Pars plana vitrectomy after intraocular foreign bodies.

Pars plana vitrectomy after intraocular foreign body injuries led to a good or at least useful vision in 60% of the cases. Without exception, these were eyes which were practically blind or eyes which according to our experience would have been blinded without vitrectomy. Retinal detachments which have arisen preoperatively have a decisive negative effect on the prognosis: there is a low rate of healing in consequence of traumatic, contusional and metallotic retinal lesions and high MPP rate. Increasing surgical experience, so-called secondary vitrectomy 'in time' as well as improved and more refined vitrectomy instruments lead to better results.
