Clinical Presentation

Overview

A retained magnetic foreign body in the vitreous body typically results from ocular trauma, often seen in individuals who work in environments where metal fragments can become airborne, such as construction sites or metalworking facilities. The foreign body may be a result of an injury that occurred some time ago, hence the term "old."

Patient Characteristics

• Demographics: This condition is more prevalent in males, particularly those aged 20 to 50 years, due to higher exposure to occupational hazards.
• Occupational Risk: Patients often have jobs that involve metalwork, welding, or other activities where metal fragments can enter the eye.
• History of Trauma: A significant number of patients will have a documented history of ocular trauma, which may have been overlooked or inadequately treated at the time of injury.

Signs and Symptoms

Common Symptoms

1. Visual Disturbances: Patients may report blurred vision, floaters, or flashes of light. These symptoms arise from the presence of the foreign body in the vitreous, which can interfere with light transmission to the retina.
2. Eye Pain: While some patients may experience minimal discomfort, others may report significant pain, especially if there is associated inflammation or secondary complications.
3. Photophobia: Increased sensitivity to light can occur, leading to discomfort in bright environments.
4. Redness and Swelling: Conjunctival injection (redness) may be observed, particularly if there is associated inflammation.

Physical Examination Findings

• Fundoscopic Examination: An ophthalmologist may observe the foreign body within the vitreous cavity during a dilated fundoscopic exam. The foreign body may appear as a dark spot against the lighter background of the vitreous.
• Vitreous Hemorrhage: In some cases, bleeding into the vitreous may be noted, which can further complicate the clinical picture.
• Retinal Damage: There may be signs of retinal detachment or other retinal injuries, which can occur due to the foreign body’s presence or movement.

Diagnostic Considerations

Imaging Studies

• Ocular Ultrasound: This non-invasive imaging technique can help visualize the foreign body and assess its location and any associated complications, such as retinal detachment or vitreous hemorrhage.
• CT Scan: In cases where the foreign body is suspected to be metallic, a CT scan can provide detailed information about its size, shape, and exact location within the eye.

Differential Diagnosis

• Conditions such as retinal detachment, vitreous hemorrhage from other causes, or other types of intraocular foreign bodies should be considered when evaluating a patient with symptoms suggestive of a retained magnetic foreign body.
