Abstract Details

Purpose:

To highlight the importance of thorough imaging assessment in investigating patients with intraocular foreign body, when it is not visible in biomicroscopy.

Setting:

Department of Ophthalmology, Hippokration General Hospital of Thessaloniki, Thessaloniki, Greece

Methods:

Male 67 years old presented to ophthalmological emergency department complaining of blurred vision of the right eye (OD) after reported injury from foreign body (soil clod). Visual acuity was 5/10 (OD) and 7/10 (OS). Intraocular pressure of the right eye was elevated (30mmHg). On examination right upper eyelid edema, ecchymosis and ipsilateral blepharoprosis were present. Slit lamp examination was normal except for subconjunctival haemorrhage. Dilated fundus examination showed superior peripheral preretinal haemorrhage. No sign of foreign body or entry site was visible on biomicroscopy.

Results:

Orbital computed tomography (CT) with axial and coronal cuts was performed, which revealed the presence of a radiodense intraocular foreign body located inferonasally adjacent to the zonule of Zinn without damaging the lens or the capsule. The patient was planned for surgery under general anesthesia and the foreign material was extracted with application of a magnet through a sclerotomy. Retinal cryotherapy was performed afterwards.

Conclusions:

The presence of an intraocular foreign body should always be examined in case of eye injuries especially with material of unknown origin and nature. Neuroimaging studies and especially CT are priceless in the detection and localization of intraocular foreign bodies.
