[Diagnostics and treatment of organic intraorbital foreign bodies].

backgroundOrbital injuries with organic foreign bodies are a clinical challenge as they can cause a variety of complications and sometimes lead to irreversible visual impairment. MATERIAL AND

methodsWe report five consecutive cases of patients with organic orbital foreign bodies who presented between 2012 and 2022. Documented parameters include age, gender, time of injury, mechanism of injury, best-corrected visual acuity (BCVA), presence of pain, restriction of motility, performed imaging, location and type of foreign body, treatment and complications.

resultsThe mean patient age was 61.8 ± 32.3 years and the gender ratio was 4:1 (female:male). In 4 cases the injury had been reported on average 4.6 days (0/14 days min/max) previously. Best corrected visual acuity at first presentation was 0.5 ± 0.2 decimal and after a mean follow-up of 12.7 months (0.5/38 months min/max) at last presentation 0.67 ± 0.3 decimal (p = 0.2). The reason for initial presentation was pain (n = 3) and/or double vision (n = 2). All patients underwent computer tomography (CT). The diagnosis was confirmed in two cases by means of CT. In all five cases the foreign body material could be completely surgically removed, while one patient needed repeated surgery due to retained foreign body material. The organic foreign body material included wood (4) and wax (1). In two cases, a foreign body-induced infection was successfully treated with systemic antibiotics. There were no other complications.

conclusionIn orbital trauma a thorough wound exploration must be performed, especially if the mechanism of injury is uncertain and residual foreign bodies or a perforation injury cannot be excluded. The imaging of choice is CT, which may have to be performed again in the postoperative course.
