Corneal Foreign Body CT - Causes, Symptoms and Treatment

Corneal foreign body is foreign material on or in the cornea. The most common types of foreign matter that become lodged in the cornea include small debris such as paint chips or plant matter, particles of dust, wood, metal or glass. Foreign bodies are not uncommon. In fact, they are one of the most frequent causes of visits for ophthalmic emergencies.

A corneal foreign body of any sort is generally considered a minor ocular trauma. The foreign object, even if it exits the eye on its own, may cause considerable inflammation that could result in the dilation of surrounding vessels. Swelling, redness and pain may occur in the cornea itself or also in the conjunctiva and the eyelids. If the foreign body does not exit the eye on its own, it will need to be removed. If left in the eye, a foreign body may cause infection or possibly death of vital ocular tissue.

Sometimes you can see the foreign body in the cornea. Other signs of this trauma include:

• Scratchy feeling
• Sensitivity to light
• Difficulty opening eye
• Sharp pain
• Burning
• Blurred or impaired vision
• Blood in the white of the eye

Should you experience a corneal foreign body, avoid rubbing the affected eye as this may cause abrasion of sensitive eye tissues. Rinse the eye with clean water or artificial tears. If you or an observer can see the foreign body, call Dr. Gold's office for immediate removal. Most often, foreign bodies are easily removed with specialized instruments. Your doctor will numb your eye before removal for your comfort and peace of mind. You may also be prescribed antibiotic eye drops in order to prevent infection.

While there is no guarantee that you can avoid the occurrence of a foreign body entering your cornea, there are safety measures you can take to improve your chances. When performing some task where wind or other propellant may blow, wear proper eye gear. This could include wearing standard sunglasses when enjoying a Sunday ride on a motorbike or in the car with the top down. When working near machinery where drilling, cutting or sanding is done, safety goggles are recommended. By taking the appropriate precautions, your eyes are better protected.
