Summary
Surgical removal of intraretinal foreign bodies (IRFBs) using pars plana vitrectomy generally yields good visual outcomes. The method of removal, whether by external magnets or intraocular forceps, appears to have comparable results for these ocular injuries.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Traumatic Eye Injury
Background:
- Intraretinal foreign bodies (IRFBs) present a significant challenge in ophthalmic trauma.
- Prompt and effective management is crucial for preserving visual function.
Purpose of the Study:
- To describe the clinical characteristics of eyes with intraretinal foreign bodies.
- To assess the outcomes of surgical interventions for IRFBs.
Main Methods:
- Retrospective review of 34 eyes from 33 patients with IRFBs.
- Surgical removal via pars plana vitrectomy using intraocular forceps or magnetic extraction.
Main Results:
- Most IRFBs were ferromagnetic (85.3%) and removed surgically.
- Postoperative complications included macular pucker/scars (23.5%) and retinal breaks (35.3%).
- Final visual acuity of 20/200 or better was achieved in 67.7% of eyes, irrespective of IRFB characteristics or surgical timing.
Conclusions:
- Vitreoretinal surgery for IRFBs offers generally favorable anatomic and visual results.
- Surgical approach (magnets vs. forceps) did not significantly impact outcomes.
- Management decisions should consider IRFB type, size, and location.
