Intraretinal foreign bodies
Abstract
PURPOSE: To present our experience with the removal of intraretinal foreign bodies.
MATERIAL AND METHODS: 9 intraretinal foreign bodies were removed by pars plana vitrectomy. Laser photocoagulation of the retina surrounding the foreign body was performed either before surgery or intraoperatively (endolaser). Pars plana vitrectomy with foreign body removal through the sclerotomy site with endomagnet and/or forceps was performed. In some cases fluid-gas exchange was done.
RESULTS: The average follow-up period was 6.2 months. Seven of nine foreign bodies were magnetic and two were nonmagnetic. Five of seven magnetic foreign bodies had negative magnetic traction as the first surgical procedure. In these 9 eyes, final visual acuity was below 1/50 in 2 eyes and over 5/50 in 7 eyes.
CONCLUSION: Pars plana vitrectomy should be the method of choice in removal of intraretinal foreign bodies.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
