摘要

Ocular trauma is among the leading causes of vision loss globally. According to the World Health Organization, approximately 55 million eyeball injuries occur each year, leading to limitations in daily activities for more than 1 day. Therefore, prompt and appropriate management is essential. A penetrating injury with an intraocular foreign body (IOFB) compromises the integrity of the eyeball and is considered a medical emergency. An IOFB can become embedded in any part of the eyeball, and 23-gauge (G) standard pars plana vitrectomy (PPV) constitutes the treatment of choice for IOFBs in the posterior segment. We present a case of a penetrating ocular injury with a large (> 5 mm) retained metallic IOFB located in the posterior segment of the eyeball, which was successfully removed through a modified scleral approach (T-shaped sclerotomy, incorporating a supplementary 1.5-mm radial incision in the pars plana region towards the limbus) during 23‑G PPV. On the basis of our case and reports from the literature, T‑shaped sclerotomy can be considered an effective and safe technique for the removal of large retained IOFBs from the posterior segment. However, the modified technique needs to be validated in a larger cohort before establishing it as the approach of choice for patients presenting with large IOFBs.
