Abstract
Penetrating ocular injuries with intraocular foreign bodies may result in severe visual loss. The posterior segment IOFBs are best treated by pars plana vitrectomy.To correlate the shape, size and location of posterior segment intraocular foreign bodies with visual outcome and its prognostic factors.Tertiary care center of ophthalmology, Ahmedabad , India This is a prospective study of 40 eyes of 40 patients who underwent Pars Plana Vitrectomy for the removal of posterior segment intraocular foreign bodies in Regional Institute of India. We studied the following parameters: age, gender, wound site, IOFB characteristics (shape, size, location), initial and final visual acuity.Among the study participants, 19 worked in factories, 6 were housekeepers, 7 were farmers and the remaining 5 patients were either unemployed or retired at the time of the injury. The foreign body was embedded in the surface of the retina (32.5%), located in the vitreous (55%) and in the sclera (12.5%). Nine patients (22.5%) developed delayed Retinal Detachment, which was the largest single cause of blindness in this group.Our study concludes that the larger the size of posterior segment IOFB, presence of pre-existing or secondary RD, vitreous hemorrhage poorer the prognosis. We also emphasize the use of protective eye equipments at workplace in preventing this disability caused by penetrating ocular injury.

Penetrating ocular injuries with intraocular foreign bodies may result in severe visual loss
Detachment, and even more serious complications such as endophthalmitis 3–5 The objectives of this study were to identify the prognostic factors and evaluate the visual outcomes in posterior segment intraocular foreign body (IOFB) patients managed by pars plana vitrectomy (PPV). 6
In agreement with previous reports (Heimann et al 1983; Karel & Diblik 1995), our results showed that retinal detachment (RD) was a crucial factor for poor visual outcome after IOFB injuries. 17
Summary
Penetrating ocular injuries with intraocular foreign bodies may result in severe visual loss. Aims: To correlate the shape, size and location of posterior segment intraocular foreign bodies with visual outcome and its prognostic factors. Setting and Design: Tertiary care center of ophthalmology, Ahmedabad , India Materials and Methods: This is a prospective study of 40 eyes of 40 patients who underwent Pars Plana Vitrectomy for the removal of posterior segment intraocular foreign bodies in Regional Institute of India. Penetrating ocular injury with an associated retained intraocular foreign body (IOFB) is an important cause of blindness and ocular morbidity in the working age population. 2. Ocular injuries caused by IOFBs are often associated with corneal and scleral penetrating injury, hypheama, vitreous hemorrhage, lens injury, retinal damage or detachment, and even more serious complications such as endophthalmitis 3–5 The objectives of this study were to identify the prognostic factors and evaluate the visual outcomes in posterior segment IOFB patients managed by pars plana vitrectomy (PPV).
