocular siderosis (OS) is a sight threatening complication of retained iron-containing Intraocular Foreign Body (IOFB). Successful localization of the IOFB and timely removal are crucial to its management. The purpose of this study was to review the presentation, management, and outcome of OS at our institution. Methods. A retrospective case series of eyes with OS that underwent IOFB re...
