Abstract :
Purpose: To evaluate the accuracy of ocular sonography in measurement of size of intraocular foreign bodies (IOFB)Methods: In a case series study, 58 consecutive patients with intraocular foreign body were included. Ocular sonography was performed to detect intraocular foreign body and the results were compared with the same intraoperative findings.Results: Metallic material was found to be the most prevalent one (71%) followed by glasses (12%), stone (8%) and wood (6%). Ultrasound localized the foreign body lodged in the lens in 10.3%, in the angle in 3.4% and in the vitreous or vitreoretinal region in the rest of them (86.3%). The mean size measured by ocular sonography was 3.5×4.5 mm and that was reported by the surgeon was 2.9×4 mm. While the reports of sonography in detection and localization of IOFB was completely comparable with surgical findings, size measurements were considerably different from true measurements after intraocular surgery.Conclusion: Ocular sonography showed mostly overestimation in measuring intraocular foreign bodies. Although ocular sonography was one of the best methods for assessment of IOFB, it doesn t have high accuracy in estimation of size of IOFB
