Intraocular foreign body (eye)

Description

Intraocular foreign body (IOFB) injuries vary in presentation, outcome, and prognosis depending on various factors. Increased awareness about eye protection, improved surgical techniques, and advancements in bioengineering are responsible for an improved outcome in injuries with IOFB . The limiting factor is still the extent of the initial injury.

Symptoms include redness, foreign body sensation, increased tearing, eye pain, decreased vision, light sensitivity.

Causes and Risk factors

IOFBs such as inert substances such as glass, stone, and plastic and are better tolerated than metals that oxidize such as copper or iron. Metallic and magnetic IOFBs are the most common. Organic material such as vegetable matter, cilia causes severe tissue reaction and may lead to endophthalmitis.

Of the penetrating injuries, 18-40% have at least one IOFB. Most common age group affected by IOFB injuries is middle age (20-40 years). Most injuries occur at work using various tools with metal striking metal such as hammer and chisel.

Diagnosis and Treatment

Careful examination of eyebrows/lids for any lacerations/small foreign bodies is must. Slit lamp examination usually is able to locate an IOFB in the anterior segment.

There are foreign objects that may accidentally enter the eye (eg, genes) that can be easily removed even by the patient at home. It is advisable to rinse the first periocular region and even eye with saline (same solution used for washing contact lenses). If such a solution is at hand, can be replaced with distilled water or, in extreme situations, with tap water. However, it is recommended, if possible, avoid using tap water due to its chlorine content.

Systemic and topical antibiotic therapy may be started prior to the surgical intervention. Topical corticosteroids are also important to minimize the inflammation. A tetanus booster may also be appropriate. ...
