Foveal Protection with Viscoelastic Material during Removal of Posterior Segment Foreign Bodies
نویسندگان
چکیده
Foreign bodies may drop during removal from the posterior segment and result in foveal damage. Due to high specific gravity and viscosity, ophthalmic viscosurgical devices (OVDs) can dampen and redirect the force of the dropping foreign body and therefore protect the fovea. Herein we describe our technique of foveal protection with OVDs and briefly demonstrate the results in five eyes with large posterior segment foreign bodies.

Minimally Invasive Surgery for the Removal of Posterior Intraocular Foreign Bodies
This is a prospective clinical assay that included six patients who were diagnosed with penetrating corneal injury, traumatic cataract, and posterior segment intraocular foreign body (IOFB). Following anterior segment repair and extraction of traumatic cataract by clear cornea phacoemulsification, a standard 25-gauge transconjunctival pars plana vitrectomy was performed to find and release the ...
متن کاملLate complications from posterior segment intraocular foreign bodies with particular reference to retinal detachment.
During the first half of the 20th century there was a strong controversy over the route for removal of an intraocular foreign body (IOFB) lying in the posterior segment of the eye. In the early years the anterior route was substantially the method of choice (Barkan and Barkan, 1927; Verhoeff, 1932; Duggan, I933; Trevor-Roper, i944; and others). The posterior route had been advocated by Stieren ...
متن کاملVitrectomy for Removal of Posterior Segment Intraocular
I ntraocular foreign bodies (IOFBs) present unique surgical challenges, particularly when the posterior segment is involved. Risk factors for IOFB after ocular injury include youth, male gender, work-related injury, metallurgy, and battlefield or blast injury. If either traumatic endophthalmitis or traumatic cataract is present, there should be a high index of suspicion for IOFB, and imaging st...

متن کاملLate onset of rhegmatogenous retinal detachments after successful posterior segment intraocular foreign body removal.
BACKGROUND/AIM A lack of data exists concerning the development of late postoperative, non-proliferative vitreoretinopathy (PVR), rhegmatogenous retinal detachments (RRDs) after successful posterior segment intraocular foreign body (PSIOFB) removal. The authors present a series of PSIOFB cases over several years with posterior hyaloid separation resulting in RRD in two patients, 4 and 8 months ...
