Article Abstract

Computed tomography (CT) revealed a 2-cm linear area of extremely low attenuation in the left orbit of a boy who had been poked in the eye with a tree branch. The appearance and attenuation of the area suggested air, so a diagnosis of orbital emphysema was initially considered. Further research indicated that wood mimics the CT attenuation and appearance of air. A wood splinter was surgically removed from the orbit.

Background: Intraorbital wooden foreign bodies (IOWFBs) constitute a relatively rare ocular trauma. Clinically, it can be difficult to diagnose them due to their wide variety of clinical manifestations. In addition, radiologic diagnosis of IOWFBs is always uncertain and challenging since their low density and low intensity on initial images are identical to air and fat.

The authors report a case of an intraorbital wooden foreign body that was misinterpreted as a radiolucent area of retained air on a computed tomography (CT) scan. A 20-year-old soldier presented to an outpatient clinic following an impingement with a bough while cutting down a tree. He had a 1-cm-deep laceration on the inner canthal area of his right eye.

Background: Orbital 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 Methods: We 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.

Introduction: To investigate the clinical manifestations, diagnosis, and surgical treatment of intraorbital foreign bodies (IOFBs).

Methods: Patients with IOFBs were enrolled from Wuhan Union Hospital between January 2011 and January 2021. Demographic and clinical information was extracted, including gender, age, cause and entrance of the trauma, material, size and quantity of foreign body, visual function, ocular complications, imaging findings, and surgical intervention.

Graves’ orbitopathy (GO) is an extrathyroidal manifestation of Graves’ disease (GD), which can be associated with corneal ulcerations or optic neuropathy in severe forms. Transnasal endoscopic orbital decompression (TEOD) is a surgical procedure performed in order to decrease the intraorbital pressure by removing part of its bony borders in cases with excessive mass in orbit. The aim of this study was to present the results and evaluate the efficacy of TEOD for GO.
